Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In this embodiment, the sound insulation layer 3, the thermal insulation layer 4, the first waterproof layer 5 and the waterproof membrane 6 are all placed inside the groove 2, and then blocked by the waterproof membrane 6. A first waterproof layer 5 is arranged under the waterproof membrane 6 to prevent water leakage. The thermal insulation layer 4 is composed of a plurality of groups of extruded polystyrene boards spliced ​​together to provide insulation. The joints between two adjacent groups of thermal insulation layers 4 are bonded and sealed with waterproof self-adhesive asphalt 11, which is not prone to water seepage and leakage. After the reinforced concrete layer 7 is poured, the second waterproof layer 8 is applied to further improve the waterproof effect. Then the floor layer 9 is laid, and the skirting board 10 is laid at the joint between the floor layer 9 and the wall. Then, the joint between the floor layer 9 and the skirting board 10 is sealed with sealant. Compared with the prior art, the waterproof effect is better, which helps to improve the service life of the floating floor.

[0019] Please refer to Figure 1 As shown, the sound insulation layer 3 is specifically 5 mm thick sound insulation cotton and is laid along the groove wall of the groove 2. The waterproof membrane 6 is specifically 1 mm thick polyethylene film. The reinforced concrete layer 7 is cast with concrete of strength grade C20. The floor layer 9 can be paved with ceramic tiles or wooden floors.

[0020] In this embodiment, 5mm sound insulation cotton 3 is laid along the groove wall of the entire groove to form a cover shape. Compared with the method of only laying on the ground, the sound insulation effect is better, and the sound insulation effect of the floating floor can be improved. The extruded polystyrene board of the insulation layer 4 is a thermal insulation material made of polystyrene resin supplemented with polymers, and has an independent closed bubble structure. This structure makes it have excellent properties such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, and low thermal conductivity. Due to these characteristics, the extruded polystyrene board can provide sound insulation to a certain extent. The material density of the extruded polystyrene board is relatively high. This high-density structure can effectively reduce the propagation of sound waves, so It has good sound insulation effect. The cell structure of the extruded benzene board is closed, and there is no pore inside that communicates with the outside world. This closed cell structure can hinder the propagation of sound waves, thereby providing a certain sound insulation effect. Increasing the thickness of the extruded benzene board can also improve the sound insulation effect. Thicker extruded benzene boards can better absorb and reduce the propagation of sound waves. Polyethylene waterproof membrane 6 is a polymer material polymer, commonly known as HDPE anti-seepage membrane or HDPE anti-seepage geomembrane, a plastic waterproof membrane composed of HDPE epoxy resin, in which HDPE is a thermoplastic plastic with high grain size and non-polarity. Polyethylene waterproof membrane has the following characteristics:

[0021] Good waterproof performance: It can effectively prevent moisture penetration and ensure the waterproof effect.

[0022] Good chemical stability: Polyethylene material can withstand corrosion from most chemicals and can therefore be used in a variety of environments.

[0023] High mechanical strength: It has high rigidity and toughness, as well as good mechanical strength.

[0024] Good temperature resistance: Polyethylene waterproof membrane has good high and low temperature resistance, with a melting point of approximately 110℃~130℃, and can be used in a wide temperature range.

[0025] Good environmental stress cracking and tear resistance: As density increases, its mechanical and barrier properties also improve.

[0026] Good environmental performance: Polyethylene material is a thermoplastic resin, does not contain harmful substances, and has environmental protection performance.

[0027] The reinforced concrete layer 7 is cast with concrete of strength grade C20 and steel bars to meet the requirements of floor bearing capacity and durability. The floor layer 9 can be made of ceramic tiles or wooden flooring according to needs.
