Abstract

The utility model provides a device for pouring rainwater on a high-rise building roof underground, and relates to the underground water field, in particular to the device which converts rainwater into underground water. The ability of people to exploit and take the underground water increases gradually, so that the water level of the underground water lowers year by year, and the capacity of soil in resisting a drought decreases day by day. In order to promote that the rainwater is poured underground effectively, the device for pouring the rainwater on the high-rise building roof underground is designed. According to the technical scheme, a water container is arranged on the roof of a high-rise building and used for containing collected rainwater; the bottom of the water container is connected to several pipelines, wherein the upper end of each pipeline is provided with an opening which is called a water inlet, the heights of the water inlets increase gradually, each pipeline is divided into two segments, and the connecting position of the two segments of each pipeline is close to the ground and located above the ground to facilitate maintenance; the lower end of each pipeline is located under the ground and provided with an opening which is called a water seepage port. The device for pouring the rainwater on the high-rise building roof underground has the advantages that the rainwater on the roof reaches the ground through the pipelines, and the pressure of the device is higher than the barometric pressure by several times to dozens of times so that the rainwater can be immersed under the ground by a large depth.

Description

A kind of highrise building rain water on roof perfusion underground water device

Technical field

The present invention relates to the underground water field, particularly rainwater is converted into phreatic device.

Background technology

Because the development of technology, people take phreatic ability to strengthen gradually, and phreatic water level reduces year by year, 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.

Phreaticly recharge but few people and pay attention to, the phreatic certainly relatively difficulty of recharging also, main cause is: time of penetration is short, and osmotic pressure is little.In China, the precipitation rareness, precipitation time is short and concentrated, and most of water becomes surface flow and flows to sewer or river, has only a spot of moisture can be penetrated into the shallow-layer of soil; And under the osmotic pressure of rainwater, the slit between the soil molecule is little, and the speed of infiltration is very slow, usually can see, and a heavy rain after the common arid, behind the heavy rain, pick is opened soil at a glance, and it is moistening also having only 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 highrise building rain water on roof and pours into phreatic device.

The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of highrise building rain water on roof 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 net 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, and its low-lying position is beneficial to silt sediment, and water receptacle has overfall, after water receptacle held full water, unnecessary rainwater entered 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 two sections junction is closer apart from ground, and is positioned on the 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 a sealed opening lower end of U-shaped pipe, is called the catch-basin pipeline, opens sealed opening, can clear up the silt and the foreign material that are deposited in the U-shaped pipe.

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

The diameter of pipeline is 5-10cm, the preferred 5cm in the China north, 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, big 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 to safeguard that the local damage of pipeline under ground portion or corrosion do not influence its perfusion effect basically; 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 clear up the silt and the foreign material that are deposited in the U-shaped pipe, reduce pipeline under ground portion shoal materials, influence perfusion effect; Inclination 45 degree in infiltration hole effectively avoid silt to enter pipeline, prolong 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 just is not to intake simultaneously not in same level height, and pipeline is pipe of cement or metal tube, pipeline is divided into two sections, two sections junction 6 is closer apart from ground 3, and is positioned on the ground, so that safeguard; The junction 6 of two segment pipes can be U-shaped pipe 8 roads that expand, the lower end of " U " type pipeline have one can sealed opening, namely the catch-basin pipeline 7, open opening and are 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 infiltration hole 4, and the diameter in infiltration hole 4 is 2mm, is spaced apart 2cm, to the outer direction of pipe, infiltration hole downward-sloping 45 is spent in manage.

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