In detailed description of the invention, two Dun Ding of described transition bridge pier are provided with hydraulic pressure and shore and temporary support, and hydraulic pressure shores the both sides of the pier cushion cap laying respectively at each Dun Ding with temporary support.
In one embodiment, described connection cross-bridges is symmetrical arranged two groups of hydraulic pressure and shores and temporary support, the both sides, front and back often organizing temporary support arrange two hydraulic pressure and shore.
In one embodiment, described rigid contact sliding part comprises the sliding way steel plate, tetrafluoro plate, corrosion resistant plate and the glide path steel plate that superpose setting successively, and described glide path steel plate to be connected with top of bridge pier end face by cushion block and to arrange.
In another embodiment, the surrounding of described rigid contact sliding part is provided with slideway block, described slideway block slides arrange and adjusts beam fluid pressure drive device, and this tune beam fluid pressure drive device level is arranged to driving temporary support.
In one embodiment, described tune beam fluid pressure drive device is the hydraulic jack that horizontal four direction is arranged respectively.
In one embodiment, the support portion of described temporary support comprises a concrete pedestal, and described this concrete pedestal of tune beam fluid pressure drive device horizontal drive is arranged.
Again in an embodiment, the upper end of described concrete pedestal is provided with a rigidity sandbox, and this rigidity sandbox side is provided with sand export, large-scale steel box-girder described in the top pushing tow of this rigidity sandbox.
In another embodiment, the upper end of described rigidity sandbox is superimposed with adjustment billet, and billet upper end is provided with rubber shock-absorbing plate.
The installation positioning system of this large-scale steel box-girder is shored and temporary support by the hydraulic pressure arranged at the Dun Ding of transition bridge pier, just position adjustment is carried out in the lifting moving process of large-scale girder steel, ensure the stability of steel box-girder in lifting moving process, thus effectively improve lifting effect.Hydraulic pressure is shored distribution and is arranged the load-bearing played and alleviate temporary support positioning.The hydraulic pressure be positioned on the connection cross-bridges installing bridge pier shores the fine adjustment carrying out with temporary support installing, the tune beam fluid pressure drive device that the surrounding of temporary support is arranged optionally can drive temporary support from four direction, makes temporary support rely on the vertical or horizontal fine adjustment of the realization of rigid contact sliding part and large-scale steel box-girder.
The beneficial effects of the utility model are, the installation positioning system structure design of this large-scale steel box-girder rationally, when can install large-scale steel box-girder and precisely positioning after installing, it is easy to operate, effectively can keep the stability of steel box-girder, cost is low and can realize the flexible modulation of all directions.This device effectively simplifies the Operating Complexity that lifting is installed, and significantly improves efficiency of installing and transpose.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
