[0002] Engineering support piles and engineering piles are bored and bored piles. Before concrete pouring, a steel cage is often required in the hole. The mud in the hole is in a static state for a long time. The mud, sand and other suspended matter in the mud gradually settle to the bottom of the hole, forming a thicker sediment. If the hole is not cleaned for the second time, a slag layer will be formed at the bottom of the hole, which will directly affect the quality of the bored piles.

[0003] Chinese patent CN216428270U proposes a bored pile slag cleaning device, which includes a conveying pipe, a spiral conveying slurry, a connecting rod and other devices, which can convey the sediment inside the bored pile hole upward to the top of the conveying pipe, and then fall between the collecting pipe and the conveying pipe to be collected, thereby realizing the cleaning of the sediment inside the bored pile hole and improving the forming quality of the bored pile.

[0004] However, the above-mentioned cast-in-place pile slag cleaning device has the following disadvantages when in use: the cleaned slag accumulates inside the device, and the slag needs to be taken out of the device again after the slag cleaning operation is completed, which is troublesome to operate and inconvenient for construction personnel to use. At the same time, the slag is only cleaned by rotating the spiral conveying slurry, and the structure is relatively simple, which reduces the slag cleaning efficiency. Therefore, the utility model proposes a cast-in-place pile slag cleaning device for solving the above problems. Utility Model Content
