| description | A lifting method for a frame bridge box body comprises the steps of carrying out joint cleaning on settlement joints in a picking mode, then using a water drill to drill holes downwards at the positions and injecting grout to separate U-shaped grooves from the box body; forming grout stopping walls in soil bodies at the positions of the front end and the rear end of the box body; forming a plurality of reinforcing holes, lifting holes and complementary holes in the rear portion, the front portion and the middle of a bottom plate of the box body respectively; utilizing a grout injecting machine to carry out grouting operation on the holes and the like. By means of the lifting method for the frame bridge box body, approaches on the two sides of the box body are not needed to be disassembled, and the use amount of cement is saved by 20% compared with an existing method so that the construction cost can be greatly reduced, the construction period can be shortened, and the construction difficulty can further be reduced. Meanwhile, the lifting method for the frame bridge box body has the advantages of being high in operation performance and safety performance and the like, and has remarkable advancement and practicality. |
