在水深20～200米的海底基床上建设建筑物(采油平台、人工岛机场、港口扩建等),需要采用新型船用钻探机具和原位测试仪器。由法国路易斯·莫纳尔德技术公司(Société Technique Louis Menard)改进的环形液压振动锤,非常适用于深度40～60米深层松软土质地基的连续取样作业,若增加振动锤的旋转功能.还可以对坚硬土壤进行取样作业。利用上述方法进行钻探、取 The construction of buildings (oil platforms, artificial island airports, port expansion, etc.) on submarine bed depths of 20 to 200 meters requires the use of new marine drilling rigs and in-situ test equipment. The ring-shaped hydraulic vibratory hammer, modified by Société Technique Louis Menard, is ideal for continuous sampling of deep, soft soil foundations with a depth of 40-60 m, if the vibratory hammer rotation is increased. Sampling hard soil. Use the above method for drilling, take
