“后预制梁板、预制场、预应力筋”案例分析与答案解析题 案例背景材料： 某高速公路K20十300m处有一座主跨为2m×30m预应力混凝土空心板，采用预制吊装，后施工。该桥左侧有一大块空地，拟作为预制场。主要施工要点如下： 1．制作台座。在预制场地上放出台座大样，平整压实后现浇20cm厚C20混凝土，台座上铺钢板底模； 2．外模采用已经使用过的同尺寸板梁的定型钢模板，内模采用外包镀锌薄钢板。所有模板试拼合格。 3．在台座上制作钢筋骨架，并按要求系好钢筋保护层垫块，在钢筋骨架制作过程中将波纹管按设计坐标固定在钢筋骨架上。 4．安设锚垫块后，先安装端模板，再安装已涂刷脱模剂的外侧钢模，并按要求设置压浆和排气，报监理工程师检查同意后，吊运混凝土入模。先浇底板混凝土，再安装内模，后浇腹板和顶板，整个过程均用插人式振捣棒振动密实。混凝土浇筑完成后，按要求养生。 5．预应力。将钢绞线穿人波纹管道内（钢绞线下料长度考虑工作长度），进行作业。千斤顶共2台。在另一工地上校验后才使用一个月，可直接进行控制作业。使用一台千斤顶单端，另一台备用。时千斤顶的作用线必须与预应力轴线重合；时采用伸长量控制、应力作为校核； 6．拆除设备，将道冲洗干净，即压注水泥浆。整个压浆过程符合设计规定。 问题： 1、该方案中台座制作有何问题？ 2、空心板梁混凝土浇筑过程中有何问题？ 3、预应力筋过程中有何错误之处？ 4、道压浆操作是否正确？并加以说明。
