The invention relates to the technical field of ocean engineering structures, and discloses a deck cabin-penetrating piece sealing structure and a construction method thereof.The deck cabin-penetrating piece sealing structure comprises a deck and a cabin-penetrating pipeline, the deck is provided with a cabin-penetrating opening, and the cabin-penetrating pipeline penetrates through the cabin-penetrating opening; the device further comprises two semi-ring plates, the two semi-ring plates are arranged on the outer side of the cabin penetrating pipeline in a sleeving mode, and the two semi-ring plates cover the cabin penetrating opening. The structure further comprises a plugging profile, the plugging profile is arranged on the side, away from the cabin penetrating pipeline, of the semi-ring plate, the plugging profile is of a circumferential closed structure arranged around the center of the cabin penetrating pipeline, a plugging space is defined by the plugging profile and the cabin penetrating pipeline, and the plugging space is filled with a grouting layer. The plugging space is filled with the grouting layer, the cabin penetrating opening is sealed, the airtight effect is achieved, meanwhile, offshore welding operation is avoided, and no damage is caused to existing anti-corrosion measures; the grouting layer is connected with the cabin penetrating pipeline and the blocking profile, the horizontal load of the cabin penetrating pipeline can be transmitted to the deck through the grouting layer, the good restraining effect on the cabin penetrating pipeline is achieved, reliability is high, and cost is low.
本发明涉及海洋工程结构技术领域,公开了一种甲板穿舱件密封结构及其施工方法,包括甲板和穿舱管道,甲板具有穿舱口,穿舱管道穿过穿舱口;还包括两个半环板,两个半环板套装在穿舱管道的外侧,两个半环板覆盖穿舱口;还包括封堵型材,封堵型材布置于半环板远离穿舱管道的一侧,并且封堵型材为绕穿舱管道的中心布置的周向封闭结构,封堵型材与穿舱管道之间围成封堵空间,封堵空间内填充有灌浆层。灌浆层填充在封堵空间内,对穿舱口进行密封,达到气密效果,同时避免了海上焊接作业,对现有的防腐措施没有任何损坏;灌浆层连接穿舱管道和封堵型材,穿舱管道的水平荷载可以经由灌浆层传递至甲板,对穿舱管道具有良好的约束作用,可靠性高且成本低。
