The invention provides a vertical jacking construction method for a water outlet in a shield tunnel under seabed hard rock geology, which comprises the following steps: determining a target construction position, and carrying out vertical hard rock obstacle removal construction at the target construction position; shield tunnel construction at the target construction position is completed; vertical jacking construction of the water outlet is carried out in the tunnel at the target construction position; wherein the jacking construction path is consistent with the obstacle clearing construction path of the target construction position; and after the drainage pipe reaches the designed jacking position, the jacking closing plate is opened, and construction is completed. According to the vertical jacking construction method for the drainage outlet in the shield tunnel under the seabed hard rock geology, the hard rock obstacle removing construction process is added, the problem that a drainage pipe cannot be jacked under the seabed hard rock geology is solved, the vertical jacking construction method is suitable for vertical jacking construction of various stratum drainage outlets, and the adaptability of the construction method is higher.
本发明提供一种海底硬岩地质下盾构隧道中排水口垂直顶升施工方法,包括:确定目标施工位置,在目标施工位置进行垂直硬岩清障施工;完成目标施工位置盾构隧道施工;在目标施工位置由隧道内进行排水口垂直顶升施工;其中,顶升施工的路径与目标施工位置的清障施工路径一致;待排水管到达设计顶升位置后,打开顶升闷板完成施工。本发明海底硬岩地质下盾构隧道中排水口垂直顶升施工方法,加入了硬岩清障施工流程,解决了海底硬岩地质排水管无法顶升的问题,适用于对各种地层排水口进行垂直顶升的施工,施工方法适应性更强。
