(3) paving sliding rails on the support and the top surface of the cover beam in the transverse bridge direction; a vertical jack is arranged on the bent cap;
(4) two rows of sliding devices are welded at the bottom of the steel box girder in the transverse bridge direction, and the distance between the two rows of sliding devices is consistent with the distance between the sliding rails on two adjacent bent caps; welding two anchor plates on one side of the steel box girder, wherein the distance between the two anchor plates is consistent with the distance between the counter-force seats on the two adjacent bent girders;
(5) hoisting the steel box girder to the supports corresponding to the two adjacent piers by using a crane, and respectively supporting the two rows of sliding devices at the bottom of the steel box girder on the slide rails at the tops of the two supports;
(6) connecting a steel strand between the anchor plate and the counter-force seat, wherein one end of the steel strand is anchored with the anchor plate, the other end of the steel strand passes through the counter-force seat and then passes through a center-penetrating jack, and a base of the center-penetrating jack is supported on the side wall of the counter-force seat;
(7) starting the center-penetrating jack, and drawing the steel box girder to move above the cover girder along the slide rail through the steel strand;
(8) and starting a vertical jack on the cover beam to lift the steel box beam upwards, enabling a sliding device at the bottom of the steel box beam to leave the sliding rail, cutting off the sliding device, returning oil by the vertical jack, and dropping the steel box beam onto a support at the bottom of the cover beam to finish the installation of the steel box beam.
According to the invention, the steel box girders are installed in a lateral sliding mode, so that the problem that the lower layer steel box girder cannot be directly hoisted when the upper layer bridge steel box girder and the lower layer bridge steel box girder are constructed simultaneously is solved, the installation of the lower layer steel box girder is not influenced by the upper layer construction, and the construction progress can be ensured.
