The pouring of pile foundations is mainly carried on the backs of people or on horses, and is carried out through ordinary chutes. During the pouring process, people cannot stand, which poses a great safety hazard. The pouring is difficult, the pouring is slow, and the pouring quality is difficult to guarantee. The defects of the above-mentioned traditional original pouring method are: during the pouring of the pile foundation, it is inconvenient for people to walk, and in some areas people cannot stand, resulting in low pouring efficiency at the construction site, greater difficulty in pouring, difficulty in guaranteeing pouring quality, greater safety hazards, and increased direct engineering costs of the project; the defects of the ordinary chute pouring method are: the installation of the chute requires manual installation of each section of the chute in turn, which is more cumbersome and needs to be manually dismantled after use.
