Abstract
The utility model relates to a kind of assembled downcomer structures, it is characterised in that a kind of assembled downcomer structure, inlet opening is arranged in the side wall along downcomer, and loaded filter is set on the outside of inlet opening；The downcomer of bottom is connect with prefabricated tip, and the downcomer at top is connect with prefabricated pipe cap, and strut beam is arranged on prefabricated pipe cap；Connecting groove is arranged in the adjacent vertical joint of downcomer, and passes through hoop plate connection；Hole is passed through in the side wall setting drain groove of downcomer, top setting hoist cable.The utility model can not only save the expense of live drainage construction, and site operation efficiency and quality can be improved, and can also reduce the influence to surrounding enviroment.
Description
Technical field
The utility model relates to downcomer structure, in particular to a kind of site operation it is convenient and can synchronize meet it is multi-faceted
The assembled downcomer structure of drainage requirement, belongs to field of civil engineering, is suitable for temporary drainage engineering.
Background technique
Area of heavy rainfull or groundwater level region carry out Construction of Civil Engineering, and many kinds of measures need to often be taken to reduce underground water
Position, common practice is cast-in-place gully or laying gutter etc. at present, though these measures can meet scene to a certain extent
Drainage requirement, but that the construction period is longer, drainage effect is affected by the external environment is larger.
In consideration of it, urgently being invented at present effectively to promote live drainage construction efficiency and construction quality, reducing project cost
A kind of expense that can not only save drainage of foundation pit, and the assembled downcomer knot of site operation efficiency and quality can be improved
Structure.
Utility model content
The purpose of this utility model is to provide one kind can effectively improve live drainage construction efficiency and quality, saves work
Journey cost, the assembled downcomer structure for dropping low environmental impact.
To realize the above-mentioned technical purpose, the utility model uses following technical scheme:
A kind of assembled downcomer structure, inlet opening is arranged in the side wall along downcomer, and anti-filter is set on the outside of inlet opening
Layer；The downcomer of bottom is connect with prefabricated tip, and the downcomer at top is connect with prefabricated pipe cap, and is arranged on prefabricated pipe cap and is held
Press beam；Connecting groove is arranged in the adjacent vertical joint of downcomer, and passes through hoop plate connection；It is recessed in the side wall setting draining of downcomer
Slot, top setting hoist cable pass through hole.
The downcomer is using steel pipe or Reinforced Concrete Materials is prefabricated forms, and cross section is at round or rectangle or ellipse
Shape.
The caliber of the downcomer passes through reinforcement compared with the prefabricated pipe pinnacle face small 0~00mm of diameter, downcomer and prefabricated tip
Bolted angle connection.
The utility model have the characteristics that it is following and the utility model has the advantages that
(1) the utility model assembling type drainage pipe on-site assembly is convenient, and site operation efficiency can be substantially improved, and reduces construction
Influence to surrounding enviroment.
(2) it is provided with inlet opening and drain groove on the utility model assembled downcomer side wall, different zones can be met
Foundation drainage requirement.
