钢筋混凝土沉井在顶管操作井施工中的应用

某顶管工程钢筋混凝土操作井采用不排水下沉沉井的施工方法。由于各个井体庞大,深度大,场区大多为软弱土层,地下水丰富,沉井在下沉施工过程中容易倾斜、偏位,下沉速度较难控制,采取可靠施工技术措施,取得了成功。介绍了下沉计算、施工准备、施工过程和纠偏措施等。

Application of reinforced concrete open caisson in pipe jacking working well construction

Undrained open caisson was employed in reinforced concrete open caisson in some pipe jacking engineering.Due to the large volume and deep depth of the open caisson,the soft soil stratum on most part of the engineering place,and the extensive underground water,the open caisson was easily to slope and deviate during the construction,and the sinking speed was also difficult to control.After using reliable engineering technique,the project was successful.This paper introduced the sinking calculation,constructio...
