Description
Technical field
The utility model relates to a kind of deep water bridge foundation construction, particularly deep water bridge foundation construction multifunctional hole-drilling platform top.
Background technology
Along with China transport development Tongjiang reaches advancing by leaps and bounds of maritime works's journey, deep water multi-column pier foundation, highrise pile cap obtain very using widely as the main base form of striding river, Oversea bridge.
The construction traditional method on such basis is at present: build drilling platform construction drill castinplace pile in water, after pile foundation construction finishes, remove the drilling platform in the bearing platform construction scope, and the steel box is installed is carried out the construction of cushion cap.This kind job practices must be removed drilling platform, and reinstall steel box base plate after pile foundation construction is finished, and again as support, carries out the assembly unit of other members such as steel box wallboard, cause the waste of lot of materials, and the duration is longer.
Summary of the invention
The purpose of this utility model provides a kind of deep water bridge foundation construction multifunctional hole-drilling platform top that reduces construction cost, accelerating construction progress.
The purpose of this utility model is to realize like this, deep water bridge foundation construction multifunctional hole-drilling platform top, it is characterized in that: comprise girder, secondary beam, collar tie beam, riblet, panel at least, girder, secondary beam are the twin beams body, girder and the vertical in length and breadth reticulate body that connects and composes of secondary beam; Connect collar tie beam in the reticulate body grid, reticulate body upper surface fixed panel connects riblet between the girder of twin beams body and the secondary beam; Make girder, secondary beam, collar tie beam, riblet, panel-shaped be integral platform; Platform again with steel casing or steel pipe pile on the platform top that is provided with support the distribution beam top and be connected.
Describedly be integral platform by girder, secondary beam, collar tie beam, riblet, panel-shaped and be higher than more than the working water level 2m.
The utility model has the advantages that: top board double as box base plate, improved the drilling platform form of in the past supporting by the temporary steel pile tube, adopt the steel casing to support.The type platform can be in the drilled pile construction stage support platform as rig and placing of material, satisfy the drilling construction requirement, can transfer to design elevation directly as steel box base plate after drilling construction is finished again, play the bottom concrete cast and rely on the effect of structure.Use this multifunctional hole-drilling platform top, not only can be in the deep water foundation work progress, save steel box base plate and a large amount of temporory structuries and the material supporting with it, and reduce at pile foundation construction and bearing platform construction transition stage and face the operation that repeated structure is removed and installed greatly, a large amount of durations have been saved, for in the extensive deepwater high pile bearing platform construction of bridge, reduce aspects such as construction cost, accelerating construction progress, played significant effect and effect.

Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is the double box base plate facade arrangement diagram of doing of drilling platform top board;
Fig. 2 is the double box base plate plane arrangement diagram of doing of drilling platform top board;
Fig. 3 is the A portion enlarged drawing among Fig. 1.
Among the figure: 1, drilling platform top board; 2, box base plate; 3, steel casing; 4, platform top supports distribution beam; 5, working platform; 6, rig; 7, steel box wallboard; 8, support in the steel box; 9, back cover concrete; 10, base plate suspension rod; 11, steel pipe pile; 101, girder; 102, secondary beam; 103, collar tie beam; 104, riblet; 105, panel.
The specific embodiment
As shown in figures 1 and 3, deep water bridge foundation construction multifunctional hole-drilling platform top comprises girder 101, secondary beam 102, collar tie beam 103, riblet 104, panel 105, girder 101, secondary beam 102 are the twin beams body, girder 101 and the vertical in length and breadth reticulate body that connects and composes of secondary beam 102; Connect collar tie beam 103 in the reticulate body grid,, adopt steel casing 3 to support as vertical owing to boring position, hole is set at steel casing 3 places.Reticulate body upper surface fixed panel 105 connects riblet 104 between the girder 101 of twin beams body and the secondary beam 102; Make girder 101, secondary beam 102, collar tie beam 103, riblet 104, panel 105 form the one platform.
As shown in Figure 2, form the one platform by girder 101, secondary beam 102, collar tie beam 103, riblet 104, panel 105, weld with working platform 5 around the one platform, the platform that is provided with on working platform 5 and steel casing 3 or the steel pipe pile 11 is worked on regular shifts and is supported distribution beam 4 (or being called bracket) top overlap joint, the vertical one platform that supports of steel casing 3 conducts.Consider drilling construction load and bottom concrete cast load in the design of platform.In the bored pile construction stage, 1 on drilling platform top board is held in steel and protects the upper end platform top that sets in advance of outer wall and support on the distribution beam 4 (support bracket).After bored pile is executed end, on steel casing 3 tops place system under the suspention is installed, at first drilling platform top board 1 is mentioned certain altitude, the platform top of cutting off drilling platform top board 1 below again supports distribution beam 4 (bracket), the platform top of transferring certain altitude to the water surface then supports on the distribution beam 4 (bracket), as the base plate of steel box.
In whole foundation construction process, to consider as a whole, drilling platform top board 1 function is taken into account drilling construction requirement and steel box back cover concrete cast requirement.
