The bottom of beam body 1 is equipped with multiple bridge piers 2, and the top of bridge pier 2 is equipped with bridge pier pier shaft or capital bent cap 3, bridge pier pier shaft or capital lid
Beam 3 limits stabilizing mechanism 4 by multiple buoyancy and connect with bridge beam body 1, and buoyancy limit stabilizing mechanism 4 includes being mounted in bridge pier pier
The integral type steel panel 5 of 3 top of body or capital bent cap, the bottom of bridge beam body 1 is equipped with beam bottom voussoir 6, integral type steel face
Plate 5 is equipped with collar stop 7, and bridge pier pier shaft or capital bent cap 3 indulge bridge and be equipped with located lateral block 8 to side, located lateral block 8 with
Bridge pier pier shaft or capital bent cap 3 are fixedly connected, and multiple steel buoyancy tanks 9 are equipped with around bridge pier pier shaft or capital bent cap 3, and steel is floating
Case 9 is connect by guide rail mechanism with located lateral block 8, beam bottom voussoir 6 and integral type steel panel 5 and is welded on integral type steel
Collar stop 7 on panel 6 is in nest relation in the plane, and collar stop 7 covers when floating with buoyancy limit stabilizing mechanism in beam
The outside of bottom voussoir 6.
In the present invention, it is thick according to 2 pier shaft of bridge pier to size that 5 gabarit of integral type steel panel indulges bridge（Bent cap is wide）And steel is floating
Case 9 indulges bridge to depending on length, and direction across bridge size is depending on 7 width of 6 width of beam bottom voussoir and collar stop, intermediate cut-out
Size should be not less than 6 contour dimension of beam bottom voussoir.
Collar stop 7 is system component nested with beam bottom voussoir 6, is hollowed out by the fashioned iron customized along integral type steel panel 5
Part edge welding fabrication, structure height should be high not less than voussoir.
The buoyance module of single set buoyancy limit stabilizing mechanism 4 is made of four steel buoyancy tanks 9, to adapt to flow characteristics, steel
9 shape of buoyancy tank processed may be tailored to ship type.The top of steel buoyancy tank 9 is welded with 5 bottom of integral type steel panel, make vertical bridge to steel
Realization and pier shaft between buoyancy tank 9（Bent cap）Nesting；, nesting nested with located lateral block 8 is realized between the steel buoyancy tank 9 of direction across bridge
Relationship realizes that the guide rail mechanism includes the pre-buried steel that 3 side of located lateral block 8 or capital bent cap is arranged in by guide rail mechanism
Groove 10 processed, pre-buried steel groove embed tetrafluoro plate 11, and the side of steel buoyancy tank 9 is equipped with the sliding block 12 of welding, and sliding block 12 is located at
It is contacted in pre-buried steel groove 10 and with tetrafluoro plate 11, wherein pre-buried steel groove 10 is on located lateral block 8 towards bridge pier 2
Short transverse extends.
The construction of located lateral block 8 can be depending on engineering properties.For example newly building bridge needs corollary system, can be directly with pier
Body（Bent cap）One-piece casting is formed at reinforced concrete member or pre-buried fashioned iron.For example strengthening and rebuilding engineering, then can be used bar planting again with
The means molding such as fashioned iron welding.By locating piece and the consolidation relationship of bridge pier and with the nested realization of system buoyancy tank side wall laterally
Positioning.
The steel plate model of system use, O. gracilipes can be according to actual bridge scale, execution conditions, support, voussoirs etc.
Bridge structure size takes the circumstances into consideration to customize.
The system is after completion of assembly and when coming into operation, and when flood situation occurs, flood level overflows 2 top of bridge pier and steel
When buoyancy tank 9 processed contacts, after steel buoyancy tank 9 is by water level buoyancy, the sliding block 12 on the steel buoyancy tank 9 of 3 circumferential surface of roof rail is in transverse direction
It is mobile towards the top of bridge pier 2 in the pre-buried steel groove 10 of 3 side of locating piece 8 and capital bent cap, pass through sliding block 12 and pre-buried steel
The cooperation of groove 10 processed can guarantee the stability that steel buoyancy tank 9 moves up and down, due to 9 top of steel buoyancy tank and integral type steel
The welding of 5 bottom of panel, and collar stop 7 and integral type steel panel 5 are welded, then, in steel buoyancy tank 9 by water level buoyancy
When moving up, the buoyancy of integral type steel panel 5, collar stop 7 and steel buoyancy tank 9 as a whole limits stabilizing mechanism one
It rises towards the movement of the bottom of bridge beam body 1, when water level is sufficiently high, collar stop 7 is directly sleeved on the outside of beam bottom voussoir 6 and and bridge
The bottom of beam body 1 contacts, and the mutual of collar stop 7 and beam bottom voussoir 6 is supported by buoyancy that water level generates steel buoyancy tank 9
Nesting, while utilizing collar stop 7 and the nested and buoyancy of beam bottom voussoir 6 limit stabilizing mechanism and bridge pier pier shaft or capital lid
The mutually nested realization of beam 3, located lateral block 8 is to the limit effect of bridge beam body.
This system realizes that vertical bridge realizes that horizontal system is determined to system positioning, by located lateral block from capital bent cap or pier shaft
Position；Guide rail mechanism guarantee buoyancy limit stabilizing mechanism with water level generate vertical direction upper and lower displacement to realize flood situation occur and
At the end of with beam bottom voussoir 6 dock and disengaging（Flood situation in the past after, water level decreasing, steel buoyancy tank 9 is automatic under self gravity
Decline, beam bottom voussoir 6 are automatically separated with collar stop 7）.When flood situation, which causes bridge beam body to have, drifts about possible, so that it may logical
It crosses with the nested of system and its position constraint generated with bridge pier to avoid the generation of dangerous situation.
This system construction is succinct, bill of material one, simple process, easy to maintain, is not required to by water body buoyancy starting additionally dynamic
Force system；Size and shape can be flexible and changeable according to the actual situation, guaranteeing and bridge upper and lower part constitution realization interface flexibility
In the case of do not influence bridge good appearance；It can largely be used because cheap.
This system is not in the case where interfering bridge original structure to construct, using buoyancy variation in standby, starting two states
Lower switching, it can be ensured that the position that bridge beam body meets with when water level rises suddenly and sharply and generates floating is stablized, disaster caused by avoiding because of unstability
Property consequence.
In addition, this system can be also used in, Bridge position is limited or flood situation is frequent, the super larger area of designed flood frequency possibility
In the newly building bridge and old bridge reinforcewent in domain.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
Improvement is both fallen in the range of claimed invention.The present invention claims protection scope by appended claims and its
Equivalent defines.
