Contacted respectively with one piece of main body side wall of the U-shape structure, the top for often arranging the fender post is accepted described in one respectively
Guan Liang, and the top of the every Guan Liang is concordant with the top end face of the main body side wall of the U types structure；
Adjacent main body side wall and Guan Liang are collectively forming a ring beam bearing structure, and each ring beam bearing structure is held respectively
Connect a ring beam；
The Guan Liang is connected with the ring beam by more joint bars, and the lower end of the every joint bar is anchored into the Guan Liang
And its upper end is stretched into the ring beam；
The top end face of the ring beam is concordant with planning ground.
Preferably, the width of the Guan Liang is equal with the diameter of the fender post.
Preferably, the diameter sum of the thickness of the single main body side wall and fender post is equal to the width of the ring beam.
Preferably, main body side wall, ring beam and the Guan Liang form integrative-structure by joint bar and casting craft.
In general, by the contemplated above technical scheme of the utility model compared with prior art, can obtain down
Row beneficial effect：
1) the utility model sets ring beam in subway gateway open section, and is rigidly connected with Guan Liang, using fender post with
The building enclosure that Guan Liang is collectively forming participates in anti-floating, meets anti-floating requirement, while significantly enhances the main body side wall to U-shape structure
The constraint of upper end, increase the horizontal bending rigidity of main body side wall, reach building enclosure and U-shape structure shared Water And Earth Pressures,
The problem of to improve the main body side wall stress of U-shape structure and arrangement of reinforcement.
2) compared with main body side wall sets groove, directly increases scantling or arrangement of reinforcement, the ring beam and hat of new utility model
The pattern of the common stress of beam, design theory is clear, and challenge is simplified, and has and designs simple, convenient, amount of reinforcement of constructing
It is small, reduce investment outlay, ensure the advantages that structure safety and waterproof effect, the deep-foundation pit engineering such as subway field have preferably application
Prospect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view that the utility model U-shape structure is arranged between two row's fender posts.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.In addition, institute in each embodiment of the utility model disclosed below
As long as the technical characteristic being related to does not form conflict each other, can is mutually combined.
Reference picture 1, Fig. 2, a kind of subway gateway open-mouth section lateral rigidity enhancing structure, including bottom plate 10, two block main bodies
Side wall 1, Guan Liang 2, fender post 3, ring beam 4 and joint bar 5, they are respectively positioned under planning ground 6, plan and be provided with out on ground 6
Ground side wall 7, wherein,
The two block main bodies side wall 1 is arranged on the bottom plate 10 and they are parallel to each other, the bottom plate 10 and two pieces
