Abstract

The invention belongs to the technical field of rainwater utilization and provides a method for collecting rainwater for roof greening. The roof greening rainwater collection method comprises the following steps: (1) building a sash with a height of 8-12cm on the roof; (2) setting a plurality of rows of grid groups in parallel in the sash grid, and the grid groups include the first row of adjacently arranged grid and the second row of grids; the first row of grids is filled with mixture, and the raw materials of the mixture include expanded vermiculite, peat, compound fertilizer and plant seeds; the top of the second row of grids is sealed with the first open-hole membrane, and the A second perforated film is pasted around; multiple channels are opened between the first row of grids and the second row of grids; (3) collecting rainwater. The method is simple to operate, not only can effectively collect roof rainwater, avoiding damage to the roof caused by accumulated rainwater, but also can directly use the collected rainwater for roof greening, saving time and labor and beautifying the environment.

Description

technical field [0001] The invention belongs to the technical field of rainwater utilization, and in particular relates to a method for collecting rainwater for roof greening. Background technique [0002] In recent years, as the scarcity of water resources has become more and more serious, people have shifted their attention to the recycling of water resources, especially the use of rainwater resources has become a current hot spot. [0003] At present, a variety of rainwater collection systems have been developed, but these systems have disadvantages such as time-consuming and labor-intensive, complicated and bulky equipment, high cost, and little effect. [0004] Therefore, inventing a kind of roof greening rainwater collection method that can solve the above problems has become a problem to be solved urgently at present. Contents of the invention [0005] Aiming at the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a m...
