41、、夯实水泥土桩复合地基施工1、施工准备采用32.5MPa矿渣硅酸盐水泥,质量符合国家标准,进场水泥由建设方见证取样,进行复验,质量合格,水泥:土=1:6(体积比)拌合,含水量手攥成团,落地开花。2、主要机具短螺旋钻机,电动夯实机3、作业条件3.1 施工作业范围的地表、地下和空中障碍物应清理或改移完毕,对不能改移的障碍物必须进行标示,并有保护措施。3.2 对施工场区进行清理平整,对不利于施工机械行走的松软地面进行碾压或夯实处理,以保证各种设备行走的安全和平稳。作到路通、电通。 3.3场地地面标高应高于设计桩顶标高0.2m以上,避免对成桩质量产生影响。4、施工工艺4.1测放桩位:根据设计桩位布置图

42、,测放桩位,桩位用钢钎打眼灌白灰做标识。4.2成孔:采用短螺旋钻机成孔,且满足设计要求。桩 径:350mm,偏差允许20mm;桩 位:偏移不超过87.5mm;成孔深度:桩端进入持力层(层粉土)不小于500mm,桩长偏差允许值-0,+500mm。成孔垂直度:偏差不大于1.5%。4.3筛土:灰土桩用土原则上使用成孔取出的好土。其土料应过2025mm筛或粉碎,防止大颗粒土块和杂物与灰拌合。4.4拌合与回填:过筛土与水泥拌合按1:6配制,一般人工拌合时,拌合次数不少于3遍。拌好的水泥土料需在两小时内填入孔内,以确保桩体强度。4.5夯实:为了保证桩体密实度和强度,采用机械夯机夯实,夯机就位时要严格控制使

43、夯锤中心与孔中心对准。采用2填料1夯击的施工方法,每次投料厚度约50mm。填料前先夯实孔底,然后分层回填拌合料并夯实。4.6施工工艺流程图如下:桩位测放成孔夯实孔底(2击)填料(2填)夯实(1击)封顶夯实筛土水泥土料拌合5、水泥土桩自检在施工过程中,采用轻便触探检测桩体夯实质量,随机抽样量为总桩数的2%。30cm击数大于40击。检查压实系数是否满足要求。6、成品保护6.1施工过程中应注意保护好现场的轴线和高程点。6.2成孔后应及时填料夯实成桩,填料前孔口须加盖板保护,并作好标志,防止行人、车辆行走。6.3施工顺序的选择应考虑对成品的保护,避免机械行走时碾压成品桩或桩孔,桩顶应留200mm厚保护
