Urban subway short-term and long-term disassembly section monolithic track bed construction method
The invention discloses an urban subway short-term and long-term disassembly section monolithic track bed construction method. Relates to the technical field of subway construction methods. Comprising the following steps: measuring and setting a base map, scabbling and cleaning a base, disassembling points 1 and 2, scattering turnout materials, assembling and erecting a turnout, erecting a straight line section before the turnout, disassembling points 3, 4, 5, 6 and 7, scattering steel rails and base plates, erecting and positioning a long-term track, mounting a replacement base plate, remeasuring and fixing a nylon sleeve, disassembling the long-term track, erecting a recent steel rail and mounting the recent replacement base plate. The method comprises the steps of nylon sleeve retesting, steel bar binding and drainage strip and terminal welding, template and expansion joint mounting, track fine adjustment, acceptance acceptance by a supervision engineer, ballast bed concrete pouring, tool and template dismounting, trimming and maintenance, nylon sleeve protection cover mounting, local steel rail dismounting and base plate replacement, and recent iron base plate mounting and steel rail recovery. According to the construction method, the nylon positioning speed and success rate can be increased, operation is convenient, and the positioning precision is high.
本发明公开了一种城市地铁近远期拆解段整体道床施工方法。涉及地铁施工方法技术领域，包括：基标测设→基底凿毛、清理→拆解点1、2→散布道岔材料→道岔拼装、架设→岔前直线段架设→拆解点3、4、5、6、7→散布钢轨、垫板→远期轨道架设定位→安装替代垫板→尼龙套管复测、固定→拆除远期轨道→架设近期钢轨→近期替代垫板安装、尼龙套管复测→钢筋绑扎、排流条及端子焊接→安装模板、伸缩缝→轨道精调→报监理工程师验收合格→道床混凝土浇筑→工装、模板拆除、修整、养生→安装尼龙套管保护盖→拆除局部钢轨、替代垫板→安装近期铁垫板、恢复钢轨。通过本发明提供的施工方法能够提高尼龙定位速率及成功率，操作便捷、定位精度高。
