摘要
深圳前湾过海管廊工程始发竖井采用沉井法施工,要穿越富水高水压地层、淤泥地层、粉质粘土、中密粗砾砂、残积土等不同地层。沉井直径为18m,深28.54m,属大型沉井。详细介绍了沉井的施工技术。
The launch shaft of Qianwan sub-sea shield-driven tunnel in Shenzhen is sunk by means of open caisson method. The sinking of the shaft penetrates through grounds with huge volume of high pressure water, as well as muddy layers, silty clay layers, layers consisting of medium-compact coarse gravels, residual soils and so on. With 18 m diameter and 28.54 m depth, the shaft is one of the large-scale shafts sunk by means of open caisson method. The article presents the sinking construction technology of the shaft in detail.
