Side-span closure section and cast-in-place section combining construction method
The invention discloses a side-span closure section and cast-in-place section combining construction method. The method includes the following steps that N corrugated steel web sections are constructed through hanging basket construction before side-span closure; a side pier cap beam support and a closure section support are erected on a receiving pier bearing platform, and hanging basket bottom baskets on the N corrugated steel web sections are moved forwards to the closure section support, so that the hanging basket bottom baskets are combined with the closure section support and the side pier cap beam support into an integrated support platform; corrugated steel webs on the closure section are installed one by one; steel ribs and pre-stress pipelines are installed on the integrated support platform; the time interval when the temperature change range is smallest and the temperature of concrete is raised after pouring in a day is selected, and meanwhile concrete of the closure section and the upper section of a side pier cap beam is poured; after the concrete of the closure section reaches the designed strength, pre-stress is tensioned, and side-span closure is completed. The method has the advantages that by the adoption of one-time closure, the overall side-span closure time is shortened by half a month, and time and construction cost are reduced.
