Description
Technical field
The invention belongs to Municipal Drainage Engineering technical field, is related to the structures that urban discharging pipeline drops, more particularly to
A kind of big flow, height fall poor draining drop well and its multilayer energy dissipating construction method.
Background technology
Municipal drainage pipeline mainly includes sewage conduct, storm sewer and rainwater, sewage combined pipeline.Three kinds of pipelines relate to
And the arrangement of inspection shaft.According to《Code for design of outdoor sewerage engineering (GB50014-2006<Version in 2014>)》(abbreviation outdoor drainage is set
Specification is counted, similarly hereinafter), " position of inspection shaft, it should be located at pipeline intersection, turning, caliber or gradient change, drop and sentence
And locate at a certain distance on straight line pipeline section.”
Drop well is a kind of important composition form of inspection shaft, solves different discrepancy in elevation ground rainwaters, dirt using drop well
The Dissipation of Energy of the gravity drainage of water etc..At drop, when drop depth h >=5m when, current will produce greatly impact
Power, formed for pipe network and inspection shaft and significantly washed away, and then the safe and stable operation of high risks drainage pipeline networks.Therefore,《Room
Outer Drainage Design specification》Regulation：" when pipeline drop head is 1.0~2.0m, preferably set drop well；When drop head is more than 2.0m,
Drop well should be set.Drop well should not be set at pipeline turning "；" when the water inlet pipe caliber of drop well is not more than 200mm, once drop
Head height cannot be greater than 6m；When caliber is 300mm~600mm, the head height that once drops is not preferably greater than 4m.Drop mode can
Using vertical tube or rectangle vertical slot.When caliber is more than 600mm, its once drop head height and drop mode should be according to water force
It is determined that.”
Moreover, as the continuous quickening of Urbanization in China, city are faced with huge and deep change.Give
It is water, draining (including rainwater, sewage, interflow etc.), reclaimed water, electric power, cable, combustion gas, fuel oil, heating power, fire-fighting, illumination, communication, wide
The substantial amounts of underground utilities such as electricity are distributed on town road, cause the extreme of Subsurface crowded.Urban drainage pipe network leads to
Normal caliber is larger, and generally requires the conduit slope needed for guarantee gravity stream, while in order to avoid other pipelines, drainage pipeline networks
Buried depth often can be larger, and the depth of inspection shaft (containing drop well) also accordingly increases.
At present,《Drainage inspection well》Atlas (02 (03) S515) has included 3 kinds of drop wells, respectively riser type drop well,
Vertical slot formula drop well and staged drop well.Wherein riser type drop well is applied to fall the cast iron pipe that caliber is not more than 200mm,
Fall the sewage pipe that difference is 1~6m；It is 200~600mm that vertical slot formula drop well, which is applied to fall caliber, and it is dirty for 1~4m rain to fall difference
Water pipe；It is 700~1650mm that staged drop well, which is applied to fall caliber, falls the rainfall and sewage pipes that difference is 1~2m.Above-mentioned three class
It is only 6m that drop well, which most slumps poor, and it is only the cast iron sewage pipe for being not more than 200mm that 6m, which falls corresponding during difference, it is difficult to meets draining
The needs of pipe network latest development.For the situation of larger water inlet pipe caliber, above-mentioned figure mainly by the way of falling step by step, takes up an area
Space is larger, according to 700~1650mm of caliber, falls poor 1~2m, inspection shaft inside dimension length needs 2.5~4m, and width needs
Want 1.8~2.75m.
Therefore, a kind of draining drop well with the effect that saves land for falling poor scope suitable for big flow, height of research is needed badly.
The content of the invention
In view of this, an object of the present invention is to provide a kind of big flow, height falls poor draining drop well, to solve to pass
Big flow, the Dissipation of Energy for the difference that slumps being not directed in system draining drop well；Meanwhile the second object of the present invention is to provide one
