Two-way curved arch bridge floor broadening and reinforcing process method
The invention discloses a two-way curved arch bridge floor broadening and reinforcing process method. The two-way curved arch bridge floor broadening and reinforcing process method comprises the steps of (a) dismounting an original bridge floor concrete road surface and then respectively dismounting a part of curved cavity padding and side walls; (b) conducting bar embedding and concrete filling on two-way curved arch tiles on two sides; (c) installing steel bar concrete cushion blocks with inverted trapezoidal structures at the upper portions of the side walls and then casting a concrete filling-leveling layer on the top face of the curved cavity padding; (d) adopting a prestressed concrete cast-in-place cantilever mode to wholly casting concrete on the concrete filling-leveling layer and meanwhile arranging multiple expansion joints and contraction joints; (e) performing bridge floor conduction including a sidewalk system. By means of the two-way curved arch bridge floor broadening and reinforcing process method, the bearing performance of a bridge can be remarkably improved, bridge floor congestion can be effectively relieved, and meanwhile the two-way curved arch bridge floor broadening and reinforcing process method has the advantages of being convenient to construct, large in bridge floor broadening proportion, capable of remarkably improving side arch bearing capacity, good in reinforcing effect and the like.
