1、水泥砼道路面层施工方案砼路面的施工工艺流程如下：上基础验为合格?室内外试验完毕?安装模板？砼拌和？砼运输入仓?平板、插入式振动器振捣？初平？微振动梁振岛?二次找平?真空吸水?表面处理磨浆？推光？压痕？养护?锯缝？嵌缝等. 一、模板工程 1、安装 模板采用钢槽钢，高度同路面结构层同高，采用人工安装。砼路面两侧模板安装好坏，直接影响平整度，模板安装不牢（包括基础和加固支撑）在振岛时容易变样，特别是用振动梁振平时，两侧模板的高程是控制砼面形状的主要因素，两侧模板牢固，横坡合格率高、平整，纵向模板接头处要平顺，不变形,纵向平整度质量好，直顺度好。所以说模板安装质量是保证路面平整度第一因素。 2、模板的
2、拆除 模板拆除的时限应根据路面结构物的结构类型确定,须待到规范规定的砼强度值后方可拆模。 木模板拆除应使用专用工具,按各类模板结构支撑所确定的程序小心仔细地进行，避免对模板及砼面的损伤. 拆除后的模板应分别堆放,予以标识,并加以维护保养,以备再用. 二、钢筋工程 本工程钢筋主要是传力杆和角隅钢筋,量少，结构简单，加工方便.方便采用厂加工，运到现场人工安装。 Functions of the regulation in the presence of the cross overlapping， departments, units should promptly pass gas， timel

7、the completion of a comprehensive remediation tasks. 1、钢筋的进场及检验 钢筋应根据施工详图及进度计划要求组织钢筋进场。进场后堆放在钢筋堆放场，并予以标识。钢筋应有出厂合格证，进场后应按规范要求取样复检，合格后方可使用到本工程上。 2、钢筋加工 钢筋加工集中在工地钢筋加工厂内进行。 1)钢筋除锈、调直 钢筋下料加工前应先进行除锈、调直处理。清除钢筋表面的油渍、漆污和浮皮、铁锈等，并用钢筋调直机将弯曲的钢筋调直，钢筋除锈主要结合钢筋调直一起进行,在钢筋调直过程中除锈，必要时辅以机械、手工除锈。 2）钢筋配料 钢筋加工前仔细阅读施工详图和设计修
8、改通知，结合浇筑部位的分层分块，兼顾砼入仓方式，并根据钢筋运输、安装方法及所采用的接头形式，分解制定钢筋下料加工单. 3)钢筋切断 主要采用钢筋切断机切断钢筋。切断时将同规格钢筋按不同长度长短搭配，统筹排料,一般应先断长料，后断短料，减少短头，减少损耗。断料时在工作台上标出尺寸刻线并设置控制断料尺寸用的挡板，避免用短尺量长料. 4)钢筋弯曲成型 利用钢筋弯曲机按要求弯曲成型。 Functions of the regulation in the presence of the cross overlapping, departments， units should promptly pass

14、个工序.根据测量放样点在模板基础上划出钢筋位置线，籍以进行钢筋绑扎或连接。钢筋保护层用同标号的水泥砂浆预制垫块控制,垫块预埋铁丝与钢筋扎紧. 4）钢筋连接 钢筋现场连接主要采用手工电弧焊，施焊前，先进行钢筋定位,保证两钢筋的轴线在一条直线上。施焊时，引弧由一端开始，在搭接钢筋端头上收弧，弧坑应填满。其焊缝长度不小于搭接长度，搭接长度应符合规范规定，焊缝高度及宽度也应满足规范要求. 三、砼原材料的要求 Functions of the regulation in the presence of the cross overlapping, departments, units should pr
