In the scheme, the two end surfaces between the drainage ditches [17] at the two sides of the floor slab [3] can be processed into non-wetting surfaces, then the non-wetting surfaces at the two ends are transversely provided with combined waterproof drainage parts with hydrophilic substances and non-wetting substances at intervals, and water flows at the two ends of the floor slab [3] are drained to the drainage ditches [17 ].
With reference to fig. 9, in order to improve the bonding strength between the vertical wall surface and the floor slab [3], the joint between the floor slab [3] and the wall surface is processed into a lower step [19], so that the vertical wall surface is embedded in the step [19] of the two floor slabs [3], and the vertical wall surface is prevented from moving.

Similarly, the floor slab [3] with the periphery processed with the lower steps [19] can also be used in all use environments and conditions, and is convenient for the installation and fixation of waterproof coiled materials, guide plates, prefabricated members and guide plates.
In order to reduce the weight of the waterproof board, a cavity [18] can be processed at a proper position of the waterproof board.
With reference to fig. 7, in this embodiment, a non-wetting sheet or a non-wetting coil [10] with a suitable width and a non-wetting surface may also be installed between the floor slab [3] and the vibration/noise reduction pad [4], and a surface of the periphery of the rear surface of the floor slab [3] that is consistent with or wider than the contact surface of the non-wetting sheet or the non-wetting coil [10] is processed into the non-wetting surface, or more surfaces of the floor slab [3] are processed into the non-wetting surface; the side edge of the floor slab [3] is tightly attached or pressed on the non-infiltration plate or the non-infiltration coiled material [10] to ensure that the two non-infiltration surfaces are tightly attached to prevent water leakage, a single hydrophilic or hydrophilic and non-infiltration combined drainage piece [11] is arranged or installed on the outer side of the non-infiltration plate or the non-infiltration coiled material [10], namely the surface of the water outlet side and extends into a drainage system, and a small amount of leaked water between the non-infiltration surfaces of the floor slab [3] and the non-infiltration plate or the non-infiltration coiled material [10] is drained to the drainage system by the drainage piece [11] to form a blocking and guiding type surface energy waterproof system to complete a waterproof task.
Example 2: with reference to fig. 4, on the basis of embodiment 1, the floor slab [3] and the vibration and noise reduction layer [2], or the floor slab [3], the vibration and noise reduction layer [2] and the protection layer [1] are processed into an integral combined vibration and noise reduction floor slab, which facilitates construction and improves working efficiency.
With reference to fig. 5, in this embodiment, a waterproof layer may be further added on the outer surface or the upper surface of the combined vibration-damping noise-reduction floor slab, or the combined vibration-damping noise-reduction floor slab is processed by using a material with waterproof performance, so that the combined vibration-damping noise-reduction floor slab has a waterproof function, and is convenient for construction and installation of waterproof engineering.
In the embodiment, when the upper surface of the combined vibration-damping noise-reducing floor slab has waterproof performance, the drainage ditches [17] can be processed at two sides or the periphery of the combined vibration-damping noise-reducing floor slab, so that the fall of the downpipe is larger, and the drainage effect is better.

Example 3: with reference to fig. 10, on the basis of the above embodiment, more than one sound insulation layer [20] hermetically connected with the bearing beam or the bearing wall [5] is arranged below the floor [3] at a proper distance, so that the floor [3] and the lower layer space form an effective sound insulation space, the transmission of noise is reduced or blocked, and the sound insulation effect is improved. At the moment, the vibration and noise reduction layer [2] with the vibration and noise reduction and sound absorption functions and corresponding auxiliary arrangement on the floor slab [3] in the embodiment can be omitted according to specific conditions, so that the vibration and noise reduction engineering structure is simpler, and the construction is more convenient. And a vibration and noise reduction gasket [4] can be arranged between the sound insulation layer [20] and the bearing beam or the bearing wall [5] to further reduce or block the transmission of noise.
With reference to fig. 11, in this embodiment, the sound insulation layer [20] and the support beam [8] can be processed into a whole to be used as a combined sound insulation board, so that on one hand, the mechanical structure performance of the sound insulation layer [20] is improved, or the thickness of the sound insulation layer [20] is reduced, and on the other hand, the sound insulation layer can provide proper supporting force for the floor slab [3], and the requirement on the mechanical structure of the floor slab [3] is reduced. When the integral structure of the sound insulation layer [20] and the supporting beam [8], namely the combined sound insulation board, has bearing capacity, the floor slab [3] can be split into a plurality of (more than two) split floor slabs with proper sizes and then is installed on the supporting beam [8] provided with the vibration and noise reduction gasket [4], or a plurality of floor slabs [3] which have the same distance with the bearing beam or the bearing wall [5] are installed on the supporting beam [8] or the bearing beam or the bearing wall [5] which has bearing task and is provided with the vibration and noise reduction gasket [4], so that the weight of a single floor slab is reduced, and the construction difficulty is reduced.

Or the support beam [8] and the floor slab [3] are processed into an integral composite floor slab to reduce the requirement on the mechanical structure of the floor slab [3], and then the sound insulation layer [20] and the support beam [8] are fixed by a proper connecting method (at the moment, a vibration-damping noise-reducing gasket [4] is added between the sound insulation layer [20] and the support beam [8 ]).
Furthermore, in the embodiment, a plurality of sound insulation layers [20] and the support beam [8] can be processed into an integral combined sound insulation layer which is spliced together and then hermetically connected to replace the integral sound insulation layer [20], or a plurality of single T-shaped, double T-shaped or multi-T-shaped plates (namely more than three ribs) which are reversely arranged (namely a flat plate is arranged below and the ribs are arranged above) are spliced together and then hermetically connected to replace the integral sound insulation layer [20], and then a floor slab [3] and a sound insulation facility are arranged above, so that the construction difficulty is reduced; or a plurality of floor slabs [3] and the support beam [8] are processed into an integral composite floor slab and then are spliced together by a proper method to replace the integral floor slab [3], or a plurality of single T-shaped, double T-shaped or multi-T-shaped plates (namely more than three convex edges) are spliced together by a proper method to replace the integral floor slab [3], and then a sound insulation layer [20] and a sound insulation facility are arranged below the floor slab to reduce the construction difficulty.

In this case, the sound insulation and noise reduction layer [21] can be an existing sound absorption material, and can also be a multi-bubble inflation cushion layer with better mechanical property. In this case, loose materials such as fine sand, soil, porous materials or sound insulating materials can be directly filled in the sound insulating layer (20) to serve as a sound absorbing layer, so that the downward transmission of vibration or noise above the sound insulating layer (20) to the sound insulating layer (20) can be reduced or blocked.
