The ground marking must ensure the appearance size in the theoretical data range, at the same time, the inspection line is needed to ensure the outer plate alignment and the groove dimension.2.必須進行基準線施工（147/150mmM.K）,對于合攏時的肋檢線等須敲上相關的洋沖。2. The reference line must be constructed (147/150mmM.K),

7、and the closure frame checking line must knock the checking points.3.劃線結束后由施工隊提出報驗，精度管理人員對其尺寸進行復核使其在理論允許的誤差范圍內。3. The construction team should put forward the marking inspection, and the accuracy control department review the size to ensure the error within the allowable range theory.4.劃線驗收合格簽字后進入下一

9、, frame, brackets and so on. Some side panels of the block will also composed by a box, compartment. The side plates are setted in the jig. Although the structure is different, the assembly methods are basically the same.1. 旁板的裝配流程（以124-SS1A為例）1. The assembly procedure of the side plate (in the case

10、 of the 124-SS1A)1.1先裝配前要根據圖紙對結構的理論線進行確認1.1before the assembly we must confirm the theory line of the structure according to the drawings .1.2外板劃線結束后，并對主要結構位置進行水平確認，水平調整到位后進行剛性支撐固定。1.2 After scribing, to confirm the level of the main structure, then rigid support fixed in place.1.3水平調整結束后進行上內部結構，先上縱

11、向的T拍并進行定位焊。然后進行肋板定位，肋板定位的時候必須注意與上口企口線對齊，所有肋位必須保證上口端面平齊。斜板端面和開口必須保證到位。1.3 After level adjustment, we can welded the internal structure. the longitudinal T bar is firstly located and welded. Then the frame is located, you must pay attention to ensure the upper end face is flush. The inclined plate sur

12、face and the opening must be secured in place.Ground ling management1.4肋骨裝配，從上口企口位置開始定位一直到下口，保證企口位置在同一條直線上，而且保證肋骨與外板緊密貼合。1.4 Rib assembly, you should locate from the upper rabbet to the lower rabbet. We must ensure the rabbet in the same line and also ensure the ribs and the outer plate closely.1.5裝

13、配完成后進行水平和尺寸自檢，并報檢B精度，B精度合格后開始關鍵位置焊接。1.5 After assembly, the construction team should take in the horizontal and size self-inspection, and apply “B” accuracy inspection. After passing the “B” accuracy inspection, the key structures can be welded.1.6焊接完成后拆除支撐固定，自檢完成報檢C精度，C精度合格后進行火工作業，最終合格后方可脫胎。1.6 Aft

14、er welding, the supporting and fixing can be removed. After self-inspection, the construction team should apply “C” accuracy inspection, then the explosive operation is allowed. Finally, the block can be removed from the jig.五.曲型分段的控制辦法（以124分段為例）The fifth chapter: The control methods of typical bloc
