旋挖泥浆护壁钻孔灌注桩施工技术

来源:十一选五_十一选五云南|网站首页

十一选五 1)shigongyuanli

主要是其成孔工艺与其它桩基不同,旋挖钻机的钻进工艺旋挖钻机采用静态泥浆护壁钻斗取土的工艺,是一种无冲洗介质循环的钻进方法,钻进时为保护孔壁稳定,孔内要注满优质泥浆,旋挖钻机工作时能原地作整体回转运动。旋挖钻机钻孔取土时,依靠钻杆和钻头自重切入土层,斜向斗齿在钻斗回转时切下土块向斗内推进而完成钻取土;遇硬土时,自重力不足以使斗齿切入土层,此时可通过加压油缸对钻杆加压,强行将斗齿切入土中,完成钻孔取土。钻斗内装满土后,由起重机提升钻杆及钻斗至地面,拉动钻斗上的开关即打开底门,钻斗内的土依靠自重作用自动排出。钻杆向下放关好斗门,
