Problems solved by technology

[0007] The object of the present invention is to provide a kind of sponge city green roof that is beneficial to the roof to complete the reduction and purification of rainwater, so as to solve some shortcomings in the design of the existing sponge city green roof proposed in the above-mentioned background technology, such as the above-mentioned invention , only by greening the roof, so as to achieve the effect of rainwater emission reduction, without collecting rainwater, the problem of rainwater emission reduction is very small, and when the rainwater is heavy, all the rainwater falls into the roof, which will inevitably lead to rainwater collection. The problem of tension will further lead to the excess rainwater being drained by the sewer pipes, resulting in waste of rainwater, which is contrary to the design concept of the sponge city; Part of the problem that leads to low utilization of rainwater harvesting

Abstract

The invention provides a sponge city green roof facilitating accomplishment of emission reduction and purification of rainwater for the roof surface. The sponge city green roof facilitating the accomplishment of the emission reduction and the purification of the rainwater for the roof surface comprises layered rainwater collecting grooves, a roof greening layer and a roof water storage tank; the roof greening layer is arranged on a roof body; the layered rainwater collecting grooves are fixedly formed in the upper side of the roof greening layer in a supporting mode through supporting rods; confluence grooves are fixedly formed in the end heads of the lower sides of the layered rainwater collecting grooves; a rainwater collection ditch is formed in one side of two sides of the roof greening layer, and the upper side of the rainwater collection ditch is covered with a greening layer rainwater collecting filter net; the roof water storage tank is arranged on the adjacent side of the roofgreening layer; and eave confluence grooves are connected to the upper side of the roof water storage tank in a supporting mode through water pipes. According to the sponge city green roof facilitating the accomplishment of the emission reduction and the purification of the rainwater for the roof surface, a rainwater collecting eave is designed in an arc-shaped structure, arc-shaped grooves are equidistantly formed in the top surface of the rainwater collecting eave in an arrangement mode, and the collection of rainwater by the arc-shaped grooves rapidly enabling the rainwater to be collectedand flow into the eave confluence grooves is facilitated.

Description

technical field [0001] The invention relates to the technical field of urban roof structure construction, in particular to a sponge city green roof which facilitates the reduction and purification of rainwater on the roof. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. use. Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinat...
