All parti

26、cipants must install personnel technical tests before installation and construction, to familiarize them with the construction program, to ensure that the program correctly, smooth and safe implementation.1）施工现场要求1) the requirements of the construction site为保证设备施工的正常进行，安装队进场前，所有现场厂房、土建基础等基本设施必须施工完毕，

27、主要设备已基本到达现场，工程能够无间断的进行。现场吊装位置要足够，路面情况符合吊装需要。建设单位除保证水电气三通，尚需提供预装、储存等必要场地。因为工程施工时间紧张，为保证工作时间紧凑，安装队需要连续加班工作，建设单位应提供人员进出、环境设施等方便。In order to ensure the normal construction equipment, the installation team approach, all on-site plant, construction and other basic infrastructure construction must be compl

28、eted, the main equipment has been basically arrived at the scene, the project can be carried out without interruption. Lifting site location should be enough, the road, subject to the lifting needs. In addition to water, electricity and construction units to ensure that the three-way, still need to

29、provide the necessary space pre-installed storage.Because the construction time constraints, to ensure that working time is compact, continuous installation team needs to work overtime, the construction unit shall provide personnel access, environmental facilities and so convenient.2）基础检查清理2) the ba

30、sis of cleaning up检查所有设备和场地、基础设施基本尺寸和施工质量，重点检查贮槽基础标高、表面水平度及定位尺寸并清理干净。基础查对验收应分两步走，责任要明确。设备基础的尺寸和位置的质量要求应符合相关的土建标准。第一步建设单位与土建施工单位以施工图为准，对各个单体设备基础进行验收。第二步建设单位与安装单位以设备供货单位的基础图为准，逐个基础进行仔细查对，不符合要求坚决返修。基础验收资料应齐全，应有施工设计单位设计的基础设计蓝图、砼试块试验报告、基础竣工移交单，包括标高误差、中心偏差、坐标位置等。水平标高基准点，以设计图为准。Check all equipment and venu

31、es, infrastructure, basic dimensions and construction quality, focus on examination of the tank foundation level, size and positioning surface levelness and clean. Based check acceptance should take two steps, the responsibility must be clear. Quality requirements of equipment based on the size and

32、location should be consistent with the relevant civil standards. The first step in the construction unit and construction unit to the civil construction plans prevail, for each device based monomer acceptance. The second step in the construction unit and install unit foundation drawing equipment sup

33、ply units prevail, scrutinized one by one basis, and resolutely not meet the requirements for repair. Basic acceptance documents should be complete, should be the basis of the blueprint construction design unit design, concrete test block test report, the completion of the transfer basis, which incl

34、ude elevation error, center deviation, coordinate location. Level elevation reference point to design prevail.3）设备开箱清点3) inventory of equipment out of the box按照设备安装次序对现场设备进行开箱清点，检查质量，核实数量，并作好记录，将存在问题和缺件情况提交建设单位和设备供货单位。开箱清点的依据是以设备供货单位编制的发货清单和装箱清单为准，清点时要求三方人员参加：设备供货单位、建设单位、施工单位。开箱前应确认箱号和箱数，并作好记录。应检查箱体

35、和包装情况，箱体是否完好，若已损坏暂不开箱，查明原因后处理。三方确认箱体完好后才能开箱检查。检查时，按装箱清单的序号逐件进行清点，数量、实物与随机图纸核对；检查装箱资料是否齐全，材料的材质证明书考核项目是否齐全，并加以确认。制造内槽的主要受压元件（筒体、底板、顶盖、开口补强板等）上应有材质标记，和检验员钢印。材料外观质量应符合对应的材料标准和有关制造标准。清点过程中要认真做好记录，如设备名称、型号和规格等项目，以及设备缺件，三方签字认可，做到责任明确，竣工资料符合要求。数量清点过程中，同时也应进行质量检查，检查中应根据设备、机器、仪表等各自的要求填写主要另部件质量检查记录，检查内容一般有：（1

36、）外型尺寸是否符合图纸、工艺文件或竣工图尺寸要求。（2）有无损伤处，特别是运输过程中损伤情况。（3）对金属件查看有无锈蚀、裂纹等，焊接处是否符合图纸要求和有关标准规范要求（是否预弯、加工坡口等）；板材表面是否经过表面处理、油漆等。（4）对阀门等查看是否符合设计图纸要求。（5）对标准件（法兰、螺栓、螺母、管件等）检查是否与标准号相符，抽查每批中的一到两件，检查是否与标准件尺寸相符。清点的设备、机器、标准件和预制另部件等，要编号或按供货产品代号分类堆放，对于小件和仪电控制元件要入库保管。设备清点中发现的缺陷、缺件等应及时办理签证手续，通知有关单位处理。设备及材料的清点检查签证记录资料应及时收入施工

