Description
Technical field
The invention belongs to bridge auxiliary equipment field more particularly to bridge pier anticollision device, collision-prevention devices.
Background technique
As transportation develops, the number of navigation ship and bridge is all greatly increased, the probability of ship from colliding bridge
In the trend of cumulative year after year, the design of bridge anti-collision device is necessary.
Conventional anti-collision facility design considers itself steel construction of the anti-collision body of special steel construction mainly to resist ship impact force, steel
Structural collision protection body structure size is big, and processing and scene decentralization project amount are larger.
Summary of the invention
It is an object of the invention to: it proposes a kind of bridge pier anticollision device, collision-prevention device and its construction method, has both had good anti-
Effect is hit, and greatly reduces itself steel construction investment, reduces installation cost, mitigates lifting weight, and improve construction effect, separately
The external bearing platform construction phase, anticollision device, collision-prevention device can be used as water-retaining cofferdam come using.
The object of the invention is realized by following technical proposals:
A kind of bridge pier anticollision device, collision-prevention device construction method, successively the following steps are included:
A. construct pier cap steel cofferdam, steel cofferdam includes enclosing outer Monday closed wall body, inner support wall body it is several
Several shield strings of several guiding devices and the setting of wall body outer wall of steel pipe support and the setting of wall body inner wall；Wall body be include outer wall
The double-layer structure of plate and inside panel is connected between inside and outside siding by several supporting beams and is supported, and the interlayer between inside and outside siding is empty
Between be separated into several compartments by several partition panels along wall body is circumferential, and each compartment lower part is poured concrete, and top fills sand；
B. steel cofferdam sinks；
C. bottom concrete and cushion cap are poured；
E. Bridge Pier Construction finishes, the wall body of steel cofferdam and thereon anticollision device, collision-prevention device of the shield string as bridge pier.
In the present invention program, traditional bridge pier anticollision mentality of designing is abandoned, anti-collision facility has been applied with cushion cap is used for
The steel jacket box of work combines, by the steel cofferdam of script makeshift device, innovative design and as the anticollision of permanent installation fill
Set, the device can the cofferdam as makeshift device and the anticollision device, collision-prevention device as permanent installation, both have both effect, at one stroke
Two.Device uses main pier anticollision double-walled steel jacket box structure, creative in crash-proof steel bushing box design process to propose that " double-wall steel encloses
In weir fill sand+casing outside be arranged shield string " structural measure, guarantee cover box structure energy dissipating while increase steel construction it is integrally rigid
Degree greatly reduces itself steel construction investment, reduces installation cost, simultaneously because dead load is greatly reduced, alleviate lifting
Weight, processing and scene decentralization project amount are greatly reduced, and achieve good economic effect.
Alternatively, in step b, guiding device one end is resisted against on several steel pile castings inside steel cofferdam, passes through guiding
The guiding of device, steel cofferdam is sunk.In the program, guiding device is accurate for steel cofferdam, steadily sinks in place.
Alternatively, in step c, after being poured bottom concrete, steel pile casting exposure bottom concrete part is cut off, cuts off and leads
To device, successively placement layer by layer cushion cap.
Alternatively, the linker being additionally provided on the wall body of steel cofferdam inside and outside connection wall body.
Alternatively, guiding device is equipped at least two layers along short transverse, and steel pipe support is equipped at least two layers along short transverse,
And it is connected and fixed between the support of upper and lower level steel pipe also by vertical steel tube stay.In the program, overall structure is more stable and reliable.
A kind of bridge pier anticollision device, collision-prevention device, including the wall body enclosed around bridge pier one, wall body outer wall is provided with several shield strings, wall
Body is the double-layer structure for including exterior panel and inside panel, is connected and is supported by several supporting beams between inside and outside siding, inside and outside siding
Between interlayer space be separated into several compartments by several partition panels along wall body is circumferential, and each compartment lower part is poured coagulation
Soil, top fill sand.
In the present invention program, each compartment lower part casting concrete is convenient for steel cofferdam sinking, while guarantor is played in counter blade foot position
Shield effect, steel construction is destroyed when avoiding, and the antiseepage after destruction.Wall body top fills sand and had both increased steel construction entirety
Rigidity, at the same when hitting again can effective energy dissipating, wall body outer wall setting shield string be further ensured that set box structure energy dissipating, lead to
It crosses which and steel construction dosage is greatly reduced.The design of the structure of compartment and supporting beam, it is reliable not only to further ensure structure, but also
Play the role of energy dissipating and Global Macros.
Alternatively, shield string is along the arranged circumferentially spaced lopping of wall body, and several circles are arranged in wall body short transverse.It should
In scheme, shield string in the horizontal direction with comprehensive protection can be provided in short transverse.
As further selection, is filled in wall body and protect the whole that string covers bridge pier in wall body short transverse outside sand and wall body
High-low water level constant interval.In the program, fills sand and shield string covers range of stage, regardless of water level changes, Dou Nengyou
Effect protection bridge pier.
Alternatively, the supporting beam between inside and outside siding is using zigzag head and the tail connection arrangement.In the program, effectively take into account
Structure is reliable and energy dissipating acts on.
Alternatively, shield string be rubber material, horizontal section be in hollow trapezoid shape, including towards two outside extend bottom edge,
Inclined waist and the top margin parallel with bottom edge.In the program, the shield string of special designing being capable of most effectively energy dissipating.
The foregoing main solution of the present invention and further alternatives thereof can be freely combined to form multiple schemes, be this
Invention can be used and claimed scheme；And it is of the invention, between (each non conflicting selection) selection and between other selections
It can also be freely combined.Those skilled in the art, which can be illustrated after understanding the present invention program according to the prior art and common knowledge, to be had
