Description
Technical Field
The invention belongs to the technical field of rainwater regulation facilities, and particularly relates to a rainwater regulation system combined with a cover plate and a regulation method thereof.

Along with the rapid development of urban construction, rail transit becomes a main tool for solving the problem of ground traffic in cities. The vehicle base land comprehensive development can not only utilize the land to a greater extent and obtain the comprehensive development effect of ' one land ' and two purposes ', but also support subway construction by establishing the economic value of back feeding mechanism development upper cover development, thereby relieving the fund pressure. At present, a plurality of vehicle bases are developed on the upper cover nationwide. However, since vehicle base and upper cover developments are often different phases of construction, and vehicle base cover panels are often underground garage floors of the upper cover development property, to save investment, upper cover panels are one-piece hardened roofs and will have a longer time before upper cover property development. The upper cover plate is a temporary roof of the vehicle base, and the waterproof hardened roof has large rainwater runoff, so that the rainwater runoff of the vehicle base developed by the upper cover is often far more than that before construction, and the urban and rural flood control and drainage capacity is greatly reduced.
In order to improve the urban and rural flood control and drainage capacity, the urban and rural flood control system accords with the national concept of sponge urban building, and controls the rainwater runoff from the source so that the constructed rainwater runoff does not exceed the rainwater runoff before construction. At present, an ecological landscape pond, a circulating water pond, a sinking green land and the like are arranged on a vehicle base, and when the cover plate is in a temporary state, rainwater regulation and storage are often carried out again when the upper cover is subjected to secondary development, and at the moment, rainwater regulation and storage measures set by the temporary cover plate can be abandoned. Many projects simply provide a submerged green field on the reserved ground of the vehicle base for temporary storage of rain water during heavy rain. Because the vehicle base occupies a large area, the cover plate area is large, the occupied area required by a landscape pond, a circulating water pond or a sinking green land is large, the engineering cost is high, and the water pond also has certain maintenance risks. Along with the secondary development of the cover plate, greening and permeable paving facilities are adopted when the upper cover is developed, and the water quantity required by rainwater regulation facilities such as a landscape pond or a sinking green land can be greatly reduced, so that the construction is often a temporary facility when the upper cover is not developed.
