Description

Technical Field

[0001] The utility model relates to the technical field of building pile foundations, in particular to a hole cleaning device for building pile foundation construction. Background Art

[0002] Pile foundation hole cleaning refers to the work of cleaning the holes of the pile foundation (or pile foundation) during the construction process. The pile foundation is a deep foundation structure, usually used to support buildings or other engineering structures. When building a pile foundation, construction workers will first drill holes in the ground or rock, and then pour steel bars and concrete into the holes to form a pile foundation. During the drilling process, some debris will be generated, such as gravel, soil, water, etc. If these debris are not cleaned up in time, it will affect the quality and stability of the pile foundation. Therefore, before pouring concrete, the holes need to be cleaned to ensure the cleanliness and dryness of the inside of the holes to ensure the quality of concrete pouring.

[0003] In the process of cleaning holes, a pile foundation hole cleaning device is one of the indispensable equipment. Most of the hole cleaning devices on the market are unable to mix and blend the debris and soil in the holes with the poured mixed soil, thereby improving the cleanliness and stability of the pile foundation holes. To this end, we propose a hole cleaning device for building pile foundation construction. Utility Model Content
