Abstract

A roof rainwater collecting and utilizing system comprises a water storage unit and a water drainage unit. The water storage unit is fixedly laid in a roof area defined by a roof parapet wall, and thewater drainage unit is fixedly arranged on a parapet wall body. The water storage unit comprises a waterproof film, a water storage layer, a sand stone layer and a plant greening layer which are sequentially laid from bottom to top, wherein the waterproof film is laid on the roof top face and the parapet wall body. The water drainage unit comprises an overflow pipe, an emptying pipe and a water drainage vertical pipe. The overflow pipe penetrates through the middle portion of the parapet wall body, and the emptying pipe penetrates through the root of the parapet wall body. One ends of the overflow pipe and the emptying pipe communicate with the interior of the roof area, and the other ends communicate with the water drainage vertical pipe fixedly arranged on a building outer wall. A reusepump is fixedly arranged in the roof, the water inlet end of the reuse pump communicates with the interior of the water storage layer, and the water outlet end of the reuse pump communicates with a rainwater utilization device. According to the system, plants and soil can be adopted for purifying a water body, the functions of rainwater overflow and accumulated water freezing preventing are achieved, the structure is simple, cost is low, and construction is easy.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a roof rainwater collection and utilization system. Background technique [0002] Water resources are scarce in my country, especially in remote mountainous areas where drinking water is scarce in places where the population lives scattered. When traditional water resources development methods can no longer increase water sources, recycling rainwater has become an economical and practical way to develop water resources. Rainwater is a high-quality freshwater resource in nature. Recycling rainwater not only has a significant water-saving effect, but also alleviates the water resource crisis. However, rainwater contains impurities, sediment, heavy metals, organic matter and bacteria, and the content of ammonia nitrogen is also high. The direct use of rainwater still has the problem of poor water quality. However, the existing rainwater recycling devices mostly deposit...
