In use, as will be explained in more detail later, the lining device 50 The winch and and a cable fixed to the lining device 50 by, for example, a guide bar 85 (Fig. (not shown).

It is necessary or desirable to assist in this traction action. , a pair of toothed tractor structures 89 are provided for this purpose (FIG. 7). and Figure 8).

These tractor structures 89 are equally attached to the guide channel 74. and each disposed between each pair of hose edge cutting structures 80. .

Each tractor structure 89 includes a rotating shaft 90 having a series of gears 91 mounted thereon. 91 extends into each hose guide passage 73 and connects to the flattened hose 63. the lining device 50 along the hose 63 by scratching it. Make it move forward.

This axis 9 7 is driven by an air vane motor 100, one end of which is connected to the main housing 5. It is arranged in the recessed part 101 of No. 4.

The other end of each shaft 97 extends into the housing 94 and attaches to the chain sprocket 102. I get kicked. The two chain sprockets 102 are connected by a chain 103. This allows the gears 91 to rotate synchronously.

Air supply means to the air vane motor 58 is provided by a T-vib connection (not shown). It is connected to the Aven motor 100.

Next, with reference to Fig. 1, Fig. 12, Fig. 21, and Fig. 22, the working structure of the trowel is explained. I will explain.

Initially (see Figure 25), the troweling means is a cellulose polymer, i.e. cellophane. It is a tube of flexible, thin-walled material such as ®.

It is stretched as a flat tube as shown by 104 and first 105, The layers 107.108.10 are then laterally folded as shown at 106. Form a flat tube with 9. Then in the longitudinal direction as indicated by Jlo It is bent into an accordion shape as shown at 111.

Tube puff cage thus flattened, folded and accordion shaped 112 is inserted into a magazine box 113 having a slot outlet 114. child As shown at 115, the magazine box 113 of the centrifugal lining machine 51 is It is detachably connected or clamped to the stop shaft 61.

The magazine box 113 has a rearwardly widening opening 116 at its rear end. , on this day 116 is opened to the side, and the roller 117 is the most open part of this opening 116. It is freely rotatable and attached to the top and bottom of the area where it was placed.

A spreader guide 118 that widens toward the end is provided in the bottom 116, and this spreader guide The guide 118 has a hole as shown at 119 formed at its small end and its wide side. Rollers 120 are freely attached to the upper and lower bottoms of the ends.

Rollers 117 and 120 form the top and bottom nimbs (FIGS. 1 and 24). (see figure).

Side strap members (not shown) are provided across the cheeks of the mouth 116 and Although it is possible to hold the redder guide 118 in a predetermined position, This does not seem basic.

The spreader guide 118 is a conical trowel 122 spring-loaded by a shaft 121. The conical trowel 122 has a known structure and has an adjustable diameter. In this case, the normally closed end of the conical iron 122 is 12 Instead of the 0-conical trowel 122 provided with a hole as shown at 3, a foam A wob 124 (FIG. 21) may also be used.

The hose 63 used in the lining method according to the invention is made of polyvinyl chloride, for example. Components of a centable lining composition made of plastic materials such as oil, That is, for example, one side is an epoxy resin and the other side is a hardening material and an inorganic filler. Quantity is pre-filled. They may be filled in any convenient manner i.e. the components can be pumped into the hose or fed by gravity into the hose. or by opening the hose axially to allow filling. It can be made to seal in the direction.

Pre-filled hoses are delivered to the site in predetermined quantities.

For example, two downholes 80 to 100 meters apart cut into a sewer pipeline. Can be opened. These downholes will generally be existing manholes.

Before lining the sewer pipe 56 between the two downholes, draw it through the sewer pipe. attached to a trolley or sled, or attached to a self-propelled big As a result of this preliminary inspection, the sewer pipes would have been inspected by means of a television set. Deeply protruding side protrusions and tree roots should be cut off, and any damage caused by water intrusion etc. should be removed. leaks such as leaks are sealed, and large deformations in the cross section of the sewer pipe are corrected. i.e. the sewer pipe will be as round as reasonably possible (or made circular, e.g. Debris, such as those originating from the walls of broken sewer pipes, will be removed.

