[0002] Bored pile construction refers to the process of forming pile holes in the foundation soil by mechanical drilling, steel pipe squeezing or manual excavation at the construction site, placing steel cages in the holes, and pouring concrete to form piles. According to different hole-forming methods, bored piles can be divided into several categories, such as sinking pipe bored piles, bored piles and excavated bored piles. Bored piles are a type of pile defined by pile-forming methods. A mud hole cleaning device for bored pile construction is a device used to clean the drilling mud during bored pile construction. Bored piles are a commonly used construction method for foundation reinforcement and load-bearing structures, and mud is a mixture injected into the borehole during the drilling process for the purpose of cooling the drill bit, stabilizing the steel pipe, carrying flushing agents and suspending soil layers.
