31、厚地段，由于地基经常浸水湿软，含水量大，施工前做好抽水清淤、清淤至水田、水塘、鱼塘底硬土层，为防止因淤泥可能出现的路基盆形沉降、失稳等问题按设计要求作好回填整平。找平层填筑土质的粒径一般不得大于5cm的渗水性砂性土，坡度不得小于3%，并碾压密实（形成排水坡)，?遇有田埂或陡坎时将其削成不陡于20的斜坡面。 3、复测清表后横断面 软基处治范围的表土、淤泥清理完成后,及时报请测量组复测清表后的横断面,横断面的桩号应与清表前的桩号一致。复测结果应报监理工程师签认。 4、填筑泥质岩层 清表完成并经复测横断面后，在碎石桩施工前先填筑一层泥质岩并进行场地平整，其质量必须满足上述要求. 5、桩位放样 场地平

32、整完成，经监理检查验收合格后。严格按照设计图的桩位进行放样，并采用小木桩标识和编号、绘制桩位图。放样时先放先序施工的桩位，桩位偏差不得大于3cm，放样结果报监理验收签认。桩位按照设计要求进行布置。 6、桩机就位 将沉管机就位，套管对准桩孔。定位时要保证桩锤中心与地面定End of 2021 I County file made poor 。.。 。.。 Million, some time ago， we follow provincial and municipal requirements for filing state card poor looking back” activitie

38、批加入，不宜一次加料过量，原则上要“少吃多餐”,保证试桩标定的装料量，上提振动成桩过程中，护壁送料管不得缺料.采用反复压、拔管法施工时，套管每上提100cm后应下压50cm,同时根据制桩试验成果严格控制电流和振冲器在固定深度位置的留振时间，同时复核填料数量，使其和设计用量的差值必须符合设计规定，3以1m桩长所需碎石量0.27m作为控制参素数。未达到规定的密实电流时应继续加料，继续下压、振实，严格防止“断桩和“缩颈桩的发生。碎石桩形成后,必须大于中密状态(N63。5？10）. 施工前应按规定做成桩试验,试桩不得少于77m范围,纵向、横向各5根。试桩中应做好记录冲孔、制桩时间和深度、压入碎石量及电

39、流的变化等参数。经验证设计参数和施工控制的有关参数后作为碎石桩施工的控制指标。操作中严格控制电压稳定，一般为（380？20)V。严格控制加料振密过程中的密实电流,密实电流的规定值应根据现场制桩试验定出，宜为额定电流的90，左右;严禁在超过额定电流的情况下作业。振冲器在固定深度位置的留振时间宜为1020s。 End of 2021 I County file made poor 。.。 。 Million， some time ago， we follow provincial and municipal requirements for filing state card poor ”look
