Railway non-stop roadbed replacement and filling construction method
The invention discloses a railway non-stop roadbed replacement and filling construction method. The method comprises the following steps that S1, construction preparation is conducted; s2, monitoring equipment on an original closed layer is dismounted, existing signal equipment is changed and moved, and a contact network foundation is protected; s3, construction is conducted on a foundation bed below the track, the space between the lines and the outer side of the track through a step-by-step warehouse-jumping method, and an operation groove is excavated to a waterproof layer; s4, after track falling is completed, the track is finely adjusted, the guide height of the contact net is adjusted, and then the operation groove is poured, filled and caulked; s5, re-installing the monitoring equipment and the signal equipment on the original closed layer; and S6, the transportation channel on the outer side of the road shoulder is dismantled, and the roadbed slope is sealed and subjected to water prevention and drainage. Under the condition that operation of the high-speed rail is not affected, roadbed replacement and filling construction can be conducted, economic losses caused by shutdown of the high-speed rail are avoided, the construction cost can be saved to the maximum extent, operation of the high-speed rail can be maintained conveniently, stability of the excavated rail can be kept, and therefore the construction efficiency is greatly improved.
本发明公开了一种铁路不停运路基换填施工方法，包括以下步骤：S1、施工准备；S2、拆除原封闭层上的监测设备，改移既有的信号设备，保护接触网基础；S3、对轨道下基床、以及线间和轨道外侧采用分步跳仓法施工，开挖作业槽至防水层；S4、待落道完成后，精调轨道，并调整接触网导高，然后对作业槽浇筑填充并嵌缝；S5、重新安装原封闭层上的监测设备和信号设备；S6、拆除路肩外侧的运输通道，对路基边坡进行封闭及防排水。本发明能在不影响高铁运营情况下，进行路基换填施工，避免了高速铁路停运带来的经济损失，能最大限度的节约施工成本，便于维护高铁运营，能保持开挖后轨道的稳定，从而大大地提高施工效率。
