Construction method for mechanized integral longitudinal movement cross crossover turnout of metro running line
The invention discloses a subway operation line mechanized integral longitudinal movement cross crossover turnout construction method. The method comprises the specific steps that S1, an existing turnout is measured and positioned; S2, the position of the turnout is adjusted, and the turnout is pre-assembled; S3, longitudinal movement rail bars are erected in a turnout area, and an uphill line is longitudinally moved in place for a long distance at a time; according to the subway operation line mechanized integral longitudinal movement cross crossover turnout construction method, excavator equipment which can be driven by wheels to advance on a rail is adopted as turnout longitudinal movement driving force, long-distance one-time longitudinal movement in place of an upslope line is achieved, and the problem that in the existing construction process, the construction efficiency is high on a ground two-layer side type station, and the construction cost is low is solved. The problems that generally used cross crossover turnouts are wooden turnout sleepers, along with long-time operation of subway stations, existing wooden sleeper turnouts cannot meet operation requirements, the site position is narrow in the construction process, lateral assembly cannot be carried out, turnout transverse movement cannot be carried out, and uphill lines cannot longitudinally move in place at a time in a long distance are solved.
本发明公开了一种地铁运营线机械化整体纵移交叉渡线道岔施工方法，具体步骤包括S1：对既有的道岔进行测量和定位，S2：对道岔进行调整位置并预拼装，S3：道岔区域搭设纵向移动轨条，上坡线路长距离一次纵移到位；该地铁运营线机械化整体纵移交叉渡线道岔施工方法，采用能够在轨道上使用轮子驱动前进的挖机设备作为道岔纵移推动力，实现上坡线路长距离一次性纵移到位，解决了现有的施工过程中在地面二层侧式车站，通常使用的交叉渡线道岔为木岔道枕，随着地铁车站的长时间运营，现有的木枕岔道满足不了运营的需求，而且施工时场地的位置比较狭小，无法侧位拼装实施道岔横移的问题，上坡线路长距离不能够一次性纵向移动到位的问题。
