Pier top position regulating system for large-span steel truss arch bridge side pier and construction method
The invention discloses a pier top position regulating system for a large-span steel truss arch bridge side pier and a construction method. A back casting section is preserved on the pier top of the side pier, a pair of concrete support piers is separately cast at one side of the pier top of the side pier, in addition, the height of the concrete support piers is not higher than the back casting section, a steel truss is precisely positioned through the position regulating system, the position regulating system comprises a pad beam, a slide block, a position regulating mechanism and a support mechanism, the pad beam is fixedly arranged on the pier top of the side pier, the slide block is arranged on the pad beam, the position regulating mechanism comprises a first jack group used for moving the slide block and a second jack group used for regulating the height of the steel truss, the support mechanism is arranged in the middle part of the slide block and is used for supporting the steel truss, and a pad block is arranged between the support mechanism and the steel truss. The pier top position regulating system for the large-span steel truss arch bridge side pier has the advantages that the structure is compact and novel, the dismounting and the mounting are convenient, the pier top back casting section is creatively used, and a bracket beside the pier is saved.
