[0009]
The embodiment of the present application provides a construction method suitable for a bridge with a cable-stayed suspension cooperation system for highway and railway, so as to solve the problem of erecting side-span beams only after the construction of the main tower is completed in related technologies, and only sequential construction can be used. The side span and the main tower cannot be constructed simultaneously, which is unfavorable for the control of the construction period

The invention relates to a construction method suitable for a highway-railway dual-purpose cable-stayed suspension cooperative system bridge, and relates to the technical field of bridge construction. The construction method comprises the following steps: installing a first side span section on a lower cross beam of a main tower, and synchronously constructing an upper tower column on the lower cross beam of the main tower; hoisting a side span section to be erected and connecting same with the first side span section; jacking the erected side span sections so that the erected side span sections can move towards the side span side by a preset distance; hoisting and pushing are repeated until the first side span section is moved to the side pier, so that erection of the side span beam section is completed; after construction of the upper tower column is completed, hoisting the cable-stayed area beam section, and connecting same with the side span beam section; and erecting a main cable synchronously; hoisting the suspension area beam section and the cross area beam section, and closing the cross area beam section and the cable-stayed area beam section to form the cable-stayed and suspension cooperative system bridge. The erection of the side span beam section and the construction of the main tower can be synchronously carried out, the side span beam section does not need to be constructed after the construction of the main tower is completed, and the construction period of a key line is saved through the synchronous construction of the tower and the beam.
Description
technical field [0001] The application relates to the technical field of bridge construction, and in particular to a construction method suitable for a bridge with a cable-stayed suspension cooperative system for highway and railway. Background technique [0002] With the rapid development of bridge construction, since the cable-stayed-suspension cooperative system bridge has the advantages of high rigidity of cable-stayed bridges and strong spanning capacity of suspension bridges, the main tower is lower than that of cable-stayed bridges with the same span, and the dimensions of main cables and anchors are lower than those of cable-stayed bridges with the same span. Suspension bridges are small, so cable-stayed-suspension cooperative system bridges are the preferred solution for long-span road-rail bridges. [0003] Due to the special structure of the cable-stayed-suspension cooperative system bridge, the upper structure includes not only the anchorage, main cable, suspende...
