石家庄站提速道岔换铺施工技术

Construction Technique of Changing Speed-up Switches in Shijiazhuang Railway Station

对石家庄站北信号道岔区更换提速道岔施工难点进行分析,制定了切实可行的施工技术方案,采取了有效的施工技术措施。在常规的纵、横移道岔施工方法基础上,形成了在困难工程条件下换铺道岔较为成熟的施工工艺。换铺施工按计划如期开通,使石家庄站通过能力得到提高,运营条件得到明显改善,并积累了宝贵经验。

Construction technique of changing speed-up switches in Shijiazhuang railway station is summed up so that level of construction technique of changing switches will be promoted continuously. Difficult points which were confronted with while changing speed-up switches of the north switch section of Shjiazhuang railway station are analyzed. A feasible scheme is laid down and technical measurements of the construction are adopted effectively. Much more perfected construction technology of changing switches under difficult construction conditions is formed based on the common method of moving switches horizontally and longitudinally. The train passing capacity raised and the moving condition improved obviously since the changing construction is completed according to the project schdule.
