Description

A spliced ground dewatering pipeline

Technical Field

The invention relates to the technical field of electric dewatering pipelines, and in particular to a spliced formation dewatering pipeline.

Background technique

With the development of the economy, rail transit construction in various cities, especially in southern cities, precipitation is a necessary project at the beginning of many projects. In the past few years, many construction teams cut water holes manually to achieve the role of precipitation pipes. However, with the requirements of environmental protection and the improvement of construction technology, standardized precipitation pipes are needed. For example, the commonly used caliber of Shenzhen Metro is between 400-800, which meets the local hydrological conditions and can quickly carry out precipitation construction and reduce costs. Since subway precipitation is very necessary in construction, different geological layers have different geological components in the stratum precipitation link, and may also be accompanied by impurities. In the process of drainage, silt and impurities will inevitably be sucked into the vacuum precipitation pipe. After a long period of precipitation operation, the precipitation pipe will be blocked, affecting the subsequent precipitation effect. A domestic patent with a publication number of CN114875941B discloses a high-efficiency dewatering system for sand-containing and water-rich strata, which mentions a dewatering pipeline, including an outer casing, an inner casing and a pump body. The outer casing is used to be vertically inserted into a foundation pit. The length of the inner casing is less than that of the outer casing. The inner casing is used to be inserted into the outer casing. The pump body is arranged in the inner casing. A pipeline is arranged on the pump body. The pipeline extends to the outside of the outer casing. The pump body is used to pump water in the inner casing out of the foundation pit, which has the effect of reducing the damage to the pump body during dewatering operation. It is designed with inner and outer pipes. When groundwater in the soil seeps into the inner casing, the groundwater accumulates between the outer casing and the inner casing, so that the sand and gravel in the groundwater can settle on the outside of the inner casing. When the groundwater level accumulated between the outer casing and the inner casing rises to the same level as the inner casing, the groundwater can flow into the inner casing and be discharged through the pump body. The groundwater flowing into the inner casing has smaller sand and gravel, and the loss to the pump body is smaller, but it can only achieve a coarse filtration effect, and cannot adapt to geological environments such as those with finer sand or complex impurities.

Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

Embodiment 1

As shown in Figures 1 to 7, a spliced formation dewatering pipeline comprises a plurality of dewatering pipe sections 1 and a quick-connect assembly kit 3 for connecting the plurality of dewatering pipe sections 1 at two adjacent ends. The dewatering pipe section 1 and the quick-connect assembly kit 3 are connected via an end water filter sleeve 2. An end water filter plate 4 is provided at the connection between the end water filter sleeve 2 and the end of the dewatering pipe section 1. An end water filter hole 5 is provided on the end water filter plate 4. The quick-connect assembly kit 3 comprises a hinged first quick-connect ring 6 and a second quick-connect ring 7, and a second filter plate 8 arranged in a cavity formed by the first quick-connect ring 6 and the second quick-connect ring 7. One ends of the first quick-connect ring 6 and the second quick-connect ring 7 are hinged to each other, and a first filter plate 9 is provided on the first quick-connect ring 6.

During assembly, the end water filter sleeve 2 is sleeved on the end of the multi-section downpipe section 1, and the two ends of the multiple sets of quick-connect assembly kits 3 are respectively sleeved on the end water filter sleeve 2 on the same side, a first connecting plate is provided on the first quick-connect ring 6, and a second connecting plate is provided on the second quick-connect ring 7. The first connecting plate and the second connecting plate are connected by bolts.

Design a multi-section downpipe section 1 and a quick-connect assembly kit 3 for connecting the downpipe sections 1 at both ends, assemble on the matching end filter sleeve 2, and achieve a multi-section filtering effect through free multi-section splicing. At the same time, it has the ability to be disassembled and replaced for cleaning. At the same time, because modular splicing is achieved, the requirements for the length of the production pipeline and transportation are reduced. At the same time, modular splicing facilitates the disassembly and replacement of the pipeline, which reduces the cost of replacing the entire pipeline for users; for manufacturers, first, the price of the whole pipe with the same specification and length is higher, and second, the production difficulty and transportation costs are reduced.

A positioning arrow 19 is recessed on the end water filter sleeve 2, a first water filter hole 10 is provided on the first filter plate 9, and a second water filter hole 11 is provided on the second filter plate 8. The apertures of the first water filter hole 10, the second water filter hole 11, and the end water filter hole 5 are consistent. The first water filter hole 10, the second water filter hole 11, and the end water filter hole 5 cooperate with each other to filter impurities brought in during vacuum precipitation, reduce the impact of impurities and sludge on precipitation work, block the impact on the drainage pipe section during vacuum pumping, and extend the life cycle of the drainage pipe.

The first quick-connect ring 6 and the second quick-connect ring 7 are provided with an indicator scale (not shown in the figure) on their outer peripheries, and the indicator scale is arranged around the indicator scale. By positioning the indicator arrow 19 to point to the indicator scale and reading the corresponding value, the size of the passing area is obtained, and the adjustment is made in turn according to the actual situation to ensure the adjustment effect.

