The invention provides a full-pressure type LPG transport ship cargo tank integrity hoisting construction process. The full-pressure type LPG transport ship cargo tank integrity hoisting construction process comprises the following steps that the installation position of laminated wood and the installation position of a falling tool are marked on a cargo tank; a temporary saddle is arranged in an inner field, and the cargo tank is placed on the temporary saddle through a gantry crane; step bridge sections are welded to the top of the cargo tank, watertight partition plates are welded to the cargo tank below step bridges, and falling tools are welded to the two sides of the cargo tank; the laminated wood is installed at the bottom of the cargo tank, and epoxy is poured; hoisting the cargo tank again by using the gantry crane, arranging a layer of adjusting cork wood on a temporary saddle panel, and controlling the gantry crane to enable the cargo tank to stably fall on the temporary saddle; performing water pressure test on the cargo tank; coating operation is conducted on the cargo tank; the cargo tanks are preliminarily located; the gap between the laminated wood and the saddle panel is filled with epoxy pouring, and hoisting is finished; the folding ends of the subsections of the step bridge are connected through steel plates. According to the construction process, the construction difficulty is reduced, the construction period is shortened, and potential safety hazards in construction are eliminated.

    本发明提供一种全压式LPG运输船货罐完整性吊装建造工艺,包括以下步骤:在货罐上将层压木的安装位置和落位工装的安装位置进行标记;在内场布置临时鞍座,用龙门吊将货罐放在临时鞍座上;在货罐顶部焊接步桥分段,步桥下方的货罐上焊接水密隔板,货罐两侧焊接落位工装;将层压木安装在货罐底部,并且浇筑环氧;用龙门吊再次将货罐吊起,在临时鞍座面板上布置一层调整软木,控制龙门吊将货罐平稳落在临时鞍座上;对货罐进行水压测试;对货罐进行涂装作业;货罐进行初步落位;对层压木与鞍座面板之间的间隙进行环氧浇筑填充,结束吊装;步桥分段之间的合拢端用钢板进行连接。本建造工艺降低了施工难度,缩短了施工周期,消除了施工中的安全隐患。
