[0021] FIG1 is a schematic structural diagram of an embodiment of the utility model. DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] The present invention has ten layers from bottom to top:

[0024] The first layer is a 300mm thick graded crushed stone layer 1 with a compaction coefficient > 0.95 and a moisture content controlled within the allowable range. After treatment, the characteristic value of the foundation bearing capacity f ak > 200kPa meets the bearing capacity requirements.

[0025] The second layer is a 50mm thick, C20 concrete cushion 2.

[0026] The third layer is a 4mm thick waterproofing membrane layer 3, which is made of SBS and is turned up 200mm above the ground. This layer is set to ensure that the groundwater level does not penetrate into the site and prevent the shielding layer from rusting.

[0027] The fourth layer is a 50mm thick, C25 fine stone concrete layer 4, which is smoothed as it is laid.

[0028] The fifth layer is the shielding layer 5, which is the core shielding structural net of the floor and is made of steel plate mesh.

[0029] The sixth layer is a 40mm thick, C15 fine stone concrete layer 6, which is smoothed as it is laid; this layer is specially set to prevent welding slag from falling into the shielding net when welding steel bars in the later stage.

[0030] The seventh layer is a 250mm thick, C30 reinforced concrete layer 7, which is smoothed as it is laid. After the strength reaches the standard, the surface is polished. A steel mesh consisting of double-layer bidirectional 14 steel bars @ 150 x 150 is buried in the reinforced concrete layer 7. This layer is the core ground bearing layer. All steel bars in the floor must be welded, and bundling is not allowed. After welding, the welding slag and other waste materials are removed, and no independent solid particles are allowed to remain in the floor. The side of the steel mesh is fixed to the shielding layer 5 by spot welding.

[0031] The eighth layer is a 25mm thick corundum wear-resistant layer 8, with a corundum content of 5ka / m2 and sprayed with a special curing agent.

[0032] The ninth layer is an epoxy glue layer 9, which is mainly used as an adhesive to bond the eighth layer and the tenth layer together.

[0033] The tenth layer is a 5 mm thick epoxy mortar self-leveling surface layer 10, which meets the harsh working conditions of the air-cushion vehicle and ensures the normal passage of the air-cushion vehicle.

[0034] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
