Description

Rainwater retention system

The present invention relates to a rainwater storage system, and more particularly to a rainwater storage system that utilizes the concept of storm management in land development operations.

As the global climate instability becomes more apparent, regional rainfall estimates are increasingly difficult to estimate from past averages or peak records. Coupled with the highly intensive development of the city, the culvert function of the surface is greatly reduced. Once a heavy rainstorm occurs in a short period of time, the unit rainfall exceeds the drainage load of the designed rainwater and underwater waterway system in the area, which will cause serious water accumulation in the urban area, which will affect the safety of people and vehicles and even the loss of housing property. Therefore, especially in urban areas, the issue of stormwater management has become more and more important in urban development planning.

The concept of stormwater management is to drain and store some of the lowered rainwater so that it will not be directly poured into the rainwater and underwater waterway system to reduce the drainage load of the rainwater and underwater waterway system by the high rainfall dropped in a short period of time. This mechanism of reducing the amount of heavy rainfall directly into the rainwater channel is seen as a means of urban sustainable development, also known as Low Impact Development.

The traditional stormwater rainwater retention system directs the descending rainwater from the rainwater channel to the wetland or pond, and soothes the rainstorm by transporting water to the wetland/lake pond and the catchment function of the wetland/lake pond. The test and impact of the maximum amount of flooding on rainwater and underwater waterways. The concept of this approach is rapid drainage, so that the amount of water in the rainwater and underwater waterway system can be relieved without flooding to the surface. However, in terms of the height of urban planning, the above method requires not only a considerable area of wetland/lake pond, but Rainwater has not been further utilized in the process of grooming. In the future, if you want to use the catchment of wetlands/lakes, for example, as a green and beautiful irrigation water, it will take additional procedures and power to achieve.

In view of this, the development of a new rainwater storage system can integrate the functions of water collection, regulation and culvert media to achieve the replenishment of shallow groundwater, and delay the rainwater into the rainwater channel, thereby reducing the peak load of the regional drainage system. It is a subject worthy of attention in the industry.

Because of the difference in height between the openings, when the rainwater introduced into the adjusting device from the first joint 220 accumulates to the first water level, higher than the lower edge of the third joint 260, the water stored in the adjusting device will be first The triple joint 260 is channeled to a second conduit in the permeable belt. When the water storage in the adjusting device continues to increase to the second water level, the second water level refers to a lower edge of the first opening 242 that is higher than the extension of the second joint, and is within the adjusting device. The water storage will begin to be directed away from the rainwater retention system and into the public rainwater channel by the first opening 242 of the second joint extension. At this point, the stored water within the conditioning device continues to flow from the conditioning device to the permeable belt via the third joint 260. When the water storage in the adjustment device continues to increase until the second joint extension is submerged, the water storage within the adjustment device is diverted from the third joint 260 to the permeate zone and from the first opening 242 of the second joint extension to the common In addition to the rainwater channel, it will also begin to enter the third conduit from the second opening 244 of the second joint extension and exit to the public rainwater channel.
