Abstract
An urban rainwater drainage system comprises a rainwater catch basin arranged under a tarred road and next to curbstones; the port of the rainwater catch basin is connected with the tarred road through a perforated strainer; one side of the upper part of the rainwater catch basin is connected with the upper part of an inspection chamber through a water discharge pipe; the inspection well is one part of a sewer parallel to a road; a water seepage well is straightly inserted underground; a movable inspection well cover is arranged on the inspection well; and an angle between the water discharge pipe and the sidewalk pavement is 15 degrees to 25 degrees. The urban rainwater drainage system can supply partial rainwater for underground water through the water seepage well and store the partial rainwater underground, thereby increasing the amount of underground water and upraising the water level of underground water, and also can solve the problem of siltation of a sewer, thereby ensuring smooth water discharge and sharply reducing rain-flood disasters at the same time.
Description
Technical field
The utility model relates to a kind of urban rainwater exhaust system.Belong to urban rainwater water discharge technology field.
Background technology
Rainwater is a precious water resource, surface water no matter, or underground water all comes from the supply of rainwater, does not have the supply of rainwater all will become water without a source.Because the continuous expansion on waterproof ground, city, cut off rainwater to phreatic supply, zonal water circulation is destroyed, and exploiting groundwater and yield grow with each passing day throughout the year, and groundwater level is descended, thereby cause land subsidence, cause that above ground structure is crooked, collapse that plant is withered, so dryness of air, rainwater is injected underground, recharge groundwater has crucial sincere justice.Because it is underground that rainwater injects, recharge groundwater can make the city exempt from the puzzlement of heat pollution and drought and water shortage, helps to improve The Surroundings in Cities.Fundamentally, rainwater utilization is exactly in order further to solve city water resource and environmental problem.And present situation is: after rainwater drops to ground in the city, be pooled to the inlet for stom water that is arranged on the road and enter sewer and flowed out the city and drained, this precious water resource is slatterned in vain.In the prior art in order to utilize rainwater preferably, common way is, catch-basin is arranged on the tarmac road edge, near kerb, manhole is set below the sidewalk, manhole is provided with sewer, concrete culvert pipe with great by one section 30 centimeters diameter between catch-basin and the sewer connects, and an end of culvert pipe is arranged on the bottom of catch-basin, the other end is connected manhole, rainwater is discharged outside the city by the sewer that culvert pipe flows in the manhole, covering drain cover on the catch-basin well head, drain cover is the ironcasting of 75*45 specification, there are 27 19cm long on the drain cover, 2.5cm wide hole, therefore, on the ground, foreign material on the road surface are as grass end, paper scrap, cigarette end, dust etc. can both enter catch-basin, the alluvial catch-basin, the water draining is received in influence, moreover be that drain cover is usually lost, easier alluvial after drain cover is lost, accident easily meets accident simultaneously.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of novel urban rainwater exhaust system to be provided.
A kind of urban rainwater exhaust system of the present utility model is achieved through the following technical solutions:
A kind of urban rainwater exhaust system, comprise and being arranged on below the tarmac road, catch-basin near kerb, catch-basin can be Any shape, as the cylinder bodily form, cuboid or other shape, the oral area of described catch-basin connects tarmac road by grate, make rainwater to flow into smoothly in the catch-basin, described catch-basin top one side is connected with manhole top by tapping pipe, tapping pipe is a concrete culvert pipe with great, in the described manhole sewer is set, sewer is connecting municipal sewers, and described sewer bottom is connected with negative well by trashrack, described negative well is directly connected in underground, is provided with manhole cover versatilely above the described manhole.
Described tapping pipe becomes 15-25 degree angle with the road surface, sidewalk.Be that tapping pipe connection catch-basin one end is higher than connection manhole one end, so that the water of catch-basin can successfully flow into manhole.
The utility model has following beneficial effect with respect to prior art:
1, urban rainwater exhaust system of the present utility model is made a call to a negative well at the manhole place of sewer, and the part rainwater is arrived underground water by the negative well supply, is stored in underground.
2, urban rainwater exhaust system of the present utility model has solved the alluvial problem of sewer, discharges unobstructed.
3, urban rainwater exhaust system of the present utility model solves rain flood problem.
Description of drawings
Fig. 1 is the sectional structure chart of urban rainwater exhaust system of the present utility model;
Fig. 2 is that urban rainwater exhaust system of the present utility model is implemented illustration.
The specific embodiment
Understand the technical solution of the utility model for one of ordinary skill in the art can be known, the existing work in conjunction with the accompanying drawings further at large illustrates:
A kind of urban rainwater exhaust system, as shown in Figure 1, comprise and being arranged on below the tarmac road 1, catch-basin 10 near kerb 11, the oral area of catch-basin 10 connects tarmac road 1 by grate 2, catch-basin 10 tops one side is connected with manhole 6 tops by tapping pipe 3, along road in the described manhole 6 sewer 7 is set vertically, described sewer 7 is parallel with the road surface, negative well 9 is established in described manhole 6 bottoms, described negative well 9 well heads are established trashrack 8, sewer 7 bottoms are connected with negative well 9 by trashrack 8, and negative well 9 is directly connected in underground, is provided with manhole cover 4 versatilely above the manhole 6.
Tapping pipe 3 becomes 15-25 degree angle with 5 road surfaces, sidewalk.
Embodiment
During construction, according to constructing as shown in Figure 1, build according to structure as shown in Figure 1 according to certain distance at urban road, build catch-basin 10 in tarmac road 1 liang of outside, near kerb 11, build manhole 6 in sidewalk 5 times, tapping pipe 3 is connected catch-basin 10 with angled ground, road surface one end, the other end is connected the top of manhole 6, keep tapping pipe 3 and road surface to form 15-25 degree angle, under the road surface in city, build aforementioned discharge structure according to certain distance, tarmac road 1 bilateral symmetry construction, sewer 7 under the road surface connects into a urban rainwater discharging network with this structure, when rainwater by tarmac road 1 runoff behind catch-basin 10, the end that tapping pipe 3 is connected with catch-basin 10 is arranged on the top of catch-basin 10, and tapping pipe 3 becomes 15-25 degree angle with the road surface, make the water of catch-basin 10 can successfully flow in the manhole 6 and flow into sewer 7, the bottom of sewer 7 connects negative well 9, therefore, the part water of sewer 7 can penetrate into underground by negative well 9, has guaranteed phreatic supply at any time from face.Simultaneously, negative well 9 is provided with trashrack 8 with the junction of sewer 7, thereby mud can not flow into the alluvial that negative well 9 causes negative well 9 yet.Desilting regularly in the manhole 6, it is smooth and easy to guarantee that it flows, and catch-basin 10 also can play the desilting effect, the desilting that flows to 10 li of catch-basins on the road surface just can not flow in manhole 6 and the sewer 7 by tapping pipe 3 yet.Urban rainwater exhaust system of the present utility model can be the part rainwater by negative well 9 supplies to underground water, be stored in undergroundly, guaranteed phreatic preservation, but also solved the alluvial problem of sewer 7, discharge unobstructedly, also solved the big vast problem of rain simultaneously.
