本文通过对已完成深圳地铁施工的复合土压平衡盾构机(适应φ6000 mm管片外径)进行适应性升级改造,使其适应了上海地铁施工要求(适应φ6200 mm管片外径)。现将实施过程简介如下:
In this paper, the composite earth pressure balance shield machine (adapted to φ6000 mm segment OD) that has completed the construction of Shenzhen Metro has been adaptively upgraded and adapted to the construction requirements of Shanghai Metro (adapted to φ6200 mm segment OD). Now the implementation process is as follows:
