Fabricated open caisson and construction method thereof
The invention discloses a fabricated open caisson and a construction method thereof. The fabricated open caisson comprises a caisson body, a locking opening structure arranged at the upper end of the caisson body and a steel-encased blade foot ring arranged at the lower end of the caisson body. The well body comprises a standard shaft and/or a special shaft used for arranging a communication channel; a plurality of preset connecting pieces are arranged on the inner wall of the standard shaft and/or the special shaft at intervals and used for being connected with the secondary lining structure. The device has multiple functions and is wide in application range; the construction efficiency is high, and the overall anti-floating stability is good; manual underwater operation can be avoided, and the construction safety is improved; according to the ground open caisson structure and the construction method thereof, rapid communication construction of the shield tunnel and the mechanically-built open caisson can be successfully achieved, and the construction efficiency and safety are improved.
本发明公开了一种装配式沉井及其施工方法，包括井体、设置在井体上端的锁口结构和设置在井体下端的外包钢刃脚环；所述井体包括标准井筒和/或用于设置联通道的特殊井筒；标准井筒和/或特殊井筒内壁间隔设有若干预设连接件用于连接二次衬砌结构。本发明具有多功能应用，适用范围较广；具有施工效率高、整体抗浮稳定性好的优点；本发明可避免人工水下作业，提高施工安全性；本发明所属地沉井结构及其施工方法，可以成功解决盾构隧道与机械化建造沉井的快速联通施工，提高施工效率和安全性。
