Construction method of plate rib type cast-in-place anchor rod high retaining wall

Abstract

The invention relates to a construction method of a plate rib type cast-in-place anchor rod high retaining wall. The construction method comprises the following steps of 1) construction preparation; 2) slope surface treatment of a side slope soil body; 3) construction operation platform erecting; 4) interface reinforcing plate paving; 5) wall surface inner mold and wall back outer mold erecting; 6) retaining wall rib plate concrete pouring; and 7) wall back filling body construction. The construction method has the beneficial effects that a support vertical rod and a shore hanging beam are correspondingly used for supporting a hanging transverse plate, so that the difficulty of cantilever erection of the hanging transverse plate is reduced; meanwhile, the position of the support vertical rod is limited by an assembly type bottom plate and a support boot cap, so that the difficulty of arranging the support vertical rod is reduced, and the quality of arranging the support vertical rod isimproved; and a first hanging basket and a second hanging basket are arranged, the height of the first hanging basket and the height of the second hanging basket can be limited through a position control inhaul cable, the transverse positions of the first hanging basket and the second hanging basket are limited through sliding rail connecting grooves, and the arrangement difficulty of the first hanging basket and the second hanging basket is reduced.

Description

technical field [0001] The invention relates to a construction method for a slab-rib type cast-in-place bolt high retaining wall, belongs to the field of foundation and foundation engineering, and is suitable for retaining wall construction projects. Background technique [0002] In recent years, bolt technology has been widely used in slope support, surrounding rock anchoring, landslide control, cavern reinforcement, high-rise building foundation anchoring and other projects, and has the characteristics of practicality, safety and economy. Compared with the gravity retaining wall, the slab-rib anchor retaining wall has the advantages of light structure weight, and can exert the anti-lifting capacity of the slope soil, and has been widely used in slope support engineering. During the construction of the slab-rib anchor retaining wall, the setting of the construction platform, the setting of the formwork, and the overall control of the supporting structure are often the key p...
