[0050] The first baffle plate 2, the plurality of drainage grooves 3 and the second baffle plate 4 are overlapped in sequence to form a water collecting groove 6 with an upper opening;

[0051] A plurality of connection frames are arranged at intervals in the water collecting tank 6, and hanging points are symmetrically arranged on the plurality of connection frames;

[0061] In one embodiment, the first lap plate 21 and the second lap plate 31 are both provided with an adhesive layer, so that the plurality of drainage grooves 3 and the first baffle plate 2 and the second baffle plate 4 and the water collecting groove 6 can be tightly overlapped.

[0062] In a specific embodiment, the bonding layer is formed by coating the first lap plate 21 and the second lap plate 31 with asphalt waterproof coating.

[0071] In one embodiment, the inside of the butterfly buckle is provided with an internal thread that is compatible with the bolt, so that the butterfly buckle can move relative to the bolt. It is used to adjust the distance between a plurality of grate covers and the water collection tank, as well as the setting slope of the water collection tank.

When it is necessary to adjust the setting slope of the water collection tank, the butterfly buckle on the single-sided hanging point can be adjusted so that there is a difference in the height of the hanging points on both sides of the water collection tank, so that the water collection tank can be tilted to one side to adjust the setting slope of the water collection tank.

[0072] In one embodiment, the water collecting trough 6 is arranged to be parallel to the grate cover plate 1 .

[0073] In another embodiment, the sump 6 is arranged to be inclined toward the direction of the plurality of drainage pipe assemblies with a slope of 5%.

[0074] In one embodiment, the drain pipe assembly includes a first drain pipe 10 and a second drain pipe 11. The first drain pipe 10 is arranged at a distance at the lower end of the sump 6. The second drain pipe 11 is sleeved on the first drain pipe 10, and the lower end is connected to the sump. Specifically, the sump is set at the bottom of the basement for collecting water flow. The first drain pipe is welded to the lower end of the sump and is connected to the sump so that the water flow in the sump can flow downward through the first drain pipe and then flow into the sump through the second drain pipe for collection, so as to avoid excessive water flow in the sump, resulting in leakage, and can achieve the effect of organized drainage into the basement. In a specific embodiment, the interval between the first drain pipe 10 on the sump 6 is less than or equal to 20 mm, and the diameter and length of the first drain pipe 10 are both greater than or equal to 100 mm. Specifically, the diameter of the lower end of the first drain pipe is smaller than the diameter of the upper end, so as to facilitate the connection of the second drain pipe.

[0075] When the drainage structure of the utility model is used, a plurality of grate cover plates can be laid on the through ribs in the post-casting belt in the basement top plate, and then the tension connectors are symmetrically hung on the grate cover plates at a specified distance, and then a plurality of connection frames are welded to the inside of the drainage trough at a specified interval, and the drainage trough is hung on the upper end of the tension connector by using the hanging points on the plurality of connection frames, and the setting height or setting slope of the drainage trough is adjusted by using the tension connector, and then the adhesive layer is applied on the second overlap plate of the drainage trough, and then the drainage trough is adjusted according to the height of the post-casting belt.
