Multi-stage reinforced soil retaining wall structure and construction method

Abstract

The invention discloses a multi-stage reinforced soil retaining wall structure and a construction method, and belongs to the technical field of civil engineering. The retaining wall structure comprises multiple stages of retaining wall panels and filling soil inside the retaining wall panels from bottom to top, a retaining wall foundation reinforcing structure is arranged in a foundation at the bottom of the retaining wall panels, and the foundation supporting capacity is improved; the multiple stages of retaining wall panels are sequentially retracted inwards in a step shape from bottom to top, so that the structure is more stable; a waterproof area is arranged at the top of the filling soil, so that heavy rain scouring can be avoided; a rib material reinforcement assembly connected with the retaining wall panels is arranged on the side, close to the retaining wall panels, in the filling soil laid in a layered mode, the other side of the rib material reinforcement assembly is connected through a longitudinal fixing structure, the lower end of the longitudinal fixing structure extends into the foundation, the retaining wall panels and the filling soil on the inner sides of the retaining wall panels can form a whole by means of the rib material reinforcement assembly and the longitudinal fixing structure, the phenomenon of differential settlement is avoided, and the integrity and stability of the retaining wall structure are improved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a multi-stage reinforced earth retaining wall structure and a construction method. Background technique [0002] At present, the reinforced materials such as geogrids laid in the existing reinforced earth retaining walls are often in a state of not being fully tensioned, or often appear to be pulled out due to insufficient compaction of the filler and insufficient fixation of the reinforcement. , which reduces the reinforcement effect of the reinforced soil structure, and then affects the overall stability of the retaining wall, restricting the popularization and application of the structure. In addition, in the existing reinforced earth retaining wall, the reinforcements of each layer are mostly laid with equal lengths, resulting in a waste of reinforcements. In the current multi-level reinforced earth retaining wall, the reinforcement structure in each le...

Problems solved by technology

[0002]At present, the reinforced materials such as geogrids laid in the existing reinforced soil retaining walls are often in a state of incomplete tension, or often appear due to insufficient filling. The phenomenon of being compacted and the reinforcement not fully fixed and pulled out reduces the reinforcement effect of the reinforced soil structure, which in turn affects the overall stability of the retaining wall and restricts the popularization and application of the structure

In addition, in the existing reinforced earth retaining wall, the reinforcements of each layer are mostly laid with equal lengths, resulting in a waste of reinforcements

In the current multi-level reinforced earth retaining wall, the reinforcement structure in each level of the retaining wall structure is mostly independent, and the reinforcements between different levels of retaining walls and the inner layers of the same level of retaining walls are independent of each other, resulting in inter-level retaining walls and The inter-story reinforced structure lacks relevance and integrity, which in turn affects the integrity and stability of the multi-level reinforced earth retaining wall structure

At the same time, the existing reinforced earth retaining wall structure often produces uneven settlement due to the large difference in stiffness of the foundation structure, which affects the overall stability of the reinforced earth retaining wall structure
