Water-saving drainage system for roof

Abstract

The invention discloses a water-saving drainage system for a roof. The water-saving drainage system comprises a main drainage pipeline, an intercepting plug, pumping equipment, a pumping pipeline and a branch drainage pipeline, the top of the main drainage pipeline is connected with a roof drainage outlet, the main drainage pipeline is used for draining roof rainwater to the ground, the intercepting plug is located in the main drainage pipeline and used for intercepting the rainwater drained by the main drainage pipeline, the pumping equipment and the pumping pipeline are used for pumping the rainwater intercepted by the intercepting plug to the roof, two ends of the branch drainage pipeline are butted with the main drainage pipeline, and the branch drainage pipeline is used for draining excessive accumulated water in a bypass after the intercepted rainwater in the main drainage pipeline exceeds a certain water storage height. The purpose of realizing water-saving drainage of the roof is realized.

Description

technical field [0001] The invention belongs to the technical field of roof water-saving drainage structural components, and in particular relates to a water-saving drainage system. Background technique [0002] With the improvement of people's living standards, urban greening construction, increasing urban green coverage area, and improving urban living environment will be more and more highly valued by government departments and urban residents. Due to the construction of a large number of high-rise buildings in the city, the remaining space is limited. Roof greening is also an important way to overcome such problems and increase the urban green coverage area. In many developed countries, greening on the roof, beautifying the environment, reducing pollution, and building sky gardens have become the theme of urban greening in the new era. [0003] As we all know, my country's water resources are quite scarce. With the acceleration of urbanization, many large and medium-siz...

AI Technical Summary

Problems solved by technology

For greening on the roof, using the existing roof conditions, there will be certain limitations: when there is sufficient rainwater, especially when there is heavy rain, the roof is not easy to drain excess water, resulting in roof penetration; when the rainwater is relatively small, it is difficult to collect Sufficient water is likely to cause drought and affect the growth of roof green crops

Using urban tap water systems for pumping irrigation will waste a lot of clean water and energy, and increase the burden of urban water use
