Therefore, the following rules must be observed: 1.1 起吊时构件至少应捆扎两处，捆扎处须有衬垫物，并捆扎在有筋板等加强节点处，一 般应尽可能捆扎在构件的两端，不宜捆扎在非节点部位或构件的外伸部。 The components must be lifted with being enlaced at least two points where there must be gaskets, and they should be enlaced at the stiffener nodes of stiffener, normally, the components should be enlaced at the two ends, it is improper to enlace them at places without nodes or extensional part. 1.2 搬运时应将构件搁置在载重汽车或平板车上，禁止直接在地面上放滚拖移。 The components should be placed on trucks or flatcars while transported. It is forbidden to roll or pull them directly on the ground. 1.3 存放时应安置平稳，用枕木垫实放平，枕木应对称放置，地面也必须选择结实平整完 好处，以防日久下沉以致构件变形。 They should be stored on stationary crossties, and the crossties should be placed in symmetry. The ground must be solid, smooth and intact, thus avoiding deforming of the components due to ground falling as time passes. 1.4 零(部)件如需露天存放的，应遮盖好，对存放日期长或露天存放的件安装前应检查锈 蚀情况，清除污渍，必要时重新涂油组装，使各转动部分灵活，并检查各联接部分的牢固 性。存放期间应定期保养，注意防潮、防锈和通风。 If some parts and components need be stored outdoor, they should be well covered. Those that will be stored for a long time or outdoor should be inspected their rust situations before installation and derusting, and repainted and reassembled if necessary 越南沿海一期火力发电厂项目 DQ1200/2500.40 悬臂式斗轮堆取料机安装技术条件及调试、试验规程 DUYEN HAI 1 THERMAL POWER PLANT PROJECT- DQ1200/250040 Boom Bucket Wheel Stacker cum Reclaimer Technical Conditions of Installation it is strictly prohibited to assemble forcibly. 1.3 为减少高空作业量，应尽量在地面上连接。 Connection should be done on the ground in order to reduce work high above the ground. 越南沿海一期火力发电厂项目 DQ1200/2500.40 悬臂式斗轮堆取料机安装技术条件及调试、试验规程 DUYEN HAI 1 THERMAL POWER PLANT PROJECT- DQ1200/250040 Boom Bucket Wheel Stacker cum Reclaimer Technical Conditions of Installation the undercut of the welding seam is not greater than 1mm, if the plate thickness is more than 10mm; and the continuous length of the undercut will not more than 100mm. The total length of the bilateral undercut shall not exceed 10% of the total length of the welding seam. d.焊缝应呈圆滑过渡至母材的几何形状，焊缝转角处应饱满。 Weld should be smooth transition to base metal geometry in shape, the corner of 越南沿海一期火力发电厂项目 DQ1200/2500.40 悬臂式斗轮堆取料机安装技术条件及调试、试验规程 DUYEN HAI 1 THERMAL POWER PLANT PROJECT- DQ1200/250040 Boom Bucket Wheel Stacker cum Reclaimer Technical Conditions of Installation torque error percentage of wrench for correction is not more than 3%. 1.5.1.1.5 大六角头高强度螺栓的拧紧应分为初拧、 终拧。 对于大型节点应分为初拧、 复拧、 终拧。初拧扭矩为施工扭矩的 50%左右，复拧扭矩等于初拧扭矩。初拧或复拧后高强度螺 栓应用颜色在螺母上涂上标记，然后按施工扭矩值进行终拧。终拧后的高强度螺栓应用另 越南沿海一期火力发电厂项目 DQ1200/2500.40 悬臂式斗轮堆取料机安装技术条件及调试、试验规程 DUYEN HAI 1 THERMAL POWER PLANT PROJECT- DQ1200/250040 Boom Bucket Wheel Stacker cum Reclaimer Technical Conditions of Installation 越南沿海一期火力发电厂项目 DQ1200/2500.40 悬臂式斗轮堆取料机安装技术条件及调试、试验规程 DUYEN HAI 1 THERMAL POWER PLANT PROJECT- DQ1200/250040 Boom Bucket Wheel Stacker cum Reclaimer Technical Conditions of Installation The smallest section of ground wire which used bare copper wire shall not be less than 4mm2; if it is insulation copper wire, its smallest section shall not be less than 2.5mm2 ( within 1kV). 第四节 涂装第四节 涂装 Section 4: Coating 4.1 本机涂装喷涂严格按有关工艺要求进行。制造厂在设备出厂前油漆已涂完厂内应涂的 漆种和涂层。运输和安装中碰掉的漆膜现场补漆（高强度螺栓连接面不喷漆） ，层数不能 减少。最后一道面漆现场安装、调试完毕后由施工单位喷涂。现场面漆材料随设备自带。 Painting for this machine must carry out according to relevant technological requirements strictly.
