| 摘 要： | 郑州市下穿中州大道矩形顶管隧道工程具有断面超大、覆土浅、4条隧道平行布置、净间距小等特点。为有效控制顶管掘进姿态,全方位介绍了顶管姿态控制、纠偏措施,并对铰接纠偏、双螺旋机出土、六刀盘操控、注浆纠偏、小间距推进控制等关键控制技术进行了详细阐述。实践表明,超大断面矩形顶管在浅覆土、小间距、多次扰动的情况下,采取铰接纠偏、双螺旋机出土、六刀盘操控、注浆纠偏等技术可有效控制顶管姿态。

| Abstract: | The tunnel crossing underneath Zhongzhou Avenue in Zhenzhou is constructed by rectangular pipe jacking machines. The tunnel has such features as super large cross section, shallow cover and 4 small spaced parallel tubes. In the paper, the technologies used to control the attitude of the pipe jacking machine, including deviation rectification by articulation cylinders, muck releasing by twin screw conveyors, different control modes of the six cutterheads, deviation rectification by grouting, control of the pipe jacking machine in the construction of the small spaced tunnel tubes, are described in detail. In the end, good effect has been achieved. |
