[0011] Beneficial Effects

[0012] The first frame is assembled with the second frame, and the frames can be separated and disassembled, which improves the efficiency of construction and disassembly, greatly reduces the occupied space, is convenient for transportation, is conducive to construction, and can be reused. Moreover, the prefabrication of various components in the factory can improve the quality of the shed hole compared to on-site production. In addition, when falling rocks collide with the structure, they are buffered by elastic energy-absorbing components, which avoids the impact damage to the shed hole caused by the concentrated release of the kinetic energy of the falling rocks in one part. Energy is transmitted by soft contact and the strong impact force caused by hard collision is avoided. For example, the external force on the frame is buffered by compression springs, thereby protecting the frame, ensuring construction safety, and increasing the service life of the frame.
