日前,中铁港航局深茂铁路指挥部运用新型水下不分散自密实混凝土技术,成功完成了潭江特大桥11号主墩双壁钢围堰封底施工。据悉,针对普通水下混凝土施工难度大、成本高的问题,深茂指挥部前期与清华大学展开合作,经过现场多次试验测试,成功研制出一种水下抗分散性能好、施工简便、节省成本、适合在铁路桥梁大仓面围堰封底施工中运用的水下
Recently, the deep-mao railroad command of China Railway Port-Aerospace Bureau, using the new underwater non-decentralized self-compacting concrete technology, successfully completed the construction of double-wall steel cofferdams for the 11th piers of Tanjiang Grand Bridge. It is reported that for the general construction of underwater concrete is difficult and costly problems, deep-mao headquarters early cooperation with Tsinghua University, after many field tests, successfully developed a good anti-dispersion underwater performance, construction is simple and save The cost is suitable for the submarine used in the construction of back cover cofferdam of railway bridge
