Problems solved by technology

[0003] The foreign passive flexible protective net test, curtain protective net test and flexible shed tunnel test basically use the existing hillside to carry out the impact test. The disadvantage is that the test site is easily restricted by the site environment, and the test site is often far away from the urban area. The cost of each test is relatively high and takes more time

Abstract

The invention provides a large-scale integrated platform capable of full-scale impact test of various flexible protective structures. The platform comprises the following parts: a reaction wall for installing a passive flexible protective net test model and a curtain net test model, a detachable construction platform, a ground anchor trench for installing a flexible shed tunnel test model, a lifting device for lifting and releasing an impact test block and an impact slider, a slide and a slide support for providing horizontal impact velocity of the impact slider, an observation platform for erecting a high speed camera, and a set box for burying sensor data lines. The large-scale integrated platform provided by the invention can be built in the nearest site, and the test site is not limited by the on-site environment, which obtains low experiment cost and high efficiency, and can conveniently and repeatedly perform the impact test and data acquisition.

Description

technical field [0001] The invention relates to the technical field of protective nets, in particular to a large-scale comprehensive platform that can be used for full-scale impact tests of various flexible protective structures. Background technique [0002] my country is a mountainous country, especially in the western and southeastern mountainous areas. Various geological disasters are hard to prevent, and rockfall disasters on slopes are particularly obvious. They occur suddenly and frequently, posing a serious threat to driving safety and people's lives and property. Passive flexible protective nets, curtain-type protective nets and flexible shed tunnels are relatively cutting-edge rockfall disaster prevention technologies on slopes. These three technologies use steel columns, steel wire ropes and flexible nets as main components, and can be used without destroying the natural conditions of the original slope. Prevent and control geological disasters such as slope colla...
