本文结合广州地铁某区间盾构施工实际,从技术与实际应用角度对钢套筒施工辅助盾构机进洞工艺进行了全面研究与分析,简要介绍了钢套筒施工的注意事项,并对洞门破除的成本进行了预算。实践证明,盾构始发/到达洞口安装钢套筒能大大降低盾构始发/到达施工风险,并能节约施工成本,具有较高的经济效益和社会效益。 In this paper, a certain interval of Guangzhou Metro shield construction practice, from a technical and practical point of view of steel sleeve construction assisted shield machine into the hole for a comprehensive study and analysis of the process, a brief introduction of the steel sleeve construction considerations, and the hole The cost of breaking the door was budgeted. The practice proves that installing steel sleeves at the beginning of the shield / arriving at the entrance can greatly reduce the risk of starting / arrival of the shield and can save the construction cost and has high economic and social benefits.
