备注

以深圳地铁9号线有限场地下的盾构整体吊装应用为背景,提出盾构机整体吊装流程,探讨了整体吊装设备的结构性能,对其结构配置、牵引力系统提出改进意见. 针对在有限场地不能满足施作吊装设备基础条件的情况,分析采用均载板作为整体吊装设备基础施工的安全性,均载板最大Mises应力为24.58 MPa,最大变形为64 mm,满足强度及刚度要求. 实施结果表明,所选盾构机整体吊装设备及过程能满足可行性和安全性要求,提出的整体吊装措施安全可靠,可为类似工程提供借鉴.

In order to realize the integral hoisting of the tunnel boring machine in the limited space of Shenzhen Metro Line 9, a hoisting process of tunnel boring machine is put forward, and the security of hoisting equipment is analyzed. Some suggestions for the design of integral hoist equipment and traction system are presented. Regarding to the problem of the integral hoisting of tunnel boring machine under the condition of limited space where the foundation couldn't be conducted, a uniformly distributed load plate application is analyzed, and the results show that its maximum Mises stress is 24.58 MPa, and the maximum deformation is 64 mm, which could meet the requirements of strength and rigidity. Practice indicates that the hoisting process of tunnel boring machine and the measures of integral hoist can meet the needs of feasibility and safety. It provides a valuable reference for the similar projects.