37、档案。In accordance with the installation sequence of field devices out of the box inventory, quality checks, verify the quantity, and make records, there will be problems and lack of parts and equipment submitted by the construction unit suppliers.Unpacking the inventory is based on the packing list a

38、nd shipping list prepared by the equipment suppliers of the subject requires personnel to participate in the tripartite when inventory: equipment supply units, construction units, construction units.It should confirm the box number and box number in front of the box, and make records. Check the box

39、and packing, the box is in good condition, If it is damaged temporarily out of the box, identify the reason for treatment. Three confirmed after checking out of the box to the cabinet intact. Inspection, piece by piece, by serial number packing list will be counted, the number of physical random dra

Equipment and materials inventory check visa information should be promptly recorded revenues construction archives.4.2 储罐预制及预拼接4.2 Tank prefabricated and pre

47、splicing 1）清理施工现场，合理利用施工场地，布置要紧凑合理，焊机就近放置，最好放在焊接组装平台和贮槽基础间适当位置，避免焊接电缆太长，或者摆放在干燥通风的房间里，若没有合适的房间，放在露天时则需设置防雨防尘棚；阀门、管件、安装用工具等小东西放在就近干燥通风的贮藏室，还需准备一间小屋，作为暗室。2）槽体组装场地应平整、面积比较大。贮槽四周应有5米宽的场地供堆放筒体。本贮槽采用倒装顺序安装。1) clean up the construction site, the rational use of the construction site, arranged to be reasona

48、bly compact welder nearest place, preferably on the basis of a storage tank and welding assembly platform between the appropriate location, to avoid welding cable is too long, or placed in dry and ventilated room where, if there is no suitable room, you need to set the time on the open-air shed rain

49、 and dust; valves, fittings, installation tools and other small things on the nearest dry and ventilated storage compartment, need to prepare a hut as a darkroom.2) tank assembly site should be flat, relatively large area. Sump four weeks should be 5 meters wide space for stacking the barrel. The su

50、mp flip the order of installation.4.3 低温储槽的施工程序：4.3 cryogenic storage tank construction program:储槽施工基本程序如下，部分施工程序可能根据最终图纸进行调整。The basic procedure is as follows chart, part of the construction program may be adjusted according to the final drawings.外筒底板- -内筒顶盖-外筒筒体-外筒顶盖-同时安装筒体-绝热层-内筒底板-附属部件The outer

51、cylinder bottom - - Inside the barrel cover - in cylinder barrel - the outer cylinder cap - installed cylinder - Heat insulation spacer layer - Inner cylinder bottom plate - Accessory parts4.3.1 储罐壁板（包括抗压圈）预制4.3.1 tank wall (including compression ring) Prefabricated内外罐壁板采用总包方提供的板料，检查直角度、直线度，如发现直角度和直

52、线度偏差，采用切割方法修正。注：在切割过程中如果发现材料有夹层、材料表面有严重锈蚀等缺陷，应停止使用该材料，并及时向总包方书面报告。Inner and outer tank wall using the total package provided by sheet check straight angle, straightness, straight angle and found straightness deviation, using the cutting method amendment. NOTE: If you find that in the process of cutt

53、ing the sandwich material, the surface of serious corrosion and other defects, should stop using the material, and timely written report to the total package.贮槽外槽由底板、筒体、顶盖、平台梯子栏杆等部分组成。底板由许多钢板拼焊而成，它与筒体间由双面角焊缝连接，此处残余应力较大，焊接下来后产生的收缩力较大，加上底板上拼缝多而长，焊接残余应力复杂，为了使底板焊后变形情况符合图纸要求，即局部凹凸变形不超过变形长度的2%，只允许中心凸起，且最大

54、不超过图纸允许值，为减少组焊后的校平工作量，必须采用适当的装配焊接顺序，正确的顺序是使筒体与底板间的环向角焊缝的收缩不牵连到底板的主体，使之能比较自由的收缩，根据这个原则，将底板分为两个部分，一部分是和筒体直接连接的边缘板，第二部分是不与筒体连接的中间板。组装前先清理基础表面灰尘、杂物等，可用水冲洗干净，然后让其风干。底板示意图及焊缝情况见图纸。The tank outside the tank comprises a bottom plate, cylinder cover, ladder platform railings and other parts. The bottom plate

55、 is made of many steel plates welded together, and its cylinder body by a double fillet weld connection, the residual stress is larger and the shrinkage force generated after welding down greatly, and floor seam and long welding. The residual stress is complex, in order to make the plate after weldi

56、ng deformation meet the requirements of the drawings, namely the local convex deformation is not more than 2% of the length of deformation, only allow the center bulge, and the maximum does not exceed the allowable value for drawing, reducing the workload of leveling group after welding, must use appropriate assembly welding sequence, the correct order is to make the cylinder body and the bottom plate between the circumferential fillet weld shrinkage not implicated in the end plate main body, so as to compare the free shrinkage,
