随着海上石油钻井、风力发电平台设施、深水港码头、跨海铁路、跨海大桥等国家大型工程项目的开工建设,在海上桩基施工中所采用的桩基础规格和承载力都远远超过陆上桩基础,钢管桩的直径和长度分别达到1.5 m和80 m以上,同时海上桩基施工中经常会出现地层坚硬和复杂的情况,这就对包括筒式柴油打桩锤在内的桩基施工设备的能级和操作性能提出了新的要求。
With the commencement of large-scale construction projects for offshore oil drilling, wind power platform facilities, deep-water port terminals, cross-sea railways, and cross-sea bridges, the pile foundation used in offshore pile construction has far more specifications and bearing capacity than On the land-based pile foundation, the diameter and length of the steel pipe piles reach 1.5 m and 80 m respectively. At the same time, the ground is often hard and complicated in the construction of pile foundations. This includes piles including tubular diesel hammers. New requirements are placed on the energy level and operating performance of the foundation construction equipment.
