Background

With the increasing development of society, the shortage of water resources becomes an important factor for restricting the development of cities in China. The increase of urban population leads to the increase of urban total water consumption, breaks the balance condition of water resource balance supply and demand, and effectively utilizes rainwater resources to relieve the problem of water resources to a certain extent. Through scientific management, rainwater not only can be used as an effective resource, but also can be combined with landscape design to generate certain economic benefit and ecological benefit. Rainwater collection and utilization in China start late, and the landscape design angle is much less. Usually, roof rainwater occupies a large part of rainwater collection resources, and compared with rainwater from other sources, the roof rainwater has cleaner water quality and is more beneficial to filtering and utilizing. Generally, the waste water is collected, filtered and then recycled to a water collecting tank for secondary use. However, the filtration system combining natural ecological function and manual intervention function is more advocated at present, for example, a penetration system consisting of an infiltration tank, an infiltration well, a grassland and a permeable ground is built in the United states.

Detailed Description

The present invention will be further described with reference to the following examples.

This embodiment vestibule setting belongs to open vestibule in the park, and concrete structure is as follows: the corridor top 1 is made of toughened laminated glass and has a certain gradient of 0.5% for facilitating rain collection.

A catchment rain gutter 2 is arranged on the outer side of the corridor top 1, and a rain baffle is arranged on the outer side of the gutter to reduce rain loss. When raining, the rainwater flows into the catchment rain channel 2 along the slope. The bottom of the catchment rain gutter 2 is provided with a rain opening 3 at intervals, the approximate diameter of the vertical pipe can be calculated according to a rainstorm intensity formula and related local parameters, a proper drainage vertical pipe 4 is selected, and rainwater in the catchment rain gutter 2 enters the drainage vertical pipe 4 through the rain opening 3.

For the aesthetic appearance of the park, the drainage risers 4 are housed in hollow uprights 5. The lower end of the vertical drainage pipe 4 is designed into a bent pipe and is communicated to a green belt 6 on one side, and rainwater flows out in a free outflow mode and seeps into the ecological filter ditch together with rainfall. The ecological filter ditch is arranged below the green belt 6 and is divided into a planting soil layer 7, a sand layer 8, a gravel layer 9 and an impermeable layer 10 from top to bottom. In order to ensure the nutrients required by plants in the green belt 6, the filling height of the planting soil layer 7 is 50cm, and the planting soil layer consists of 2:1 proportion of wormcast and rural soil. The sand layer 8 has a filling height of 30cm and is composed of quartz sand with a particle size of 0.5-1.2 mm.

The gravel layer 9 is laid in four layers, different gravels with the grain diameter of 2-4mm, 4-8mm, 8-16mm and 16-32mm are laid from top to bottom, and the height of each layer is 10 cm. In order to improve the rainwater collection efficiency, a geomembrane is paved on the periphery of the ecological filter ditch. In order to avoid the gravel blocking the orifices, the perforated conduit 11 is embedded in a gravel layer 9 with a particle size of 16-32 mm. The perforated conduit 11 is made of PVC, the aperture is 9-12mm, the holes and the vertical line form a 45-degree angle downward, and the holes on the two sides of the vertical line are arranged in a staggered manner. The number and the spacing of the holes are determined according to the opening ratio which is 0.2 to 0.28 percent. In order to balance the pressure of the pipeline, the equal spacing of the orifices and uniform distribution are ensured.

The rainwater is filtered by each layer, flows out of the gravel layer 9 and enters the perforated pipe 11 along the opening of the perforated pipe 11. If the impermeable barrier 10 is in close proximity to the reservoir 12, the water in the perforated conduit 11 flows directly into the reservoir 12, and if there is a space between the impermeable barrier 10 and the reservoir 12, there is a conduit communication between the perforated conduit 11 and the reservoir. The reservoir 12 is a weldless stainless steel fabricated tank built underground at the corner of the park. A water pump 13 is arranged outside the reservoir 12, the water pump 13 is connected with a solar street lamp 14, the water pump 13 is powered by solar power generation, and an ultraviolet disinfection device 15 is arranged in a water outlet pipeline of the water pump 13 and can disinfect and sterilize water flow. The collected rainwater after treatment can be used for spraying road surfaces or irrigating green belts.
