Description

Green drainage integral structure of planting of building roofing

Technical Field

The utility model relates to the technical field of building drainage, in particular to a green planting and drainage integrated structure of a building roof.

Background

Building roofs generally refer to roofs of buildings, and drainage treatment is generally required on the building roofs to prevent water leakage of the roofs caused by rainwater residence.

At present, the drainage mode of the roof is mainly divided into two types, one type is non-organized drainage, and the other type is organized drainage. And (3) inorganized drainage: the roof rainwater drainage system is also called free water falling, and is a drainage mode that roof rainwater directly falls to the outdoor ground from cornice, and has the advantages of simple structure and low manufacturing cost, but the roof rainwater freely falls to splash the wall surface, the outer wall basement is often eroded by the splashed rainwater, the firmness and durability of the outer wall are affected, the traffic of a sidewalk is possibly affected, and the unorganized drainage mode is mainly applicable to low-rain areas or general low-rise buildings and is not applicable to street-free buildings and high-altitude buildings. Organized drainage: roof rainwater is orderly discharged to the outdoor ground or an underground pipe ditch through a drainage system. The wall surface spraying device has the advantages of no obstruction to pedestrian traffic and difficulty in splashing the wall surface, so that the wall surface spraying device is widely applied to constructional engineering. But is relatively complex in construction and relatively expensive to manufacture compared to the unstructured drainage.

The water is classified by the drainage mode, and is mainly divided into an external drainage mode and an internal drainage mode. And (3) external drainage: the common external drainage mode is three modes of parapet external drainage, parapet external drainage and parapet external drainage. In general, an external drainage scheme should be adopted as much as possible, because the organized drainage structure is complex, and leakage is easily caused. In general civil buildings, the most commonly used drainage modes are parapet outer drainage and gutter outer drainage. Internal drainage: the water drop pipe is positioned on the inner side of the outer wall, the middle span of the multi-span house is of a simplified structure, and an inner drainage mode can be adopted when the conditions of beautiful outer vertical surface of a high-rise building, freezing blockage prevention of the water drop pipe in cold areas and the like are considered.

The Chinese patent (application number 2017215583242) discloses a roof water circulation and drainage system, which belongs to an external drainage scheme of organized drainage, and the system recycles rainwater through a roof rainwater collection unit and a water terminal, and sets a roof greening water pipe network at the water terminal, so as to set a water storage tank required by roof green planting growth, thereby achieving the technical scheme, timely supplementing water resources of a landscape water tank and improving the utilization rate of rainwater; the phenomenon of road surface water accumulation caused by water body overflow is reduced; meanwhile, the water level of the landscape pool is controlled within a safe range, so that the safety performance of the landscape pool is improved.

This technical scheme combines roofing water resource recycle with the green plant of roofing, reach the saving water source, beautify the effect of roofing, but this technical scheme has certain defect, first this technical scheme needs to install a plurality of siphon type rainwater hoppers on the building roofing and be used for the drainage, waterproof treatment point position increase of rainwater hopper and building roofing like this, waterproof treatment pressure is big, and through waterproof treatment, the aesthetic degree of building roofing greatly reduced, the corresponding also big improvement of risk that the building roofing leaked, simultaneously, the mounted position of rainwater hopper must be higher than the view pond, when the rainwater volume is great, the rainwater can pass through the drain pipe, pour into the view pond backward through the outlet, increase the load of suction pump, increase the energy consumption that the rainwater utilized, uneconomical. In addition, the building roof space is occupied by the rainwater hopper and the water storage tank provided with the green plants respectively, so that the green planting area on the upper part of the building roof is reduced, and the building roof is not attractive.
