General概述This method statement is established to define construction method for the concrete wall of FJLNG phrase 1 Additional 3# and 4# Tanks project. 此方案适用于福建LNG一期新增3#和4#储罐工程混凝土墙体施工方案。2. Scope 范围Variations of sequence or method may evolve as the work progresses, which will maximize efficiency and use of available equipment and resources. A revised Method statement will be issued for variations in work practice. 施工顺序或方法会随工程进展而改动，以便最大化的提高资源使用效率。The tank wall is circular on plan, tank height of 50054mm, 1000mm thick tapering down to 550mm thick at a height of 6750mm. The inner radius of wall is 41000mm, the outer radius is 41550mm, and the thickness of standard wall is 550mm. The concrete C50 will be used for the wall, reinforced with high yield steel reinforcement on the faces of the wall and cryogenic reinforcement just be used on the inner face of lift 2. 罐体墙体为圆形, 罐高50054mm, 在高度6750mm范围内，罐厚从1000mm渐变到550mm. 墙体内径为41000mm,外径为41550mm,标准墙体厚度为550mm。墙体使用C50混凝土，墙体钢筋高屈服钢筋，第二层墙体内侧使用低温钢筋。Post Tensioning is applied to horizontal and vertical pre-stressing ducts built into the walls. 预应力适用于墙体的水平和竖直预应力管道。The description of tendon prestressing and duct grouting will be addressed in separated method statement. 预应力和孔道灌浆的描述参见单独的施工方案。During construction of the wall, welding joints and deformation of inserts control shall be performed by the mechanical subcontractor in accordance with the relevant specification, other work shall be carried out by civil contractor. The mechanical subcontractor shall use the access and platform set by civil subcontractor for welding of inserts. 在罐筒体施工过程中，预埋件焊接连接和变形控制措施工作由机械分包商按照相关规范执行，其余相关工作均由土建分包商完成。机械分包商进入筒体执行预埋件焊接时，可利用土建分包商设置的通道和操作平台。Construction will be 11 lifts of the following heights: 施工每层高度：Lift NoHeight (mm)Concrete Dosage(m³)1337579023375621338005874380058753800587638005877380058783800587938005871037755841111-1227553411-211004373.
