狮子洋隧道是国内首次在复合地层中采用大直径泥水盾构长距离掘进,包括全断面软土地层、软硬不均地层、全断面硬岩地层,其中软硬不均地层采取带压进仓的方式进行刀具检修。本文结合施工情况,阐述了带压进仓的方法。
Shiziyang tunnel is the first take large diameter sl-urry shield with long tunneling distances in composite form-ation, which include the ful-face soft soil layer, uneven strata, ful-face hard rock formations, which take uneven formation warehouse entry with pressure approach to tool maintenance. In this article, the author combines with construction situation and elaborates the approach of warehouse entry with pressure.
