A kind of well according to claim 8 leaks obstruction method, it is characterized in that: described aggregate is formulated by soya bean, sawdust, rag, sea-tangle.
This well good effect that blocking device and obstruction method thereof bring that leaks is, the sewage produced that leaks can be avoided, exempt eliminating and leak, particularly can prevent from damaging above and below ground facility, the serious consequence that cannot block of leaking for a long time can be avoided, for water hazard prediction explores new method.
Accompanying drawing explanation
Fig. 1 well leaks blocking device schematic diagram.
Detailed description of the invention
Be described with regard to the specific embodiment of the present invention below with reference to Fig. 1.In figure, 1: well pipe, 2: one-level high pressure sluice valve, 3: tee piece, 4: bypass high pressure gate 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: outlet, 14 of leaking: ground.
First the secondary pipe box 10 that diameter is less than well casing is set in well, general secondary pipe box is docked by many pipes to form, original well head on the one-level high pressure sluice valve 2 installed install blowout hookup, described blowout hookup is by tee piece 3 Structure composing, one of them mouth of pipe is connected in the vertical direction consistent with pipe well direction, another one is by-pass port, by-pass port is provided with bypass high pressure gate 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 above, sending down the fishbone materials device 7 is installed above by high pressure valve 8, flange is all adopted to connect between above device, the entrance of high pressure valve 8 utilizes pipeline to be connected with grouting pump 9.
On ground 14 near well, have the outlet 13 of leaking of the water of well, leaking is spilt along leak paths 12 by the breakage in well casing, the well leaked can along with the continuous flowing of leaking, the water yield can be come long-range, along with the impact of flowing water, can strengthen gradually in leak paths 12, outlet 13 of leaking on ground 14 can strengthen too, cavity, ground, long-term leaks, and ground can become vast sea a slice, can harm be brought to the building of surrounding, the facility of above and below ground, need leak stopping as early as possible.
During leak stopping, first, secondary pipe box 10 is entered under in well casing, close secondary high pressure sluice valve 6, by aggregate by soya bean, sawdust, rag, in the aggregate loading sending down the fishbone materials device 7 that sea-tangle etc. are formulated, 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 well casing, aggregate is pressed into from secondary pipe box 10, after aggregate is depressed into secondary catheter end 11, aggregate will leak by entering leak paths 12 between secondary pipe box and former well casing with former well casing, after aggregate enters leak paths, aggregate expands, pile up filling leaking pipe, blocking leak paths 12, after leak paths 12 blocks, adopt cement slurry (general employing volume ratio is the slurry of 1:1), to slip casting between two tube walls, prevent water source from rising between two tube walls, to leak and thoroughly block.
Utilize this well to leak blocking device and obstruction method thereof, the sewage produced that leaks can be avoided, exempt eliminating and to leak construction, reduce ground flowing water, particularly can prevent from damaging above and below ground facility, the serious consequence that cannot block of leaking for a long time can be avoided, for water hazard prediction explores new method.
