The invention discloses a pneumatic horizontal dock gate untwisting maintenance method which comprises the following steps: S1, a preparation stage: a tidal bulkhead and a seaport seal hole form a closed left cabin and a closed right cabin, an air pipeline and a plurality of groups of bollards are connected to a B surface of a dock gate, two groups of floating cranes are prepared, and temporary winches are mounted at the head parts of the floating cranes; s2, degumming: utilizing two groups of floating cranes to hook the dock gate and take cables, enabling the floating cranes to abut against the dock gate in a T-shaped mode, injecting water into the dry dock to enable the dock gate to lie flat, and lifting the dock gate through the cooperation of the two groups of floating cranes to realize untwisting and floating; and S3, dock gate docking maintenance: two tugs are adopted to pull the front and back cables of the dock gate end to end, and the dock gate is dragged to be docked for maintenance. A sling and an air pipeline are installed at one end of the dock gate, the other end of the dock gate is connected with a tug, dock gate reinstallation is basically a twist-off reverse operation process, and the dock gate reinstallation comprises the steps of tidal bulkhead/seaport hole sealing, air pipeline connection and bollard installation on the B face of the dock gate. The safety of the dock gate in the dismantling and reinstalling process can be guaranteed.
本发明公开了一种气动卧倒式坞门脱绞维修方法,包括以下步骤:S1:准备阶段:潮汐舱壁、通海口封孔形成封闭左右舱室,其中在坞门的B面连接空气管路和多组缆桩,准备两组浮吊,其首部安装临时绞车;S2:脱胶:利用两组浮吊将坞门挂钩并带缆,且浮吊与坞门采用丁靠形式,干坞内注水将坞门躺平,通过两组浮吊配合将坞门提起实现脱绞上浮;S3:坞门进坞维修:采用两条拖轮分首尾将坞门前后带缆,将坞门拖拉进坞维修。S4:坞门回装:坞门的一端安装吊索以及空气管路,另一端连接拖轮,坞门回装基本是脱绞逆向操作过程,包括潮汐舱壁/通海口封孔、联接空气管路、在坞门B面安装缆桩的步骤。本发明能够保证坞门在拆除及回装过程中安全性。
