The method comprises manufacturing bridge pier, setting horizontal rotary device at the top of said bridge pier and accomplishing the construction for rotating beam body on the horizontal rotary device. By the technology project mentioned above, under the condition of higher bridge pier or larger cubage, the construction difficulty of bridge is decreased greatly and stability and safety of bridge construction can bridge rotation are guaranteed.
Description
Technical field
The present invention relates to a kind of bridge technology, relate in particular to a kind of rotating bridge and job practices thereof.
Background technology
Bridge may run into course lines such as highway in the operation, railway in erection process, therefore, in the bridge construction process, how need to solve under the situation that is not influencing highway, the normal operation of railway, finishes bridge erection.
At present, a kind of bridge is arranged, by the device of flatting turn being set between with bridge pier bottom and ground at the construction initial stage, make bridge pier and needing cross over the beam body in the course line zone beyond can be in the course line and finish construction in advance, rotate bridge pier and drive the beam body by the device of flatting turn then and rotate, cross over the course line, make the rotation place in place on the other end arrival opposite, course line of beam body, on permanent bridge pier or interim bridge pier, then, to flat turn device and to rotate the Liang Tiyi end at place in place fixing is finished bridge construction.
In realizing process of the present invention, the inventor finds that there is following problem at least in existing bridge construction:
1, because the bridge pier diameter is little, spandrel girder body, tower etc. to need the part of rotating, the pressure dispersal device need be set between bridge pier and tumbler, cause the bridge construction complexity, be unfavorable for construction;
When 2, the higher or bridge pier scale of construction was big when bridge pier, the weight of turning increased greatly, and causing rotating difficulty increases, and bridge pier is when higher, also can cause the poor stability of turning, and brought potential safety hazard for simultaneously the course line in the operation.
Summary of the invention
The purpose of the embodiment of the invention is the problem at the prior art existence, a kind of bridge and job practices thereof are proposed, with the bridge of realizing that a kind of beam body can rotate separately, guarantee higher at bridge pier or situation that the scale of construction is bigger under, stationarity and safety that the beam body rotates.
For achieving the above object, the embodiment of the invention provides a kind of bridge, comprises bridge pier and beam body, wherein, is provided with the device of flatting turn between described bridge pier and the beam body.By the technical program, bridge pier need not rotate, and only the beam body rotates around bridge pier, under or the situation that the scale of construction is bigger higher at bridge pier, greatly reduces the bridge construction difficulty, has guaranteed stationarity and safety that bridge construction and beam body rotate.
For achieving the above object, the embodiment of the invention also provides a kind of method for bridge construction, comprising:
The system bridge pier;
The device of flatting turn is set at described bridge pier top;
On the described device of flatting turn, finish the construction of waiting to change the beam body.
By the said method technical scheme, realized the preparation of the bridge that Liang Tike rotates separately, thereby guaranteed higher at bridge pier or situation that the scale of construction is bigger under, stationarity and safety that the beam body rotates.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
