7、架施工组织设计1工程施工模式该工程为车集线地销路立交桥、雪枫路立交桥的限高防护架施工，防护架使用43kg/m钢轨制作，由铁运处组织施工，具体分工为检修段负责按照图纸加工限高架，工务段负责限高架加工的监督和现场安装，供应科负责相关机具、材料的租用和购买。施工负责人分别为：检修段限高架制作负责人×××，分管领导×××。工务段施工负责人：×××；分管领导×××。主管科室管理人员：×××；负责领导×××。2工程施工方案2.1开工前交底及开工准备会：运输科组织工程相关单位现场交底，确定限高架设置的详细位置（明确到具体尺寸）、

8、高度。同时举行开工准备会，统一协调限高架制作与施工过程中的责任分工及注意事项，明确施工各工序检查和验收的步骤，确定开工时间。2.2钢结构制作：钢结构制作前，工务段试验5根钢轨按图纸的布置方法和跨度安装后，其下垂量达到多少，以根据桥梁高度具体确定限高架横梁高度。钢轨下垂量确定后，检修段资料.挑选具备使用条件的钢轨等各种材料，按照图纸要求进行钢结构的加工，共需制
