Shock-resistant buffering and damping structure for underground facility equipment Technical Field The utility model relates to the technical field of underground equipment vibration reduction, in particular to an earthquake-resistant buffering and vibration-reducing structure of underground facility equipment. Background With the rapid development of urban construction, underground facility equipment such as subway tunnels, underground piping, underground substations, etc. occupy an increasingly important position in urban infrastructure. The facilities and equipment are in underground complex environments for a long time, and not only bear stress generated by geological structure change, but also resist external impact forces such as earthquake, construction vibration and the like. Once the urban normal operation is seriously affected and even safety accidents are caused due to the fact that the urban normal operation is damaged by vibration. Therefore, research and development of a high-performance anti-seismic buffering and damping structure for guaranteeing safe and stable operation of underground facility equipment becomes a key technical problem to be solved urgently. The existing underground facility equipment anti-seismic buffering and damping technology mostly adopts a single spring damping or rubber damping structure. The spring damping structure mainly relies on elastic deformation of the spring to absorb vibration energy, but under high-frequency vibration, fatigue failure of the spring is easy to occur, and the spring is difficult to effectively control in a rebound process, secondary vibration of equipment is possibly caused, the rubber damping structure buffers vibration through flexibility of rubber materials, however, the rubber materials are in an underground humid and corrosive environment for a long time, ageing deformation is easy to occur, and the damping performance is greatly reduced along with the use time. In addition, some technologies assist in damping by adding a simple damper, but the damper has a limited damping effect, and cannot realize efficient absorption and conversion of vibration energy. However, when the above-mentioned prior art is applied to a complex vibration environment, there are problems that vibration energy is not sufficiently absorbed and the durability of the vibration absorbing effect is poor.
