Construction method for laying suspension bridge catwalk
The invention relates to a construction method for laying a suspension bridge catwalk. After erecting and sag adjusting of catwalk load-bearing cables and catwalk portal load-bearing cables are completed, the process of laying a catwalk surface layer is carried out, a basket is installed at the portions, closest to a bridge, of the load-bearing cables through a support, and steel wire gauze slices, anti-skidding planks and other needed facilities are lifted and placed in the basket through a lifting device. The basket serves as a stacking platform and also serves as an operating platform used for installing the steel wire gauze slices and the anti-skidding planks. A winch is installed on a tower, the steel wire gauze slices installed by workers are sequentially lifted in the mode that the winch winds steel wire ropes, and every time the steel wire ropes move by the distance of one steel wire gauze slice, the workers install one new slice and connect the new slice with the former slice, so that laying of the catwalk gauze face from the lower end to the upper end is completed. Similarly, laying of the other side is completed with the method.
