Description

Technical Field

[0002] Before pouring, the bored pile needs to be cleaned. Specifically, the silt at the bottom of the bored pile needs to be sucked away. The existing bored pile hole cleaning device includes a mud pump and a suction pipe. When cleaning the hole, the suction pipe is lowered to the bottom of the bored hole, and then the mud pump sucks away the silt at the bottom of the bored hole through the suction pipe.

[0003] A secondary hole cleaning device for bored piles with publication number CN218990173U has the following defects during use:

[0004] The utility model has a reasonable structure and can form an air-slurry mixture with more uniform density, thereby increasing the rising speed of the overall mortar in the conduit to a certain extent, which is beneficial to improving the efficiency of cleaning the bored pile holes. However, in actual use, the density of some silt settled in the holes is too large. If the silt is not diluted and stirred, it is very likely to clog the pipeline during the suction process, causing the device to fail to operate normally. For this reason, we propose a rotary drilling bored pile hole cleaning device. Utility Model Content
