Abstract
The utility model discloses a hole-sealing grouting plug; the periphery of a metal inner pipe is sheathed with a pressure-resistant rubber hose; the metal inner pipe is connected with the pressure-resistant rubber hose by an upper sealing head and a lower sealing head to achieve the air seal; a cavity is formed between the rubber hose and the metal inner pipe; the cavity is communicated with an air feeding pipe; the metal inner pipe is internally provided with a grout feeding pipe; the upper end of the metal inner pipe is connected with the grout feeding pipe, and the lower end thereof stretches out of the metal inner pipe; the upper sealing head is provided with a grout returning pipe and is communicated with the cavity between the metal inner pipe and the grout feeding pipe; the metal inner pipe is connected with the rubber hose, the upper sealing head and the lower sealing head compactly and firmly, thus being incapable of appearing air leakage phenomenon of the rubber hose; and the inner wall of a clamp hoop and the outer walls of the upper sealing head and the lower sealing head are provided with a tightly-clamping and concave-convex connecting structure, thus saving the trouble of the threaded connection, and simultaneously, overcoming the shortcomings of the unevenness of the whole hole-sealing grouting plug and difficult taking out after use.
Description
Technical field
The utility model relates to construction of hydropower plant and mining technique field, relates in particular to sealing of hole slip casting plug.
Background technology
At present, during most of water power, hydraulic engineering were leaked at the processing dam foundation, the infiltration of basic contact zones is constructed, need be in the milk (as cement paste) in work progress, all used sealing of hole slip casting to fill in the sealing of capable aperture; Filling in row in field of mining also extensive use sealing of hole slip casting send oxygen, send water.Present sealing of hole slip casting plug generally is that the metal inner pipe two ends are provided with end socket, inside is provided with inlet pipe, return pipe, the metal inner pipe outside is provided with rubber tube, and the two ends of rubber tube are connected with metal inner pipe by end socket, and the time spent is put into the suitable degree of depth with sealing of hole slip casting plug, in rubber tube, pour gases at high pressure, rubber sleeve is expanded, be squeezed in the hole, carry out injection hole sealing then or send water, send operation such as oxygen, treat behind the complete operation gas in the rubber tube to be emitted, can take out sealing of hole slip casting plug.Because end socket and clip inwall all have chucking bindiny mechanism, end socket also adopts part to be threaded with clip, can form a projection " pimple " at the screw thread place during clip chucking, this structure not only bothers when producing, and in use mud can be accumulated on this projection, condense gradually, the situation that sealing of hole slip casting plug can not normally take out often takes place.
Summary of the invention
Be the deficiency that solves present sealing of hole slip casting plug production trouble, difficulty is taken out in the often appearance of finishing using, it is a kind of simple in structure that the utility model provides, processing, and the sealing of hole slip casting plug of taking-up easy to use easily.
For realizing above-mentioned technical purpose, the utility model is achieved through the following technical solutions:
At the peripheral socket pressure-resistant rubber hose of metal inner pipe, metal inner pipe is connected by upper and lower end socket with rubber tube and reaches hermetic seal, forms cavity between rubber tube and metal inner pipe, and this cavity communicates with air pipe; Be provided with inlet pipe in metal inner pipe, its upper end links to each other with inlet pipe, and metal inner pipe is stretched out in the lower end; Upper cover is provided with a return pipe, is communicated with the cavity between metal inner pipe and the inlet pipe; During use the sealing of hole packer is put into predetermined position, hole, in air pipe, inject gases at high pressure, rubber tube expands and is adjacent to and seals the duct, toward inlet pipe and grout pipe the purpose medium is sent into the duct, after treating that the purpose medium dashes the space of full sealing of hole packer bottom, remaining media will flow out by return pipe, realize sealing of hole grouting, send water, send operation such as oxygen.Behind the end of operation, the gases at high pressure in the rubber tube are discharged, take out the sealing of hole packer and get final product.
Because in aforesaid operations, to be full of gases at high pressure between rubber tube and the metal inner pipe, last low head with sealing is arranged on rubber tube is connected, firmly wait technical requirements, the outer wall of last low head is provided with chucking bindiny mechanism, and be provided with an annular groove, corresponding chucking bindiny mechanism and the annular protrusion of being provided with of clip inwall, clip tightly is locked on the low head by the two ends of big pressure with rubber tube, annular protrusion on the clip inwall is clamp-oned the rubber tube wall in the annular groove on the end socket outer wall, realize sealing between end socket and the rubber tube, the firmly technical requirements that connects, after above-mentioned described clip compresses lock by height, end socket, rubber tube, and the clip external surface keeps equal, and it is one smoothly cylindric making sealing of hole slip casting plug integral body.
The utility model is compared with present technology has following beneficial effect: metal inner pipe is connected closely with rubber tube, last low head and firmly, the generation of rubber tube gas leak phenomenon can occur; The clip inwall reaches the outer wall of going up low head and is provided with chucking and concave-convex connection structure, saves the trouble that is threaded, and has also overcome the whole out-of-flatness of sealing of hole slip casting plug simultaneously, uses the back to be difficult for the deficiency of taking out.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the enlarged drawing at A place in the utility model.
In the accompanying drawing, 1, low head, 2, clip, 3, rubber tube, 4, metal inner pipe, 5, upper cover, 6, air pipe, 7, inlet pipe, 8, return pipe, 9, grout pipe.
The specific embodiment
Referring to accompanying drawing 1, metal inner pipe 4 two ends connect by upper cover 5 and low head 1, and grout pipe 9 is positioned at metal inner pipe 4 inside, and an end links to each other with inlet pipe 7, and the other end stretches out metal inner pipe 4, and inlet pipe 7 reaches sealing of hole slip casting portion beyond the Great Wall on upper cover 5; Also be extended with return pipe 8 and air pipe 6 on the upper cover 5 simultaneously, the space that return pipe 8 is communicated with between metal inner pipe 4 and the grout pipe 9; Metal inner pipe 4 peripheries covers rubber sleeve 3, rubber tube 3 two ends are fixing by upper cover 5, low head 1, guarantee the tightness in the space between metal inner pipe 4 and the rubber tube 3, and above-mentioned have bubble-tight space and be communicated with air pipe 6; During use sealing of hole slip casting plug put into expection position, hole, in injection well, pour gases at high pressure, rubber tube 3 expands and is adjacent to hole wall, at this moment, sealing of hole slip casting plug is fixed on predetermined position, hole, send into the purpose medium in inlet pipe 7, by grout pipe 9 the purpose medium is filled into the lower end of sealing of hole slip casting plug, filling with the remaining purpose medium in back will be by return pipe 8 discharge.
Referring to accompanying drawing 2, upper cover 6 and low head 1 and the sealing of rubber tube 3 connection requests, firmly, therefore the junction periphery at rubber tube 3 two ends is provided with clip 2, on seal 6 and low head 1 and the rubber tube 3 position radius of a circle of pegging graft less, and be provided with chucking bindiny mechanism and an annular groove that caves inward, clip 2 inwalls are provided with chucking bindiny mechanism and an annular protrusion equally, clip 2 is pressed on the two ends of rubber tube 3 on the low head, annular protrusion on clip 2 inwalls is pressed into rubber tube 3 in the annular groove of upper cover 6 and low head 1, when playing sealing, also strengthened the fastness that both connect.
