摘要
在既有铁路站场改造施工中,交叉渡线整组换铺施工由于施工场地受限、单次封锁要点时间长、对铁路运输影响较大、劳动力及机械设备一次投入多、施工组织困难、技术难度大、安全风险高等因素,一般很少被采用。但在特殊施工条件下,为满足铁路运输的需要,而必须采用整组换铺的施工方案。在贵州六盘水站站改施工中,在成都铁路局首次采用一次封锁要点整组换铺交叉渡线施工技术,并取得圆满成功。
In the transformation of existing railway station construction,cross-crossing the whole group of patchwork construction due to limited construction site,a single block a long time,a greater impact on rail transport,labor and machinery equipment,organizational difficulties,technical difficulty,high risk of security factors,generally rarely used. But in special construction conditions,in order to meet the needs of rail transport,and must use the entire group of paving the construction program. I units in Guizhou Liupanshui Station construction,in the Chengdu Railway Bureau for the first time to use a blockade points for the whole group of cross-crossing crossing construction technology,and a complete success.
