Abstract
The utility model discloses a kind of steel box-girder drainage-free tube built-in drainage systems, the water inlet including bridge floor and being uniformly arranged on bridge floor, it further include rhone, the rhone is placed in inside steel box-girder, bridge both sides are longitudinally laid in along bridge, positioned at the lower section of bridge floor, the water inlet is arranged in above rhone.The steel box-girder drainage-free tube built-in drainage system of the utility model has many advantages, such as to be not easy to plug, does not destroy that the airflow design of steel box-girder outer profile, wind resistance is more excellent, simple in structure and service life is long.
Description
Technical field
The utility model belongs to drainage system more particularly to a kind of release installation row in steel box bridge structure auxiliary equipment
The built-in drainage system of water pipe.
Background technology
Bridge structure is made of four essential parts, i.e. superstructure, substructure, bearing and auxiliary equipment, and is drained
System is the important component in bridge auxiliary equipment.In order to prevent as bridge structure accept a surrender water erosion and caused by bridge floor row
Vehicle is difficult, dangerous, and convenient and perfect drainage system should be arranged to improve the durability of bridge.
In steel box bridge common drainage system generally by bridge floor, water inlet, tapping pipe, longitudinal drainage pipe, downpipe and
End of the bridge collection drainage facility forms, and bridge floor precipitation generally flows into water inlet by deck transverse slope and longitudinal slope, then is collected to by tapping pipe vertical
To drainpipe, end of the bridge Ji Shuisheshichu most is drained into through downpipe afterwards, wherein tapping pipe and longitudinal drainage pipe is generally suspended on steel
On the outside of box beam, and steel case girder is commonly applied to the Longspan Bridges such as suspension bridge, cable-stayed bridge, and Longspan Bridge wants wind resisting stability
Ask higher, thus generally the outer profile of steel box-girder is designed as it is streamlined to meet its wind resisting stability, if drainpipe is hung
On the outside of girder, the airflow design of steel box-girder section is destroyed, and also adds wind resistance area, significantly reduces steel in this way
The wind resistance of box bridge；And tapping pipe and drainpipe pipe cross and elbow are more, be easy because water wash away the fallen leaves to get off,
The blockings such as rubbish and mud, so, it, need to be to commonly using drainage system to avoid commonly using the above-mentioned deficiency of drainage system in steel box bridge
Improved.
Utility model content
Technical problem to be solved in the utility model is to overcome the shortcomings of to mention in background above technology and defect, is carried
For a kind of steel box-girder drainage-free tube built-in drainage system for being not easy to plug, not destroying steel box-girder outer profile airflow design.
In order to solve the above technical problems, the utility model proposes technical solution be：
A kind of steel box-girder drainage-free tube built-in drainage system, including bridge floor and the water inlet that is uniformly arranged on bridge floor,
Further include rhone, the rhone is placed in inside steel box-girder, and bridge both sides are longitudinally laid in along bridge, is located under bridge floor
Side, the water inlet are arranged in above rhone.
As a further improvement of the above technical scheme：
Further include the downpipe and end of the bridge collection drainage facility for being installed on end of the bridge, end of the bridge end and the downpipe of the rhone connect
It connects, water is drained into end of the bridge collection drainage facility.
The rhone is made of base and impervious barrier, and the outside of base is wrapped in outside the impervious barrier.
The base is the bridge steel plate of 4mm~10mm thickness, and the impervious barrier is the austenitic stainless steel of 3mm~6mm thickness.
Compared with prior art, the utility model has the advantage of：
The utility model uses rhone draining, compared to the pipe drainage system comprising tapping pipe Yu longitudinal drainage pipe
System, elbow greatly reduce with connector quantity, avoid the problem of drainpipe is easy to block, and rhone is placed in steel box-girder
Portion will not reduce the wind resisting stability of steel box-girder because destroying steel box-girder outer profile airflow design, exactly because also it is set to
Inside steel box-girder, reduce the contact with external environment so that the service life of rhone extends, and reduces maintenance frequency, saves
Manpower, time and materials.

Specific implementation mode
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to the utility model
Work more comprehensively, meticulously describes, but the scope of protection of the utility model is not limited to embodiment in detail below.
Embodiment
As shown in Figure 1 and Figure 4, the steel box-girder drainage-free tube built-in drainage system of the present embodiment, including bridge floor 1 and uniformly
The water inlet 3 being arranged on bridge floor 1 further includes rhone 2, and rhone 2 is placed in inside steel box-girder, will not be because destroying outside steel box-girder
Profile airflow design and the wind resisting stability for reducing steel box-girder, exactly because be also set to inside steel box-girder, reduce with outside
The contact of boundary's environment so that the service life of rhone extends, and reduces maintenance frequency, saves manpower, time and materials, and keep away
The problem of pipe drainage system is easy to block is exempted from, rhone 2 is longitudinally laid in bridge both sides along bridge, is located under bridge floor 1
