Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] As shown in the figure, an initial waste water outlet for sponge city construction includes a rainwater well 2, a flat grate rainwater outlet 1, a self-floating rising rainwater outlet sealing device 3, a sealing device floating track 7, and a vertical grate rainwater outlet 6. The initial rainwater outlet pipe 4 and the slow-release device 5 are characterized in that:

[0020] The self-floating rising gully sealing device 3 is made of a low-density weather-resistant material with a density lower than that of water. The side rectangular block 32 and the vertical rod 33 of the self-floating rising gully sealing device connected to the upper rectangular block 31 of the self-floating rising gully sealing device and the upper rectangular block 32 of the self-floating rising gully sealing device, After the rainwater enters the rainwater well, it floats up until th...

Abstract

The invention discloses an initial-stage flow-abandoning gutter inlet for sponge city construction. An initial-stage rainwater outlet pipe is arranged at the lower part of a rainwater well, a self-floating rising type gutter inlet sealing device is arranged in the rainwater well, the self-floating rising type gutter inlet sealing device is made of a light high-durability material with the densitysmaller than that of water, and a flat grate gutter inlet is blocked when the self-floating rising type gutter inlet sealing device floats upwards to the flat grate gutter inlet; and a vertical grategutter inlet is formed in the side part above the rainwater well, a concave green land or a biological retention facility is arranged on the outer side of the vertical grate gutter inlet, after rainwater enters the rainwater well, the self-floating rising type gutter inlet sealing device floats upwards until the flat grate gutter inlet is blocked, and the rainwater stops entering the rainwater well and enters the concave green land or the biological retention facility through the vertical grate gutter inlet. The device can effectively solve the problems that when rainwater on roads for spongecity construction needs to be discharged into source emission reduction facilities such as the concave green land or the biological retention facility, the initial-stage rainwater pollution degree ishigh, plant death is easily caused, and maintenance in the green land is difficult.

Description

technical field [0001] The invention relates to the field of sponge city construction, in particular to the design of a stormwater outlet for directly discharging road rainwater into green belts, in particular to a stormwater outlet for initial waste flow used in sponge city construction. Background technique [0002] In recent years, with the strong support of the state and local governments, the construction of sponge cities has advanced rapidly. Sponge city construction, as an important measure of new urbanization, advocates the reduction of rainwater discharge at the source, and realizes the source control, consumption and utilization of rainwater through the "seepage, storage, stagnation, net use and discharge" of source facilities. The area where the storage and stagnation function is realized is the largest. The road system needs to ensure the safety of vehicles and the stability and durability of the road structure, so the ability to store and stagnate rainwater is l...
