Multistage protection slope horizontal anchor rod reinforced structure

Abstract

The multi-level slope protection horizontal anchor reinforcement structure, the slope protection of the road surface is equipped with multi-level slope protection, and each slope protection section is reinforced with cement anchor blocks and horizontal anchor rods; there is a water guide system between each slope protection section; the laying angle of the cement anchor blocks and The grades of slope protection on the pavement have equal slopes; horizontal anchors are arranged between the cement anchor blocks and the slopes of slope protection at all levels; and the horizontal anchors are arranged parallel to each other. The drainage grooves of slope protection at all levels are set along the slope protection at all levels, and the slope of the drainage groove is equal to the slope of the slope protection at all levels; the drainage groove connects the road surface and the subgrade surface; the structure is sprayed with a cement mortar layer on the surface of the water guiding system It is used to prevent the outflow water from seeping into the roadbed, so as to ensure the service life and quality of the roadbed. The water guide system of the present invention is parallel to the cement anchor block and the transverse anchor bar of the graded slope protection, and can effectively reduce the influence of ground drainage on the stability of the roadbed. The structure is simple in construction and has very good practical performance.

Description

technical field [0001] The invention relates to a multi-stage slope protection horizontal anchor bolt reinforcement structure, which belongs to the technical field of slope protection structures on highway slopes. Background technique [0002] There are two types of engineering slope protection: slope protection and support structure protection. Commonly used measures for slope protection include plastering with mortar or composite soil, sprayed grout, shotcrete, mortared rubble parapet, anchor-spray slope protection, anchor-spray net slope protection, etc. Such measures are mainly used to protect the weathering and spalling of rocks on the slope surface of excavation, chipping, and a small amount of falling rocks and blocks. The slope to be protected should have sufficient stability, and the unstable slope should be supported first and then protected. There are many types of retaining structures, such as retaining walls, anchor retaining walls, anti-slide piles, etc. The...

Problems solved by technology

[0012] The purpose of the present invention is to solve the problems of collapsing, subsidence, local instability and other diseases that occur when the graded slope of the existing road slope encounters soft soil and special collapsible roadbed, so as to realize the stability in the process of road construction and use. Reinforcement to improve the quality and service life of roads
