Therefore, the splicing mode enables the road slab 1 to have certain movement margin, the integrity is improved, and uneven settlement of the two plates is prevented. Moreover, the splicing mode has a simple structure, is convenient to splice and is easy to maintain.

In one embodiment, the connection groove may further include an inclined surface 151, the inclined surface 151 is disposed at one side of the circular hole portion of the key hole and faces the thin portion of the key hole, and the inter-board connection bolt can automatically slide into the thin portion of the key hole through the inclined surface 151 after being inserted into the circular hole portion of the key hole, thereby achieving automatic and accurate splicing of the inter-board connection bolt and the connection groove.

Furthermore, the strong overall linkage can also obviously solve the problem of uneven settlement of the ground, and effectively reduce the possible settlement difference between two adjacent plates.

Specifically, if the left one of the pair of road surface boards 1 is subjected to an abnormal external force, the left portion of the enlarged base 3 is pressed and may be displaced in the left direction, and since the enlarged base 3 has the enlarged bottom and the second projection 33, the pressure against the leftward displacement is greatly increased as compared with the conventional structure. In addition, the splicing structure of the first protrusion 13 has a certain movement margin, and can offset a part of abnormal external force. When abnormal external force is transmitted to another road panel 1, the first bulge 13 can be restored to the original state, and the margin capable of swinging left and right and the stability provided by the enlarged foundation 3 can enable the road panel splicing assembly 100 to have larger capacity of resisting the external force and restoring the original state, so that the uneven settlement of the ground is prevented, and the settlement difference possibly generated by two adjacent plates is reduced. Therefore, the overall performance of the assembly is outstanding, and the system has higher robustness and longer service life.

In addition, the road deck board sets up with enlarging basic cavity and can make the subassembly weight reduce for the subassembly is lighter, further promotes the wholeness in special environment or ecological sensitive area, and the light subassembly is convenient for hoist and mount and transportation. Moreover, the structure is convenient for modular preparation, splicing and dismantling, can be recycled, improves the construction efficiency and is beneficial to saving the cost. Because the application to building materials such as concrete is less, and no redundant building rubbish is generated during dismantling, the component and the pavement system composed of the component have little pollution to the environment, and are completely suitable for construction application in ecological sensitive areas with high requirements on the environment.

The pavement system composed of the components adopts the splicing components with strong overall linkage, and the splicing modes among the components are the same, so that the panel system also has strong integrity, the uneven settlement of the ground can be avoided, and the settlement difference between adjacent plates can be effectively reduced. And moreover, the required structural plate is prefabricated in a factory, and is conveyed to a construction site through a transport vehicle to be spliced, so that the rapid traffic opening can be realized, the time cost is reduced, and the maintenance is convenient. Moreover, the construction access road adopts the assembled temporary road panel, has high technical efficiency, short period, low energy consumption and little environmental pollution, and is completely suitable for construction application in ecological sensitive areas with high requirements on environment. In addition, the construction access road is prefabricated by adopting concrete, so that the post-construction reclamation is more facilitated, the assembled temporary road panel can be dismantled by the post-construction reclamation, the temporary road panel can be recycled, and the comprehensive cost is low.
