Description

Building terrace rainwater savings use device
1, affiliated technical field
Building terrace rainwater savings use device of the present utility model belongs to water resource and utilizes the field.
2, background technology
Freshwater resources are more and more poorer, the problem that has become the whole world to pay close attention to, and China is one of country of serious water shortage in the world, there is more than 600 urban water shortage in the whole nation.Yet, a large amount of freshwater resources-rainwater, but after the building terrace is accepted, the overwhelming majority is gone into sewer and is slatterned in vain by in line.Existing building rainwater recycle device (number of patent application: 01230313.5), be the terrace rainwater directly to be entered the pond that is provided with downstairs collect, be used for greening, carwash etc.Yet above-mentioned rainwater is recycled method and is still had following shortcoming:
1. the rainwater of Hui Shouing and other daily life sewages mix, and rotten easily the change makes the water quality variation, only can be used for some low-grade purposes such as greening, carwash, and value is not high, and will pay muscle power or other energy;
2. bigger pond to downstairs be set, just can reach the purpose of relatively large recovery.But in city densely populated, an inch of land is an inch of gold, it obviously is unpractical that such pond is set in a large number.Thereby be difficult to popularize, just do not reach the large tracts of land rainwater yet and reclaim, make full use of the purpose of water resource.
3, summary of the invention
The purpose of this utility model is to provide a kind of building terrace rainwater savings use device, it can accept, collect and save rainwater on the building terrace, and it is indoor and downstairs directly to send into each layer by sewer pipe, be used for washing, pouring flowers and plants, flush the toilet etc., after purifying after filtration, also can be used for diet.
The purpose of this utility model, can realize by following technical measures: on building sky facial plane water receiver is set, rain collecting layer is set above water receiver, rain collecting layer is provided with the inlet opening, be connected to sewer pipe on the water receiver, sewer pipe passes through each floor and enters into indoor and wait the water place downstairs.
Above-mentioned water receiver is square or the flat peviform of polygon; dark is 25-40cm; ageing-resistant, dense material with function admirable are made; also available steel concrete when building sky surface layer is constructed together ramming or separately ramming become base; add water impervious layer in its surface again and topping forms, with building sky surface layer one integrated mass.Water receiver can have only one, also can be combined by a plurality of, has pipeline to interconnect between each water receiver.
Above-mentioned rain collecting layer is the imporosity plane layer that feet is arranged, and there is the dash limit that is higher than its plane at the edge, and make with the ageing-resistant material of sun-proof a little more than water receiver at its end, and it is thick in can bear pedestrian's degree of being.Whole layer is to slightly tilting on one side or being the branch water setting of ridge, is provided with at least one inlet opening at the rainwater place of converging, and the inlet opening is provided with grid formula and basket formula strainer.The area of rain collecting layer is equal to or greater than water receiver actinal surface area, and maximum can cover whole building terrace.
Above-mentioned sewer pipe upper end is communicated with water receiver, vertically passes through each floor from top to bottom, and the horizontal launching pipe is set in each layer, is provided with water valve (tap) in the sewer pipe end.Simultaneously, also be provided with at least one overflow pipe, to get rid of terrace ponding.
The utility model is when rainy, and the strainer of the rainwater that rain collecting layer is accepted from the inlet opening of passing through enters water receiver and save, and the rainwater of savings is sent into indoor the reaching of each layer by sewer pipe and used easily for people downstairs.
The beneficial effects of the utility model are:
1. the rainwater of collecting can be saved, substitute part of running water, lower urban water use pressure; Make full use of freshwater resources, energy conservation, and easy to use.
2. water receiver can replace the terrace waterproofing course, and rain collecting layer replaces isolation layer, and also can do activity such as leisure in the above.Thereby wide adaptability, cost is low, profitable relatively, can large scale application.
