- 笔者和本课题组同志,两次参加黄河穿越的管体外补口施工。通过对两次施工中外补口修补率的比较,肯定了先补口后试压的穿越工序,否定了另-穿越工序,并指出工序不合理是补口修补率高的主要原因。
The author and his colleagues have carrid out twice external weld coating for Yellow River crossing pipeline. Through comparing of 2 repairing ratio, the procedure of weld coating followed closely by the hydraulic test is affirmed. Another coating procedure is refused. The incorrect construction procedure is pointed out to be the main reason for the high repairing ratio.1988,1(1): 43-44 收稿日期：1987-7-13
