1、b：成孔分四次进行：即第一遍和第二遍进行成孔，隔行隔点进行，第三遍和第四便对未成的孔也采用隔行隔点进行的方法进行；详细成孔遍数和要求见附图5-1。c：成孔时采用先外后内的原则进行。以形成对地基更有效的加固作用。d：桩机就位时一定要对准桩中心，就位后要调整工具桩的垂直度，成孔后孔的倾斜度不得大于1.5%H（H为桩长）；成孔后必须检查成孔效果（如深度；有无缩孔；塌落土700等现象）并做好施工记录，合格后立即回填夯实。e：成孔时位移偏差应小于50mm，成孔垂直度用吊线控制，应小于1.5H/100（H为桩长）。按总桩数的进行抽检。如遇到异常情况，则应和监理工程师及甲方代表及时联系，以便协商解决。 f：
2、成孔后要进行测量孔的深度，记录钻孔深度，实际测量深度及坍落土的厚度。3.8 、回填； a：依据试验条件书回填材料采用2:8灰土和素土进行。在试验篇素土区应回填素土，在试验篇灰土区应回填灰土。 b：2:8灰土中所用的消石灰进场时应有出厂合格证，复试报告及现场抽检合格后才能进行拌和使用。回填料在回填及夯扩前对2:8灰土要进行抽样击实实验，确定最优含水率及灰土的物理指标和化学性能，为施工控制提供可靠依据。 桩身采用素填土时土料颗粒不得大于15。回填时应先进行底夯，以夯实孔底的坍落土。回填时在填料（2:8灰土和素土）符合技术质量要求时方可进行，每次填料的数量应为三锨或一锨，夯锤夯击的次数分别为四击或和
3、一击，即三锨四锤。直至听到孔内发出“咚，咚”声为止。f：夯实机的锤重300kg以上，锤体直径小于400mm，但不能小于350mm的夯锤进行夯实，夯锤落距不小于2M。3.9、抽检：抽检由试桩和监理方同时进行，试桩期间用环刀法加杆臂对桩身的质量进行抽检并化验指标，随时抽查桩身的回填质量。3.10、记录，指现场试桩记录，试桩的本身目的是消除土壤湿陷性和提高地基的承载力，记录掌握在现场施工过程中的最基础的原始资料，包括桩径、桩长、含水量、干容重、回填料的数量、夯实机提升高度和夯击次数等，是调整参数和保证质量的必不可少的资料，依据规范和新的标准，由专业记录资料员进行，记录格式详见表1、表2。 施工记录表
