Abstract： The project of diverting water from Hanjiang River to Weihe River through the hinterland of Qinling Mountains has unfavorable geological conditions such as large buried depth， high ground stress and high strength hard rock. So the Lingnan TBM equipment in excavation under high load condition for a long time， the damage of the key parts of the equipment is very serious and the oil leakage of TBM support boots oil cylinder is occurred. In this article， through the analysis and study on TBM equipment support boots cylinder damage and its influence， it formulated the boots cylinder replacement scheme and concrete operation methods， and analyzed the difficult point of the process of change， fast and safe in confined spaces hold boots cylinder transportation， disassembly and replacement. It ensured the reliable operation of Lingnan TBM equipment supporting oil cylinder in the process of excavation in poor geological environment， improved the utilization rate and working performance of TBM equipment and reduced the cost and expenses and equipment failure rate. It also had provided a reference for the replacement and repair of TBM boot cylinder in narrow space in China.

我国水资源区域分布极不均衡，随着国内经济的快速发展，水资源的短缺已严重制约一些地区的经济发展，为此一大批跨流域长距离的引水工程相继动工建设。输水隧洞采用TBM设备掘进越来越普遍，尤其是在一些长距离、高地应力、大埋深等施工难度较大的隧洞应用较多。与常规的钻爆法施工相比，TBM施工法明显具有工期短、速度快、施工环境好、整体效益高等特点。为确保施工过程中TBM设备高效、安全运行，设备重点部位零部件的可靠性要求标准很高，撑靴油缸是TBM设备比较重要的零部件，其为TBM设备的推进产生支撐反力，能使刀盘旋转中出现的大扭矩得以抵消，其性能的好坏对整个TBM设备运行的质量、效率起到关键作用。……
