The side wall of the isolation barrel 1 is provided with a diversion hole 1b, one end of the diversion pipe 3 is communicated with the diversion hole 1b, and the other end of the diversion pipe 3 is communicated with the inlet of the liquid storage tank 2.
When a rat hole needs to be drilled on the ground, the first end of the isolation barrel 1 is inserted into the ground and fixed. The wash pipe is inserted into the isolation barrel 1 from the wash pipe insertion hole 1a on the second end of the isolation barrel 1, and the wash pipe can erode the ground in the isolation barrel 1, so that a rat hole is formed. The flow guide holes 1b are communicated with the inlet of the liquid storage tank 2 through the flow guide pipe 3, and in the process of punching out the rat hole, liquid which is returned and discharged from the unformed rat hole can be gradually accumulated in the isolation barrel 1, flows out of the flow guide holes 1b and flows into the liquid storage tank 2 through the flow guide pipe 3. The liquid can not flow out to the ground, and can not influence the walking of workers and ground equipment.
Alternatively, the minimum height of the diversion holes 1b may be higher than the maximum height of the liquid storage tank 2. Facilitating the liquid to flow into the liquid storage tank 2.
