Underwater sub-warehouse bottom sealing construction method for steel open caisson
The invention discloses a steel open caisson underwater separated bin bottom sealing construction method. The method comprises the following steps that movable baffles are arranged at the positions of an outer blade foot and an inner blade foot of a steel open caisson; the steel open caisson comprises a plurality of first shaft bodies evenly arranged in the circumferential direction and a plurality of second shaft bodies evenly arranged in the circumferential direction, the number of the first shaft bodies is sixteen, and the number of the second shaft bodies is four. The outer blade foot and the inner blade foot are located at the outer wall bottom and the inner wall bottom of the first shaft. The steel open caisson is sunk to the foundation pit, the movable baffle is lowered to the seabed, and the bottom of the outer wall and the bottom of the inner wall of the first shaft are sealed; the four first shafts are subjected to bottom sealing and edge grouting; the four first shaft bodies are symmetrically arranged about the transverse bridge direction center line and the longitudinal bridge direction center line of the steel open caisson. The side cable side shaft is subjected to bottom sealing and edge grouting; sealing the bottom of a shaft on the main cable side and grouting a blade foot; and the second shaft is subjected to bottom sealing and edge grouting. According to the method, the underwater bottom sealing quality of the steel open caisson can be guaranteed, and then the safety of the steel open caisson in the marine environment is guaranteed.
本申请公开一种钢沉井水下分仓封底施工方法，包括以下步骤：在钢沉井的外刃脚和内刃脚处设置活动挡板；钢沉井包括沿周向均匀设置的多个第一井筒和沿周向均匀设置的多个第二井筒，第一井筒有十六个，第二井筒有四个；外刃脚和内刃脚位于第一井筒的外壁底部和内壁底部；将钢沉井沉放至基坑处，将活动挡板下放至海底，使第一井筒的外壁底部和内壁底部之间密封；对四个第一井筒进行封底及刃脚注浆；四个第一井筒关于钢沉井的横桥向中心线和纵桥向中心线均对称设置；对边缆侧井筒进行封底及刃脚注浆；对主缆侧井筒进行封底及刃脚注浆；对第二井筒进行封底及刃脚注浆。该方法能保证钢沉井的水下封底质量，进而确保钢沉井在海洋环境中的安全。
