当盾构在封闭式竖井内移位调头时,采用钢珠重载移动装置,相比传统的解体、吊装再组装的方法,可以明显缩短工期,减少工程费用。此方法对于盾构移位调头施工有很大的借鉴意义。
When the shield is moved in the closed shaft, the steel ball heavy-duty moving device is adopted. Compared with the traditional disassembly and reassembly method, the construction period can be obviously shortened and the construction cost can be reduced. This method is of great reference to the construction of shield transfer.
