Description
Technical Field
[0001] This utility model relates to the field of hole cleaning devices, specifically a hole cleaning device for rotary drilling cast-in-place piles. Background Technology
[0002] In pile foundation construction of building engineering, rotary drilling cast-in-place piles are widely used due to their advantages such as fast drilling speed and strong adaptability. However, after rotary drilling, a large amount of sediment remains at the bottom of the hole. If this sediment is not removed in time, it will seriously affect the bearing capacity and construction quality of the cast-in-place pile. At present, the commonly used hole cleaning methods mainly include mud pumping, mud replacement, and slag removal. Mud pumping involves using a mud pump to extract the mud and sediment from the bottom of the hole together. Mud replacement involves injecting new mud to replace the old mud containing sediment in the hole. When using a mud pump to extract sediment for hole cleaning, a long pipeline needs to be connected to the mud pump and placed into the borehole. Existing hole cleaning sites do not have storage facilities for mud pumps before and after use, resulting in the pipelines being scattered and piled up on site when the mud pump is deployed, occupying space and making it inconvenient to organize and store. Utility Model Content
