Abstract

The invention provides a device using rainwater on a roof of a high-rise building to fill ground water, and relates to the field of ground water, in particular to a device for converting rainwater into ground water. The capability of using the ground water by people is gradually improved, the water level of the ground water is reduced yearly, and the capability of soil resisting drought is increasingly reduced. The device using the rainwater on the roof of the high-rise building to fill the ground water is designed, so as to promote the rainwater to be effectively filled into the ground. The device adopts the technical scheme that the roof of the high-rise building is provided with a rainwater container, and the rainwater container is used for accommodating the collected rainwater; the bottom of the rainwater container is connected with several pipelines, the upper end of each pipeline is opened and is used as a rainwater inlet, the heights of the rainwater inlets are gradually increased, each pipeline is separated into two sections, and the connected part of the two sections is arranged close to the ground and is positioned above the ground, so the maintenance is convenient; and the lower end of each pipeline is positioned under the ground, is opened, and is used as an infiltration opening. The device has the beneficial effect that the rainwater on the roof reaches the ground through the pipelines, and several to dozens of atmospheric pressures are reached, so the rainwater can infiltrate into the ground with a deeper depth.

Description

A kind of high building roofing rainwater perfusion underground water device

Technical field

The present invention relates to Field of Groundwater Study, particularly rainwater is converted into the device of underground water.

Background technology

Due to the development of technology, people take the ability of underground water to strengthen gradually, and the water level reduced year by year of underground water causes the water content of soil shallow-layer more and more lower, and the ability that soil is resisted arid is day by day low.

The few people that recharge but of underground water pay attention to, certainly underground water recharge also more difficultly, main cause is: time of penetration is short, osmotic pressure is little.In China, precipitation is rare, and precipitation time is short and concentrated, and most of water becomes surface flow and flows to sewer or river, only has a small amount of moisture can be penetrated into the shallow-layer of soil; And under the osmotic pressure of rainwater, the gap between the soil molecule is little, and the speed of infiltration is very slow, usually can see, and a heavy rain after common arid, after heavy rain, pick is opened soil at a glance, and it is moistening also only having simple upper soll layer.

Summary of the invention

Effectively perfusion is underground in order to promote rainwater, and the present invention designs a kind of device of high building roofing rainwater perfusion underground water.

the present invention realizes that the technical scheme that goal of the invention adopts is: a kind of high building roofing rainwater perfusion underground water device, formed by water receptacle and pipeline, it is characterized in that: the roofing at high-rise building has a water receptacle, water receptacle holds the rainwater of collecting, the water inlet end of water receptacle has the grid screen of impurity screening, on the path of rainwater process, heavy mud device is arranged, heavy mud device is a ditch, the bottom in ditch just rises and falls, its low-lying position is beneficial to silt sediment, water receptacle has overfall, after water receptacle holds full water, unnecessary rainwater enters sewer from overfall, the water receptacle bottom connects several pipelines, and the pipeline upper end open is called water inlet, and the height of water inlet increases successively, and pipeline is pipe of cement or metal tube, and pipeline is divided into two sections, and the junction of two sections is closer apart from ground, and is positioned on ground, so that safeguard, lower end of duct is positioned at underground, and the lower end of duct opening is called seepage mouth.

The junction of two segment pipes is improved to a U-shaped pipe that expands, and there is the opening of a sealing lower end of U-shaped pipe, is called the catch-basin pipeline, opens the opening of sealing, can clear up the silt and the foreign material that are deposited in U-shaped pipe.

Seepage mouth is preferably placed at underground 50 meters, and pipeline is positioned at the part of ground below 10 meters water seepage hole, and the diameter of water seepage hole is 2mm, is spaced apart 2cm, and to the outer direction of pipe, water seepage hole downward-sloping 45 is spent in manage.

The diameter of pipeline is 5-10cm, the preferred 5cm of north of China, the preferred 10cm of southern china.

The invention has the beneficial effects as follows: the height of highrise building arrives hundreds of rice at tens meters now, the rainwater on roof arrives ground by pipeline, can reach several to dozens of atmospheric pressure, large high pressure like this, can make rainwater immerse the very dark degree of depth of below ground, this part rainwater relies on the pressure of head effectively to pour into by pipeline becomes underground water; Device is simple, and pipeline is divided into two sections, and is easy to maintenance, and the under ground portion of pipeline does not need maintenance basically, and local damage or the corrosion of pipeline underground part do not affect its perfusion effect; Two segment pipe junctions arrange U-shaped pipe, are conducive to silt and foreign material and are deposited on U-shaped pipe, and U-shaped pipe has seal to open, and is conducive to clear up the silt and the foreign material that are deposited in U-shaped pipe, reduce pipeline underground part shoal materials, affect perfusion effect; Water seepage hole inclination 45 degree effectively avoid silt to enter pipeline, extend the application life of pipeline.

The specific embodiment

Roofing at high-rise building has a water receptacle 1, water receptacle 1 is collected the rainwater of roofing, and the water inlet end of water receptacle 1 has the filtration grid of impurity screening, on the path of rainwater process, heavy mud device is arranged, heavy mud device can be a ditch, and the bottom in ditch is not smooth, but height rises and falls, its low-lying position is beneficial to silt sediment, water receptacle 1 has overfall, and after water receptacle held full water, unnecessary rainwater entered sewer.

Water receptacle 1 bottom connects several pipelines, the opening of pipeline, it is water inlet 2, water inlet 2 not at the same level height, is not namely to intake simultaneously, and pipeline is pipe of cement or metal tube, pipeline is divided into two sections, the junction 6 of two sections is closer apart from ground 3, and is positioned on ground, so that safeguard; The junction 6 of two segment pipes can be U-shaped pipe 8 roads that expand, and there is an opening that can seal the lower end of " U " type pipeline, and namely the catch-basin pipeline 7, opens opening and is used for silt and the foreign material that cleaning is deposited on U-shaped pipe 8.

The lower end of pipeline is positioned at underground, present situation according to present urban groundwater, the lower ending opening of pipeline, be that seepage mouth 5 is preferably placed at underground 50 meters, pipeline is positioned at the part of ground below 10 meters water seepage hole 4, and the diameter of water seepage hole 4 is 2mm, is spaced apart 2cm, to the outer direction of pipe, water seepage hole downward-sloping 45 is spent in manage.

The order of perfusion is that short water inlet 2 pipelines pour at first, then take second place, and are conducive to like this improve the hydraulic pressure of perfusion, improve perfusion effect; After the 2 pipelines perfusions of short water inlet were full, perhaps rainwater was larger, and reserve-water-level rises, with high any the pipeline of perfusion water inlet.
