Description

The method of subaqueous construction of bridge pier and device
Technical field
The present invention relates to the method and the servicing unit of a kind of method of bridge erection engineering, particularly subaqueous construction of bridge pier.
Background technology
Along with the high speed development of Chinese national economy, highway and railway construction also develop rapidly, and therefore, bridge erection just becomes the key project in the communications and transportation construction, especially in the construction of medium and small river course bridge, have more become the emphasis of emphasis in building.There is long bridge construction history in China, a collection of name bridges such as " The Zhaozhou Bridge " is sparkling in the Chinese nation's magnificent culture in 5000, at present, China can skillfully build length, stride the footpath greatly, the deep water foundation bridge, but, the inventor thinks, in the existing Bridge Pier Construction process of China, when especially in the river course of deep water torrent, constructing, also there is certain problem, because, mostly the construction of bridge pier is to carry out more than the water surface, and some river level is bigger with seasonal variety, and perhaps other reasons causes SEA LEVEL VARIATION (as: downstream dam retaining), thereby cause the bridge pier in the Hot work in progress to be submerged, will stop the construction of bridge pier like this, have only and wait for after water level is decorporated and just can carry out Bridge Pier Construction, cause water level not decorporate if run into some special circumstances, the construction of bridge can only be abandoned or rebuild, and causes huge investment loss.Like this, people have just invented the job practices in bridge pier cofferdam, wherein the steel bushing case is to be applied under the bridge water a kind of water-bound that encloses in the foundation construction, it provides an anhydrous working space for the underwater foundation construction, specifically be with foundation pile top or foundation pile steel casing, working platform is supporting, the outstanding casing that is enclosed within water, by interior plate, base plate and suspension system are formed, its job practices is the work plane that crosses the construction of bridge pier pier stud earlier with steel bushing, seal at casing bottom pouring concrete, after treating that concrete reaches certain intensity, draw water, carrying out the reinforcing bar of whole binder and pier stud pricks, template is installed, last fluid concrete, finish binder and pier stud in the water construction, this job practices requires end steel bushing case big, can all surround two foundation posts of twin shaft pier, and require that enough rigidity and intensity are arranged, thereby the weight of casing is big, disposable input is many, the difficulty of construction height, and the concrete of base plate can not be removed, and has increased difficulty for follow-up construction, therefore, someone has invented patent at Bridge Pier Construction, for example: a kind of new cofferdam construction process for building pier in deep water river (application number is 200510048420), this invention is described to be: framed bent (2) outside build at design bridge pier place in the river course earlier, framed bent (2) is placed outer template (1) near the steel pipe face outside, build interior framed bent (5), place internal layer template (4) near the steel pipe face, between outer template (1) and internal layer template (4), fill soil (3) then at interior framed bent (5), cofferdam (6) interior ponding is extracted out, can in cofferdam (6), be carried out Bridge Pier Construction.But, because above used cofferdam is double-deck, accompany gusset in interior, cofferdam structure is huge, and it is difficult to make, waste timber, the cost height, on-site hoisting, assembly unit, dismantlement work amount are big, and therefore, people are seeking a kind of easy splicing, the readily removable job practices of removing, enclosing the bridge pier cofferdam that water area is little, in light weight, difficulty of construction is little, economical and practical.
Summary of the invention
The objective of the invention is the problem that can continue up to construct, improve the method and the device of the bridge pier subaqueous construction of in bridge foundation construction, using for the bridge pier that solves after not had by water logging.
Realize that method of the present invention is such:
At first on the Bridge Pier Construction place water surface, build floating platform, machined steel casing on the coast, machined steel cover box plate on platform, follow assembly unit first segment steel bushing case on end steel bushing box plate, utilizing crane on the platform will put in order joint steel bushing case after assembly unit is finished mentions, put into water, next joint steel bushing case of assembly unit on the steel bushing case then, make its sinking toward steel bushing case intra-bladder instillation concrete or water again, repeat to support in its assembly unit steel bushing case crossbeam and the steel bushing case, the sinking process arrives from pier shaft end face certain position until hanging steel bushing case crossbeam, after carry out the plan-position adjustment of steel bushing case, and will hang on the pier shaft under the steel bushing case crossbeam position by water under the dirver and to level up with steel plate, the back ballast of pouring water in the steel bushing case chamber, allow the steel bushing case be shelved on the pier shaft top, after having good positioning, the steel bushing case carries out filling out in the pier shaft chamber underwater concreting of core concrete and steel bushing case bottom concrete on pier shaft, after treating that concrete strength reaches designing requirement, drain the water in the steel bushing case, form an airtight no hydrospace, can carry out pier construction at the steel bushing case, after the pier construction water outlet, cutting disassembling part steel bushing case can be finished the subaqueous construction bridge pier under water.
The device of realizing the method for bridge pier subaqueous construction of the present invention constitutes by supporting, hang steel bushing case crossbeam in steel bushing case, steel bushing box plate and the steel bushing case, the steel bushing case is more bigger than the pier shaft size of bridge pier, the steel bushing box plate entangles the pier shaft of underwater foundation during construction, support the pier shaft that an end withstands bridge pier in the steel bushing case, the other end supports the steel bushing chamber interior wall, hangs the top that the steel bushing crossbeam is arranged on the steel bushing case.
Above-described steel bushing case is characterized in that the steel bushing case is the double-walled closed structure, can be in water from floating, and adopt the merogenesis assembly unit, pour water in the steel bushing case chamber and concrete ballast mode is sunk.
Compared with prior art, bridge pier job practices of the present invention has following advantage:
1, the problem that the bridge pier after solution is not had by water logging can continue up to construct is improved the bridge pier subaqueous construction method of using in bridge foundation construction.
2, the cofferdam is thin, and is in light weight without template, easily splicing, readily removable removing, it is little to enclose water area, on-site hoisting, assembly unit, convenient disassembly, and difficulty of construction is little, can reduce the amount of banketing effectively, has significantly reduced construction volume, duration is short, has saved cost, and the dismounting cleaning is easy, thereby has vast market prospect.
