Abstract
The invention relates to a drainage system for an urban low-lying area. According to the terrain of the urban low-lying area, a rainwater backward flowing inlet is found, 1-3 rows of open type drainage pipelines are transversely arranged in the rainwater backward flowing inlet, lawns are laid between the open type drainage pipelines, and the open type drainage pipelines are directly connected into a main urban drainage system. A side pavement in the urban low-lying area is paved with water seepage bricks under the situation that a height difference exists in the urban low-lying area. The drainage system has the advantages that by simply transforming the urban low-lying area, plugging is achieved, and rainwater can be prevented from entering the low-lying area through the open type drainage pipelines.
Description
Technical field
The present invention relates to a kind of drainage system, particularly relate to low lying areas, city drainage system.
Background technology
China's size of population is many, urban house is intensive, initial stage urban planning is unreasonable, therefore causes the low lying areas in the numerous city of China to have construction house, and most low lying areas are in old town, its municipal drainage system is weak, its house road of heavy rain is i.e. flooded whenever, resident trip inconvenience, and house on road surface and automobile are easily by water logging, easily there is epidemic situation in drowned poultry animal, causes strong influence to local resident；Currently in order to the problem solving the draining of low lying areas, city, it is generally only and regularly drainage pipeline is dredged, but it is big all in old town, its drainage pipeline caliber is little, also can only meet resident's proper drainage demand after dredging, as needed heavy rain, it is low because of physical features, rainwater pours into low lying areas in a large number, and low lying areas drainage system can not bear.
Drainage problem for low lying areas, city, mostly also it is focused only in the most fast automatic draining, as Publication No. CN202416528U discloses low lying areas anti-waterlogging drainage arrangement, it prevents waterlogging simply by water lev el control gate and suction pump, this device can only prevent the rainwater of drainage pipeline from will not pour in down a chimney, and because low lying areas physical features is low, flows into after city rainwater highly is inevitable, as this part rainwater can not be solved, the purpose that low lying areas, city are flooded can not be prevented；Publication No. CN202390912U discloses a kind of low lying areas, city discharge structure, its function singleness, fundamentally can not be fully solved the problem that low lying areas, city are flooded, presently disclosed technical literature is the most all from a certain problem unilaterally overcoming draining, because the heavy rain oncoming force is anxious, rainwater is poured in down a chimney again in low lying areas, can not solve, by the technology of single aspect, the problem that low lying areas, city are flooded.
Summary of the invention
It is an object of the invention to provide a kind of low lying areas, city drainage system, solve low lying areas, existing city and easily flooded, and overcome that existing solution technology is single, the unconspicuous problem of regulation effect.
The present invention is realized in, it is characterized in that: according to low lying areas, city landform, rainwater is found to pour in down a chimney entrance, pour in down a chimney entrance at its rainwater and be transversely provided with 1-3 row's open type drainage pipeline, it is covered with lawn between described open type drainage pipeline, and open type drainage pipeline is directly accessed city main drainage system, footpath in low lying areas, city uses seepage brick to lay, in the case of there is ground, difference in height hole in low lying areas, by the hole of each high elevation by drainage pipeline access low-lying hole ground, it is provided with sump on the ground in the hole of described low-lying, sump accesses city main drainage system by drainage pipeline, described sump is provided with gate one with the junction of drainage pipeline, the drain pipe of described sump is provided with gate two with the junction of city main drainage system.
The height of water level of the drain pipe that the ground, hole of described high elevation enters the ground, hole of low-lying should be higher than that the drainage pipeline height of water level of its low lying areas, city itself.
The well head height of described sump is above the ground level 4-8cm.
The bottom of described sump is provided with water pump.
The solution have the advantages that: by the simple transformation to low lying areas, city, first " blocking up " is achieved, the open type drainage pipeline arranged by 1-3, allow rainwater will not enter into low lying areas, be then " collection ", by rainwater-collecting unnecessary for low lying areas at one, but only collect rainwater, sewage in original drainage pipeline is not collected, make full use of sump, after heavy rain, further through water pump, the water of low lying areas is quickly discharged by drainage pipeline and seepage brick, for preventing the water outside low lying areas from pouring in down a chimney further, it is provided with gate at the seam accessing city main drainage pipeline, thus form low lying areas, city drainage system.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of the present invention.
Fig. 2 is the top view of the present invention.
In the drawings, 1, low lying areas, city 2, rainwater pour in down a chimney entrance 3, open type drainage pipeline 4, sump 5, drainage pipeline.
Detailed description of the invention
nullSuch as Fig. 1、Shown in Fig. 2，The present invention is realized in，According to low lying areas, city 1 landform，Rainwater is found to pour in down a chimney entrance 2，Pour in down a chimney entrance at its rainwater and be transversely provided with 1-3 row's open type drainage pipeline 3，So rainwater outside low lying areas is flowed into open type drainage pipeline，It is directly discharged in the main drainage system of city by open type drainage pipeline，So can effectively reduce rainwater and enter into low lying areas in a large number，And according to rainwater flow，1-3 row is set，Thus prevent because rainwater flow is big，Can not be flowed in main drainage system by open type drainage pipeline to greatest extent，Setting by multiple rows of open type drainage pipeline，Ensure that rainwater will not enter into low lying areas layer by layer，It is covered with lawn between described open type drainage pipeline，And open type drainage pipeline is directly accessed city main drainage system，Rainwater flow velocity can be reduced by lawn，More rainwater is allowed to enter open type drainage pipeline，And rubbish can be stopped by lawn，Prevent from rubbish from entering into drainage pipeline to result in blockage；nullFootpath in low lying areas, city uses seepage brick to lay，This is to not result in surface gathered water after the rain，In the case of there is ground, difference in height hole in low lying areas，By the hole of each high elevation by drainage pipeline access low-lying hole ground，It is provided with sump on the ground in the hole of described low-lying，Sump 4 accesses city main drainage system by drainage pipeline，And the height of water level of the drain pipe that the ground, hole of high elevation enters the ground, hole of low-lying should be higher than that the drainage pipeline height of water level of its low lying areas, city itself，So only when original drainage pipeline full load，Rainwater just can enter into the drainage pipeline being connected with sump，Avoid because light rain will the problem filled of sump，When heavy rain comes interim，Sump will not play and act on，Described sump is provided with gate one with the junction of drainage pipeline 5，The drain pipe of described sump is provided with gate two with the junction of city main drainage system，Gate one、The purpose of two is when city main drainage system full load，Prevent city main drainage system rainwater from pouring in down a chimney，After heavy rain，Rainwater in sump is extracted out by the water pump utilizing the bottom of sump，Wait that next time uses，The 4-8cm and the well head height of sump is above the ground level，When being also to ensure that light rain，Surface gathered water will not enter in sump，Only have more than set water level range，Its rainwater just can be entered in sump by drainage pipeline and sump well head.
