[0030] The utility model is further described below with reference to the accompanying drawings and specific embodiments.
[0031] like Figure 1-Figure 2 As shown, this embodiment provides an assembled decoration floor drainage structure, including a floor, a floor drain 10 and a waterproof tray 20. The floor includes a panel layer 21, a PVC layer 22, a waterproof layer 23 and a support layer 24 arranged in sequence from top to bottom. The floor drain 10 includes a floor drain body 25 and a first cover plate 26 arranged on the top of the floor drain body 25. A first through hole is opened at the center of the first cover plate 26. The floor drain body 25 includes a connecting pipe 28 and a water outlet pipe 29 that are integrally connected and coaxially arranged. The connecting pipe 28 is located at the top of the drain body 25. Above the water outlet pipe 29, the connecting pipe 28 is connected to the water outlet pipe 29. The aperture of the connecting pipe 28 is larger than the aperture of the water outlet pipe 29. The water outlet pipe 29 passes through the panel layer 21, the PVC layer 22, the waterproof layer 23 and the support layer 24 in sequence.

The honeycomb panel 12 has the characteristics of light weight, high strength and high rigidity, which can reduce the overall weight of the floor and improve its strength.
[0032] A check valve 27 is provided in the floor drain body 25, and the waterproof tray 20 is detachably mounted on the outlet pipe 29, and the waterproof tray 29 and the outlet pipe 29 are coaxially arranged, and the waterproof tray 29 is located below the waterproof layer 23, and the waterproof tray 29 includes a bottom plate 30 and a side plate 31, the side plate 31 is arranged around the bottom plate 30, the side plate 3 is arranged vertically, and the lower end of the side plate 31 is integrally connected to the periphery of the bottom plate 30, the bottom plate 30, the outlet pipe 29 and the side plate 31 together form a accommodating space, the outer peripheral wall of the outlet pipe 29 is provided with an external thread section (not shown in the figure), and the bottom plate 30 is provided with a mounting hole (not shown in the figure) for the outlet pipe 29 to pass through, and the inner side wall of the mounting hole is provided with an internal thread section matching the external thread section, and the waterproof tray 20 and the outlet pipe 29 are threaded by the external thread section and the internal thread section. The bottom plate 30 is provided with a sealing ring 38, and the inner wall of the sealing ring 38 is tightly matched with the outer wall of the water outlet pipe 29, and the outer wall of the sealing ring 38 is tightly matched with the side of the side plate 31 facing the mounting hole. The outer wall of the water outlet pipe 29 is provided with a first drainage hole 32 that connects the accommodating space and the inner cavity of the water outlet pipe 29. The horizontal height of the sealing ring 38 is lower than the horizontal height of the first drainage hole 32, and the distance between the first drainage hole 32 and the bottom plate 30 is smaller than the height of the side plate 31. By providing a waterproof tray 29, the ground water that penetrates under the tiles will fall on the waterproof tray 29. When the water level of the ground water in the waterproof tray 29 rises to the position of the first drainage hole 32, the ground water in the waterproof tray 29 overflows and flows into the water outlet pipe 29 for drainage.
[0033] The first cover plate is further provided with a plurality of second through holes, which are distributed around the axis of the first through hole. By providing the first through holes and the second through holes on the first cover plate 26, hair, paper towels and other debris can be effectively prevented from entering the connecting pipe 28, thereby reducing blockage.
