汾东商务区十号线3m雨水顶管施工技术

On survey of 3 m rainwater pipe jacking on No.10 Line at Fendong Commercial District

结合太原市汾东商务区十号线3 m雨水顶管的施工实例,介绍了雨水顶管工作井、接收井的施工工艺,并对其工作井内的主顶油缸进行了精确的推力计算,提出各区间中继环的设置参数,以指导今后类似工程施工。

Combining with the construction example of 3 m rainwater pipe jacking along the 10th Line at Fendong Commercial District of Taiyuan,the paper introduces the working well of the rainwater pipe jacking,and the construction craft of the receiving well,undertakes the accurate thrust calculation on the main top cylinder in the working well,and points out the design parameter for the relay ring at all sections,so as to direct similar projects in future.
