Retaining wall reinforcement structure and active repair method for retaining wall inclination

Abstract

The invention discloses a retaining wall reinforcement structure, which includes retaining wall bodies. A pavement structure and paving is arranged between the two retaining wall bodies, a protectivepipe is arranged between the two retaining wall bodies in a penetrating mode, and the protective pipe is internally provided with prestress rebars. According to the retaining wall reinforcement structure, the prestress rebars are oppositely pulled on the retaining wall bodies on the two sides, a retaining wall can well be prevented from further leaning, and meanwhile, inclination and deformation of the retaining wall can be restored by adjusting acting force applied by steel cables.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a reinforcement structure of a retaining wall and an active repair method for the slope of the retaining wall. Background technique [0002] Retaining wall is a common form of retaining structure in various engineering constructions, and has been widely used in highways, railways, port engineering, construction engineering and other fields. Retaining walls often adopt gravity type, cantilever type, buttress type, sheet pile type and other forms. [0003] No matter what kind of retaining wall is used, it often has the problem of tilting during use. The common reasons for tilting are: [0004] (1) The filling soil behind the wall is not layered and compacted or the water content of the filling soil is too large, which does not meet the design required compactness, which reduces the internal friction angle of the filling soil and increases the earth pressure, resul...

AI Technical Summary

Problems solved by technology

[0004] (1) The filling soil behind the wall is not layered and compacted or the water content of the filling soil is too large, which does not meet the design required compactness, which reduces the internal friction angle of the filling soil and increases the earth pressure, resulting in the inclination of the retaining wall

[0005] (2) The foundation of the retaining wall is uneven or the foundation is over-excavated and backfilled with plain soil without compaction, or the bad soil quality such as silt and garbage has not been cleaned, resulting in a decrease in the bearing capacity of the foundation, causing the toe of the front wall to sink where the force is the largest, and the retaining wall The earth wall leans forward

[0006] (3) The design of the wall section is unreasonable, such as the wall toe is short, the moment arm is small, the anti-overturning ability is poor, or the back of the wall is too inclined to form a large earth pressure, and the slope of the retaining wall occurs, etc.

The disadvantage of increasing the lateral support method is that there is a need for operating space to set up the lateral support

In urban bridges, there are usually auxiliary roads on the side of the retaining wall, and it is impossible to set up lateral supports

At the same time, increasing the lateral support can only prevent the further inclination of the retaining wall, and cannot repair the existing inclination deformation

[0011] To sum up, the retaining wall often inclines obviously due to external loads. The reinforcement methods commonly used at present are mostly passive reinforcement, which can only prevent the further inclination of the retaining wall, and cannot correct the existing inclination. Deformation is repaired, and the effect of commonly used reinforcement methods is not ideal
