Content Introduction [Overview] The original bridge and the split bridge are connected by the split width method of "the upper hollow slab is hinged and the lower structure is not connected". The middle span spans the cement road between villages with a width of 6 meters. The clearance of the crossed road under the original bridge is 3.8 meters. Vehicle load class: highway - Class I bridge deck width: 42 meters in full width. The distance between the two bridges is 1 meter. Seismic peak acceleration: 0.10g. Design safety class: the original bridge of Class II is designed as a medium bridge of 3-13 meters, with an intersection angle of 90 degrees. Total length of bridge: 43.04m Superstructure: prestressed simply supported hollow slab bridge deck Continuous substructure: column pier and abutment (three column) Bored cast-in-place pile foundation Bridge bearing: plate rubber bearing Total thickness of existing bridge deck pavement: 16cm Expansion joint is a 60 type expansion device that was specially replaced for maintenance in 2008. According to the same structural form as the original bridge, combined with the terrain and the horizontal and vertical planes of the route, the bridge is designed to have a span of 3-13m, an intersection angle of 90o, and a central stake number of K382+859.978. The bridge starts at K382+838.458 and ends at K382+881.498. The clearance of the route to be routed shall be controlled as 4.0m. Structure and design points: the structural type of the spliced bridge shall be as consistent as possible with the original bridge, and the stress state of the original bridge and the integrity of the bridge after widening shall be maintained. The new and old bridges are widened in a way that they are not connected from top to bottom. The capping beam and ear wall of the original pier and abutment are 32cm within the newly widened 8m subgrade. In order not to damage the original abutment, the transverse dimension of the capping beam is 766cm in this design (newly widened), leaving a 2cm gap between the capping beam and the original bridge. Anchor bolts and stop blocks shall be set at the top of the pier and abutment to enhance the limiting measures, and rubber plates shall be pasted on the stops on both sides to play the role of seismic buffer between the plates.