Therefore, due to the lining, it is relatively undisturbed by water and sediment debris and is reasonably round. Sewerage is provided.

After preparing the drain pipe 56 in this way, the two hoses 63 (epoxy and agent) is inserted into the drain pipe 56 and laid in parallel relationship with the bottom of the drain pipe 56. . The hose 63 is stopped at the downhole on the outlet side.

The lining device 50 and the trowel working structure together with the preceding delivery tube 62 is inserted through the downhole on the inlet side, and the description below, especially FIG. As is clear from the description with reference to , the hose 63 is cut in the axial direction, It is screwed through the lining device 50, and the screwed end is also locked to the bottom of the sewer pipe. Ru. The trowel tube 104 is pulled over the spreader guide 118 and the conical trowel 12. It can be held in an open annular shape by a fixed ring 124 (FIG. 1), or it can be Properly stopped at the wall of the water pipe.

Therefore, in this state, the leading end of the delivery tube 62 is for the forward guide. It is inserted into each hose 63 together with the sled 68 . The towing cable is in line. attached to the downhole winch on the exit side of the ground level. , the air hose and air supply device to the air vane motor 58 are further connected to the T-connection. Therefore, it is also connected to the air vane motor 100, and the air hose is also connected to the outlet side. Connected to the amplifier. The lining device 50 is installed here or prior to this. Filled with the epoxy and hardener components of the centable lining composition.

The lining operation can now be started.

The air supply to the air vane motor 58.100 is opened and the lining device 50 traction begins.

The advancing lining device 50 removes the epoxy and hardener from each hose 63. The slitter structure 69 is indicated by 125. The hose 63 is slit in the axial direction at the location where the hose 63 is inserted (FIG. 10).

The epoxy and curing agent each pass through separate delivery tubes 62 into a mixing chamber 65. where it is thoroughly and affinitively mixed by the stirring member 67, and this mixture is A lining that enters the center of the high-speed centrifugal impeller 57 and allows the centrifugal impeller 57 to The lining composition is centrifugally blown against the wall of the sewer pipe, and the lining device 50 As the process progresses, a structural lining of a predetermined thickness is formed.

The hose 63 is gradually slit in the axial direction at the portion 125 and becomes empty. , 126, it transforms into a flattened state, and then, at 127, into each passageway 73 of the guide channel 72 in the flattened state as shown. The anti-tracking shoe 83 ensures alignment with the passageway 73. Ru. As the flattened hose 127 passes through the passageway 73, its closed side edges ( The edge) 128 is cut by the edge cutting structure 80.

At the exit, the cut side edge 12B is guided by a guide 86 (129 in FIG. 10). along the guide 87 and the adjacent delivery tube 62 (shown diametrically). Follow the return passageway between the is pulled back downhole on the exit side by a cable 130 connected to the inch. Ru. It is of course possible to pre-twist the cut side edges through the lining w50. This will be carried out prior to the start of the cleaning operation.

An axially slit empty hose with no side edges is shown at 131, which is shown below. The lining composition remains at the bottom of the water tube 56 and is discharged by the centrifugal impeller 57 by the weight of the skid structure 55 and the lining device 50 until it is covered by the be held down.

Connect the flattened hose 131 to the bottom of the sewer pipe 56 and the drainable line to cover it. The interposition between the lining composition and the lining composition increases the structural strength of the added lining. It is not expected that it will decrease that much. Furthermore, the flattened hose 131 Remaining in place helps smooth the shape of the drain pipe 56, i.e. covers joggle joints or broken joints between adjacent sewer pipes 560 It seems to help.

