High-steep slope supporting method

Abstract

The invention provides a high-steep slope supporting method. The method comprises the following steps that a slope body is trimmed into the slope body with a 45-degree slope face, a ditch is dug belowthe slope body, the ditch is dug to be of a lower narrow and upper wide structure, a gradient is formed between the ditch and a road face, and the width of the bottom of the ditch before grouting is1.2 m; a plurality of slope face steps are built on the surface of the slope body, and the slope face steps are right-angled steps, anchor cables are firstly hit into the slope faces, the depth is determined according to actual geological exploration, the anchor cables are arranged at equal intervals along the transverse direction and the longitudinal direction on the slope faces in a distributedmode, the distance between every two adjacent anchor cables is 1 m, then anchor rods are hit, and the position of each anchor rod is arranged to be in the middle position of every two adjacent anchorcables; grouting reinforcement is carried out on the anchor cables and the anchor rods, moreover, concrete size grouting is sprayed on the slope faces, the slope face steps and the surface of the ditch for reinforcement, and the width of the bottom after the supporting and grouting is carried out is 1 m. According to the method, the problems that the side slope is difficult to maintain and the potential safety hazard of the high-steep slope is large caused by inconvenience mountainous area traffic, changeable climate and water damage are solved; and the invention belongs to the field of slopesupporting.

Description

technical field [0001] The invention relates to a side slope support method, which belongs to the field of side slope maintenance. Background technique [0002] With the rapid development of the economy, the requirements for the convenience of transportation in various regions are getting higher and higher, and a large number of railways, expressways, tunnels and other transportation facilities have been built in mountainous or hilly areas, and high and steep slopes have become threats to the safe operation of roads. Tough problem, due to inconvenient transportation in mountainous areas, changeable climate, and water damage, it is difficult to maintain slopes. Contents of the invention [0003] The object of the present invention is to: provide a kind of high and steep side slope support method, described high and steep side slope refers to that slope is about 45 degrees, and height is more than 5 meters, to solve the problem of inconvenient traffic, changeable climate and...
