摘要
为使普通大口径钻孔机正常施工，加了钢筒支撑，钢梁架构，机动与手动两用移车系统等辅助设施，并配合反循环洗井工艺，克服了地层复杂以及大量水底建筑垃圾、渔业生产遗弃物等困难。
Steel pipe support,steel girder,and metor-driving and manual operation dual-purposed morable maching system are used for the purpose of enabling large-aperture drilling rig to operate normally.Combined with reverse circulation flushing techniques,the remaking of large bore brilling rig for the float offshore drilling platform overcomes the diffculties of complex strata,submarine building rubbish and abandoned fishery articles in the bore priming pile construction of float platform.
