Abstract

The invention provides a flexible surface layer soil nailing wall support system and a construction method thereof. The flexible surface layer soil nailing wall support system comprises a plurality of soil nails, a plurality of connecting structures and a flexible surface layer, wherein one end of each connecting structure is fixedly connected with a corresponding soil nail, and the other end of the connecting structure is fixedly connected with the flexible surface layer; the soil nails are fixed in drill holes which are formed on a side slope; and the flexible surface layer is covered on the surface of the side slope. The soil nails are fixed in the drill holes which are formed on the side slope by grouting, the flexible surface layer is connected with the soil nails through the connecting structures and appropriate pre-stressing force can be applied during connection of the flexible surface layer and the soil nails, so that the flexible surface layer is covered on the side slope after being tensioned and the aim of lowering engineering cost on protection of the side slope through the flexible surface layer soil nailing wall support system is fulfilled.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a flexible surface soil nail wall support system and a construction method thereof. Background technique [0002] The soil nail wall refers to the supporting structure composed of the foundation pit or slope side wall soil and surface layer reinforced with soil nails. As a common type of foundation pit or slope support, soil nail wall support is widely used in foundation pit or slope engineering in non-soft soil sites. The existing soil nail wall support system mainly consists of two parts: soil nail and surface course. Soil nailing refers to the reinforced body formed by placing steel bars, steel pipes or other slender rod materials into rock and soil by drilling, grouting, driving or injecting. The surface layer is a structure that prevents the lateral displacement of the soil slope, bears the earth pressure generated by the active area of ​​the potential sli...
