Abstract
The utility model relates to a system for reducing the flows of rain water and flood peak for a detention pond. The system comprises a rain falling pipe, a detention pond and a drainage pipe, wherein a front pond partition wall and a rear pond partition wall are arranged in the detention pond, and the detention pond is divided into a front pond, a middle pond and a rear pond by the front pond partition wall and the rear pond partition wall; the rain falling pipe is connected to the bottom of the front pond; the bottom of the rear pond partition wall is provided with a round hole; and the drainage pipe is arranged at the bottom of the rear pond. According to the system for reducing the flows of rain water and flood peak for the detention pond, yielded rain water flows into a municipal rain water pipe network basically with a stable small flow due to the detention effect of the detention pond on the rain water, so that the flood peak is greatly reduced, the load of the municipal rain water pipe network is reduced, and the problem of urban waterlogging is relieved.
Description
[technical field]
The utility model relates to a kind of rainwater catchment system system, is specifically related to a kind of delaying basin and cuts down rainwater peak flood flow system.
[background technology]
Rainwater is a kind of resource of preciousness; In municipal water circulation and regional water circulation, play an important role; Rainwater can slowly be penetrated into underground and keep phreatic renewal and circulation in non-sclerosis place, and unnecessary rainwater then produces runoff and imports renewal and the circulation that surface water body is kept in the sea, river.
But nowadays the city hardening proportion is increasing, and every rainy season, a lot of regional rain inundations were indiscriminate.Many cities surpass the Urban Rainwater Pipe Networks load and cause the city waterlogging because strong rainfall of short time is discharged intensity and strengthened, and the peak flood flow of rainwater can strengthen thereupon.Waterlogging can have a strong impact on urban traffic and resident living, directly and indirect economic loss very serious.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of delaying basin to cut down rainwater peak flood flow system, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem; The purpose of the utility model is to provide a kind of delaying basin to cut down rainwater peak flood flow system, and the rainwater during rainfall gets into delaying basin, and delaying basin is through the delay effect; Make the rainwater water outlet enter into municipal Storm Sewer Network with a stable low discharge basically; Greatly reduce peak flood flow, thereby reduce municipal Storm Sewer Network load, alleviate city waterlogging problem.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of delaying basin is cut down rainwater peak flood flow system, and it comprises rainwater down pipe, delaying basin and discharge pipe; Wherein, be provided with a forebay partition wall and an after-bay partition wall in the said delaying basin, this forebay partition wall and after-bay partition wall are separated into forebay, middle pond and after-bay with delaying basin; Said rainwater down pipe is connected to the bottom, forebay; Said after-bay partition wall bottom is provided with a circular hole; Said discharge pipe is arranged at the bottom of after-bay.
The delaying basin of the utility model is cut down rainwater peak flood flow system and further is set to: be provided with a flower bed in the top of said delaying basin.
The delaying basin of the utility model is cut down rainwater peak flood flow system and also can be set to: said discharge pipe is connected in the municipal manhole.
Compared with prior art, the utlity model has following beneficial effect:
1. storage, cushioning effect through delaying basin when rain water on roof discharges slowly are discharged to municipal pipeline, thereby have cut down the rainwater peak flood flow, have reduced city waterlogging phenomenon.
2. can reduce the city planting ductwork caliber, thereby reduce municipal rainwater pipe overall cost.
3. therefore native system can accomplish gravity drainage because utilized the high elevation of flower bed, does not influence original drainage pipeline networks.
[description of drawings]
Fig. 1 is that the delaying basin of the utility model is cut down the plan view of rainwater peak flood flow system.
Fig. 2 is that the delaying basin of the utility model is cut down the lateral view of rainwater peak flood flow system.
Fig. 3 is to use the curve comparison diagram of native system front and back rainwater flow.
[specific embodiment]
See also shown in Figure of description 1 to the accompanying drawing 3, the utility model is that a kind of delaying basin is cut down rainwater peak flood flow system, and it is made up of several parts such as rainwater down pipe 1, delaying basin 2, discharge pipe 3 and flower beds 4.
Wherein, be provided with a forebay partition wall 21 and an after-bay partition wall 22 in the said delaying basin 2, this forebay partition wall and after-bay partition wall are separated into forebay 23, middle pond 24 and after-bay 25 with delaying basin.Said forebay partition wall 21 is wide 200mm, high 500mm with after-bay partition wall 22.Said after-bay partition wall 22 bottoms are provided with the circular hole 26 that a diameter is 25-75mm, and rainwater can flow to after-bay 25 from middle pond 24 lentamente through this circular hole 26.
Further, be provided with said flower bed 4 in the top of said delaying basin 2, this flower bed 4 overhead has certain altitude, in vegetation 41 and soil 42 are arranged, be used for beautifying the environment.
Said rainwater down pipe 1 one ends connect house roofing 9, and the other end is connected to 23 bottoms, forebay, and its diameter is 100-150mm.
Said discharge pipe 3 is arranged at the bottom of after-bay 25, and this discharge pipe 3 is connected in the municipal manhole 5, thereby the rainwater after just cushioning enters city planting ductwork.
The design principle that the delaying basin of the utility model is cut down rainwater peak flood flow system is following: during rainfall; Rainwater flow to the forebay 23 of delaying basin 2 through rainwater down pipe 1; Rainwater is crossed the middle pond 24 of forebay partition wall 21 entering between forebay 23 and the middle pond 24 afterwards; Circular hole 26 through 25 of middle pond 24 and after-bays gets into after-bay 25 lentamente then, and after-bay 25 is gone in after-bay partition wall 22 overflows in the middle of when rainfall is big, can crossing between pond 24 and the after-bay 25.Rainwater in the after-bay 25 can get into municipal manhole 5 through discharge pipe 3.Through the delay effect of this delaying basin 2, rainwater can balancedly flow into municipal rainwater pipe lentamente, reaches the purpose of cutting down peak flood flow.
The above specific embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
