Practice proves that the method can ensure the safety and stability of hole washing and the general application in the in-situ leaching mine, and can also be applied to other industries.

2. Technical scheme

An inground infusion fluid bore hole cleaning connection, comprising: the tuber pipe is transferred and is reached the connector, and the well-flushing goes out the water connector, the nonrust steel pipe connection of car silk, clamping bolt, biplate formula splint, twisted steel, welding type female end quick-operation joint, quick-operation joint sealing rubber pad, welding type male end quick-operation joint, well casing ferrule. The well pipe hoops are two in total, and the double-piece type clamping plates are tightly clamped on the periphery of the well pipe hoops through clamping bolts; the number of the turning stainless steel pipe connecting pieces is three, the welding end of the upper turning stainless steel pipe connecting piece is welded with the welding end of the flushing water outlet connecting port, and the screw thread end is screwed into the well pipe hoop at the upper part; the welding end of the stainless steel pipe connecting piece with the thread is welded with the welding end of the welding type female end quick connector, and the thread end is screwed into the other end of the well pipe hoop at the upper part.

And a quick joint sealing rubber pad is arranged in the welding type female end quick joint.

The lower end of the welding type female end quick joint is connected with one end of the welding type male end quick joint.

The other end of the welding type male end quick connector is welded with a turning wire stainless steel pipe connecting piece at the lower part, and the screw thread end is screwed into a well pipe hoop at the lower part.

The well-flushing water outlet connector is of a bent pipe structure, the air pipe is placed downwards, the connector penetrates through the bent pipe, and the well-flushing water outlet connector is fixedly connected.

The outer surface of the double-piece type clamping plate is fixedly connected with a threaded steel bar to tighten the two double-piece type clamping plates.

The well pipe hoop is made of PVC.

3. Effect

When the well-flushing connecting device and the used spigot-and-socket quick-connection type liquid injection orifice device are used jointly, the orifice connecting piece does not need to be dismantled, so that the time consumed for dismounting is shortened to within 20min from the original more than 2h, and the working efficiency is greatly improved. And when the device is used, the safety protection device consisting of the clamping plate and the twisted steel is added, so that the safety performance in the use process is improved, and the occurrence of the sudden hole washing situation is reduced.
