交底负责人&nbsp&nbsp&nbsp&nbsp参加人员&nbsp&nbsp&nbsp&nbsp
交底内容&nbsp污水管道施工&nbsp&nbsp&nbsp工作时间&nbsp2004。11。24–28&nbsp&nbsp&nbsp
工程量:&nbspD300波纹管安装220M、检查井7座&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
人员:&nbsp管道安装工5人、砌井泥工4人&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
材料:&nbspD300UPVC双壁波纹管、砖、砂、水泥&nbsp&nbsp&nbsp&nbsp&nbsp(详见材料清单)&nbsp&nbsp
机械:&nbsp0.5M3斗反铲、震动棒、小型夯实机械、砂浆搅拌机、翻斗车、泥工用具等&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
工作工序:&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp1、沟槽开挖。主要控制中线、高程、沟槽尺寸。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp中线控制:按原标示石灰线开挖,经常量距江峰围墙距离,管道中距江峰围墙2M。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp高程控制:由测量员每挖5M测一点控制,高挖低抬。出现超挖现象严禁用原土回填,应用级配砂砾回填。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp沟槽尺寸控制:每挖5M量沟槽底宽及放坡坡度,确保沟槽尺寸在设计范围内。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp2、管道垫层。本工程管道垫层由15CM砂组成。砂垫层应用水冲透,并用振动棒捣实,&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp以免管道安装后出现沉降现象。捣实后再次捡平达到设计标高。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp3、管道安装。管道安装时应注意管道中心距江峰围墙2M。安装要严把接口质量,防止接口渗水。安装完毕再次复检流水面标高使之符合设计要求。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp4、检查井砌筑。本工程检查井为收口式。井室内经1000MM、收口宽700MM、井深2.3-2.5M,井壁为24砖墙内粉。砌筑时严格按规程施工,砖砌前打水,砌时砂浆饱满均匀,井壁圆顺,砌后勾缝内粉。严禁出现通缝,砖块松动,掉粉现象。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp5、管道回填。回填材料应符合设计要求,严禁用腐植土、石块等回报填。回填时应两边对称填筑,以防推动管道。每回填30CM一层压实一层检测一层直到设计标高。&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
