Abstract
The invention belongs to the technical field of designing of water stopping pinheads and discloses a high-pressure water stopping pinhead which comprises a grouting hole, an injection nozzle, a hollow bolt and a sealed expansion sleeve. The injection nozzle is arranged at one end of the grouting hole, a screw of the bolt is connected with the inner wall of the grouting hole in a tightening manner, the expansion sleeve is fixed on the outer wall of the grouting hole in a sleeved manner, and a one-way stop valve is arranged in the injection nozzle. The high-pressure water stopping pinhead is characterized in that one or multiple collapsing pieces and a one-way sealed discharging hole are arranged in the grouting hole, the grouting hole is communicated with the expansion sleeve through the one-way sealed discharging hole, and the expansion sleeve is made by rubber. The high-pressure water stopping pinhead is reasonable and simple in structure and easy to produce and manufacture, close fitting between the water stopping pinhead and a drilling hole is guaranteed, and quality and performance of grouting and leakage stopping are improved effectively.
Description
Technical field
The present invention relates to a kind of Water slop injector, especially a kind ofly pour into the high pressure Water slop injector that blowing agent uses, belong to Water slop injector design field.
Background technology
Subway, tunnel, building construction, treatment tank etc. leakage of buildings, often bring very large potential safety hazard, concrete underwater portion, once produce underwater concrete defect, to cause leakage of buildings, for avoiding seepage, now generally in the boring of the place of seepage, blowing agent is poured into from hole to wall inner side, the characteristic of utilizing blowing agent to be frozen into foaming shape can play the effect of waterproof leakproof.In the occasion of the chemical grouts such as filling concrete polyurethane and epoxy resin, adopt high pressure chemistry grouting leak-stopping technology, carry out the construction of high pressure chemistry grouting leak-stopping, often all be unable to do without high pressure Water slop injector, the lasting high pressure that utilizes grouting machine to produce, chemical feed liquid is filled in the gap of concrete inside, and the water in seam is squeezed away completely, gap is filled completely completely, reach the object of sealing, but existing Water slop injector poor sealing performance in hole, brings impact to grouting leak-stopping capability and performance.
Summary of the invention
The present invention is exactly for above-mentioned prior art problem, and a kind of simple, easy to use, high high pressure Water slop injector of perfusion sealing performance rational in infrastructure is provided.
The present invention realizes like this, high pressure Water slop injector, comprise the bolt of injected hole, coupler, hollow, the expansion sleeve of sealing, coupler is arranged on one end of injected hole, and the screw rod of bolt screws and is connected with injected hole inwall, and expansion sleeve is nested with and is fixed on injected hole outer wall, in coupler, be provided with unidirectional stop valve, it is characterized in that, be provided with disintegrating tablet, one-way sealing discharge opening in injected hole, injected hole connects by one-way sealing discharge opening and expansion sleeve.
Described expansion sleeve is the expansion sleeve that elastomeric material is made.
Described disintegrating tablet is one or more.
The present invention is rational in infrastructure simple, manufacture easily, by the present invention, in actual use, high pressure Water slop injector is put into the boring of building body, outside material feeding equipment is pressurizeed and is injected slurry by material injection nozzle, due to stopping of disintegrating tablet, slurry enters expansion sleeve by one-way sealing discharge opening, expansion sleeve starts to expand, the boring of expansion sleeve outer wall and building body fits tightly sealing, in the time that the boring of expansion sleeve and building body fits tightly and cannot expand again, slurry cannot enter expansion sleeve by one-way sealing discharge opening again, slurry pushes to disintegrating tablet, disintegrating tablet is racked by slurry, slurry is expelled in building body smoothly, implement leak stopping effect.In the present invention, injected hole is to connect by one-way sealing discharge opening and expansion sleeve, therefore, the part that slurry enters after expansion sleeve by one-way sealing discharge opening cannot return in injected hole, press even if stop note, and slurry also can not flow backwards, and expansion sleeve keeps swelling state, the tight moment gluing, sealing of boring of having guaranteed expansion sleeve outer wall and building body, according to the demand of disintegrating tablet compressive resistance, disintegrating tablet of the present invention can be set to one or more.
Ensure fitting tightly of Water slop injector and boring by the present invention, effectively improved quality and the performance of grouting leak-stopping.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1 injected hole, 2 couplers, 3 bolts, 4 expansion sleeves, 5 disintegrating tablets, 6 one-way sealing discharge openings.
