Multi-step revetment horizontal anchor bolt reinforcement and bottom revetment water drainage mixed structure

Abstract

A multi-step revetment horizontal anchor bolt reinforcement and bottom revetment water drainage mixed structure is divided into a revetment horizontal anchor bolt reinforcement system and a bottom revetment water drainage system. The revetment horizontal anchor bolt reinforcement system is arranged on the upper half portion of a multi-step revetment. The bottom revetment water drainage system is arranged at the bottom of the multi-step revetment. The revetment between the road surface and the bottom surface of a roadbed is arranged in a stepped mode, and each revetment section on the upper half portion is reinforced through cement anchoring blocks and horizontal anchor bolts. The laying angle of the cement anchoring blocks is equal to the gradient of each revetment step on the road surface, and the bottoms of the cement anchoring blocks of each revetment step are embedded in the top of the next revetment step. The horizontal anchor bolts are arranged between the cement anchoring blocks and the surface of each revetment step, and the horizontal anchor bolts are arranged in layers and in parallel. The bottom revetment water drainage system and the revetment horizontal anchor bolt reinforcement system are arranged in a combined mode, the influence of ground drained water on the stability of the roadbed can be effectively lowered, and the multi-step revetment horizontal anchor bolt reinforcement and bottom revetment water drainage mixed structure is easy to construct and quite good in practicability.

Description

technical field [0001] The invention relates to a multi-stage slope protection horizontal bolt reinforcement and bottom slope protection drainage mixed structure, which belongs to the technical field of slope protection structures on highways. 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 wall...

AI Technical Summary

Problems solved by technology

[0012] The purpose of the present invention is to solve the problem that the graded slope surface of the existing road slope is under the situation of different soil layers, especially the soil at the top of the roadbed is stable soil, and the graded slope protection slope surface of the slope surface is unstable soil. Reinforcement and drainage, in order to achieve stable reinforcement during road construction and use, and improve the quality and service life of roads
