摘要
在上海轨道交通新一轮工程建设中,区间隧道直径由原来的6.2 m调整为6.6 m,为此,原有的盾构机需要进行扩径改造。结合盾构机小幅扩径改造设计,详细介绍了盾构机改造的总体方案,并分析了关键技术和改造价值,为后续盾构机改造提供借鉴。
In the new round of Shanghai rail transit construction,the interval tunnel has been enlarged from 6.2m to 6.6m in diameter.So,the former shield machine needs to be enlarged.Combined with the minor enlargement design of shield machine,the overall transformation scheme is introduced in detail,and the key technology and reconstruction value are analyzed,which provides references for the transformation of shield machine in the future.
