摘要
钢板桩护岸施工中,部分钢板桩主桩长>20m,为非常规超长钢板桩,打入地层为吹填珊瑚砂/礁灰岩时,打设难度较大。施工中综合使用挖掘机和起重机,通过振动锤进行多方位、多方式打桩试验,形成行之有效的珊瑚砂/礁灰岩坚硬地质条件下钢板桩振动沉桩施工技术。
During the steel sheet pile revetment construction,the constructed sheet piles are partially unconventionally more than 20 m that are driven into the reclamation hard coral sand/reef limestone with such a difficulty. Through the trial tests of excavator vibration method and crawler crane vibration method during construction,a workable and efficiency construction technology of sheet piling vibration driving at hard coral sand/reef limestone stratum is formed.
