1、技术交底书工程名称中子铺隧道技术交底单位中铁十九局集团西成铁路客专线四川段XCZQ-1标第一项目部交底项目衬砌钢筋加工及安装(VC复合型衬砌)交底日期2013年8月20日一、技术要求钢筋施工,隧道衬砌受力钢筋接头宜设在受力较小处,受拉钢筋宜采用机械连接或焊接,其他钢筋可采用绑扎搭接,隧道衬砌拱部及边墙钢筋接头不得采用焊接。二、施工工艺及流程图1.施工工艺钢筋进场钢筋加工钢筋绑扎、连接成品钢筋验收成品钢筋保护1)钢筋加工[1]钢筋的调直、除锈钢筋的表面应洁净,使用前应将表面油渍、污迹、锈皮、鳞锈等清除干净。钢筋应平直,无局部弯折。钢筋在调直机上调直后,其表面不应有削弱钢
2、筋截面的痕迹。[2]钢筋切断和弯曲时注意长度准确,弯曲后平面上没有翘曲不平现象,钢筋弯曲点处不能有裂缝。钢筋加工成半成品后,按类别、直径、使用部位挂好标志牌并分类堆放整齐,使用时才吊、运送至使用部位。钢筋的弯制和末端的弯钩应符合设计及规范要求。[3]钢筋运输:钢筋在隧道内加工,加工好后由人工运至工作面,在运送及存放中要堆放整齐,轻抬轻放,防止变形。[4]加工后钢筋的允许偏差不得超过表中规定的数值:加工后钢筋的允许偏差表顺次名称允许偏差值(mm)1受力钢筋顺长度方向全长+102箍筋内径尺寸+53弯起钢筋的弯起位置20 接受
