Abstract

The invention provides a construction method for erecting steel girders, which belongs to the technical field of bridge construction. After the support is assembled, it is floated to the temporary support pier with a floating body, water is injected into the floating body to sink the floating body, and the support falls on the temporary support pier. , withdraw the floating body, and then install the steel beam on the support. After the steel beam is installed, use the supporting device to lift the steel beam and separate it from the support. And float the support to the next steel bridge construction place, the construction method of erecting the steel girder provided by the present invention, the floating body can realize the lifting and falling action simply and quickly, the support is transported to the temporary pier by the floating body, and the support is moved out with the floating body after the steel beam is erected To another working point, so that the support can continue to use, this way simplifies the working process of erecting steel beams, and improves the stability of erecting steel beams.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and more specifically relates to a construction method for erecting steel girders. Background technique [0002] Steel bridges are widely built because of their high rigidity, short construction period, and easy repair. Common methods for erecting steel girders in water include dragging method, full-support method, and floating method. Among them, the dragging method has a long construction period; when assembling steel girders with full support, it is necessary to set up temporary piers between bridge spans, such as driving multiple rows of steel pipe piles, and it is necessary to pull out steel pipe piles and dismantle the supports many times. The cost is high; the floating method needs to lift the steel beam to a certain height, and the stability cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to provide a construction method for e...
