7、ting, the way we take surveys solicited a views, combed, related to team building人工挖孔桩施工方案一、适用范围本施工方案适用于烟台市滨海公路海阳段丁字河口大桥人工挖孔桩施工。二、编制依据滨海公路海阳段丁字河口大桥招标文件项目专用本公路工程国内招标文件范本 滨海公路海阳段丁字河口大桥工程施工图设计滨海公路海阳段丁字河口大桥合同协议书公路桥涵施工技术规范（JTJ 0412000）公路全球定位系统（GPS）测量规范JTJ/T066-98公路工程质量检验评定标准（JTG F80/1-2004）国家一、二等水准测量规范（GB12898-91）全球定位系统（GPS）测量规范（GB/T18314-2001）其它国家标准、行业标准、技术条件及验收方法等三、工程概况丁字河口大桥桩基从1#84#墩，共计560根地下桩。其中根据招标图纸提供的地质资料及现场勘测，其中1#31#墩共31个墩位淤泥覆盖层为0.31.42 m不等；32#38#共7个墩位跨越鸭岛，表面为裸露的安山岩，我部针对现场实际情况，对1#38#墩共计176棵桩采

8、用人工挖孔桩。在不影响附近海产品养殖场换水的前提下，0#31#墩桥位两侧采用填土筑坝将施工区域围起清除淤泥形成无水作业区，38#墩筑岛围堰。卷扬机配三角架提升出渣，混凝土护壁，钢筋笼在钢筋加工厂下料，运输到施工现场后吊装入孔，混凝土由拌和站集中拌和，罐车运输。孔内无水时采用干灌、人工插入式振捣棒振捣。孔内有水时，采用水下灌注混凝土的方法施工。桩基计划从2009年5月1号至2009年11月30号结束，计划工期214天。四、施工前准备工作（1）在正式施工前，具备好以下工程资料。主要包括场地的工程地质资料；桩基施工图纸会审纪要；主要施工机械及其配套设备的技术性能资料；桩基的施工组织设计或施工方案以及桩基钢筋混凝土所用建材（水泥、砂石、钢筋）的质检报告。（2）在正式开工前，按照公司和项目部的相关规定，对技术人员和施工人员进行专项技术培训。按规定层层进行技术交底。由总工主持对施工技术人员和管理人员进行技术交底；由工程部会同施工队技术员对班组长进行技术交底；由班组长对所属人员进行技术交底。（3）试验室应在开工前完成水下35#混凝土配合比设计，并经过监理批准。五、测量定位采用全站仪按设计桩位进行精确

9、放样，保证桩位准确。并在桩位外设置纵、横向十字线控制桩，确保孔口平面位置与设计桩位偏差符合施工规范要求。放好轴线后，及时报告监理工程师验线，复核无误后方可施工。六、施工机具和人员安排挖孔井架8套，提土吊桶16个，潜水泵10个，上下吊笼8个，风镐4个，鼓风机和输风管3套。每个桩孔配3人总计24人，现场施工机械、水、电维修保养3人，现场施工技术员1人七、桩体施工1.开挖在进行人工挖孔时根据设计桩径及护壁厚度在地面上放出开挖线，然后向下挖深1m，浇筑混凝土井圈第一节护壁。井圈应高出地面20cm-30cm，并加厚。而后将桩位纵横中心线测放到井圈上，并测出孔口控制高程，以利于下部掘进的高程控制，控制第一井圈的中心线与设计轴线的偏差不得大于5cm。井圈高出地面还有利于防止地表水在施工过程中进入井内。安装卷扬机配三角架提升设备时，使吊桶的钢丝绳中心与桩孔轴线位置一致，为挖土时粗略控制中心线。挖孔过程中，将经常检查桩孔尺寸、平面位置和竖轴线倾斜情况，如有偏差应随时纠正。挖孔施工自上而下逐层进行，采用爆破施工方法开挖。人工挖孔桩施工过程中作业人数多，工序交叉多，为了保证入岩爆破安全、顺利进行应按以下程序进行组织管理：1.1施工管理（1）建立以项目部为指导的爆破作业指挥部，下设爆破总负责人、技术负责人、安全员及各班组长，各专业工种持证上岗。 （2）建立爆破器材集中收发制度，按工作量发料。多余的爆破材料在当班施工完成后，应及时上交给发放人员收回，做到集中发料、统一制作、统一收回、集中保管，严格登记手续，避免爆破器材流入社会。 （3）安排好作业时间、爆破时间并将爆破时间告示于周围居民。 （4）爆破总负责人负责施工组织、人员调配、生产安排，并对安全、生产负全责。 （5）技术负责人负责施工过程的技术工作，并监督安全和质量，全面指挥爆破工作的实施。 （6）安全员负责现场安全检查，布置检查爆破警戒。 （7）爆破员负责起爆工作。 1.2施工组织孔桩入岩爆破采用爆破专业作业法，即专业班组专职从事爆破工作，负责钻眼、清孔、
