Open caisson reserved hole device and construction method
The invention discloses an open caisson reserved hole device and a construction method. The open caisson reserved hole device comprises a reserved water stop sleeve and an inner support inner mold. The reserved water stop casing pipe is used for being pre-buried in a steel reinforcement framework of the side wall of the open caisson and providing a hole. The inner supporting inner mold is used for blocking the hole in the sinking process of the open caisson so as to prevent external water and soil from entering the hole. According to the open caisson hole reserving device, the hole is reserved by pre-burying the reserved water stop sleeve in the open caisson prefabricating process, the potential quality and safety hazards caused by breaking the side wall of the open caisson after the open caisson sinks are avoided, the construction efficiency is improved, and the vertical pressure bearing capacity of the side wall of the open caisson is improved through the pre-buried reserved water stop sleeve. Besides, in the open caisson reserved hole device, the inner supporting inner mold blocks water and soil on the outer side of the side wall of the open caisson from gushing inwards, disassembly and assembly are convenient and fast, repeated turnover can be conducted, and cost is reduced.
本申请公开了一种沉井预留洞口装置及施工方法，沉井预留洞口装置包括预留止水套管和内支撑内模。预留止水套管用于预埋在沉井侧壁的钢筋骨架中，并提供洞口。内支撑内模用于在沉井下沉过程中封堵洞口，以阻断外部水土进入洞口内。通过本申请的沉井预留洞口装置，实现了在沉井预制过程中通过预埋预留止水套管留设洞口，避免了沉井下沉后破除沉井侧壁带来的质量和安全隐患，提高了施工功效，而且，预埋的预留止水套管增加了沉井侧壁竖向承压能力。另外，本申请的沉井预留洞口装置中，内支撑内模阻断了沉井侧壁外侧水土内涌，且拆装方便快捷，可进行多次周转，降低成本。
