Composite reinforcing structure for main arch circle



The present invention discloses one kind composite reinforcing structure for main arch circle. The composite reinforcing structure consists of main arc circle and reinforcing reinforced concrete hoop layer, which includes mortar anchor rods inserted into the main arch circle and steel bar lattice around the main arch circle and connected with the mortar anchor rods. The in-situ deposited concrete on the steel bar lattice forms the reinforcing reinforced concrete hoop layer around the main arch circle. Adopting the technological scheme of the present invention can raise the bearing capacity of bridge by 10-50 %, and compared with re-building bridge, this has 80-90 % lower engineering cost and greatly shortened construction period.
