在快速发展的城市轨道交通施工中,盾构区间联络通道的施工一般采用冻结技术加固联络通道部位的土体。由于冻结加固土体施工工期较长,因此联络通道的施工工期对盾构隧道的工期影响很大。如何正确处理盾构施工、联络通道施工、铺轨施工三者之间的关系,在不同的工况条件下,采取相应 In the rapid development of urban rail transit construction, the construction of the liaison channel in the shield zone generally uses freezing technology to reinforce the soil at the contact channel. Due to the long construction period of the frozen reinforced soil, the construction period of the contact channel has a great impact on the construction period of the shield tunnel. How to deal with the relationship between shield construction, communication channel construction and laying construction properly, under different working conditions, take corresponding measures
