浅谈沉管法隧道接头处理

Discussion about Construction for Immersed Tunnel Joint

本文论述的沉管法隧道接头位置有:GINA带、Ω带、PC钢拉索、剪切键、橡胶支座等部件,每套部件都非常关键,各自具有独立的功能,接头处理施工就是把这些部件安装到各自的特定位置。GINA带、Ω带双保险沉管接头不漏水。在接头的水平方向、垂直方向和轴线方向都以柔性处理,并承载着水平、垂直和轴线三个方向的力。

There are many parts such as GINA belt, Omega band, PC steel cables, shear key, rubber bearings parts, etc. for immersed tunnel joints, this paper discusses how to mount these parts in position. GINA belt and Omega band ensures no water leakage of the joints. In a joint, flexible processing is carried out in the horizontal, vertical and axial directions to bear forces from the three directions.
