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 it is day by day low that soil is resisted arid ability.

The but few people that recharge of underground water pay attention to, and recharging of certain underground water is also more difficult, and main cause is: time of penetration is short, and osmotic pressure is little.In China, precipitation rareness, 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 soil molecule is little, 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.Utility model patent, the patent No. 200720087511.7, publication number CN201089953Y is immediate prior art.

Summary of the invention

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

The technical scheme that the present invention realizes goal of the invention employing is: a kind of high building roofing rainwater perfusion underground water device, formed by water receptacle and pipeline, it is characterized in that: have a water receptacle at the roofing of high-rise building, 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, there is heavy mud device, heavy mud device is a ditch, the bottom height in ditch rises and falls, its low-lying position is beneficial to silt sediment, water receptacle has overfall, when water receptacle holds after full water, unnecessary rainwater enters sewer from overfall, water receptacle bottom connects several pipelines, and 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 lower end of duct opening, is called seepage mouth.

The junction of two segment pipes is improved to a U-shaped pipe expanding, and there is the opening of a sealing lower end of U-shaped pipe, is called 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 following part in 10 meters, ground water seepage hole, and the diameter of water seepage hole is 2mm, is spaced apart 2cm, and in managing, to the direction of pipe, water seepage hole downward-sloping 45 is spent.

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, so large high pressure, 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, easy to maintenance, and the under ground portion of pipeline does not need maintenance substantially, and the local damage of pipeline underground part or corrosion, 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 are conducive to cleaning and are deposited in silt and the foreign material 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.

Detailed description of the invention

There is a water receptacle 1 at the roofing of high-rise building, 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, there is heavy mud device, 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 when water receptacle holds after full water, unnecessary rainwater enters sewer.

Water receptacle 1 bottom connects several pipelines, the opening of pipeline, it is water inlet 2, water inlet 2, not at 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, i.e. catch-basin pipeline 7 is opened opening for clearing up the silt and the foreign material that are deposited on U-shaped pipe 8.

The lower end of pipeline is positioned at underground, according to the present situation of 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 following part in 10 meters, ground water seepage hole 4, and the diameter of water seepage hole 4 is 2mm, is spaced apart 2cm, from in managing to the direction of pipe, water seepage hole downward-sloping 45 is spent.

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 are full, or rainwater is larger, and reserve-water-level rises, by high perfusion water inlet any pipeline.
