Problems solved by technology
However, the construction process is relatively complicated, and the quality of the pile is closely related to the construction process. It is an underground concealed project, and the construction quality directly affects the safety of the final structure, which can easily cause quality accidents and leave safety hazards. Therefore, the mud retaining wall is drilled and poured The construction of each sub-item of the pile construction process is very important, especially the determination of the position where the reinforcement cage is lowered to the mud liquid surface is particularly important

The invention discloses a device and method for reducing deviation of a reinforcement cage of a slurry retaining wall cast-in-situ bored pile, and belongs to the technical field of pile foundation engineering construction. The device comprises a soil body and a reinforcement cage in a hole opening, a prefabricated concrete foundation cross fender pile and a steel pile casing are arranged in the soil body, bentonite slurry, a reinforcement cage fixing device and a positioning device are arranged in the hole opening, and the center position of a designed pile position is determined through the prefabricated concrete cross fender pile in the soil body in early-stage measurement; the reinforcement cage is temporarily fixed through the reinforcement cage fixing device, and then the final position of the reinforcement cage is adjusted by comparing the reinforcement cage positioning device with the center point of the cross-shaped fender pile in the soil body. The method is high in construction precision, economical, reasonable, safe and reliable, and the quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of pile foundation engineering construction, in particular to a device and a method for reducing the deviation of a reinforcement cage of a mud retaining wall bored pile. Background technique [0002] For a long time, the mud retaining wall bored pile is a pile foundation construction method widely used in my country's construction. The mud retaining wall bored pile has its own characteristics of strong adaptability, simple construction operation, low equipment investment, and good stability. It is widely used in various bridges, large-scale passages and special foundation treatment projects. However, the construction process is relatively complicated, and the quality of the pile is closely related to the construction process. It is an underground concealed project, and the construction quality directly affects the safety of the final structure, which can easily cause quality accidents and leave safety hazard...
