Detachable rolling sinking type open caisson structure and construction process
The invention discloses a detachable rolling sinking type open caisson structure and a process method, and belongs to the technical field of open caisson engineering. According to the technical scheme, the detachable rolling sinking type open caisson structure comprises an open caisson formed by pouring an upper open caisson section and a lower open caisson section, wherein a plurality of rolling devices detachably connected with the open caisson are arranged in the circumferential direction of the open caisson at intervals, each rolling device comprises at least two vertical plates attached to the outer wall of the open caisson, and a plurality of rotating rollers which are parallel to one another and distributed on the outer side of the lower open caisson section are connected between the adjacent vertical plates. According to the detachable rolling sinking type open caisson structure and the process method, the detachable rolling devices are arranged on the outer side wall of the lower open caisson section, so that the side resistance in the whole open caisson sinking process is reduced; and the pot-shaped excavation mode is matched, so that the speed of the open caisson during initial sinking is prevented from being too high, and the controllability of construction is improved.
本发明公开了一种可拆卸滚动下沉式沉井结构及工艺方法，属于沉井工程技术领域，其技术方案为：包括由上节沉井段和下节沉井段浇筑而成的沉井，沉井周向间隔设置多个与之可拆卸连接的滚动装置，所述滚动装置包括至少两个与沉井外壁贴合的竖板，相邻竖板之间连接有多个相互平行且分布于下节沉井段外侧的回转辊。本发明通过在下节沉井段外侧壁设置可拆卸的滚动装置，减小整个沉井下沉过程中的侧阻力；且配合锅型开挖方式避免沉井在初始下沉时速度过快，提高施工的可控性。