A rack ring 12 is provided on the end water filter sleeve 2, and latch teeth 13 are provided at the upper and lower ends of the inner side of the first quick-connect ring 6, and the rack ring 12 and the latch teeth 13 are engaged with each other. The rack ring 12 and the latch teeth 13 are engaged with each other, and only one-way rotation is allowed, and the reverse rotation is impossible, which ensures that after being adjusted to a certain position, the quick-connect assembly kit 3 will not rotate relative to the end water filter sleeve 2 and the downflow pipe section 1, and during the dewatering work, the end water filter sleeve and the quick-connect assembly kit are stably connected, and because the end water filter sleeve and the downflow pipe section are in interference connection, the downflow pipe section and the quick-connect assembly kit are stably connected.

The first quick-connect ring 6 is provided with a first sealing strip 14 at the upper end of the rack ring 12, and the second quick-connect ring 7 is provided with a second sealing strip 15 protruding corresponding to the first sealing strip 14. When both ends of the first quick-connect ring 6 and the second quick-connect ring 7 are connected to each other, the first sealing strip 14 and the second sealing strip 15 are connected to form a sealing ring.

The first filter plate 9 is fixedly connected in the inner cavity of the first quick-connect ring 6, and the fixing ensures that the position of the first filter plate 9 relative to the first quick-connect ring 6 does not change, thereby ensuring the adjustment effect.

The outer surface of the second filter plate 8 is provided with outwardly protruding plugs 16 in a row, the first quick-connect ring 6 is provided with a first connecting groove 17a corresponding to the plugs 16, and the second quick-connect ring 7 is provided with a second connecting groove 17b corresponding to the plugs 16, and the plugs 16 are connected to the first connecting groove 17a or the second connecting groove 17b.

The cross section where one end of the first connection groove 17a is located is in the same plane as the inner cavity formed by the first filter plate 9 and the second quick-connect ring 7, and the cross section where one end of the second connection groove 17b is located is in the same plane as the inner cavity formed by the first filter plate 9 and the second quick-connect ring 7; the cross section where the other end of the first connection groove 17a is located is close to the end of the first quick-connect ring 6 on the same side, and the cross section where the other end of the second connection groove 17b is located is close to the end of the second quick-connect ring 7 on the same side;

A spring 18 is disposed in each of the first connection groove 17 a and the second connection groove 17 b . One end of the spring 18 is connected to the insert 16 , and the other end of the spring 18 is connected to the end of the first connection groove 17 a or the second connection groove 17 b close to the first filter plate 9 .

Furthermore, during assembly, the connection direction of the spring 18 and the insert 16 is the vacuum precipitation pumping direction. During vacuum pumping, the impact force of water is huge. If the direction is reversed, the elastic force of the spring may not be able to resist the impact of water, so that the second filter plate 8 cannot fit tightly with the end water filter plate 4, resulting in a gap, and thus the water filtration adjustment formed by adjusting the relative positions of the two through their respective filter holes cannot be achieved.

The first quick-connect ring 6 is further provided with a disassembly recessed ring groove 21 at one end thereof corresponding to the first connection groove 17a away from the first filter plate 9, and the inner diameter of the disassembly recessed ring groove 21 is greater than or equal to the maximum diameter of the rack ring 12 for easy disassembly.

The specific operations when using are as follows:

First, sleeve the end water filter sleeve 2 on the end of the downflow pipe section 1. The two are interference fit and the connection is stable. Then, open the first quick connect ring 6 and the second quick connect ring 7, and insert the downflow pipe section 1 with the sleeved end water filter sleeve 2. While inserting, align it to the reference position through the positioning indicator arrow 19 and the indicator scale. The reference position is generally when the first water filter hole 10 and the end water filter hole 5 overlap with each other, and the second water filter hole 11 and the end water filter hole 5 overlap with each other. Then, screw the first quick connect ring 6 and the second quick connect ring 7 together through bolts. When the filter hole size needs to be adjusted, the adjustment is completed by unidirectionally rotating the quick connect assembly kit 3 or the downflow pipe section 1.

When disassembly is required, the quick-connect assembly kit 3 is pushed in the direction of water pumping. Due to the presence of the second filter plate 8 that can slide in the inner cavity of the quick-connect assembly kit 3, the entire quick-connect assembly kit 3 moves toward the downcomer pipe section 1 in the direction of water pumping, and the rack ring 12 on the water filter sleeve 2 sleeved on the downcomer pipe section 1 is separated from the latch tooth 13. Then, the bolts are removed to separate one end of the first quick-connect ring 6 and the second quick-connect ring 7, that is, the quick-connect assembly kit 3 is opened, and then the quick-connect assembly kit 3 is removed, and the quick-connect assembly kit 3 and the water filter sleeve 2 are cleaned.
