Problems solved by technology

The application of storm runoff control in my country is still limited to some areas of the city, and the scope of application is small, and the application level of planning and design tools supported by advanced technology is low or not applied, resulting in the effect of engineering application is not obvious
At the level of urban planning, there is no specific urban storm runoff management plan aimed at flood control, water quality protection, and landscape comprehensive effects, and comprehensive control of storm runoff is rarely considered in urban master planning

Embodiment Construction

[0027] Specifically the implementation

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] see Figure 1 to Figure 8 A rainwater collection and interception system for a green building community is shown, which is composed of multiple subsystems connected in series in a low-lying green space.

[0030] The sewage interception and infiltration system consists of water inlet pipe 1, water collection well A2, water holding garden A4, water holding garden B5, packing well 9, water collection well B16, water outlet pipe 17, and external permeable packing layer 19 outside the well.

[0031] The water inlet pipe 1 is connected to the lower left part of the water collection well A2 with an impermeable manhole cover, and the outlet pipe 17 is connected to the upper right part of the water collection well B16 with an impermeable manhole cover; the packing well 9 with a well grate 10 on the top is located in the water col...

Abstract

The invention discloses a green rainwater collection and sewage interception system for building districts, which comprises a plurality of subsystems which are serially connected and arranged in a low-altitude greenbelt in a district. Each subsystem comprises a sewage interception infiltration subsystem and route infiltration drainage subsystem. Rainwater flowing in the system is subjected to accumulation, storage, infiltration, detaining and energy dissipation, and amount of thermal rainwater discharge is reduced greatly. When permeating a permeable filling layer, a water-holding garden planting soil layer, a filling layer of the water-holding garden planting soil layer, a filling layer of a filling well and the like outside the system, the rainwater is adsorbed, infiltrated and held, and pollutant carried by the rainwater is removed effectively. Amount and quality of collected water are controlled at the terminal of the system, and the terminal rainwater can be collected for reuse or drained into a municipal rainwater network. In addition, flowing time of the rainwater in drainage is prolonged, urban rainwater flood peaks can be lowered, urban living environment can be beautified, and natural hydrographic cycle balance can be maintained.

Description

technical field [0001] The invention belongs to the technical fields of municipal engineering and environmental protection, and in particular relates to a rainwater collection and interception system for a green building community. Background technique [0002] Rainwater is an important link in the urban water cycle and regional water cycle system, and plays an extremely critical role in regulating and supplementing regional water resources and improving the ecological environment. China is currently in the stage of rapid urbanization. With the improvement of urbanization level and rapid economic development, the problem of urban rainwater is becoming more and more prominent. The main manifestations are: serious pollution of rainwater runoff; increased risk of urban flood disasters; massive loss of rainwater resources; serious damage to the urban ecological environment, etc. Many of the planning and design of urban drainage systems in our country still only stay on how to d...
