Caisson water inlet control method
The invention discloses a caisson water inlet control method, and belongs to the technical field of caisson construction. The method comprises the steps that a steel pipe and a first steel plate with an opening are pre-buried in the outer wall of the caisson, the opening of the first steel plate is aligned with a steel pipe opening, the first steel plate is tightly attached to the inner side of the caisson outer mold, and the caisson outer mold is dismantled after pouring of the bottom layer of the caisson is completed. The surface of the first steel plate is cleaned, a rotating shaft sleeve is fixed on the first steel plate, a rotating shaft fixed with a second steel plate is inserted, and the second steel plate is rotationally connected with the first steel plate. A bolt is welded in the middle of the second steel plate, a first rubber plate with a hole matched with the bolt is adhered to the middle of the second steel plate, a third steel plate with a hole matched with the bolt is mounted on the surface of the first rubber plate and is fixed by a nut, and a valve pull rod is fixed at the bottom of the second steel plate. The caisson is transported to a construction site, the pulling rope is installed, the semi-submersible barge dives until the caisson stably draws water during floating, the pulling rope is lifted to open the valve, and when the calculated stable water depth of the caisson during floating is reached, the pulling rope is loosened, and the valve is closed through water pressure. The caisson water inlet control method is easy and convenient to operate, a technician does not need to enter water to open and close the valve, and the caisson installation efficiency and safety are improved.
本发明公开了一种沉箱进水控制方法，属于沉箱施工技术领域。该方法为：在沉箱外墙预埋钢管和设有开孔的第一钢板，第一钢板的开孔对齐钢管口，第一钢板与沉箱外模内侧紧密贴合，沉箱底层浇筑完成后拆除沉箱外模。清理第一钢板表面，并在其上固定转轴套，插入固定有第二钢板的转轴，第二钢板与第一钢板转动连接。在第二钢板中间焊接螺栓并粘接设有与螺栓相适应开孔的第一橡胶板，在第一橡胶板表面安装设有与螺栓相适应开孔的第三钢板，使用螺母固定，在第二钢板的底部固定阀门拉杆。沉箱运至施工现场，安装牵引绳，半潜驳下潜至沉箱浮游稳定吃水，提升牵引绳使阀门开启，达到计算沉箱浮游稳定水深时，松开牵引绳，水压使阀门关闭。本发明提供的沉箱进水控制方法操作简便，无需技术人员下水启闭阀门，提高了沉箱安装的效率和安全性。
