In order to implement a sponge city, a roof drainage system is widely used on a roof, particularly a planted roof, and can collect rainwater, irrigation water and the like falling on the roof and then discharge the rainwater to the underground or store the rainwater in an underground reservoir through a pipeline. The system mainly comprises drain plates laid on a roof, a drain groove and a drain groove joint, wherein the drain groove is connected into a net through the drain groove joint and is interwoven between the tiled drain plates. After the roof drainage system is laid, a geotextile is usually covered above the roof drainage system, and soil layers such as green soil and the like are backfilled. During rainfall or irrigation, water in soil passes through the geotextile and enters the drainage plate, then flows into the drainage groove through the drainage ports on two sides of the drainage groove, and finally enters the reservoir from the drainage groove.

The shape of the first partition 130 may be various, such as a flat plate (see fig. 3), an arc plate (see fig. 4), and the like.

The water absorbing cover 230 of the embodiment is arranged in the water absorbing cavity 210, when the converging cavity 110 is filled with water, the water gathered from the water inlets 111 overflows into the water absorbing cavity 210, and simultaneously fills the gap gradually until the water level in the water absorbing cavity 210 can continuously rise when the water absorbing pipe 220 plays a role of absorbing water, the water absorbing function of the water absorbing pipe 220 also enables the water in the water absorbing cavity 210 to be rapidly absorbed, and the passing speed of the water flow at the joint of the water drainage tank is ensured. Preferably, the height of the water suction cavity 210 is 2 to 3 times of the height of the confluence cavity 110.

Generally, the diameter and gap width of the suction pipe 220 need to be designed to be small, which will limit the passing speed of water flow to some extent, for this purpose, as shown in fig. 5, a second partition 240 with a through hole 241 is provided between the suction chamber 210 and the confluence chamber 110, and the top of the second partition 240 is provided with a suction cylinder 242 with an upward opening; the water suction cylinder 242 is sleeved outside the water suction pipe 220 and inserted into the gap, and divides the gap into a first gap 221 and a second gap 222, the first gap 221 is located between the outer surface of the water suction cylinder 242 and the inner surface of the water suction cover 230, the second gap 222 is located between the inner surface of the water suction cylinder 242 and the outer surface of the water suction pipe 220, and the opening end surface of the water suction cylinder 242 is higher than the top end of the water suction pipe 220.
