The invention relates to a method for installing a ship bottom drain plug, which comprises the following steps of: marking a datum line on an outer plate of a cabin section according to the cabin section construction datum line, performing a tightness test after the cabin section construction is finished, then determining the center of an opening by taking the datum line as a datum, marking an opening contour line by taking the center of the opening as a circle center, and finally performing a sealing test on the opening contour line. Tapping is conducted along the opening contour line, then a base plate is installed, welding tightness inspection is conducted on the base plate after welding of the base plate is completed, and finally coating operation of cabin sections is conducted. According to the method, the tapping installation of the discharge plug is carried out in the segmented construction stage, the problems that the tapping positioning difficulty in the block stage is large, and tapping is easy to be carried out to the bulkhead position or the adjacent cabin are solved, and the tapping difficulty is reduced; coating is carried out after trepanning, so that damage to paint is reduced; the cabin tightness test is carried out in the sectioning stage, and the welding seam tightness test is carried out after the seat plate is installed, so that the sectioning construction completeness is improved.

    本发明涉及一种船底放泄塞的安装方法,按照舱室分段建造基准线在舱室分段的外板上划出基准线,舱室分段建造完成后进行密性试验,然后以基准线为基准确定开孔的中心,以开孔的中心为圆心划出开孔轮廓线,沿开口轮廓线进行开孔后安装座板,座板焊接完成后进行座板焊接密性检验,最后进行舱室分段的涂装作业。本发明在分段建造阶段进行放泄塞的开孔安装,避免总段阶段开孔定位难度大、容易开孔至舱壁位置或者邻近舱室的问题,降低了开孔的难度;并且在开孔后进行涂装,减少对油漆的破坏;在分段阶段进行舱室的密性检验,在座板安装完成后进行焊缝密性试验,提升了分段建造的完整性。