The advancement of the lining device 50 along the drain 56 is shown in FIGS. 7 and 8. This tractor is assisted by the described driven toothed tractor structure, i.e. The data structure claws forward along the flattened hose 127 of the passageway 73 and this Hose 127 actually serves as a track or rail for this toothed tractor structure. be. It should be understood that this toothed tractor structure is fundamental to the invention. It is not necessary and can be omitted.

The trowel working structure follows behind the lining W50, and it should be noted that , the maximum outer diameter of the conical trowel 122 is larger than the inner diameter of the lined sewer pipe. It's getting slightly bigger.

A flexible thin-walled trowel tube 104 held at section 124 is fitted with a lining device. As the machine 50 moves forward, it is pulled out from the magazine box 113 and flattened. from the closed state to the partially opened state by the spreading spreader guide 118. Gradually open the conical trowel 122 by means of the roller nimbs 117 and 120. and lined sewage under the pressure of a conical trowel 122 Applied against the tube. Place this trowel layer pipe on the wall of the lined sewer pipe. The purpose of the pressure is to remove the surface effect of the applied lining and to remove the surface effect of the lining. The purpose of this process is to smooth the polished surface.

Therefore, the fully lined drain pipe 56 (see Figure 1A) has a flat bottom. Flattened hose 131, having a centrifuged and cured lining 132 , this is what actually becomes the sewer pipe, and there is a trowel layer pipe 1 on its surface. There is 04. The trowel layer tube 104 can simply be left in place if desired. It can also be removed. If you want to remove it, use code 133 or equivalent''# (See FIG. 23) are the inner end of the accordion tube package 112 and the ring 1. 24 and when the lining 132 is cent or cured. Simply pull cord 133 downhole on the inlet side and trowel the layered pipe above-mentioned sewer pipe. 56 lined walls are lined with settable lining material composition 132 (13th (see figure), and the trowel layer pipe 104 is laid along the layer. and the added lining has an inherent tendency to shift from the wall of the sewer pipe. If not, this is usually sufficient. Actually, the lining composition adopted The material is very stable and remains stable between application and full hardening or curing. It has been confirmed that it has retention performance. However, complete curing or Until cure or substantially such process is achieved, the land in any form The sewage pushes the lining material composition 132 and the trowel pipe 104 from the wall of the sewer pipe 56. There is a danger of not knowing whether or not to release it.

Where this is considered possible, tubular plastic tubes or sheaths 1 34 is yonned and inserted into the troweled sewer pipe 56 to trowel layer pipe 1 04 until the lining material composition 132 is completely hardened or cured. Resist slippage caused by groundwater such as. The inserted tube 134 body, preferably the pump 135 and the delivery nozzle! Air supplied by 35A Fully pressurized by Qi.

displacement of sewer pipe lining materials and trowel layer pipes that may be caused by groundwater; or when the trowel layer pipe is removed after troweling is completed, the sewer lining material The use of this pressurized insertion tube to compensate for misalignment is often not necessary. It is something.

When a hose, such as hose 63, is flattened, the closed side edges have a completely flat shape. Edge cutting of the hose is necessary because it will not be compressed in the same way. Closing the hose The bent side edges try to maintain an arcuate or rounded shape, which lifts the edges. Not only that, but also the structural strength of the lining because it is intended to retain air. It is considered undesirable for

However, if a hose such as hose 136 in FIG. Tsuji cutting can be omitted. Such a hose 136 has a flat bottom 137; A cover strip 138 is welded thereto, with the weld providing a flat edge 139. Ru. The two parts 13 are separated when the cover strip 138 is axially slit. 8A and 138B fall onto the flat bottom 137 and lie flat, thus cutting the edge. A flat hose can be obtained without having to perform

This hose 136 can be adapted to the requirements, i.e. its volume capacity is as required. The thickness of the lining can be adapted or adjusted to suit the thickness of the lining.

Furthermore, such hoses can be formed in continuous lengths, and during manufacturing can be filled with the components of the lining composition.

Figures 14 and 15 show three hoses 142 (two filled with resin and one hard). has three delivery tubes 141 used with A lining device 140 is shown. Parts similar to those in the previous embodiment have the same reference numbers. The subscript A is added to the number.

