摘要
针对新孟河延伸拓浚工程常州市新北区黄山河立交地涵工程4m直径双排混凝土顶管顶进距离长、路径不直、穿越土层复杂、施工技术难度大的特点,通过对顶管中继间启动技术的研究与设计改进,增设远程自动化控制系统,实现了中继间远程联动启动,较好地减少地下管道内的施工人员人工操作,降低密闭空间内施工安全风险,同时也解决顶管施工中因人工启动中继间停顿时间过长引起摩阻力增加、顶进困难等系列问题。
Aiming at the characteristics of the 4m diameter double row concrete pipe jacking of Huangshan River interchange ground culvert project in Xinbei District,Changzhou City,the extension and dredging project of Xinmeng River,such as long jacking distance,non straight path,complex soil layer crossing and difficult construction technology,through the research and design improvement of the starting technology of the pipe jacking relay room,a remote automatic control system is added to realize the remote linkage start of the relay room,which can better reduce the manual operation of the construction personnel in the underground pipeline,reduce the construction safety risk in the confined space,and solve a series of problems such as the increase of friction and the difficulty of jacking due to the long pause time between manual start relays in the pipe jacking construction.
