Floating upright post protective net structure

Abstract

The invention discloses a floating upright post protective net structure and aims to prevent upright posts from being damaged by direct impact of falling rocks. The floating upright post protective net structure comprises the upright posts which are arranged in rows, and a protective net body which is fixed to the upright posts; a front side anchoring component and a rear side anchoring component which are integrally connected with the stratum are respectively arranged on the two sides of each upright post. Each upright post is suspended above the ground through a pair of front side steel rope and rear side steel rope; each front side steel rope is fixedly connected at three points among the upper part of the corresponding upright post, the corresponding front side anchoring component and the lower part of the corresponding upright post and is tensioned; each rear side steel rope is fixedly connected to three points among the upper part of the corresponding upright post, the corresponding rear side anchoring component and the lower part of the corresponding upright post and is tensioned. At least one damper is arranged on each front side steel rope.

Description

technical field [0001] The invention relates to a protective net, in particular to an installation and fixing structure of a protective net and a column. Background technique [0002] In order to prevent the unstable mountain and falling rocks from causing serious harm to people, vehicles, buildings, etc., various protective nets act as "safety guards" for the safety of life and property in modern society. [0003] Common protective nets are mainly composed of fixed columns and steel cable mesh surfaces of different structures. In order to improve the protection capacity, buffer devices such as dampers are often installed. The fixed column is the backbone of the protective net, which is directly fixed to the ground, and its main function is to stabilize and erect the steel cable net surface. The fixed column structure protective net has a simple structure and is convenient for construction. The disadvantage is that if the falling rock directly hits the fixed column, the fix...

AI Technical Summary

Problems solved by technology

The structure of the fixed column structure protective net is simple and convenient for construction. The disadvantage is that if the falling rock directly hits the fixed column, the fixed column cannot buffer and consume the kinetic energy of the falling rock through retreat, and it will be directly damaged by the falling rock, and the entire protective net will lose its protective function.

Although certain foot chains and other devices are installed at the bottom of some fixed columns to buffer the falling rocks by tilting at a certain angle when falling rocks hit the fixed columns, the actual effect of protecting the columns is limited, and it cannot buffer large and medium-sized rockfalls.

In addition, the fixed column is often fixed by driving into the ground to a certain depth. Therefore, there are certain requirements for the soil quality along the protective net. When the soil is loose or hard, it is often necessary to adopt corresponding engineering for the stratum foundation at the position of the column. This will undoubtedly increase the construction cost of the protective net project
