For small bridge, central drainage is often easier to accomplish, its catchment area is less, by deck profile grade or arrange longitudinal drainage pipe, is easy to bridge deck rainwater collecting and is disposed to end of the bridge.And for long-span bridge, because bridge is long, bridge floor is wide, bridge floor catchment area is comparatively large, the rainwater catchment collected to end of the bridge, often need to arrange very thick collection gutter.Collection gutter is excessively thick, and often take the position of bridge floor, increase bridge load simultaneously, at this moment bridge construction often needs to widen or strengthen.And bridge longer time, header is corresponding also longer, and at this moment water velocity is comparatively slow, and rainwater can not be discharged in time, often also can cause bridge floor ponding or unrestrained water, increase the weight of the load of drainage simultaneously.And under normal circumstances, the pollutant contained in early-stage rainwater is more, along with rainfall increases, the degree of contamination of bridge floor ponding also can be more and more less.
How economically by the middle or small bridge floor ponding that rains and other bridge floor wastewater reuse approach, the bridge floor ponding rained greatly can be discharged in time is again the matter of utmost importance of long-span bridge collection Water drainage system design simultaneously.In order to make long-span bridge bridge floor rainwater discharge smoothly, avoiding arranging very thick collection gutter simultaneously, being necessary to invent a kind of novel bridge collection drainage system.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide a kind of by the middle or small bridge floor ponding that rains and other bridge floor wastewater reuse approach, the long-span bridge collection drainage system simultaneously the bridge floor ponding rained greatly can discharged in time again.
The implementation of the utility model object is, a kind of long-span bridge collection drainage system, by the some bridge floor tapping pipes be arranged on bridge floor, longitudinally elongated header and some vertical drainage pipes under bridge floor, and the beam-ends collection gutter of bridge border pier or Abutment and ground collecting-tank composition; Bridge floor tapping pipe is connected by threeway with longitudinal header, and longitudinal header is connected with the beam-ends collection gutter of bridge border pier or Abutment, and beam-ends collection gutter leads to ground collecting-tank; Longitudinal header is connected by elbow communicating pipe with vertical drainage pipe, and described elbow communicating pipe is higher than longitudinal header and vertical drainage pipe; Be provided with expansion coupling in the middle of longitudinal header, vertical drainage pipe, beam-ends collection gutter pipe, and be fixed in bridge construction with pipe clamp or clip.
The utility model utilizes the principle of linker, ponding is discharged by longitudinal collecting conduit and vertical drainage pipeline two kinds of modes, sewage when rainwater is less or on bridge floor, can be collected to the collecting-tank of bridge termination through longitudinal header, discharge or reclaim after purified treatment.When amount of rainfall is very large, longitudinal header drainability is limited, at this moment water is full of in longitudinal header, because elbow communicating pipe is higher than longitudinal header and vertical drainage pipe, lower than bridge floor tapping pipe water inlet, can produce head difference between such bridge floor tapping pipe and vertical drainage pipe water inlet, rainwater flows into vertical drainage pipe and discharges.Simultaneously because elbow linker exceeds longitudinal header, flow into the water in vertical drainage pipe, the partial particulate of the inside and pollutant etc. can precipitate, and can play preliminary effect of filtering.
Adopt the utility model, heavy rain initial stage and moderate rain, light rain or when there are other bridge floor sewage, at this moment discharge is less and seriously polluted, current are discharged after being collected to end of the bridge purified treatment by longitudinal header; In heavy rain situation, at this moment discharge is polluted comparatively greatly comparatively light, and rainwater is discharged fast mainly through vertical drainage pipe, can avoid on bridge, arranged slightly overweight collection gutter, cause structure width and structural load to increase, avoid ponding and Man Shui appear in bridge simultaneously, alleviate drainage burden.In addition for the bridge newly built up, the hazardous substances often on bridge floor is more, or the pollutant that bridge floor is revealed occasionally, can first artificial flushing bridge floor in these situations, and such discharge is less, and hazardous substances can collect the collecting-tank purification of end of the bridge.This sample drainage system also well can adapt to long-span bridge and often require central drainage, the requirement that the later stage can be in line early stage.
The utility model can discharge various bridge floor ponding in time, alleviates bridge load, can reduce bridge floor pollutant etc. simultaneously and directly enter in a large number in river, alleviate blowdown treatment system burden.
