Embodiment
[0028] Such as figure 1 As shown in -4, the embodiment of the present invention provides a road bridge reinforcement construction process, which uses a road bridge support device, the road bridge support device includes a foundation 1, a bridge body 2, and a bridge pier 5, and adopts the above road bridge support device The process of strengthening highway bridges includes the following steps:
[0029] a. Assembling the main frame: use fixing bolts to fix a plurality of mounting plates 3 on the upper end of the foundation 1 and the lower end of the bridge body 2, and weld the fixing seats 4 at one end of the plurality of mounting plates 3, and install them inside the plurality of fixing seats 4. Use a pin to connect the first connection block 6, use a pin to connect the second connection block 7 between a plurality of up and down adjacent first connection blocks 6, and weld the drive plate 17 on one side of the plurality of second connection blocks 7;
[0030] B, drive instal...

The invention provides a highway bridge reinforcing construction process, which uses a highway bridge supporting device, and the highway bridge supporting device comprises a foundation, a bridge body and a bridge pier, the process for reinforcing the highway bridge through the highway bridge supporting device comprises the following steps of assembling the main body frame, installing the driving device, starting the supporting device, and expanding cracks for filling. According to the bridge pier crack repairing device, the shell is supported through the highway bridge supporting device arranged between the shell and the foundation, the protection effect can be achieved when bridge pier cracks are repaired, the cracks of the bridge pier cracks are expanded, steel bars are planted in the expanded gaps, and finally the gaps are filled with concrete, so that the cracks can be repaired more firmly; the service life of the reinforced pier is longer.
Description
technical field [0001] The invention relates to the technical field of road bridge reinforcement, in particular to a road bridge reinforcement construction technology. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. Bridges are generally composed of superstructure, substructure, supports and auxiliary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; The force transmission device installed at the supporting place between the span structure and the bridge pier or abutment; the auxiliary structures refer to the bridge head board, conical s...
