Production method of vertical stone blocking net

Abstract

The invention provides a method for preparing a vertical rockfall blocking net, comprising the steps as follows: the strength and range of slope protection are determined and the construction condition is determined; a supporting structure of the rockfall protecting net is arranged on the slope; wasted tyre nets are arranged; and the clearance of the wasted tyre nets is filled up. The method not only can achieve the objective of preventing and reducing the rockfall disasters, but also can achieve the national strategic objective of utilizing the waste resource by consuming a plurality of wasted tyre.

Description

technical field [0001] The invention relates to the field of rolling stone protection, in particular to a method for making a vertical stone blocking net by using waste tires. Background technique [0002] Waste tires belong to a large category of industrial solid waste. Many developed countries have formulated regulations and incentive policies for comprehensive utilization. my country has also incorporated the reuse of waste tires into the National Eleventh Five-Year Science and Technology Development Outline. With the increase of my country's car ownership, the number of waste tires is also increasing year by year. my country produced 60 million waste tires in 2002, and it increased year by year at a rate of about 20%. In 2005, the output exceeded 112 million (second only to the United States, which ranks first). It is estimated that my country will produce waste tires in 2010 Will reach 200 million / year. Statistics show that the formal recycling rate of waste tires in...

Problems solved by technology

[0007] The results of engineering practice and theoretical analysis show that the steel rope stone blocking net technology also has the following shortcomings: First, the decompression ring with a single-pipe ring structure can produce a large buffer deformation, but it is not easy to recover or even exceed its elastic limit. Completely destroyed, thereby reducing or even losing the subsequent buffering performance; second, the steel wire rope mesh system allows a large displacement and deformation of the wire rope mesh, and the rocks or rocks caught will reduce the buffering performance of the mesh and the effective interception height, which will lead to a significant decline in the subsequent interception function of the system, and sometimes the interception function will be lost due to the excessive static load; third, when the impact energy carried by the rolling stone or the collapsed body is high, the steel The column is bent or even toppled due to the excessive bending moment, which reduces or loses the interception function; fourth, the steel rope stone fence system involves a number of paten
