Description
Technical field
The invention belongs to Municipal Drainage Engineering technical field, relate to the structures of urban discharging pipeline drop, particularly to
A kind of big flow, height fall poor draining drop well and multilamellar energy dissipating construction method thereof.
Background technology
Municipal drainage pipeline mainly includes sewage conduct, storm sewer and rainwater, sewage interflow pipeline.Three kinds of pipelines all relate to
And the layout of inspection shaft.According to " Code for design of outdoor sewerage engineering (GB50014-2006<2014 year version>) " (it is called for short outdoor drainage to set
Meter specification, lower same), " position of inspection shaft 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, utilizes drop well to solve different discrepancy in elevation ground rainwater, dirt
The Dissipation of Energy of the gravity drainage of water etc..At drop, as drop degree of depth h >=5m, current will produce impact greatly
Power, is formed for pipe network and inspection shaft and significantly washes away, and then the safe and stable operation of high risks drainage pipeline networks.To this end, " 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, once drop head height is not preferably greater than 4m.Drop mode can
Use 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
Determine.”
Moreover, along with the continuous quickening of Urbanization in China, city is faced with huge and deep change.Give
Water, draining (including rainwater, sewage, interflow etc.), middle water, electric power, cable, combustion gas, fuel oil, heating power, fire-fighting, illuminate, communicate, extensively
The substantial amounts of underground utilities such as electricity are distributed on town road, and the extreme causing Subsurface is crowded.Urban drainage pipe network leads to
Often caliber is relatively big, and it is generally required to ensure the conduit slope needed for gravity stream, simultaneously in order to dodge other pipelines, drainage pipeline networks
Buried depth often can be relatively big, and the degree of depth of inspection shaft (containing drop well) increases the most accordingly.
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 applicable to fall the cast iron pipe that caliber is not more than 200mm,
Fall the soil pipe that difference is 1~6m;It is 200~600mm that vertical slot formula drop well is applicable to fall caliber, falls the rain that difference is 1~4m dirty
Water pipe;It is 700~1650mm that staged drop well is applicable to fall caliber, falls the rainfall and sewage pipes that difference is 1~2m.Above-mentioned three classes
The drop well difference that slumps most is only 6m, and corresponding when 6m falls poor is only the cast iron sewage pipe being not more than 200mm, it is difficult to meet draining
The needs of pipe network latest development.For the situation of bigger water inlet pipe caliber, above-mentioned figure mainly uses the mode fallen step by step, takes up an area
Space is relatively big, according to caliber 700~1650mm, falls and differs from 1~2m, and inspection shaft inside dimension length needs 2.5~4m, and width needs
Want 1.8~2.75m.
Therefore, need that research a kind of is applicable to big flow, height falls the draining drop well with the effect that saves land of poor scope badly.
Summary of the invention
In view of this, an object of the present invention is to provide a kind of big flow, height to fall poor draining drop well, to solve to pass
System draining drop well in be not directed to big flow, slump poor Dissipation of Energy;Meanwhile, the two of the purpose of the present invention are to provide one
Plant the multilamellar energy dissipating construction method with the effect that saves land, the design of drop well in the build-up region nervous for land used, pipe network is intensive
Reference is provided.
