Assembly type spring energy dissipation cushion protecting structure for preventing landfall and rockfall of top of shed chamber

Abstract

The invention discloses an assembly type spring energy dissipation cushion protecting structure for preventing landfall and rockfall of the top of a shed chamber. The assembly type spring energy dissipation cushion protecting structure for preventing landfall and rockfall of the top of the shed chamber is characterized in that a light energy dissipation cushion structure is formed by assembling spring energy dissipation blocks, each spring energy dissipation block consists of a spring framework and a rubber shell, each spring framework is mounted in the corresponding rubber shell, the spring energy dissipation blocks are connected by connecting gaskets and screws to form the energy dissipation cushion, the energy dissipation cushion is fixed on the top of the shed chamber, and a waterproof layer is arranged between the cushion and the top of the shed chamber. The assembly type spring energy dissipation cushion protecting structure for preventing landfall and rockfall of the top of the shed chamber is good in energy dissipation effect, impact energy of rockfall can be effectively reduced under the effect of impact load of the rockfall, the impact force of the rockfall is reduced, and impact lasting time of the rockfall is prolonged. The spring energy dissipation blocks can be produced and manufactured industrially, are conveyed to a construction site and are directly mounted, construction is facilitated, and construction cost can be reduced effectively. The assembly type spring energy dissipation cushion protecting structure for preventing landfall and rockfall of the top of the shed chamber is simple to change and operate, and safe running of the shed chamber can be guaranteed in time.

Description

technical field [0001] The invention relates to an energy-dissipating structure for preventing collapse and rockfall on the roof of a shed or an open tunnel, and belongs to the field of road engineering and disaster prevention and control engineering. Background technique [0002] In the construction of road projects such as highways and railways, sheds or open tunnels often appear in areas prone to landslides and rockfall disasters to prevent rockfall from harming lines and people's lives and property. Especially in the mountainous areas of our country, the hillside is steep. Once a rockfall disaster occurs, the instantaneous impact force of the falling rock on the roof of the shed is quite huge. Therefore, special treatment must be done on the roof of the shed to reduce the impact of the rockfall and prolong the impact The purpose of preventing sheds from being damaged by falling rocks has always been the purpose. At present, the commonly used protective structure on the ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a light-weight assembly type energy-dissipating cushion protection structure on the top of the shed, which can greatly reduce the self-weight of the energy-dissipating cushion on the top of the shed, and can effectively ensure the impact capacity of the energy-dissipating cushion against falling rocks. Solve technical problems such as heavy weight, poor cushioning effect, and difficult replacement of the backfill buffer cushion on the roof of the existing shed
