大口径超长距离钢筋混凝土顶管施工技术

Construction Technology of Reinforced Concrete Pipe-jacking with Large Diameter and Ultra-long Distance

结合上海泰和污水处理厂钢筋混凝土顶管工程,介绍3000 mm大口径钢筋混凝土管在超长距离顶管施工过程中进出洞、长距离顶进、下穿箱涵和地铁、曲线线形控制等方面的关键技术,并详细总结了顶管顶进施工中经优选后易于操作的技术应对措施,可为类似工程施工提供借鉴和参考。

Combined with the reinforced concrete pipe-jacking project of Shanghai Taihe Wastewater Treatment Plant,the key technology of using 3000 mm large diameter reinforced concrete pipe in the process of long distance pipe jacking construction in and out of the hole,ultra long-distance jacking,crossing box culvert and subway,the curve control,etc.is introduced,and technical optimal countermeasures for easy operation in pipe-jacking construction is summarized in detail,which can provide reference for similar engineering construction.
