Description
Technical field
The present invention relates to a kind of deep well borehole wall orientation plugging device and method for blocking thereof, belong to deep well borehole wall damage revamping technical field.
Background technology
Presently used blocking method is to use cement leak stopping.Carry out mending pipe with the pipe that caliber is less, specifically mended borehole wall position by entering under less pipe, top connects anti-Threaded Connector Coupling, jointed rod, mends apart windings palm fibre skin, Thallus Laminariae (Thallus Eckloniae) at the 1m of pipe bottom, and continuous injected clear water, making Thallus Laminariae (Thallus Eckloniae) expand, cement mortar passes through drilling rod, anti-Threaded Connector Coupling, injects in the annular gap of wall casing and benefit pipe, after theing cement solidifies, drilling rod, anti-Threaded Connector Coupling together return out well head.The method cement setting time is long, relatively costly, if again there is the damaged bad process of tube wall.
Summary of the invention
For solving the technical problem that prior art exists, the invention provides a kind of simple to operate, use orientation slip casting closure, improve the globality of the borehole wall, plugging effect more preferable deep well borehole wall orientation plugging device and method for blocking thereof.
For achieving the above object, the technical solution adopted in the present invention is that the deep well borehole wall orients plugging device, including housing, described case top is provided with suspension rod, is provided with double-action hydraulic jack, the piston rod of described double-action hydraulic jack is provided with support backing plate in housing, support and be provided with step through-hole on backing plate, being provided with sealing ring on described step through-hole, be provided with Grouting Pipe in described step through-hole, described Grouting Pipe is connected with grouting pump by connecting flexible pipe.
Preferably, described sealing ring is mainly made up of annular portion and tapered portion, and described arc sections exceeds the surface supporting backing plate.
Preferably, the outside of described sealing ring is additionally provided with outer seal ring.
Preferably, the top of described housing is additionally provided with master control system, and described suspension rod is provided with image collecting device, and described image collecting device is connected with master control system, and described master control system is connected with host computer by cable.
Preferably, described image collector is set to high-definition camera.
A kind of deep well borehole wall orientation method for blocking, follows the steps below,
A, first orientation plugging device is placed in deep well to bore position；
B, by image collecting device observe bore position, to orientation plugging device be finely adjusted, make Grouting Pipe alignment boring；
C, by control double-action hydraulic jack, make slowly to stretch out away from the support backing plate of boring side, be supported on deep well well bore wall, after the fully aligned boring of Grouting Pipe, the support backing plate of Grouting Pipe side stretches out and is supported on deep well well bore wall, and carries out compressing sealing；
D, startup grouting pump, make slurry filling arrive in boring, and pressure reaches 1-1.5MPA, stops slip casting, block complete after continuing 10min.
Compared with prior art, the present invention has following technical effect that the closure targeted of the present invention is higher, and the material of injection can solidify faster, and the time of shortening reduces cost；Change the stress of the borehole wall, adding the tension of the borehole wall, comprcssive strength, after effective prevention borehole wall compression damage and wall, the pore water of various pollutions in the soil body, rock mass, interstitial water, crevice water enter well, it is ensured that the effect of closure slip casting, technique is simple, it is simple to operation.
