Abstract

A well water leakage blocking device, belonging to the water source leak stopping field, comprises a one-grade high pressure gate valve connected with a well pipe. The one-grade high pressure gate valve is equipped with a blowout prevention device, a second-grade high pressure gate valve, a low aggregate device, a high pressure valve and a grouting pump. A second-grade sleeve pipe is disposed inside the well pipe, so sewage caused by water leakage is prevented, water leakage is avoided and eliminated and ground water flowing is minimized. In particular, overground and underground facilities are prevented from being damaged to overcome severe problems that blocking cannot be achieved due to long-term water leakage.

Description

A kind of well blocking device that leaks

Technical field

The utility model relates to a kind of blocking device that leaks, and particularly a kind of well blocking device that leaks, belongs to leak stopping field, water source.

Background technology

In coalfield, around the water supply well of factories and miness, on well head floor, there will be a small amount of water outlet phenomenon, this situation is often because be subject to the pressure in bottom deformation around or certain plot, make Water Well tracheal rupture, or because of well long service time, caused leaking that the corrosion of well well casing occurs that small gap causes, this leaking at short notice, can bring the inconvenience of the aspects such as maintenance operation, also can cause that ground leaks can cause ground flowing water, need to utilize special-purpose drainage pump to get rid of leaks, particularly in coalfield, if produced, leak, can be penetrated into down-hole, can strengthen effluent cost like this, from the point of long-term development, can cause the well casing increasing of breaking, cause well inside to cave in, polluted source, stop up the danger such as well pipeline, severe one can be to equipment Foundations around, impact is brought in building foundation, in order to prevent trouble before it happens, the obstruction that need to leak, prevent from leading to large problem.

General obstruction method is to take chemical grouting mode to stop up, and in well head boring around, injects slurry and stops up.But, tending to because the water velocity of leaking is very fast, chemical sizwe is complete reaction not, and the current that will be leaked are gone out, and cause the failure of chemical mode obstruction method.How solving this seepy question, is the problem that water utilities worker is comparatively concerned about.

Summary of the invention

For well, leak, utilize the chemical sizwe cannot blockage problem, the utility model provides a kind of well blocking device that leaks, and its objective is thorough obstruction well seepy question.

The technical scheme that the utility model is taked is: a kind of well blocking device that leaks, be included in the one-level high pressure sluice valve connecting on well casing, on described one-level high pressure valve, be disposed with blowout hookup, secondary high pressure sluice valve, sending down the fishbone materials device, high pressure valve, grouting pump, in described well casing, be provided with secondary sleeve pipe, described blowout hookup has adopted a tee piece, one of them direction is linearly connected with well casing, another one direction is bypass, in described bypass, connecting bypass high pressure sluice valve, described secondary high pressure sluice valve be connected to well casing direction linearly on, described secondary high pressure sluice valve is connected on blowout hookup by a pipe nipple, described sending down the fishbone materials device is connected in the vertical direction on secondary gate valve, described high pressure valve is arranged in the vertical direction on sending down the fishbone materials device, the slurry pipe of described grouting pump is connected in the top of high pressure valve mutually, the degree of depth of described secondary sleeve pipe is less than the degree of depth of well casing.

This well good effect that blocking device brings that leaks is, can avoid the sewage that leaks and produce, exempt getting rid of and leak, particularly can prevent from damaging above and below ground facility, can avoid the serious consequence of leaking for a long time and cannot stop up, for water damage is administered the new method of having explored.

Accompanying drawing explanation

Fig. 1 well blocking device schematic diagram that leaks.

The specific embodiment

Below with reference to Fig. 1, with regard to the specific embodiment of the present invention, describe.In figure, 1: well pipe, 2: one-level high pressure sluice valve, 3: tee piece, 4: bypass high pressure sluice valve, 5: pipe nipple, 6: secondary high pressure sluice valve, 7: sending down the fishbone materials device, 8: high pressure valve, 9: grouting pump, 10: secondary pipe box, 11: secondary catheter end, 12: leak paths, 13: the outlet, 14 of leaking: ground.

First in well, the secondary pipe box 10 that diameter is less than well casing is set, general secondary pipe box is to be formed by many pipe docking, on the one-level high pressure sluice valve 2 of installing, blowout hookup is installed on original well head, described blowout hookup is to consist of tee piece 3 structures, one of them mouth of pipe is connected in the vertical direction consistent with pipe well direction, another one is by-pass port, on by-pass port, be provided with bypass high pressure sluice valve 4, in the vertical direction of blowout hookup, be assembled with a pipe nipple 5, on pipe nipple 5, secondary high pressure sluice valve 6 is installed, sending down the fishbone materials device 7 is installed in the above, sending down the fishbone materials device 7 is installed above by high pressure valve 8, more than between device, all adopt flange to connect, the entrance of high pressure valve 8 utilizes pipeline to be connected with grouting pump 9.

On near the ground 14 well, there is the outlet 13 of leaking of the water of well, leaking is to spill along leak paths 12 by the breakage in well casing, the well leaking can be along with constantly flowing of leaking, the water yield can be come long-range, and along with the impact of flowing water, the interior meeting of leak paths 12 strengthens gradually, the outlet 13 of leaking on ground 14 can strengthen too, cavity, ground, long-term leaks, and ground can become vast sea a slice, to building around, the facility of above and below ground, can bring harm, need leak stopping as early as possible.

During leak stopping, first, in well casing, be lowered to secondary pipe box 10, close secondary high pressure sluice valve 6, by aggregate by soya bean, sawdust, rag, the formulated aggregate such as sea-tangle packs in sending down the fishbone materials device 7, then, open secondary high pressure sluice valve 6, utilize high-pressure injection pump 9, high pressure valve 8, by high speed and high pressure, in from secondary pipe box 10 to well casing, be pressed into aggregate, when aggregate is depressed into after secondary catheter end 11, aggregate will leak by entering leak paths 12 between secondary pipe box and former well casing with former well casing, when aggregate enters after leak paths, aggregate expands, pile up filling leaking pipe, stop up leak paths 12, after leak paths 12 is stopped up, adopt cement slurry (generally adopting volume ratio is the slurry of 1:1), to slip casting between two tube walls, prevent that water source from rising between two tube walls, to leak and thoroughly stop up.

Utilize this well leak blocking device and obstruction method thereof, can avoid the sewage that leaks and produce, exempt and get rid of the construction of leaking, reduce ground flowing water, particularly can prevent from damaging above and below ground facility, can avoid the serious consequence of leaking for a long time and cannot stop up, for water damage is administered the new method of having explored.
