Three-layer foaming anti-polishing pad

Abstract

The invention relates to the technical field of anti-polishing pads. The invention discloses a three-layer foaming anti-polishing pad. Mounting plate, the outer wall of the mounting plate is coated with a first bonding layer; one side, far away from the mounting plate, of the first bonding layer is bonded with a first anti-polishing pad; one side, far away from the first bonding layer, of the first anti-polishing pad is coated with a second bonding layer; a first reinforcing net is bonded to the side, away from the first anti-polishing pad, of the second bonding layer. The side, away from thesecond bonding layer, of the first reinforcing net is coated with a third bonding layer, the side, away from the first reinforcing net, of the third bonding layer is bonded with a second anti-polishing pad, the side, away from the third bonding layer, of the second anti-polishing pad is coated with a fourth bonding layer, and the side, away from the second anti-polishing pad, of the fourth bondinglayer is bonded with a second reinforcing net. The three-layer foaming anti-throwing pad has the advantages that the convenience of installation of the anti-throwing pad can be effectively improved,time and labor are saved in the installation process, the mountain rockfall blocking effect can also be improved, and the running safety of a high-speed rail train is guaranteed.

Description

technical field [0001] The invention relates to the technical field of anti-throwing pads, in particular to a three-layer foamed anti-throwing pad. Background technique [0002] There are often rockfalls at the entrance of high-speed railway tunnels, which seriously endanger the running trains and easily cause safety accidents. Rockfalls are a number of stones of different sizes on the mountain or other high places that fall quickly from the cliff or along the slope. Rolling to the ground or low-lying places, rockfalls vary in size and occur all the time. It is a very common geological phenomenon and a normal state of topography and landform changes, but it also poses a long-term threat to human production and life. [0003] Most of the existing rockfalls are blocked by anti-throwing nets, but the meshes of the anti-throwing nets still allow the rolling stones to pass through, resulting in poor blocking effect of rockfalls, and rockfalls seriously affect the safety of high-s...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a three-layer foam anti-throw mat, which can effectively improve the convenience of the installation of the anti-throw mat, save time and effort during the installation process, and can also improve the effect of blocking rockfall, ensuring The safety of high-speed trains and other advantages solves the problem that the current anti-throwing nets still allow rolling stones to pass through, resulting in poor blocking effects of falling rocks, and falling rocks seriously affect the safety of high-speed trains.
