Description

Elevated road rainwater collection, treatment, storage and utilization system

technical field

The invention relates to the technical field of drainage, in particular to an elevated road rainwater collection, processing, storage and utilization system.

Background technique

The level of urbanization in China is getting higher and higher, and the phenomenon of water shortage in cities is becoming more and more serious, which seriously affects the sustainable development of cities. Therefore, it is very important to implement rainwater collection, treatment, storage and utilization. Making full use of the treated rainwater can save a lot of urban tap water and achieve environmental and economic benefits of energy saving and emission reduction.

However, the initial rainwater of urban roads contains a large amount of pollutants, which will cause serious pollution and damage to the local environment. If it is allowed to discharge freely, it will cause serious pollution to rivers, groundwater, farmland, etc., and it is difficult for impermeable surfaces to quickly drain rainwater into the ground. Therefore, to use rainwater, it is necessary to do a good job in rainwater treatment.

Most of the existing rainwater treatment systems lead rainwater to several rainwater treatment facilities concentrated in the city for treatment. Use the environment. This results in low efficiency of rainwater treatment and high cost of use, which is also the main reason why the application of rainwater treatment is difficult to promote at present.

In addition, due to space and environmental constraints in cities, it is difficult to disperse and install large-capacity rainwater storage devices. Therefore, those skilled in the art are devoting themselves to developing a rainwater collection, treatment, storage and utilization system for elevated roads that occupies less land, is multifunctional and efficient.

The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

Description of drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is another structural schematic diagram of the embodiment of the present invention.

Detailed ways

As shown in Fig. 1 and Fig. 2, a specific embodiment of the elevated road rainwater collection, processing, storage and utilization system of the present invention includes a plurality of rainwater outlets 1 (only one is shown in the figure) arranged on both sides of the elevated road.

The first outlet of the rainwater outlet 1 directly connects with the rainwater well 15 through the initial overflow pipe 11 . The second outlet of the gully 1 passes through the primary rainwater filter 12 , the secondary rainwater filter 13 , the rainwater treatment device 14 and the rainwater storage device 16 in sequence. The rainwater storage device 16 is installed underground and has a water intake 161 .

One function of the initial overflow pipe 11 is to directly discharge the heavily polluted initial rainwater on the elevated road into the rainwater well 15 when the rainwater treatment device 14 is closed by human control. At this time, the initial rainwater does not enter the rainwater storage device 16 . After the initial rainwater passes, the rainwater treatment device 14 is manually controlled to open, and the later rainwater mainly enters the rainwater storage device 16 through the second outlet of the rainwater outlet 1 . Therefore, a function of the present invention is to ensure that the rainwater collection, processing, storage and utilization system can discard the initial rainwater and only collect later rainwater through the normal opening control of the rainwater treatment device 14 .

Another function of the initial overflow pipe 11 is that when the rainwater treatment device 14 breaks down, all rainwater can be directly discharged into the rainwater well 15 .

In this embodiment, the elevated road rainwater collection, processing, storage and utilization system includes five sets of rainwater storage devices 16 that communicate with each other. In particular, as shown in FIG. 1 , one group of rainwater storage devices 16 respectively communicates with the other four groups of rainwater storage devices 16 . need.

In this embodiment, the rainwater primary filter 12 is a particle filter, which is mainly used to filter small stones, leaves, cigarette butts, plastic bags, paper and other sundries in the rainwater.

The rainwater secondary filter 13 is a filament filter, which is mainly used to filter filaments such as hair in rainwater.

The rainwater storage device 16 is a high-strength composite material with strong compression resistance and long service life. The number of groups can be adjusted according to volume requirements, and the construction is convenient. The rainwater storage device 16 is arranged underground and occupies less land. It is especially ecological and environmentally friendly when combined with green land. It also has an overflow port 162 and a mud discharge port 163 .

A special design of the present invention is that the mud discharge port 163 is arranged on the end of the rainwater storage device 16 arranged horizontally in FIG. 1 away from the water inlet pipe. The beneficial effect of such an arrangement is that after the rainwater enters the rainwater storage device 16, a small amount of suspended silt therein is impacted to the end away from the water inlet pipe. Even if a small amount of silt settles near the water inlet pipe, when water enters again, this part of silt will be washed to the far end. Therefore, the far end of the horizontally arranged rainwater storage device away from the water inlet pipe is the area where the most suspended sediment is deposited.

When the rainstorm exceeds the total storage capacity of the rainwater storage device 16, the rainwater can be discharged into the river through the overflow port 162, or directly discharged into the municipal pipeline nearby.

The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art shall be within the scope of protection defined by the claims.
