【摘要】：随着施工工艺的不断进步,盾构工程施工已经成为城市地下交通工程中使用范围最广、频率最高的工程技术。但是盾构工程在成本造价消耗方面比较巨大,施工工艺控制点较多,若施工工艺控制把控得不好,容易发生事故造成无法估量的损失。探讨了实施盾构工程时所采用的施工工艺技术及控制点,包括盾构掘进模式选择、盾构始发施工、控制地面沉降、盾构推进参数设置、渣土塑流化改良、盾构掘进方向管控、盾尾的油脂压注、管片拼装工艺、盾构同步、二次注浆、渣土的运输、盾构机到达接收施工。还对盾构施工造价管理相关要点作出了简单的理顺,其造价管理措施包括施工前明确技术工艺环节、落实交底;做好统筹全局、优化安排;强化施工中成本管理。
[Abstract]:With the continuous progress of construction technology, shield construction has become the most widely used and frequently used engineering technology in urban underground traffic engineering. However, the cost consumption of shield engineering is huge, and there are many control points of construction technology. If the construction technology control is not well controlled, it is easy to cause inestimable losses due to accidents. This paper discusses the construction technology and control points used in the implementation of shield engineering, including shield tunneling mode selection, shield initiation construction, control of land subsidence, shield propulsion parameter setting, slag soil plastic fluidization improvement, shield tunneling direction control, oil injection at the end of shield, segment assembly technology, shield synchronization, secondary grouting, slag transportation, shield machine arrival and reception construction. In addition, the key points of shield construction cost management are simply straightened out, and the cost management measures include defining the technical and technological links before construction, implementing the bottom line, doing a good job of overall planning, optimizing the arrangement, and strengthening the cost management in construction.
