Embodiment Construction
[0052] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. Based on the present invention All other embodiments obtained by persons of ordinary skill in the art without creative efforts, all belong to the scope of protection of the present invention.
[0053]In the actual bridge appearance inspection, the hinge joint damage of simply supported hollow slab girder bridges is very common, usually manifested as water seepage and hollowing out of the hinge joints, which means that the bridge's lateral connection performance has declined a lot, and it is facing the unfavorable situation of single girder stress at any time . The actual load test results also show that the transverse connection performance of simply supported hollow slab girder brid...
