Abstract

The invention relates to the technical field of geotechnical engineering, in particular to an anchoring net device and a construction method thereof for the reinforcement and protection of high and steep slopes, comprising a prestressed anchoring device and a flexible mesh pad, the flexible mesh pad is provided with an enlarged cap, and the prestressed anchoring device It is connected with the enlarged cap, and the enlarged cap includes an upper enlarged cap and a lower enlarged cap, and the upper enlarged cap and the lower enlarged cap clamp the flexible mesh pad from both sides of the flexible mesh pad, and both the upper enlarged cap and the lower enlarged cap are connected to the surface of the flexible mesh pad. touch. An anchor net device used for the reinforcement and protection of high and steep slopes of the present application uses a flexible mesh pad and an enlarged cap to apply the anchoring force of the prestressed anchoring device to the slope surface of the high and steep slope to resist the gravity of the broken rock and soil and the Earth pressure, so as to achieve the purpose of protecting the slope, and avoid the difficulty of concrete transportation and poor tamping effect of on-site pouring. Compared with concrete beams, the expansion cap has a small structure and can be prefabricated in factories. It is not only reliable in quality, but also It is convenient for transportation and reduces the construction cost.

Description

technical field

[0001] The invention relates to the technical field of geotechnical engineering, in particular to an anchor net device used for reinforcement and protection of high and steep slopes and a construction method thereof. Background technique

[0002] The mountains and valleys along the Sichuan-Tibet Railway are high and the valleys are deep, characterized by high intensity, high altitude, and large height difference. High and steep natural slopes are widely distributed along the line. The height reaches the kilometer level and the slope reaches 60°. A large number of unstable slopes or dangerous rock masses are distributed on high and steep natural slopes, which are very easy to lose stability and slide under the action of earthquakes, rainfall, etc., forming high-level landslides or dangerous rockfalls, affecting the normal use of railway buildings and structures, and even It may directly damage the bridge and tunnel engineering (tunnel opening or bridge abutmen...
