A honeycomb geocell retaining wall with ecological restoration function and its construction method

Abstract

The invention provides a honeycomb geocell retaining wall with ecological restoration function and a construction method thereof, which includes a foundation arranged on the ground and a wall arranged on the foundation. Reinforced cushion layer, composite geomembrane, reinforced polypropylene storage and drainage module, filament geotextile and honeycomb geocell; the foundation and reinforced cushion layer include reinforced gray soil modified loess, polypropylene two-way geogrid and drainage pipe, polypropylene two-way geogrid and drainage pipe. There are multiple bidirectional propylene geogrids and they are arranged in parallel in the reinforced gray soil improved loess; the drainage pipes in the reinforced cushion and the drainage pipes in the foundation are respectively connected to the reinforced polypropylene storage and drainage modules. The honeycomb geocell retaining wall with ecological restoration function provided by the present invention has high bearing capacity and dynamic performance, strong anti-sliding and anti-erosion capabilities, and can be filled with gravel soil layers inside, and can be filled with gravel soil layers. Planting grass in the middle can not only effectively prevent water and soil erosion, but also has a greening effect, thereby achieving an effective combination of ecological restoration and engineering management. The construction method is simple, the construction is convenient, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of geological engineering construction, and relates to a honeycomb geocell retaining wall with an ecological restoration function, and also relates to a construction method of the retaining wall. Background technique [0002] As one of the treatment technologies in geotechnical support engineering, retaining wall is widely used in retaining projects such as slopes, embankments, and dams. Most of the traditional retaining walls use masonry rubble, concrete, etc. as the construction materials of the retaining wall. Because these materials have high rigidity, but low tensile strength, shear strength and tensile strain, the retaining wall often occurs after a period of use. The wall is damaged, and once the retaining wall is damaged, it is difficult to repair due to its strong integrity, the repair cost is high, and the later maintenance work is cumbersome. At the same time, due to the complex construction of t...
