Development and Application of New Technology of Offshore Vibroflotation Crushed-Rock Pile under Low Headroom Conditions
Based on the sea reclamation project of Hong Kong Boundary Crossing Facilities(HKBCF)of Hong Kong-Zhuhai-Macao Bridge,to meet the constraints of clearance and environmental protection and etc.,a special technology of bottom feed vibro stone column combined with telescopic pipe equipment is firstly proposed,which meets the requirements for the construction depth,quality,the constraints of low headroom and environmental protection,and brings more benefit in construction.The above construction technology and method are described comprehensively from such aspects as headroom constraint,technical requirements of design,telescopic pipe equipment&technology and construction result analysis.The research will provide a reference for the sea reclamation projects involving in offshore base improvement.
