Only by vigorously promoting three, we can attract more projects, more enterprises, for the town to build a solid foundation, to provide an inexhaustible power. Four is the implementation of three is the top priority of every town, street, Department. Three as the Countys first project, core work, each town must seize, grasp the reality of the street. At present, the County also fully take into account the practical difficulties exist in villages and towns, determined by the wages of第二章 排水工程施工监理实施细则第一节 工程特征、设计要求和编制依据1.1工程特征及设计要求1、本项目东西接线立交互通工程，采用雨污分流制，其中雨水由管道收集排入附近水渠，雨水管道的管位及高程和其他管线位置见施工图设计，污水设计待定。由于本项目立交工程全线填方，雨水通过雨水口收集排到道路外侧的盖板涵，在排至盖板涵外侧的800mm1200mm800mm1500mm雨水管后汇入附近水体。全线管径为300mm1200mm800mm1800mm。注：内数据为西接线立交工程用。2、管道结构和施工要求（1） 施工图所注管道标高均为管内底标高。（2） 钢筋混凝土管基础（垫层）采用C20混凝土。（3） 管道交叉时，中间应土夹石夯实。当管道混凝土基础尺寸满足不了（D500时，H1000mm15两井之间2用水准仪测量3相邻管内底错口D1000mm3两井之间3用尺量D1000mm3两井之间3用尺量注：D1000mm15每座1用水准仪测量注：表中D为管径。7、雨水井（1） 监理工作要点： 根据设计文件规定，检测井位、支管的定位、定向和高程。 检查所使用的井框、井铁箅子的出厂质量，是否符合要求。 随时抽查水泥砂浆、砖的抗压强度。 检测雨水井的内外砌筑尺寸及支管接口质量等。 检验井周、支管回填压实质量 检测井口高程、与路边线吻合情况，并对外观进行检查，发现缺陷部分应指示承包人修整。（2） 质量标准、检测频率与方法 雨水井内抹面必须平整，不得起壳裂缝。 井内严禁有垃圾等杂物。 井框、井箅必须完整无损，安装应平整。 允许偏差，见表2-6表2-6序号项 目允许偏差（mm）检验频率检验方法范围点数1井框与井壁吻合必须符合CJJ3-90附录三的规定每台班1组按CJJ3-90附录三的规定2井口高程10mm20m1用水准仪测量3井位与路边线吻合不小于设计规定20m2用尺量，宽厚各计1点4井内尺寸20mm20m2用尺量，每侧计1点8、闭水试验（1）监理工作要点： 审查承包人申报进行闭水试验的方案、措施，准备工作是否满足进行闭水试验的要求。 检查试管段堵口封闭质量，管道、井身有无因明显缺陷而形成的漏水或严重渗水的部位。发现有上述缺陷时，应通知采取有效措施进行修复，直到满足验收要求为止。 监测闭水试验全过程，检查是否按规定程序进行闭水试验，参与测定30min渗水水量，评定渗水量是否质量检验评定标准。（2）质量标准、检测频率与方法设计要求闭水的排水管道必须作闭水试验；闭水试验应在管道回填前进行；闭水试验必须在管道灌满水后经24h后再进行；闭水试验的水位，应为试验段上游管道内顶以上2m。如上游管内顶至检查井的高度小于2m时，闭水试验水位可至井口为止；对渗水量的测定时间不少于30min。（2）规定值或允许偏差见表2-7。表2-7序号项 目规定值或 允许偏差检验频率检验方法范围点数1其他管道D1500mm每3个井段抽验1段1注：表中D为管径。 9、沟槽及基坑回填（1） 监理工作要点： 根据沟槽不同部位的回填要求，审查承包人的标准击实试验，并与试验监理工程师所作的平行试验进行比较，确定最佳干密度。 监测现场回填砂的最佳含水量与砂压实度是否符合沟槽部位回填砂的设计要求。 检测分层回填虚铺厚度、碾压机具、碾压遍数、碾压步骤是否符合施工组织设计，分段搭接是否符合要求。（2） 质量标准、检测频率与方法 回填时，槽内应无积水。 不得回填淤泥、腐植土、冻土及有机物质。 在管顶上500mm内，不得回填大于100mm的石块、砖块等杂物； 沟槽不同部位的回填砂的压实度标准，见表2-8。表2-8序号项 目压实度（%）检验频率检验方法范围点数1胸腔部分90两井之间每层一组（3点）用环刀法检验2管顶以上50mm内85两井之间每层一组（3点）用环刀法检验3管顶以上50mm以上当年不修路或农田85两井之间每层一组（3点）用环刀法检验图2-1 排水管渠工程质量监理工作流程施工组织设计、施工计划施工工艺工人、技术人员数量机械品种、数量材料到场情况及试验报告分包单位质资排水管道开工申请承包人监理工程师审核不同意同意 开工 承包人根据合同条款、规范要求，自检合格，并附有资料不合格合格返工不合格合格检验结果现场抽样检查专业监理工程师汇总、检查排水管渠工程中各工序质量验收报验单并将其编号填入中间交工证书监理工程师填写中间交工证书承包人排水管渠工程完成填写各工序质量验收单专业监理工程师监理工程师审批签认中间交工证书监理工程师试验室检查试验工程师现场检查现场监理工程师填写各工序质量验收报验单承包人运营保障部分行政管理、物业管理、党群工作和IT信息四个职能方向。行政管理下设综合主管、综合管理（内勤）、后勤保障、固定资产管理resource-processing enterprises the proportion of production value of industrial output reached . .%.
