Manhole construction method for guide pipe leg of guide pipe frame with depth of 300 meters
The invention relates to the technical field of deepwater ocean equipment, in particular to a manhole construction method for a guide pipe leg of a 300-meter deep guide pipe frame, which is characterized in that a manhole is creatively formed in the side surface of a pipe section before the final assembly of the guide pipe leg, and a worker can enter the pipe section from the manhole after the final assembly of the guide pipe leg, so that the time for the worker to take place in a construction position is greatly shortened, and the construction efficiency is improved. The working efficiency is improved, and if an emergency occurs in the pipe section, the working personnel can timely evacuate, so that the personal safety of the working personnel is guaranteed; in addition, after final assembly of the conduit leg is finished, the originally cut manhole cover plate is used for welding and sealing the manhole, and the position, where the manhole is originally formed, of the conduit leg meets the requirements of structural load, residual stress, delayed crack size, safety margin and the like through a specific welding process. It is guaranteed that the jacket can stably operate under severe environmental factors such as storm attack, seawater erosion and deep sea high pressure in deep water.
本发明涉及深水海洋装备技术领域，具体涉及300米深导管架导管腿的人孔施工工法，本发明在导管腿总装前，开创性的在管段侧面开设人孔，导管腿总装后工作人员能够从人孔进入到管段内，大大缩短了工作人员就位施工位置的时间，提高工作效率，并且若在管段内出现突发情况时，工作人员也能及时地撤离，保障工作人员的人身安全；并且本发明在导管腿总装结束后用原切割下的人孔盖板焊接封盖人孔，通过特定的焊接工艺使导管腿上原先开人孔的位置满足结构载荷、残余应力、延迟裂纹尺寸和安全裕度等要求，保证导管架能够在深水下需经受风浪侵袭、海水侵蚀、深海高压等恶劣的环境因素稳定运行。
