In this article, authors introduce the construction pro cedure of steel pipe concrete of Wuhan Jianghan No.5 Arched Bridge whose span is 240m. This construction procedur e was finished with once pumping, jacking and pressed pouring under the situation of high temperature, lo ng distance transportation and high technical difficulty. Authors measured the development rules of concret e early-stage expansion rate and strength under sealed situation, and also recorded the change procedure of p umping pressure.
