Height-adjustable's overflow well

Technical Field

The utility model relates to an urban rainwater is collected and is discharged technical field, concretely relates to height-adjustable's overflow well.

Background

Along with the acceleration of the urbanization process, the waterproof ratio of the urban underlying surface is increased, so that the drought and waterlogging condition of the city is easy to occur. To solve such problems, the country advocates building a sponge city and a set of low-impact development rainwater systems to solve the above problems.

The rainwater garden is an important unit in sponge city construction, can collect rainwater from a roof or the ground, purify the rainwater through the filtering action of soil and plants, temporarily accumulate the rainwater, and then slowly go deep into the soil, so that the surface runoff is reduced, the rainwater flood is controlled, and the rainwater is utilized. Therefore, the problem of drought and waterlogging caused by the increase of the proportion of the urban impervious underlying surface is solved. In addition, the rainwater garden also has ornamental and ecological properties.

In the rainwater garden of construction at present, after the overflow well is installed and fixed, the height of an overflow port is parallel and level with a water storage layer of a green land, and when the height of rainwater exceeds the water storage capacity of the rainwater garden, rainwater can enter the overflow well through the overflow port and then be discharged into a city rainwater pipe network. For water safety, the rainwater garden impoundment infiltration time also needs to be completed within a certain time. However, the rainwater is stored in the rainwater garden for a long time due to the fact that the water storage layer is saturated at the lower part of the rainwater garden or the permeable layer is blocked, and finally the water quality is poor, peculiar smell is generated and the like.

In addition, in the construction of sponge cities, the heights of water storage layers of different rainwater gardens are different, while overflow wells are usually prefabricated standardized products, and the rainwater gardens are complicated in construction due to the fact that the overflow wells of the same type need to be installed at different heights.
