Specifically, method of the U-shaped base to bridge pier column is lifted in the step 2 is：Two before and after U-shaped base
Side sets one group of hoisting bracket respectively, and every group of hoisting bracket is included positioned at the lifting entablature of U-shaped base top surface and positioned at U-shaped bottom
The lifting sill of seat bottom surface, is fixedly connected between lifting entablature and lifting sill by fining twisted steel, horizontal in lifting
Beam connects loop wheel machine by steel wire rope, and loop wheel machine removes hoisting bracket after lifting by crane U-shaped base to bridge pier column.
It is preferred that, the lifting entablature is parallel with lifting sill, and lifting entablature is with lifting sill along steel
The transverse width direction of reinforced concrete plate section is set.
Further, every group of hoisting bracket is respectively arranged on the left side and the right side a fining twisted steel, the essence
The middle part for rolling screw-thread steel is located in U-shaped base, and two ends are each passed through lifting entablature and lifting sill is connected with lifting nut.
Specifically, the left and right sides of the lifting entablature is respectively fixed with a steel wire rope lock, the loop wheel machine passes through
Steel wire rope is connected with steel wire rope lock.
Specifically, the side of flange plate support and edge of a wing plate bed die is set up in the step 3 in the left and right sides of U-shaped base
Method is：The upper and lower part of the flange plate support is fixed in U-shaped base by screw rod, edge of a wing plate bed die is layed in the wing
On the top surface of listrium support.
More specifically, the two ends of the screw rod are each passed through the side wall and flange plate support of U-shaped base and are connected with positioning spiral shell
It is female.
The beneficial effects of the invention are as follows：Beam body divide into U-shaped base, upper reinforcement by the construction method designed by the present invention
Three parts of concrete and flange plate are constructed respectively, and U-shaped base is prefabricated construction, and U-shaped base is hung using conventional cranes
Dress, lifting construction is easy.Upper reinforcement concrete is poured by the use of U-shaped base as bed die, while U-shaped base is also flange plate branch
Frame and building for edge of a wing plate bed die are provided the foundation, without setting up support, and in-situ precast can simultaneously be done with pier stud construction, not shadow
Ring the duration of critical circuits, short construction period.Auxiliary material include precast pedestal and a small amount of flange plate support, material consumption amount compared with
It is small；Beam body installation can be carried out using common crane, lifting cost is low.Solve the traffic under bridge and can not close, headroom of constructing will
The problem of beam body is constructed under conditions of asking higher, construction period nervous, valency is applied with good economy, practicality and market
Value.
