U-shaped steel cofferdam for ship lock gate groove repair and ship lock gate groove repair method
The invention discloses a U-shaped steel cofferdam for ship lock gate groove repairing and a ship lock gate groove repairing method. The U-shaped steel cofferdam comprises a U-shaped steel cofferdam body. The U-shaped steel cofferdam main body is of a columnar structure with a semicircular, U-shaped, V-shaped or n-shaped cross section, and an opening with the width larger than that of a ship lock gate groove is formed in the side, facing the ship lock gate groove needing to be repaired, of the U-shaped steel cofferdam main body; columnar water stopping air bags are arranged between the side walls on the two sides of the opening and the river channel walls on the two sides of the ship lock gate groove, and water sealing is achieved through the corresponding water stopping air bags. The upper end, opposite to the hollow inner cavity, of the U-shaped steel cofferdam body is connected with the buoyancy tank device. When the ship lock gate groove is repaired, water is pumped into a water sealing space formed by the U-shaped steel cofferdam body and the river channel walls on the two sides of the ship lock gate groove to form a local dry ground space, and the ship lock gate groove is repaired in the local dry ground space. Local underwater dry construction can be achieved, the construction range is smaller, implementation is easy, operation is convenient and safe, and matched equipment is simple.
本发明公开了用于船闸门槽修复的U型钢围堰及船闸门槽修复方法，包括U型钢围堰主体；U型钢围堰主体为横截面呈半圆形、U字形、V字形或者冂字形的柱状结构，朝向需要修复的船闸门槽的一侧带有宽度大于船闸门槽的开口；开口两侧的侧壁与船闸门槽两侧的河道壁之间均设有柱形止水气囊，均通过相应的止水气囊实现水密封；U型钢围堰主体背向中空内腔的上端与浮箱装置连接。船闸门槽修复时，通过对U型钢围堰主体与船闸门槽两侧的河道壁形成的水密封空间抽水形成局部干地空间，在局部干地空间进行船闸门槽的修复。本发明能够实现局部水下干施工，施工范围更小，实施简易，操作方便安全配套设备简单。
