Abstract

The invention discloses a flexible protective net with a main and assistant cable system. The flexible protective net with the main and assistant cable system solves the problems that as for an existing flexible protective net structure, the protective level is lower, and grading cooperative work of the system cannot be achieved. The flexible protective net with the main and assistant cable system comprises uprights, mesh sheets, upper support cables, lower support cables, anchor-pulling cables, end support cables and side anchor-pulling cables. According to the flexible protective net with the main and assistant cable system, the upper support cables and the lower support cables are designed to be corresponding main cables and assistant cables, free gliding of a support system is achieved, force transfer is clearer, the work efficiency of the system is greatly improved, maintenance is convenient, and a high protective level of the flexible protective net can be achieved.

Description

technical field [0001] The invention relates to a structural system of a flexible protective net, in particular to a structural system in which main and auxiliary cables are arranged in the flexible protective net, and belongs to the technical field of disaster prevention structures. Background technique [0002] Flexible protective net is an important slope protection technology in the field of slope geological disaster prevention and control. It is composed of three main parts: interception system (wire rope net or ring net needs to intercept small falling rocks, and a layer of wire grid is added), support system (including anchor rod, anchor rope, base and support rope, column), and energy dissipator. . Form a surface protection for the protection area, thereby preventing the collapse of rock and soil from falling, and playing the role of slope protection. At present, the protection energy level of the commonly used flexible protective net is 500kJ~750kJ. [0003...