Next, referring to FIGS. 16 to 20, the method and apparatus for lining three hoses Also disclosed is another trowel working structure.

However, in this example, the axially slit empty hose is not left in the drain, and is similar to the cut hose edge of the first previously described embodiment. drawn out.

In this example, there are three hoses, each a length of sewer pipe to be lined. be. Two hoses are filled with resin and a third hose is filled with hardening or curing agent. Filled. These hoses are sealed at each end. to these three hoses The total amount of components of the filled lining composition is predetermined on the walls of the sewer pipe. chosen to give the correct thickness.

The hose is laid along the sewer pipe between the two downholes. they are parallel shape, or can be laid in a triangular shape, or in a concentric hose configuration However, typically three separate hoses are placed close to each other in a parallel configuration. It will be done.

The hose is made of relatively thin plastic material and is suitable for lining sewer pipes. The surface condition is not always perfect, so the sewage hose should be lined. While laying along the length of the pipe, one or more hoses may break and become trapped inside. This can lead to the leakage of accumulated components, which has an adverse effect on the lining of the sewer pipe wall. There is a danger that it will happen.

This hazard can be avoided if the hose is routed along the entire length of the sewer pipe as shown in Figure 17. It seems possible to avoid this if possible. Sewers are generally designated by reference number 150. The downhole is indicated by the reference numeral 151. The hose is 15 2 and transported to the site in a suitable vehicle. drugging or A pull cable 153 is attached to the free end of the prefilled hose and It is passed through a tube and wound up by a drip collection reel 154. hose is indicated by the reference number 155. A hose 155 is drawn through the sewer pipe 150. A temporary barrier 156 is installed in the corner downhole 151 within the sewer pipe 150 before 157 and the drains are flushed with flushing water designated collectively by reference number 157. be swept away. Then, the dragging cable 153 connects the sewer pipe to the handle hose 155. As a result of the presence of water 157, the hose is in a position between the two downholes. It will float. When the hose is in place between the two downholes 151 At this time, temporary barrier 156 is removed to allow water to drain. Now the hose is la This means that the inning operation is in a predetermined position.

Apparatus for carrying out the lining method according to the invention is designated generally by the reference numeral 158. An air vane motor lining machine with a centrifugal spinner head 159 shown in The centrifugal spinner head 159 is provided with a lining composition against the wall of the sewer pipe. projected in a distal direction with a lining generally designated by reference numeral 160. It performs the function of setting. This lining machine has a centrifugal spinner head on the rear side. and move along the sewer pipe between the two downholes (it is a sled structure or wheel A cable wrapped around a capstan indicated generally above by reference numeral 161. Or run along the drain by a wire. Lining machine makes lining composition It has an axial bore 162 for flowing the spinner to the centrifugal spinner head 159. Rai Viewed in the direction of the cutting machine, there is a Lamix head, which is generally defined by 163. As shown, it is equipped with one or more slitting blades 164 and has a slitting blade 164. The cutting blade 164 is preferably shaped like a fish foot and has three hoses 155 passing through it. A vial located within the chamber and connected to the axial bore 162 of the lining machine. A blade 165 is arranged adjacent to the slitting blade 164.

In FIG. 18, a pipe supply device 175 for iron work is also shown, and this is explained below. I will briefly explain.

The iron working structure (Fig. 19) of this embodiment has a rad 176 attached to the iron working pipe. This is a foaming pressure with a diameter larger than the diameter of the sewer pipe being lined. It has a head 177.

The trowel working pipe 178 is connected from the trowel working pipe supply device 175 to the stationary lining device. is fed in a compressed or flattened state through a central hollow shaft and then processed. The passage passing through the guide shape of the industrial pipe attachment head opens into a circular shape, allowing it to be used for work. Addition of pipes.

