Therefore, the hole (slot) needs to be cleaned and the mud needs to be replaced before pouring concrete. The existing replacement method mainly uses new mud injected from the bottom of the slot hole and old mud overflowing from the top of the slot hole to finally complete the mud replacement. In this method, the new and old mud mix with each other in the slot hole, it is difficult to determine the completion point of mud replacement, it is difficult to recycle and reuse, it is relatively wasteful of mud, and after pouring concrete, the mud is mixed with the previous recycled mud for use, which increases the amount of mud discharge and causes environmental pollution.

[0011] When the concrete is poured, the concrete sinks into the casing, as the concrete in the casing increases, the hole cleaning mud is squeezed into the mud transition cavity of the expansion cylinder, and the valve switch of the mud outlet is opened, so that the hole cleaning mud is discharged into the hole cleaning mud collecting box.
