Description

Technical Field

[0001] The utility model relates to the technical field of rainwater storage and regulation, and in particular to a temporary rainstorm peak shifting system based on a sponge city. Background Art

[0002] In recent years, under the background of global climate change, extreme weather represented by rainstorms has become increasingly frequent. Since the current construction standards of rainwater drainage pipes and pump station facilities are generally low, their scale cannot meet the requirements of the new drainage standards.

[0003] The existing rainwater drainage system is generally upgraded by adding rainwater pipes and expanding the capacity of pumping stations to ensure regional drainage safety. However, due to the busy urban traffic, numerous infrastructure and pipelines under urban roads, and land shortage, it is extremely difficult to renovate rainwater drainage pipes and build new rainwater storage tanks.

[0004] Rainwater storage tanks are mainly used to regulate and store rainwater. They are part of the sponge city drainage system, can alleviate urban flood disasters, improve rainwater utilization, and are an important part of sponge city construction. Regulating and storing tanks have begun to be built all over the country to retain and store rainwater. However, because the regulating and storing tanks need to occupy a large amount of underground space, they have the disadvantages of high site selection requirements, great impact on the surrounding areas, long construction period, and high project investment. As a result, the construction of urban regulating and storing tanks is slow, affecting the construction of sponge cities. Traditional rainwater regulating and storing devices occupy a large area and are difficult to develop. They are not suitable for temporary collection and regulation when heavy rains come.

[0005] Therefore, a temporary storage system for storing rainwater and flexibly discharging it at off-peak times is still to be developed. Utility Model Content
