Construction method of road slope driving protection net system

Abstract

The invention provides a construction method of a road slope driving protection net system. The construction method of the road slope driving protection net system comprises the steps of trimming a slope, determining hole positions, drilling holes, mounting anchor rods, mounting supporting ropes, mounting grid networks, bundling up supporting rope networks and the grid networks, and mounting steelrope networks. According to the provided technical scheme, the supporting rope networks, the steel rope networks and the anchor rods are combined to form a road protection system which replaces a traditional slope protection system formed by concreting, the manufacturing and construction costs are reduced, local regions with densely developed internal surrounding rock joints or local regions withcollapse risks of a road slope are protected mainly, thus, the local dangerous regions are connected with regions with relatively stable internal surrounding rock of the road slope through the supporting rope networks, the steel rope networks and the anchor rods, the probability of rockfall, flying stones and collapse is reduced, thus, the protection system has good thermal stability, the servicelife of the protection system is prolonged, and the protection effect is improved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a construction method of a road slope active protection net system. Background technique [0002] With the development of the economy, the construction of the road traffic system has become more and more intensive, and the construction of roads has gradually extended to the edge of the mountainous area. Due to the high altitude and complex geographical conditions of the mountainous area, many difficulties have been brought to the construction of the road. Take Pingtang County, Guizhou Province, Southwest my country as an example. The county is located in a humid subtropical monsoon climate zone, with no severe cold in winter and no scorching heat in summer. The county's annual average temperature is 17°C, the hottest monthly average temperature is 25.4°C, the extreme minimum temperature is -7.7°C, the extreme maximum temperature is 38.1°C, the annual average sunshine ho...

AI Technical Summary

Problems solved by technology

This geomorphic feature has poor geothermal stability, and the stability of the mountain structure is different. The road slope is prone to local collapse, weathering and spalling, and collapse. Therefore, corresponding technical measures must be taken during road construction to protect the road slope. For processing, in the prior art, the concrete is generally used for simple potting treatment on the road slope, but this construction method needs to consume a large amount of building material resources on the one hand, and on the other hand, due to the different degree of thermal deformation of the concrete, when the environment When the temperature changes, the concrete is prone to deformation and cracking, which will damage the protection system, affect the protection effect, and even cause accidents where falling rocks or flying rocks destroy vehicles
