Preset correcting and positioning method for cast-in-place ballastless track bed sleeper in curve section
The invention particularly relates to a preset correcting and positioning method for a cast-in-place ballastless track bed sleeper in a curve section, and solves the problems of large adjustment workload, low working efficiency, high cost and measurement and control data distortion when an existing construction method for replacing a curve with a broken line is used for a working condition with asmall curve radius. The invention discloses a preset correcting and positioning method for a cast-in-place ballastless track bed sleeper in a curve section. The method comprises the following steps of: 1) compiling a sleeper installation error table and a track panel adjustment operation correction table; 2) marking a sleeper mounting position on the tool rail; (3) assembling the track panel by using the special-shaped track gauge check blocks; 4) using a fine-tuning trolley to adjust the position of the tool rail; 5) correcting the measurement data; and 6) pouring the concrete of the track bed. According to the invention, the purposes of sleeper presetting and measurement and control data correction are achieved, the construction efficiency is effectively improved, and the construction cost is reduced; meanwhile, the problem of measurement and control data distortion is solved, and the construction quality is effectively improved.
本发明具体是曲线地段现浇无砟道床轨枕的预置修正定位方法，解决了现有以折线替代曲线的施工方法在用于曲线半径较小的工况时存在调整工作量大、工效低、成本高且测控数据失真的问题。一种曲线地段现浇无砟道床轨枕的预置修正定位方法，所述方法包括以下步骤：1）编制轨枕安装误差表与轨排调整作业修正表；2）在工具轨上标记轨枕安装位置；3）利用异形轨距挡块组装轨排；4）利用精调小车对工具轨位置进行调整；5）对测量数据进行修正；6）浇筑道床混凝土。本发明实现了轨枕预置与测控数据修正的目的，有效提高了施工效率，降低了施工成本，同时解决了测控数据失真的问题，有效提高了施工质量。
