Method for mounting specially-shaped precast bridge decks on open lattice steel beams of arched bridge
The invention discloses a method for mounting specially-shaped precast bridge decks on open lattice steel beams of an arched bridge. The method comprises the following steps: conveying specially-shaped precast bridge decks onto side-span concrete beams at the tail parts of open lattice steel beams; laying steel beam slide rails on the open lattice steel beams and placing steel beam skid shoes on the steel beam slide rails; hoisting the specially-shaped precast bridge decks onto the steel beam skid shoes, and drawing the steel beam skid shoes to convey the specially-shaped precast bridge decks to a mid-span mounting position; adopting a small-sized hoisting frame to hoist the specially-shaped precast bridge decks, drawing out the steel beam skid shoes, dismantling steel beam slide rail segments at the mounting position, and laying down the specially-shaped precast bridge decks to complete mounting construction; drawing the unloaded steel beam skid shoes to specially-shaped precast bridge deck storage positions at the tail parts of the open lattice steel beams; and repeating the above steps to complete installation of all the specially-shaped precast bridge decks on the open lattice steel beams. The method is simple and practical in construction operation, greatly shortens the erection construction period of the bridge decks, ensures good safety and high quality and realizes economic profit maximization.
