Problems solved by technology

In particular, due to the special hydrogeological conditions of some sunken squares, the bottom plate may be located in a phreatic aquifer, so the water level elevation of the phreatic water in the site area is higher than that of the bottom plate of the sunken square. Therefore, the safety and normal use of the sunken square functionality, etc., may be affected by this
The floor is the lowest elevation of the sunken square, and the submerged layer is generally 2.14-7.32 meters underground. If the bottom of the sunken square is buried at a depth of 6.3 meters and is in the submerged layer, water will seep into the sunken square, causing safety and environmental problems.

Embodiment Construction

[0026] The technical solution of the present invention will be described in further detail below, and it should be noted that the specific implementation is only a detailed description of the present invention and should not be regarded as a limitation of the present invention.

[0027] The sinking square water circulation system based on the sponge city of the present invention mainly includes an isolation unit, a pipe network collection unit, a groundwater level control unit and a rainwater reuse unit, such as Figure 1-3 shown;

[0028] In some preferred modes, the isolation unit includes a water-stop curtain 8; the sunken square is separated from the surrounding groundwater aquifer by using the water-stop curtain 8; as figure 1 As shown, the water-stop curtain 8 is used to isolate the groundwater for the entire sunken square, that is, the ground connection wall can be used on the basis of connected buildings as the water-stop curtain 8, as shown in FIG. Figure 1-2 As sho...

Abstract

The invention discloses a sunken square water circulation system based on a sponge city. The system mainly comprises an isolation unit, a pipe network collection unit, an underground water level control unit and a rainwater reuse unit, the isolation unit comprises a waterstop curtain, the pipe network collection unit comprises a pipeline and an impounding reservoir, the underground water level control unit comprises a water level monitoring device and an underground water well, the rainwater reuse unit comprises a purifying device, the water circulation system adopts the waterstop curtain forcarrying out underground water separation, through the water level monitoring device, the underground water well and the impounding reservoir, the underground water level is controlled, it is ensuredthat the sunken square underground water level is kept below a bottom plate, meanwhile, existing rainwater, water draining, underground water control, green landscape, paving and the like are sufficiently used, the water circulation system and a water quality control and rainwater reuse system are built, and effective combination of sponge city ecological functions and square original functions can be achieved.

Description

technical field [0001] The invention belongs to the field of rainwater regulation and storage and resource utilization, and in particular relates to a water circulation system for sunken squares based on sponge cities. Background technique [0002] The sunken square means that the whole or part of the square sinks into its surrounding environment, forming an enclosed open space. The industrial revolution in the eighteenth century aggravated the contradictions of urban construction while enabling the rapid development of capitalist cities. By the mid-1970s, Western countries advocated the renewal and development of urban architecture. The sunken square breaks the traditional square design concept, and uses vertical traffic to integrate various planar activity venues to connect them as a whole. With the development of science and technology, underground space has been fully and effectively utilized. [0003] In terms of rainwater drainage design, the design requirements for...
