Problems solved by technology
The performance of the protective system determines the quality of the protective effect. However, there is currently no test platform for testing the performance of the protective system in China. Therefore, it is particularly important to perform the rockfall impact test. How to simulate the process of rockfall impacting the flexible protective system will give the test a foothold. Ground, if this technical problem cannot be effectively solved, it is impossible to carry out the system dynamic detection test
[0003] However, the foreign passive flexible protection system test basically uses 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, and the cost of each test is relatively high. more time spent

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: a dynamic impact test platform for a flexible protection system, including an impact test block 3 for simulating falling rocks, a lifting device 2 for lifting and releasing the impact test block 3 and a flexible The protection system test model 4 also includes a reaction wall 1 for installing the flexible protection system test model 4, and a foundation pit 5 that provides a recoil space for the impact test and plays a protective role; the reaction wall 1 is vertically arranged on the foundation One side of pit 5.
[0023] The lifting device 2 is used to complete the installation of the flexible protection system test model 4 and the lifting of the impact test block 3, and release the impact test block 3 after the impact test block 3 reaches the required height of the test through the automatic release device, so that it can fall freely. Impact t...

The invention discloses a dynamic impact test platform for a flexible protection system. The dynamic impact test platform for the flexible protection system comprises an impact test block used for simulating a falling stone, lifting equipment used for lifting and releasing the impact test block and a flexible protection system test model, and further comprises a reaction wall used for installing the flexible protection system test model and a foundation pit used for supplying a back impact space for an impact test and playing a protection role; the reaction wall is vertically arranged on one side of the foundation pit. According to the dynamic impact test platform for the flexible protection system, the test platform can be built on a nearby field, the flexible protection system test model is installed through the reaction wall, a test site is not limited by the on-site environment, the test equipment does not need to be carried to a farther mountain slope for every test, the test cost is low, and the efficiency is high; the impact test and data acquisition can be conveniently and repeatedly performed.
Description
technical field [0001] The invention relates to the technical field of slope protection, in particular to a dynamic impact test platform for a flexible protection system. Background technique [0002] Slope rockfall is a natural disaster that often occurs in mountainous areas of our country. It occurs suddenly and frequently, and poses a serious threat to driving safety and people's lives and property. Passive flexible protection is a relatively new rockfall disaster prevention technology for slopes. This technology uses steel wire ropes and flexible nets as the main components, and adopts the protection principle of "softness overcomes rigidity", which can prevent and control slopes without destroying the natural conditions of the original slope. Geological and climatic disasters such as landslides, blasting flying rocks, falling objects, and avalanches. The performance of the protective system determines the quality of the protective effect. However, there is currently no...
