[0018] The following further describes the present invention in detail with reference to the drawings and specific embodiments.

[0019] As Figures 1 - 3 shown, the drainable prefabricated road plate of the present invention includes a plurality of precast panel modules and a series guiding member that connects multiple precast panel modules as a whole.

[0020] Each precast slab module includes a paving slab 1, a connecting member, and a support slab 3; a plurality of drainage holes are provided on the paving slab 1, and the paving slab 1 is paved on the upper end of the support slab 3 through the connecting member; a concave drainage groove 5 is further provided on the upper end of the support slab 3, and the drainage groove 5 communicates with the drainage holes.

[0021] Three support portions are provided at intervals on the upper end of the support slab 3, there are two drainage grooves 5, and one drainage groove 5 is provided between every two support portions; the connecting member connects the paving slab 1 and the support portion of the support slab 3. The connecting member includes a connecting bolt 2 and a threaded hole provided on the support portion. A plurality of threaded holes are provided at intervals along the length direction of the drainage groove 5 on the support portion, and a connecting bolt 2 is correspondingly provided on each threaded hole, and the connecting bolt 2 is also connected to the paving slab 1, so as to connect the paving slab 1 and the support slab 3 into a whole. The cross-section of the drainage groove 5 is an inverted trapezoid with a long upper end and a short lower end.

[0022] A plurality of drainage holes are provided at the part of the paving slab 1 facing the drainage groove 5. The plurality of drainage holes are provided at intervals along the length direction of the drainage groove 5. After the series guiding members connect a plurality of precast slab modules into a whole, the drainage grooves 5 of the plurality of precast slab modules are also connected into a whole and extend into the roadside drainage ditch or drainage well.

[0023] The series guiding member includes a connecting track 4; a reserved hole 31 is provided at the lower end of the support slab 3 of each precast slab module, and the length direction of the reserved hole 31 is the same as the length direction of the drainage groove 5; the connecting track 4 penetrates through the reserved holes 31 of a plurality of support slabs 3 to connect a plurality of support slabs 3 into a whole. The series guiding member includes at least two parallel and spaced-apart connecting tracks 4; at least two parallel and spaced-apart reserved holes 31 are provided at the lower end of each support slab 3.

[0025] The drainable assembled precast road slab of the present utility model has the following advantages:

[0026] High drainage efficiency. The paving slab 1 is provided with drainage holes, so that rainwater or other accumulated water on the road surface can quickly enter the drainage groove 5 through these drainage holes and then enter the drainage system. This greatly reduces the situation of road surface water accumulation and improves the traffic capacity of the road, especially in the rainy season or humid areas.

[0027] Excellent anti-slip performance. Since the paving slab 1 is provided with drainage holes, the surface of the paving slab 1 is not easy to accumulate water, so the problem of road surface slipperiness caused by water accumulation is reduced. This enhances the safety performance of the road, especially when driving in rainy days and at night.

[0028] Long service life: Due to the high drainage efficiency, the erosion of the road by accumulated water is reduced, thereby prolonging the service life of the road slab.

[0029] Convenient installation and maintenance: The precast road slabs adopt modular design, with simple and fast installation, which can greatly reduce the construction time and cost. At the same time, due to its stable structure, it is relatively easy to maintain.

[0030] Environmental protection and energy conservation: In the manufacturing process, environmentally friendly materials and processes can be used to reduce the impact on the environment. At the same time, due to the high drainage efficiency, the environmental pollution and ecological damage caused by waterlogging are reduced.

[0031] Strong adaptability: The precast road slabs can adapt to different climate conditions, topographies and traffic demands. Whether it is an urban road, a rural road or an industrial park road, it can be customized according to actual needs.

[0032] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
