Existing line monolithic track bed transformation construction method
The invention relates to the technical field of urban rail transit, in particular to an existing line monolithic track bed transformation construction method which comprises the following steps: 1, construction preparation; 2, dismounting rail equipment; 3, checking the size deviation limit of the general monolithic track bed; 4, mounting a gantry crane running rail, and cutting a defense line; 5, punching and cutting by using a diamond barrel saw; 6, cutting by a diamond disk saw; 7, hydraulic jack pushing; eighthly, track bed blocks are hoisted on the track laying door; 9, rail car transportation; and tenthly, comprehensive quality inspection is conducted after the ballast bed is chiseled away. According to the method, the existing line monolithic track bed can be well transformed and constructed.
本发明涉及城市轨道交通技术领域，涉及一种既有线整体道床改造施工方法，其包括以下步骤：一、施工准备；二、轨道设备拆除；三、一般整体道床尺寸偏差限界检查；四、门吊走行轨安装、切割防线；五、金刚石筒锯打孔切割；六、金刚石圆盘锯切割；七、液压千斤顶顶推；八、铺轨门门吊装道床块；九、轨道车运输；十、道床凿除后全面质量检查。本发明能较佳地进行既有线整体道床改造施工。
