The invention relates to a method for manufacturing an overweight segment on a segmented site, which comprises the following steps of: 1, screening out straight segments which are constructed in the same period in a larger site according to a segment construction plan, and arranging the screened straight segments to a smaller site for construction; 2, a jig frame is arranged in a small site, and fixed jig frames are arranged on the two sides of a movable jig frame; 3, straight segmented construction is conducted on the jig frame; 4, after the straight section is constructed, the connection between the straight section and the jig frame is removed, the movable jig frame is cut off, and the flat car is moved to the position before the movable jig frame is cut off; and 5, the straight sections are lifted up through a flat car till the straight sections are separated from the fixed jig frame, the straight sections are moved to a dock area through the flat car, and the straight sections are hoisted to a special portal frame to be placed through a gantry crane. On one hand, the problem that a ship building site is insufficient can be relieved, and the problem that hoisting cannot be carried out due to overweight segments after segment building is completed is solved;
本发明涉及一种在分段场地上制造超重分段的方法,该方法包括以下步骤:步骤1、根据分段建造计划,筛选出较大场地内同期建造的平直分段,将筛选到的平直分段安排至较小场地进行建造;步骤2、在较小场地布置胎架,活动胎架的两侧设置固定胎架;步骤3、在胎架上进行平直分段建造;步骤4、平直分段建造完成后,拆除平直分段与胎架之间的连接,割除活动胎架,将平板车移动至活动胎架割除前的位置;步骤5、通过平板车将平直分段托起直至平直分段脱离固定胎架,通过平板车将平直分段移运至船坞区域,通过龙门吊将平直分段吊运至专用门架上搁置。本发明一方面可以缓解船舶建造场地紧张的问题,解决分段建造完成后由于分段超重无法吊装的问题。
