摘要
结合南宁吴圩国际机场T3航站区及配套设施建设工程-航站楼工程二标段项目,对强岩溶发育区桩基设计施工进行研究.桩位勘察采用一桩一孔+管波探测法,替代传统的一桩多孔.在桩位中心勘察钻孔进行管波探测,可快速探明桩位范围的岩溶、软弱夹层及裂隙带的发育和分布情况.较传统一桩多孔的桩位勘察方式,节省勘察成本,加快建设工期.桩基施工采用干成孔施工工艺,针对串孔、塌孔、溶洞等不良地质采取针对性的处理方案,以控制施工质量.
Abstract
Combined with the T3 terminal area of Nanning Wuwei International Airport and supporting facilities construction project-terminal building project,the design and construction of pile foundation in the strong karst development area are studied.One pile hole+pipe wave detection method is used to replace the traditional multiple pile hole.The pipe wave detection in the borehole of the pile center can quickly explore the development and distribution of karst,weak interlayer and fissure zone in the pile range.Compared with the traditional pile hole,the survey cost is saved and the construction period is accelerated.The construction of pile foundation adopts the dry hole construction technology,and the targeted treatment scheme is adopted for the bad geology such as cross hole,collapse hole and karst cave to control the construction quality.