RAD opens the trowel working pipe and in the open state, RAD 177 and RAD 177 are applied to the foaming pressure. sending between 160 and 160. The iron working pipe 178 is thus attached to the lining 160. Pressed, as mentioned above, removes the solder hardening. Iron work pipe 17B is released and sent to the position between RAD 177 and lining X60 to the foaming pressure. The working guide element 179 achieves a free and unobstructed opening of the trowel working tube. It has a low friction surface to achieve this.

The end of the trowel working pipe, i.e. the last part to be added to the lined sewer wall. The part is equipped with means such as a cord, cable or equivalent 18o, which is suitable for troweling. installed to be removed from the lined wall by troweling with service pipe 178. It is attached.

The end result is a smooth, substantially constant depth lining on the drain pipe.

The configuration shown in FIG. 20 is almost the same as the configuration shown in FIG. In the case of is sent backwards to the additional head. The iron working pipe 181 is locked again, but In this case, it is downhole on the entrance side, and when the line ends there, The working tube is simply stripped from the lined wall with a trowel.

Next, a description will be given with reference to FIGS. 24 to 30.

The drain is indicated by the reference number 200. The lining device has three clans. A delivery tube 201, 202, 203 in the shape of a dog or swan neck is provided. are supported on a carriage (not shown) attached to the sled. pre-filled The hoses (only one shown) are indicated by reference numeral 204.

Each of these hoses has diametrically opposed seams 205.

The hose inlet end of each delivery tube (see Figure 27) has a hose 204 connection. A blade 206 is located diametrically that engages the eye 205; True rectangular path without rotating hose 204 relative to delivery tube Speed it up to make it follow. It should be noted that the leading end of the plaid 206 is It is tapered as shown by 7 to make it easier to enter the hose. Ru.

Immediately aft of the leading end of the delivery tube is a cutting blade 208, which The cutting blade is removably supported on the Ruda 209, and the cutting blade is damaged or dull. Sometimes they can be easily replaced. This cutting blade has a delivery tube. It acts to slit the hose when it is pushed through.

Delivery tube 201.202.203 (see figure 28.29.30) The passage 210 in turn communicates with a passage 210 of the centrifugal lining machine. The bladed blower communicates with the annular mixing chamber 211 immediately behind the impeller 212.

The annular passage 211 opens into a bladed impeller 212 and the blades 2 of the impeller 13 has an extension 214, which, as you may have already understood, is the most For the centable lining composition components that first came together in the annular chamber 211 Acts as a mixing blade.

A bladed impeller 212 is attached to a shaft 215 and connected to an air motor 216. It is therefore driven via gears 217, 218.

The sled structure of the lining device is indicated by 219.

The bladed impeller 212 is effective and keeps the lining material against the sewer pipe. This lining has the above-mentioned tangerine solder effect. This tends to occur and is removed and smoothed out in the manner described above.

Referring again to FIGS. 24-26, advancing through delivery tube 201 The slitted and empty hose 204 initially has a vertical axis 222. It passes between two guide rollers 220 and 221 with Delivery tube 202 The hose to be advanced through passes around the outside of rollers 220 and similarly passes through the delivery hose. The hose 204 that is advanced through the retube 203 rotates around the outside of the roller 221. That's what I mean. Hose 204 now slit, emptied and flattened - together with a lining device which also has a vertical axis and passes through the sewer pipe. Driven by two forces downstream of the rollers 220, 221 in the direction of movement. It passes between rollers 223 and 224. Roller 2 driven by these powers 23, 224 actually form a squeezing roller and are driven by an air motor 226. The air motor 226 has a shaft with a worm 228 and a coupling. The worm 228 is connected to a vertical mounting structure 227 and the worm 228 is The spindle 225 of the axis meshes with the gears 229 and 230 that mesh with each other. It is.

Downstream of the squeeze rollers 223, 224 are rotatable freely about a vertical axis 232. There is a guide roller 231 and the empty and flattened hose 204 is placed on this roller. A rope or wire ( (not shown) in the pull-back direction.
