The multi-layer steel mesh 605 supports each filling structure, which can make the filling structure less likely to be damaged by force.

[0030] When working, firstly, the first frame assembly 1, the second frame assembly 2, the third frame assembly 3, the fourth frame assembly 4 and the bottom assembly 5 are snap-fitted and connected together in order from top to bottom;

Then, the number of each component is increased according to the actual width and length of the roadbed, and the first buffer module 106 and the first slot 105 of the adjacent components are snap-connected. Together, during the operation of the roadbed, when subjected to external force, the first buffer module 106 and the second buffer module 506 are used for buffering and shock absorption, the elastic force of the spring 109 is used for buffering, and the damper 110 inside the spring 109 is used for auxiliary rebound. By setting the first buffer module 106, it can play a buffering role when subjected to a large external force, and the spring 109 can play a certain buffering role when subjected to force, so that the roadbed is not easily damaged when subjected to a large external force, and the various filling structures are supported by the multi-layer steel mesh 605, so that the filling structure is not easily damaged by force. When encountering rainy weather, the water is drained through the first drainage hole 102, the second drainage hole and the third drainage hole 503, and the water flow is guided by the first guide groove 103 and the second guide groove 504. The drainage structure is set to drain the rainwater in time, which can prevent the roadbed structure from being corroded by rainwater and causing collapse. With the mutual cooperation of various components, the anti-subsidence effect is better.
