Abstract

The invention discloses a rainwater collecting system for a roof garden and a construction method. The system includes a roof, a water collection unit, a processing unit, a water storage unit and a water consumption unit. The roof is provided with a cobbled road paved with pebbles and a first vegetation layer. The water collection unit includes a rainwater collection hopper arranged blow the cobbled road and a water delivery pipe. The processing unit includes a landscape pool, a sedimentation tank and a purifier, wherein the landscape pool, the sedimentation tank and the purifier are successively connected. The water storage unit includes a first reservoir and a second reservoir, wherein the first reservoir is positioned on the roof and the second reservoir is positioned below a house. The system integrates roofing construction, rainwater collection, water treatment and water use terminals. Making overall plans and taking all factors into consideration, the system can efficiently reduce rainwater pollution, protect water environment and achieve collection, purification, storage and reuse of rainwater. The system also improves the water-use efficiency, reduces the pressure of water use, makes it more convenient to conserve and irrigate a roof garden, and reduces the energy for water delivery, so that the system is more economical and environmentally friendly.

Description

technical field [0001] The invention relates to a rainwater collection and storage system for roof gardens and a construction method thereof. Background technique [0002] In the existing technology, rainwater harvesting should be called "rainwater harvesting and utilization system" in a complete way, which refers to the collection and utilization of rainfall runoff collected on the roof of buildings, roads, squares and other hardened surfaces. Water—storage and other channels accumulate rainwater, and provide rainwater replenishment for greening, landscape water bodies, washing and groundwater sources, so as to achieve the purpose of comprehensive utilization of rainwater resources and water conservation. The tap water supply in many cities and regions has been difficult to keep up with the pace of urbanization. Emerging water industries such as watering and greening the city, flushing roads and other public welfare water, and car washing have further increased the burden ...
