Step 3: regulating magnet makes each electromagnet in anti-collapse hole standard knot with identical magnetism, keeps its mutually exclusive,
The repulsive force between each electromagnet is adjusted, makes each electromagnet that the steel wire of flexible steel wire net cylinder body be driven to squeeze borehole wall, pressure
Real borehole wall realizes anti-collapse hole.
In step 2, when anti-collapse hole standard knot is more piece, into drilling, sunk type is sequentially loaded into the anti-collapse hole standard of more piece
Section connects the electromagnet between adjacent anti-collapse hole standard knot in sinking, and the support for reconnecting adjacent anti-collapse hole standard knot is hollow
Keel, until the anti-collapse hole standard knot of bottom sinks to drilling hole bottom.
The anti-collapse aperture apparatus of electromagnetism provided by the invention and method have electromagnet by installing on flexible steel wire net cylinder body
Support hollow joist form anti-collapse hole standard knot, between electromagnet and electromagnet repulsive interaction drive flexible steel wire net cylinder
Body squeezes borehole wall, and then is compacted borehole wall and realizes anti-collapse hole；Can solve casing or mud off bring it is heavy, at
The problem that this height, effect are poor, limitation is big makes flexible steel wire net barrel support drill using the repulsive interaction between electromagnet
And it is compacted hole wall, it is effectively prevent the generation of the drilling collapse hole phenomenon such as bored concrete pile drilling and armature boring, can be widely applied to reality
In borehole engineering.Anti- collapse hole standard knot can take out from drilling, reuse, greatly reduce construction cost.
