Construction method of high retaining wall with slab-rib cast-in-place anchor

Abstract

The invention relates to a construction method for a slab rib type cast-in-situ anchor high retaining wall, comprising the steps of: 1) construction preparation; 2) slope soil slope treatment; 3) construction work platform erection; 4) interface reinforcement board laying; ) Wall inner formwork and wall back external formwork support; 6) Retaining wall rib concrete pouring; 7) Wall back filling body construction. The beneficial effects of the present invention are: the present invention provides support for the hanging horizontal plate through the support vertical rod and the top support beam respectively, which reduces the difficulty of cantilever support for the hanging horizontal plate; at the same time, the present invention adopts an assembled bottom plate and a support shoe The cap defines the position of the stand pole, which reduces the difficulty of laying the stand pole and improves the quality of the stand pole arrangement; the present invention is provided with a first hanging basket and a second hanging basket, and the first hanging basket can be limited by the position control cable. The heights of the hanging baskets and the second hanging baskets define the lateral positions of the first hanging baskets and the second hanging baskets through the connecting grooves of the slide rails, which reduces the difficulty of arranging the first hanging baskets and the second hanging baskets.

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...
