Specifically, this embodiment provides a trench structure, which is arranged in an indoor foundation layer 1 (specifically built on the indoor foundation layer 1), and the trench structure includes an anti-leakage layer 2, a trench inner layer 3 and a trench surface layer 4. The anti-leakage layer 2 is arranged in the indoor foundation layer 1; the trench inner layer 3 is arranged on the anti-leakage layer 2, and the bottom surface of the trench inner layer 3 is an arc-shaped curved surface; the trench surface layer 4 is attached to the trench inner layer 3. It should be noted that the trench inner layer 3 includes a first vertical surface 301, a concave arc surface 302 and a second vertical surface 303 arranged in sequence, and the heights of the first vertical surface 301 and the second vertical surface 303 are both h, and the arc surface 302 is specifically a semicircular curved surface with a radius of r. The radius r of the semicircular curved surface, the height h of the first vertical surface 301 and the height h of the second vertical surface 303 can be set according to actual needs, and are not limited in this embodiment.

[0028] The indoor foundation layer 1 belongs to the basic structure of the indoor floor, and the material, compaction, flatness and slope of the indoor foundation layer 1 can be set according to actual drainage needs.

[0029] The anti-leakage layer 2 comprises a concrete layer, and the anti-leakage grade of the anti-leakage layer 2 is >P8.

[0030] The inner layer 3 of the trench includes a cement mortar layer, which is used to fix and support the trench surface layer 4 and also has a certain waterproof function.

[0031] The thickness of the trench surface layer 4 is greater than 2 mm, and the trench surface layer 4 includes a polyurethane mortar layer. The material of the polyurethane mortar layer belongs to the prior art. Since the polyurethane mortar material has excellent properties such as high strength, high temperature impact resistance and strong chemical corrosion resistance, it becomes a good manufacturing material for the trench surface layer 4. Of course, it should be understood that the trench surface layer 4 can also be a stainless steel surface layer, which is not limited in this embodiment.

[0032] As a preferred implementation of this embodiment, steps are provided on both side walls of the anti-leakage layer 2, and the steps are arranged along the length direction of the anti-leakage layer 2. The surface of the steps includes a first step surface 201, a second step surface 202, and a third step surface 203 arranged in sequence, the first step surface 201 and the third step surface 203 are arranged in the horizontal direction, and the first step surface 201 is located above the third step surface 203; the second step surface 202 is arranged in the vertical direction, and one end of the second step surface 202 is connected to the first step surface 201, and the other end is connected to the third step surface 203.

[0033] A trench cover 5 is provided between the two steps, and the lower surface of the trench cover 5 is in contact with the third step surface 203; the top of the trench inner layer 3 and the top of the trench surface layer 4 are both in contact with the lower surface of the trench cover 5. The trench cover 5 is used to cover the top of the trench structure to prevent indoor personnel from accidentally falling into the trench structure when the trench structure is not in use, causing serious safety accidents. The end of the trench cover 5 is in contact with the second step surface 202; the upper surface of the trench cover 5 is flush with the first step surface 201, so that the trench structure has better flatness.

[0034] Specifically, the trench structure provided in this embodiment has at least the following beneficial effects:

[0035] (1) By setting the bottom surface of the inner layer 3 of the trench as an arc-shaped surface, it is beneficial for pollutants such as oil attached to the side wall of the trench surface layer 4 to slide down to the bottom of the trench surface layer 4 and be discharged along the flowing water, thereby improving the drainage effect of pollutants on the side wall of the trench, achieving effective removal of pollutants on the side wall of the trench, and preventing the trench from generating odor and polluting the air in the indoor environment;

[0036] (2) The trench cover 5 is arranged at the top of the trench inner layer 3 and the top of the trench surface layer 4 to cover the top of the trench structure. When the trench structure is not in use, it prevents indoor personnel from accidentally falling into the trench structure and causing serious safety accidents.

[0037] The present application provides a trench structure, which is arranged in an indoor foundation layer 1, and the trench structure includes an anti-leakage layer 2, a trench inner layer 3 and a trench surface layer 4.
