A sunken green space rainwater treatment system and its construction method

Abstract

The invention discloses a sunk type green land rainwater treatment system. The sunk type green land rainwater treatment system comprises a sunk type green land, overflow wells, a pretreatment box and a water storage tank, the left side of the right side of the sunk type green land are both provided with buffer trenches, a water storage cavity is formed under the sunk type green land, the outer side of the water storage cavity is provided with a drain pipe opening, the left side and the right side of the sunk type green land are both provided with overflow pipe openings, the left side and the right side of each buffer trench are provided both with overflow wells, and the drain pipe opening is connected to a rain inlet of a filtering hydrocyclone through a connecting pipe. The construction method comprises the steps of 1, early-stage management; 2, establishment of the sunk type green land, 3, establishment of the overflow wells; 4, installation of the pretreatment box and the water storage box; 5, installation of the filtering hydrocyclone; 6, cleanup, check and repair. The sunk type green land rainwater treatment system is simple in structure and high in practicability, the whole rainwater treatment system is convenient in use, east to construct, convenient in later maintenance, check and repair, much in rain storage amount, and capable of dealing with the condition that a city has a large amount of rainfall.

Description

technical field [0001] The invention relates to a sunken green land rainwater treatment system and a construction method thereof. Background technique [0002] With the acceleration of China's urbanization process and the expansion of cities, problems such as urban waterlogging, rain and flood control, and water shortages have also emerged. In the past, cities relied too much on gray infrastructure to discharge rainwater, which led to the following two phenomena: For cities with a large annual rainfall, the urban drainage pipes were not fast enough when heavy rains occurred due to the small diameter of the pipes when they were designed. Insufficient capacity leads to rainwaterlogging; and for cities lacking rainwater resources, because urban roads and squares are generally paved with hard bricks, a large amount of rainwater resources are poured into drainage pipes, and the impact on water resources in the production and living process Excessive development and pollution hav...

In the past, cities relied too much on gray infrastructure to discharge rainwater, which led to the following two phenomena: For cities with high annual rainfall, because the pipe diameter was too small in design, the drainage speed of urban drainage pipes was not enough when heavy rains occurred. Insufficient capacity leads to rainwaterlogging; and for cities lacking rainwater resources, because urban roads and squares are generally paved with hard bricks, a large amount of rainwater resources are poured into drainage pipes, and the impact on water resources in the production and living process Overexploitation and pollution have led to a water crisis
