Ecological supporting and protecting system and construction method using flexible cladding soil nailing wall combined with reinforced earth

Abstract

The invention provides an ecological supporting and protecting system and a construction method using a flexible cladding soil nailing wall combined with reinforced earth. The flexible cladding soil nailing wall comprises a plurality of soil nails, a plurality of connecting structures and flexible cladding; one end of each of the connecting structures is connected fixedly with a corresponding soil nail, and the other end of each of the connecting structures is connected with the flexible cladding; soil nails are arranged fixedly in drilling holes arranged on a side slope, and the flexible cladding covers the surface of the side slope; a reinforced earth retaining wall comprises a reinforced material, a backfill soil layer and a vegetation layer; one end of the reinforced material is connected with the connecting structures, the backfill soil layer is embedded in the reinforced material, the vegetation layer is embedded in the backfill soil layer and is away from the flexible cladding, and the other end of the reinforced material wraps an end portion of the backfill soil layer; an automatic irrigation system comprises an impounding reservoirs and irrigation pipes, inlets of the impounding reservoirs are connected with a water discharging system of the side slope, outlets of the impounding reservoirs are connected with the irrigation pipes and the impounding reservoirs and irrigation pipes are arranged on the reinforced earth retaining wall.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a flexible surface layer soil nail wall combined with reinforced soil ecological support system and a construction method thereof. Background technique [0002] The soil nail wall refers to the support structure composed of soil and surface layer on the side wall of the foundation pit reinforced by soil nails. As a common foundation pit (slope) support type, soil nail wall support is widely used in foundation pit (slope) engineering in non-soft soil sites. It is mostly used in foundation pit (slope) projects that are excavated and supported at the same time. The name of the Chinese invention patent is flexible surface soil nail wall support system and its construction method (application number 201010543317.1). New flexible surface materials (geotextiles, geomembranes, geocomposites, geotechnical special materials) are used to replace traditional rigid surfaces...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a flexible surface layer soil nail wall combined with reinforced soil ecological support system and its construction method, which can solve the greening problem of the existing shotcrete slope protection, and can solve the problem that it is difficult to realize reinforced soil when the width of the backfill area is limited. The design problem of the retaining wall, and at the same time solve the problem of poor plant growth conditions on steep slopes caused by insufficient precipitation in arid areas
