Abstract
The utility model discloses an automatic check valve type pressure grouting device, which comprises a pressure grouting pipe body, wherein the end part of the pressure grouting pipe body is connected with a plug, and grout outlet holes are arranged along the axial direction of the wall of the pressure grouting pipe body, and are connected with a grouting check valve. The device can solves the strength reduction defect which is caused by the continuous bottom sediment of bored piles and the underground as well as the concrete disintegration, reduces the continuous subsiding of the bored piles and the underground, extracts the bearing capacity, and saves the foundation construction cost. Moreover, the automatic check valve type pressure grouting device is utilized to eliminate the problems of intercalated mud, abruption and the like of underwater structures with a pressure grouting supplement method, so the underwater structures can be repeatedly used, an the cost is reduced.
Description
Technical field
The utility model belongs to Foundation Design and based process slip casing by pressure strengthening construction device, is specifically related to the automatic check valve-type grouting device that underground grout outlet place is reinforced in Foundation Design and based process slip casing by pressure.
Background technology
In bored pile and the construction of diaphragm wall process, because of the construction technology problem, there is heavy quarrel inevitably in the bottom; In addition, when carrying out the underwater concrete perfusion, it is thin because the concrete perfusion conduit is long, and be full of mud in the pipe, pile concrete drop in conduit is big, certainly will be subjected to the influence of mud in the conduit and cause concrete disintegration, produce " empty point ", " doing quarrel stone " etc. in the stake bottom, reduce its intensity.The existence of all these problems being subjected under the vertical load effect excessive sedimentation taking place, has reduced the bearing capacity of bored pile and diaphragm wall, increases the foundation construction expense.In addition, in the underwater concrete filling process of bored pile, diaphragm wall or other underwater structures, quality accidents such as folder mud, tomography taking place through regular meeting, causes scrapping of underwater structure.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic check valve-type pressure grouting device for overall that is connected the Grouting Pipe lower end, to address the above problem.
The technical solution of the utility model is: automatic check valve-type pressure grouting device for overall, and it comprises the slip casing by pressure body, and the end of slip casing by pressure body connects plug, and the tube wall of slip casing by pressure body offers slurry outlet vertically, and slurry outlet is connected with out slurry check valve.
Describedly go out slurry check valve and comprise the type of the carving stopple that is connected with slurry outlet, the tube wall of slip casing by pressure body adheres to rubber sleeve outward, and rubber sleeve compresses carves the type stopple.
The tube wall of the slip casing by pressure body at described rubber sleeve two ends is provided with the constraint mud retaining ring.
This device taper plug is convenient to and will be inserted in the heavy quarrel with automatic check valve-type pressure grouting device for overall, mud retaining ring is to protect rubber sleeve in the heavy quarrel process of check valve-type slip casing by pressure device insertion automatically, the automatic check valve-type slip casing by pressure device core texture of the common formation of injected hole, wedge shape stopple and rubber sleeve, during slip casting, when the high pressure cement slurries back down the wedge shape stopple from interior pipe, the two ends by rubber sleeve are injected in the heavy quarrel on stratum; After stopping slip casting, utilize the elastic reaction of rubber sleeve, the wedge shape stopple is pushed back in the injected hole, the sealing injected hole can not be back in the grouting pipeline high pressure cement slurries in the heavy quarrel that is injected into the stratum, plays one way valve and ends the slurry effect, guarantees slip casting effect.Handle heavy quarrel in bored pile and underground continuous bottom and concrete disintegration and cause intensity to reduce, reduce bored pile and underground continuous sedimentation, propose its bearing capacity, save the foundation construction expense.And, utilize this device, by slip casing by pressure reinforcement means, problems such as the folder mud of elimination underwater structure and tomography can be utilized it again, reduce the loss.
Description of drawings
The automatic check valve-type pressure grouting device for overall of Fig. 1 user mode schematic diagram.
The automatic check valve-type pressure grouting device for overall of Fig. 2 structural representation.
The specific embodiment
As shown in Figure 1, automatic check valve-type pressure grouting device for overall is used for slip casting, the end of Grouting Pipe 2 connects (weld or be threaded) automatic check valve-type pressure grouting device for overall 1 of the present utility model, the high-pressure injection pump 3 liquid slurry that pressure injection cement paste or other can consolidated earth masses in Grouting Pipe 2.4-borehole wall or wall section cell wall; 5-drilled pile or diaphragm wall reinforcing cage.
As shown in Figure 2, check valve-type pressure grouting device for overall 1 comprises slip casing by pressure body 1.1 automatically, and slip casing by pressure body 1.1 ends connect plug 1.2, and plug is taper.Slip casing by pressure body 1.1 upper edge tube walls offer slurry outlet 1.3, the type of the carving stopple 1.4 that slurry outlet 1.3 connects, and the tube wall of slip casing by pressure body adheres to rubber sleeve 1.5 outward, and rubber sleeve 1.5 compresses carves type stopple 1.4.The tube wall of the slip casing by pressure body at rubber sleeve 1.5 two ends is provided with constraint mud retaining ring 1.6.Slurry outlet 1.3 is to carve the type hole, and carves type stopple 1.4 and matches.
Claims (3)
1. automatic check valve-type pressure grouting device for overall, it comprises the slip casing by pressure body, and the end of slip casing by pressure body connects plug, it is characterized in that the tube wall of slip casing by pressure body offers slurry outlet vertically, and slurry outlet is connected with out slurry check valve.
2. automatic according to claim 1 check valve-type pressure grouting device for overall, it is characterized in that describedly going out slurry check valve and comprising the type of the carving stopple that is connected with slurry outlet, the tube wall of slip casing by pressure body adheres to rubber sleeve outward, and rubber sleeve compresses carves the type stopple, and slurry outlet is to carve the type hole.
