1. 工程概况
我单位于二0一0年十二月至二0一一年四月施工了STX海洋重工三重管旋喷施工项目。该工程位于大连STX海洋重工船厂内，在厂内建一个亚洲最大的龙门吊，荷载900吨，其中#6G/C龙门吊轨道加长一对，DM轴轨道梁长为62.23m，#7g/c龙门吊轨道一对，A’M‘轴轨道梁长分别为908.09m及912.59m，#7G/C龙门吊轨道基础南侧一段，坐落在海边护岸上，基础采用1.5m灌注柱，灌浆及旋喷桩。旋喷桩设计采用三重管旋喷注浆。旋喷桩所在场地长72m，宽15m，设计旋喷钻孔440个，工程量9300m，1.5m灌注桩18个，旋喷桩在它之下：钻孔布置及剖面如图1图2（图例旋喷孔兼灌浆孔和升浆孔旋喷孔）。
