Construction method for reconstructing existing line CRTSI type double-block ballastless track sleeper
The invention belongs to the technical field of ballastless track rectification, and particularly relates to a construction method for reconstruction of existing line CRTSI type double-block ballastless track sleepers. Comprising the following steps that S1, the adjustment amount needed by a sleeper is determined; s2, installing steel bearing beams to replace sleepers to temporarily support the steel rails; s3, fasteners on original sleepers are dismantled, the steel rails are shifted to the fasteners of the steel sleeper beams, and the steel rails are buckled and pressed; s4, the sleeper and surrounding concrete are chiseled away, and original sleeper lower-layer truss ribs and longitudinal and transverse steel bars of the roadbed slab are reserved; s5, reinforcing steel bars, sleeves and a sleeper mold are installed, the sleeper mold is finely adjusted, and sleeper pouring is conducted; before the skylight point is finished, the mold is dismantled and maintained; s6, after the strength of the sleeper meets the requirement, the steel sleeper beam is dismantled, and the steel rail is transferred to a new sleeper fastener and buckled and pressed; s7, reconstruction construction of the section of sleeper is completed; compared with a traditional total chiseling and reconstruction mode, the method has the advantages that the chiseling range is small, lines can operate normally, equipment used for construction is few and small, engineering waste is little, and construction efficiency is high.
本发明属于无砟轨道纠偏技术领域，具体涉及一种既有线CRTSⅠ型双块式无砟轨道轨枕重构的施工方法；包括以下步骤：S1：确定轨枕需要的调整量；S2：安装钢垫梁代替轨枕临时支撑钢轨；S3：拆除原轨枕上的扣件，将钢轨拨移至钢垫梁的扣件上并扣压钢轨；S4：凿除轨枕及周围混凝土，保留原有轨枕下层桁架筋，以及道床板纵、横向钢筋；S5：安装加强钢筋、套管及轨枕模具，精调轨枕模具，进行轨枕浇筑；天窗点结束前完成模具拆除并养护；S6：轨枕强度达到要求后拆除钢垫梁，将钢轨转至新构轨枕扣件并扣压钢轨；S7：完成该段轨枕重构施做；与传统的全部凿除重构方式相比，凿除范围小、线路可正常运营、施工使用设备少且小、工程浪费少、施工效率高。
