In the scheme, the two end surfaces between the drainage ditches 17 at the two sides of the floor slab 3 can also be processed into non-wetting surfaces, and then the non-wetting surfaces at the two ends are transversely provided with the combined waterproof drainage pieces with the hydrophilic substances and the non-wetting substances spaced from each other, so that the water flow at the two ends of the floor slab 3 is drained to the drainage ditches 17.

In this embodiment, when the upper surface of the combined vibration-proof noise-reduction floor has waterproof performance, the drainage ditch 17 can be processed on two sides or around the combined vibration-proof noise-reduction floor, so that the fall of the downpipe is larger, and the drainage effect is better.
In the embodiment, the floor slab 3 can be directly processed by the vibration-proof noise-reducing material with better mechanical and structural properties, so that the production cost is reduced and the working efficiency is improved.
In the present embodiment, the waterproofing technique and solution are not limited to the drop-type surface energy waterproofing system and the blocking-guiding type surface energy waterproofing system, and any other suitable surface energy waterproofing technique or suitable waterproofing technique or solution may be applied.
