Upper-lower layer rainwater sharing circulation system for green fabricated building

Abstract

The invention discloses an upper-lower layer rainwater sharing circulation system for a green fabricated building. The circulation system comprises a green plant layer and a wall, a stone layer is arranged below the green plant layer, a filter screen is arranged below the stone layer, a floor drain is arranged below the filter screen, a water return branch pipe is arranged below the floor drain, the periphery of the water return branch pipe is connected with a top plate, a water filtering room is connected to the left end of the top plate, a water storage tank is arranged inside the water filtering room, a water filtering pipe is connected to the upper portion of the water storage tank, and a purifying device is connected to one end of the water filtering pipe. According to the fabricated building upper-lower layer rainwater sharing circulation system for the green building, a water return main pipe is arranged, and rainwater collecting devices on all layers are enabled to be in communication, so that rainwater can be uniformly collected and distributed, it is guaranteed that plants on all the layers can be well irrigated, and the situation that plants on a certain layer are short of water, while plants on the top layer die due to excessive water is avoided.

Description

technical field [0001] The invention relates to the technical field of green prefabricated buildings, in particular to an upper and lower rainwater sharing circulation system for green prefabricated buildings. Background technique [0002] Green building is an architectural concept advocated by today's society. It integrates natural plants and buildings well. By planting green vegetation on the top of the building and on the protruding parts of each floor, it not only ensures sufficient greening, but also ensures that the building The prefabricated building is a construction method that is convenient for building construction today. By prefabricating various areas of the building in the factory building, the building construction only needs to put the prefabricated building parts in place and build them up. It greatly facilitates the construction of the building. By integrating the concept of green building with the prefabricated building method, it can quickly build a green...

Problems solved by technology

[0007] The purpose of the present invention is to provide a rainwater circulation system for the upper and lower layers of green prefabricated buildings, so as to solve the problem that the rainwater circulation system of the prefabricated buildings of green buildings on the market can only collect single-layer rainwater. , resulting in too much water on the top layer of plants, the root system is soaked and rotted, causing the plants to die, while the lower layer is too little water, causing the plants to die due to lack of water. The rainwater circulation system of the prefabricated building of the traditional green building can only circulate the rainwater to irrigate the plants, and the excess rainwater However, it cannot be well utilized, and domestic sewage cannot be well utilized to increase nutrients for plants. At the same time, rainwater containing sediment is likely to cause pipeline blockage in the rainwater circulation system.
