Embodiment Construction
[0040] The following is attached Figure 1-2 The application is described in further detail.
[0041] The embodiment of the present application discloses a concrete reinforcement structure. refer to figure 1 , the concrete reinforcement structure includes a bridge body 1 and a subgrade 2, and an abutment 11 is fixed under the bridge body 1 . The end of the bridge body 1 close to the subgrade 2 is provided with a board 3, which is hinged with the bridge body 1, and a reinforced concrete block 4 is provided under the board 3, and the reinforced concrete block 4 moves from the end close to the bridge body 1 to the side far away from the bridge body. The depth of one end of the body 1 gradually decreases, and the lower end of the reinforced concrete block 4 is arranged in a stepped shape. When the subgrade 2 subsides, the slab 3 can be rotated due to the hinge, thereby connecting the bridge body 1 and the subgrade 2, reducing the fracture situation, and setting the depth-changi...

The invention relates to a concrete reinforcing structure and a construction method, and belongs to the field of road and bridge constructions.The concrete reinforcing structure comprises a bridge body and a roadbed, a butt strap is arranged at the end, close to the roadbed, of the bridge body, the butt strap is hinged to the bridge body, and a reinforcing concrete block is arranged below the butt strap; the height of the reinforcing concrete block is gradually reduced from the end close to the bridge body to the end away from the bridge body, and reinforcing piles are arranged below the reinforcing concrete block and the roadbed. The transition slab can disperse descending of a roadbed and reduce breakage of the bridgehead position, the height of the reinforcing concrete block below the transition slab is gradually increased in the direction of the bridge body, the supporting effect can be gradually enhanced, the supporting effect below the transition slab close to the bridgehead position is improved, the disengaging situation of the transition slab close to the bridgehead position is reduced, and the reinforcing piles also reinforce the geology below the roadbed to reduce settlement, so that the phenomenon of bumping at the bridge head caused by local fracture is reduced.
Description
technical field [0001] The application relates to the field of road and bridge construction, in particular to a concrete reinforcement structure and a construction method. Background technique [0002] In the field of road and bridge construction, the transition section of road and bridge has always been a difficult and key point in the project. Due to the difference in settlement between the subgrade and the bridge, it is easy to cause local road surface drop and fracture, and the vehicle will jump when driving to the bridgehead section. [0003] The relevant construction process often adopts the bridge head slab, that is, one end of the bridge head slab is hinged to the bridge deck, so that the settlement can be dispersed to form an inclined plane, and it is also carried out by laying piles under the subgrade to fix it. [0004] In view of the related technologies mentioned above, the inventors found that in the actual construction process, since the space under the bridge...
