摘要
一般情况下,双沉井施工为相邻两井同时下沉,通过控制两座沉井的下沉速度及下沉姿态来保证沉井准确就位.本工程沉井施工方式与通常情况有所差异,在循环水泵房沉井施工完毕后,方进行紧邻的进水流道沉井施工;就进水流道沉井设计、施工中所遇到的问题及解决办法进行阐述,供大家探讨.
Generally,two neighboring open caissons of dual open caisson should be sunk at the same time,in order to ensure the open caissons can be sunk to design position by controlling the sinking speed and sinking posture of open caissons.In this project,one open caisson of the dual open caisson has been sunk to design position,and then the other caisson begins to sink.This paper attempts to summarize and discuss the experiences for design and construction of the dual open caisson.
