Abstract
The utility model relates to a steel cofferdam assembled floating platform and belongs to the technical field of bridge construction. The steel cofferdam assembled floating platform comprises a plurality of short bored pile steel casings and at least two long bored pile steel casings, wherein the short bored pile steel casings are arranged at the lower parts of linear wall plates at two sides of a steel cofferdam and are vertical to the linear wall plates of the steel cofferdam, the at least two long bored pile steel casings are respectively arranged under two arc-shaped ends of the steel cofferdam along the bridge direction, the steel casings are fixedly connected by I-shaped steel, a group of Bailey beams (3) which are connected with the steel casings are respectively arranged at two sides of the linear wall plates of the steel cofferdam, and plugging plates (8) are arranged at two ends of each steel casing in a sealing manner. The steel cofferdam assembled floating platform is simple in structure, large in area, shallow in immersion depth, strong in antidumping capability, and high in safety and reliability; and in addition, due to the fact that main components of the steel cofferdam assembled floating platform are revolving materials and components required in the subsequent construction and can be repeatedly used, the construction cost can be greatly reduced.
Description
Technical field
The utility model relates to a kind of floating platform, and particularly a kind of job platform for steel cofferdam assembly unit, transportation by driving, entry, belong to technical field of bridge construction.
Background technology
Along with the development of China's economic construction and the rapid growth of transport need, bay, straits, the construction of leap rivers bridge are also more and more, the span of various bridge types breaks the world record in succession, indicates that the bridge construction technology of China is reached advanced world standards.Steel bushing (hanging) cofferdam is the important supporting facility of bridge deepwater foundation construction, and selecting steel cofferdam assembly unit, transportation by driving, the entry scheme of economical rationality according to different geological hydrology ambient conditionss is great difficult problem in construction.At present steel cofferdam mainly adopts harbour assembly unit on the bank, entry, but part work point is because orographic condition limits, construct a wharf more difficult or cost higher.
Summary of the invention
For the defects that exists in prior art, the utility model provides a kind of steel cofferdam assembly unit floating platform simple, that be easy to construct, can greatly reduce construction cost of making.
The technical scheme that the utility model adopts is: a kind of steel cofferdam assembly unit floating platform, it comprises straight line wallboard bottom that several are disposed on steel cofferdam both sides and perpendicular to the short drilled pile steel casing of steel cofferdam straight line wallboard and be separately positioned under steel cofferdam two arc ends along bridge at least two long drilled holes stake steel casings that arrange, be fixedly connected with by i iron between described steel casing, be respectively equipped with one group of Bailey beam that is connected with described steel casing in the both sides of steel cofferdam straight line wallboard, the sealed at both ends plugging plate that is provided with of described steel casing.
The utility model be utilize the drilled pile steel casing used in follow-up construction after the shutoff of two ends as floating drum, each floating drum forms buoyant device, by Bailey beam and i iron, each steel casing is connected to form floating platform, wherein Bailey beam is as supporting arrangement.The assembly unit of steel cofferdam, transportation by driving and entry all can utilize this floating platform to carry out operation.
Steel casing top in the outside that is positioned at steel cofferdam straight line wallboard also is provided with additional floating drum.The effect of additional floating drum be in floating drum does not have entry fully steel cofferdam gradually entry form the buoyancy switch transition from the floating stage.
In order to guarantee to connect reliably between the steel casing, in the utility model, be fixedly connected with by reinforcing bar arranged in a crossed manner between adjacent two steel casings.
In order to guarantee the bearing capacity of steel casing in construction, be provided with steel casing inner support in described steel casing.
The utility model passes through to adopt the drilled pile steel casing of two ends shutoff as floating drum, and by Bailey beam and i iron etc., each steel casing is connected to form floating platform, this floating platform area is large, draft is shallow, resistance to capsizing is strong, safety reliability is high, can satisfy steel cofferdam transportation by driving under varying environment, entry requirement.In addition, the utility model is simple in structure, but on-site consolidation, because its main member is circulation material and member required in follow-up construction, so its processing and fabricating cycle is short, is finished and can disassembles, and disassemble rear member and all can be used for successive projects, reuse, can greatly reduce steel consumption, can significantly reduce construction cost.

The specific embodiment
Below by embodiment and by reference to the accompanying drawings to the utility model further instruction:
As shown in accompanying drawing 1-2, a kind of steel cofferdam assembly unit floating platform, it comprises that mainly buoyant device, supporting arrangement and connector consist of.Wherein, buoyant device adopt follow-up drilled pile need with the steel casing make after the shutoff of two ends, form floating drum, mainly comprise short drilled pile steel casing 2 and long drilled holes stake steel casing 1, supporting arrangement is Bailey beam 3, connector is i iron 6 and reinforcing bar 5.Short drilled pile steel casing 2 has several, is disposed on the straight line wallboard bottom of steel cofferdam 4 both sides and perpendicular to steel cofferdam 4 straight line wallboard settings.Long drilled holes stake steel casing 1 is arranged under the arc end of steel cofferdam 4 both sides, and to setting, every side arranges two at least along bridge.Be fixedly connected with by i iron 6 between described steel casing.In order to guarantee to connect reliably between the steel casing, also can be fixed connection by reinforcing bar arranged in a crossed manner 5 between adjacent two steel casings.Be respectively equipped with one group of Bailey beam 3 in the both sides of each steel cofferdam 4 straight line wallboard, Bailey beam 3 is coupled to integral body with all steel casings, forms floating platform.
For provide steel cofferdam gradually entry from the buoyancy transition in floating stage, in the present embodiment, also be provided with additional floating drum 7 on the steel casing top in the outside that is positioned at steel cofferdam straight line wallboard.
As shown in accompanying drawing 3-4, be the schematic diagram of the end of the drilled pile steel casing in the present embodiment, the end of steel casing is established 8 pairs of steel casings of plugging plate and is carried out shutoff, forms the casing of sealing after the two ends shutoff of steel casing.
