Geocell composite reinforcing rib ecological retaining wall and construction method thereof

Abstract

The invention discloses a geocell composite reinforcing rib ecological retaining wall and a construction method thereof. The ecological retaining wall comprises retaining wall units sequentially constructed from bottom to top, and each retaining wall unit comprises a bottom geocell layer, a unidirectional geogrid, at least one inverse filter inclusion layer, a bidirectional geogrid and a filling layer. The construction method includes: S1, performing earth excavation and pouring retaining wall rigid strip foundation; S2, laying geocells, and filling filler in the geocells; S3, carrying out unidirectional geogrid return construction; S4, arranging the bidirectional geogrid; S5, repeating the steps until a retaining wall design height is achieved. By adoption of the geocells with a stereo reinforcing rib structure as a bottom layer structure, the geocells are filled with the filler, the unidirectional geogrid is laid at the top of the leveled filler in the geocells, and the inverse filter inclusion layers are arranged while the bidirectional geogrid is arranged between every two composite reinforcing rib layers, structural stability of the ecological retaining wall is guaranteed by layer-by-layer construction, and simplicity in construction is realized.

Description

technical field [0001] The invention relates to the technical field of geotechnical structures, in particular to an ecological retaining wall with composite reinforced ribs in geocells and a construction method thereof. Background technique [0002] In recent years, with the large-scale development of my country's transportation infrastructure construction, my country's economic construction has entered a fast-growing train track. However, as the country continues to strengthen the protection of existing cultivated land, reducing land occupation has become the basis of transportation. An important guiding principle of facility construction, which requires extensive use of support structures and steeper slopes to achieve the purpose of reducing land occupation on the premise of satisfying structural safety and stability during construction. Among them, the retaining wall is widely used because of its relatively safe and stable, economical and durable, and can save land occupat...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide an ecological retaining wall with composite reinforcing ribs in geocells, which can give full play to the advantages of the safety and stability of the three-dimensional reinforcing ribs in geocells and the back-wrapping structure of unidirectional geogrid, and avoid the occurrence of problems caused by the back of the retaining wall. The problem of overturning of retaining wall caused by deformation and displacement
