Pile-bearing supporting arm type retaining wall

Abstract

The invention discloses a pile-bearing supporting arm type retaining wall. The pile-bearing supporting arm type retaining wall comprises a bottom plate, a vertical arm fixed to the bottom plate and a rib plate used for connecting the bottom plate with the vertical arm; and a cast-in-situ bored pile is fixedly arranged at the bottom of the bottom plate, and the top of the cast-in-situ bored pile extends upwards into the bottom plate. According to the pile-bearing supporting arm type retaining wall, the cast-in-situ bored pile is only arranged below the bottom plate of the supporting arm type retaining wall, the cast-in-situ bored pile is in rigid connection with the bottom plate, the structure is simple, and the stress and force transmission ways are clear; the cast-in-situ bored pile has high pressure resistance, pulling resistance and horizontal external force bearing capacity; and the bottom plate transmits the dead weight, the upper load, the pressure borne by the vertical arm and other loads to a pile foundation, then the loads are transmitted to foundation soil through the pile foundation, and the purpose of improving the anti-overturning force, the anti-sliding force and the foundation bearing capacity on the premise that the size of the bottom plate is not increased is achieved.

Description

technical field [0001] The invention belongs to the field of protective structures, in particular to a retaining wall. Background technique [0002] At present, the buttress-type retaining wall is usually composed of a base plate, a vertical arm fixed on the base plate, and a rib plate connecting the base plate and the vertical arm. The stability is mainly maintained by the fill soil on the base plate and the rib plate. rice. Due to the small amount of masonry, simple structure and convenient construction, the buttress retaining wall can adapt to the soft foundation and has better stability than the buttress retaining wall. Improvements in anti-overturning and anti-skid forces have been developed rapidly. [0003] Nevertheless, the anti-overturning and anti-sliding forces of the existing cantilever retaining walls are still limited, and it is impossible to solve the problem that the foundation bearing capacity does not meet the base stress without reducing the size of the ...

AI Technical Summary

Problems solved by technology

[0003] Nevertheless, the anti-overturning and anti-sliding forces of the existing cantilever retaining walls are still limited, and it is impossible to solve the problem that the foundation bearing capacity does not meet the base stress without reducing the size of the bottom plate, especially in high fill There are certain limitations in the application of subgrades, soft soil foundations, and subgrades in karst areas, which hinder the promotion and application of this type of retaining wall

[0004] At present, there is no buttress-type retaining wall that can solve the problem that the bearing capacity of the foundation does not meet the foundation stress without increasing the size of the bottom plate, and can improve the overturning and sliding resistance
