The technical scheme in the embodiment of the utility model will be clearly and completely described with the attached drawings. Obviously, the described embodiment is only a part of the embodiment of the utility model, not the whole embodiment. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in the field without creative labor belong to the protection scope of the utility model.
Please refer to Figure 1.

Between the multilayer board 10 and the bottom high-density polyurethane sound insulation board 1 1, the bottom rubber particle sound insulation board 13 is set with a thickness of 3mm, which increases the bottom high-density polyurethane sound insulation board1/kloc-.
A sound insulation interlayer 14 is arranged between the bottom high-density polyurethane sound insulation board 1 1 and the concrete layer 12, and the sound insulation interlayer 14 includes a bottom rubber particle sound insulation pad and a bottom rubber sound insulation felt to increase the bottom high-density polyurethane sound insulation board1/kloc-0.
The thickness of rubber particle isolation pad and rubber sound insulation felt at the bottom is 3 mm and 2 mm respectively, so the thickness should be limited to avoid the influence of excessive thickness on the later installation and actual use effect;
The thickness of concrete layer 12 is set to 50 mm, and the weight of concrete layer 12 is limited by the thickness, so as to avoid structural deformation at the bottom due to excessive extrusion of concrete layer 12.
Working principle: between the top surface of subbase 1 and concrete layer 12, there are bottom rubber particle isolation pads 8, bottom high-density polyurethane sound insulation board 1 1, bottom rubber particle isolation pads I 13 and sound insulation interlayer 14. Because the rubber and PVC are the main materials of the bottom rubber particle isolation pad 8, the bottom rubber particle isolation pad-13 and the sound insulation interlayer 14, they have good sound absorption and silencing functions, and the sound insulation effect is good through these interlayers. On the right side of the side wall 2, a side rubber particle isolation pad 3, an inner high-density polyurethane sound insulation board 5, an outer high-density polyurethane sound insulation board 6, a rubber sound insulation sandwich felt 7 and a rubber sound insulation felt 70 1 are arranged, all of which are made of rubber and PVC and have good sound absorption and noise reduction functions.
