上海人民路越江隧道工程掘进施工时,首次采用TM1158WSM型直径11.58m的泥水平衡式盾构机(以下简称盾构机)。掌握该盾构机中的泥浆循环系统调试与维修技术,是整个盾构施工成败的关键。本文通过对泥浆循环系统的组成与功能的阐述,着重分析在调试、施工中所产生的问题和故障,提出快速诊断故障的应对手段与维修措施,并对经验与要领加以总结。
Shanghai Renmin Road Tunnel construction of the tunnel excavation, the first time using TM1158WSM diameter of 11.58m mud-water balance shield machine (hereinafter referred to as shield machine). Grasp the shield drilling machine in the mud circulation system debugging and maintenance technology is the key to the success or failure of the entire shield construction. This paper elaborates the composition and function of the mud circulation system, focuses on the problems and faults in the debugging and construction, puts forward the measures and maintenance measures to quickly diagnose the faults, and sums up the experience and essentials.
