The arc-shaped water baffles 13 are inclined from the outside to the inside and smoothly connected with the water inlet 100. The arc-shaped water baffles 13 can reduce the impact force of the water flow, concentrate the water, and increase the water inlet speed at the water inlet 100.

[0029] Reference Figure 3 and Figure 4 A plurality of reinforcing rings 14 are evenly fixedly connected to the outer wall of the groove body 10 along the extension direction of the groove body 10. The bottom end of the reinforcing ring 14 is fixedly connected to the middle lap edge 12. The plane where the reinforcing ring 14 is located is perpendicular to the extension direction of the groove body 10. A connecting rib 15 is fixedly connected between two adjacent reinforcing rings 14 and the outer wall of the groove body 10. The connecting rib 15 and the reinforcing ring 14 are perpendicular to each other.

[0030] Reference Figure 1 , two adjacent drainage grooves 1 are connected by a corner connector 2, and the corner connector 2 includes a three-way and a four-way structure. In this embodiment, the four-way structure is taken as an example. The three-way structure is used at the turning point, and the four-way structure is used for the wide surface. A clamping plate 20 is provided at the end of the corner connector 2, and a clamping groove is provided at the end of the drainage groove 1. The connection between the corner connector 2 and the drainage groove 1 is achieved by the cooperation of the clamping plate 20 and the clamping groove. When connecting, it is necessary to pay attention to whether the clamping part is complete to form a sealed space. Waterproof coating is scraped under the drainage groove 1 and the corner connector 2 to fix them. The joint is required to be airtight to make it non-breathable, so as to form a stable drainage space.

The ventilation observation pipe 5 is vertically arranged and connected to a water reservoir 6 at the bottom. Rainwater output by the drainage trough 1, the drainage pipe 4 and the ventilation observation pipe 5 flows into the water reservoir 6. A ventilation rainwater cover 7 is installed on the top of the ventilation observation pipe 5 and the drainage vent pipe 3.

[0032] Reference Figure 1 and Figure 5The top surface of the roof is paved with a polymer protective drainage shaped sheet 8, and a plurality of shaped convex points 80 are fixedly connected to the top surface of the polymer protective drainage shaped sheet 8 in a matrix.

[0034] The drainage pipe 4 is connected to the water reservoir 6 from the water inlet 100. The water reservoir 6 is composed of a rainwater cover above and a cushion layer is poured in advance below. After the sewage in the water reservoir 6 is precipitated, it is discharged into the municipal rainwater system. Before the polymer protective drainage special-shaped sheet 8 is laid, the position of the air permeable observation tube 5 is marked on the drawing, and the positioning and laying out are carried out according to the position on the drawing. After completion, the air permeable observation tube 5 is installed according to the laying out position.
