Abstract

The invention relates to a vertical reinforcing rib reinforced bag grouting pile and a construction method. The pile mainly comprises a prefabricated pipe pile, a prefabricated enlarged toe pile end with one part of the prefabricated pipe pile, a bottom filling enlarged toe pile end, a vertical reinforcing rib, a multi-section back expansion rib, a fixed disc, a bag, a steel plate pile tip, a pipe pile joint, a separate orifice positioning steel plate, a pile periphery reinforcing area, a grouting expanded bottom, a steel plate pile tip top pipe element, a top anchor plate and a foundation baseplate; pile connecting holes are respectively formed in the top and the bottom of the pipe pile; and an upper-section pile and a lower-section pile are connected through a pile connecting rod. An integral circular connecting inner sleeve and a separate arc connecting outer plate with a reverse triangular flange plate are sleeved in the pile connecting place by a stud and a nut. The technical method is convenient to construct, low in construction cost and low in technical requirements on engineering constructors, and can greatly improve the bend and shear resistance of the whole foundation pile. The method is simple in construction process, high in operability, convenient to control the quality, obvious in economic benefit and prominent in treatment effect.

Description

technical field [0001] The invention relates to a vertical rib-reinforced bladder type grouting pile, in particular to a vertical rib-reinforced bladder type grouting pile and a construction method, belonging to the technical field of building pile foundation engineering. It is mainly applicable to technical fields such as building foundations and subgrade engineering foundation treatment. Background technique [0002] Prefabricated pipe piles are one of the pile foundation products widely used in my country's construction projects, but there are common problems in the on-site splicing of pipe piles. The conventional splicing methods such as welding, the welded joints are greatly affected by the weather and the quality of the operators, and the quality is usually not easy to guarantee. In order to speed up the construction period, the cooling time of the weld is usually not enough, the pile is pressed into the soil, the weld is cooled rapidly when it meets groundwater, the we...
