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.
