Background
Cast-in-situ bored piles are a type of pile defined by classification according to the method of forming the pile. When the cast-in-situ bored pile is formed, slurry needs to be added into the hole in the hole forming process to protect the hole wall in order to conveniently carry drilling slag and prevent the hole wall from collapsing. The slurry is generally composed of water, clay and chemical treatment agent, and has good physical and chemical stability, proper viscosity and small sand content. The mud flowing out of the hole in the hole forming process contains drilling slag which can not meet the wall protection requirement, and can be sent into the hole again through a mud pump for use after being properly treated, and the good wall protection effect of the mud is ensured through continuous circulation treatment of the mud. In the prior engineering, in order to solve the problems of slurry storage and circulation, a long steel casing is generally used to be driven into a riverbed and also used as a slurry pond, and a connecting pipe is arranged between the casings to circulate the slurry. The conventional methods for connecting the casing pipes comprise two methods:
