大口径排水管道顶管施工技术

Construction Technology of Prop Pipelining with Large Diameter Discharge Pipe

结合武汉五环大道大口径排水管道顶管工程实例,研究和分析了大口径管道顶管施工方案的选择及顶力计算、工作坑支护和顶管施工过程中的技术难点,阐述了顶管施工的方法及技术措施。

Based on the case project of prop pipelining with large diameter discharge pipe in Fifth Ring Road in Wuhan, the pa- per studies and analyzes selection of construction plan, jacking force calculation and pit support of prop pipelining with large diameter. In addition, problems and technical difficulties during prop pipelining are also discussed. Finally, methods of prop pipelining and technical countermeasures are illustrated.
