Construction method for conflict position of standard gauge railway and existing narrow gauge railway
The invention provides a construction method for the conflict position of a standard gauge railway and an existing narrow gauge railway. The construction method comprises the following steps that firstly, the track position is determined; 2) determining the elevation of the track; (3) standard rail railway roadbed construction; (4) standard rail railway ballast construction is carried out; (5) cross turnout subsection side position pre-laying is carried out at the conflict position of the standard gauge railway and the narrow gauge railway; (6) the narrow gauge railway line is dismantled, and a ballast bed is replaced and filled; (7) the pre-laid cross turnout is pushed to be in place; (8) the cross turnout is arranged, and after transverse movement of the cross turnout is completed, the line is primarily maintained so that the line can meet the boarding condition; and 9) finely adjusting the cross turnout and the connecting line steel rail. According to the method, the crossing turnout is arranged at the intersection of the newly-built standard rail railway and the existing narrow-gauge railway, so that the standard rail train and the narrow-gauge train can pass on respective rails and do not interfere with each other, and the problem of coexistence of railways built under two different standards is solved. The method has the advantages of low construction difficulty, low construction cost and high construction efficiency.
本发明提供一种标准轨铁路与既有窄轨铁路冲突处施工工法，包括以下步骤：步骤1）确定轨道位置；步骤2）确定轨道高程；步骤3）标准轨铁路路基施工；步骤4）标准轨铁路道砟施工；骤5）标准轨铁路与窄轨铁路冲突处交叉道岔分段侧位预铺设；步骤6）窄轨铁路线路拆除、道床换填；步骤7）预铺设完成的交叉道岔推进落位；步骤8）交叉道岔整道，交叉道岔横移完毕，对线路进行初养使其具备上车条件；步骤9）交叉道岔及连接线钢轨精调。本发明在新建标轨铁路与既有窄轨铁路相交处设置交叉道岔，使标轨火车和窄轨火车均可在各自轨道上通行互不干扰的工法，解决了两个不同标准下修建的铁路实现了共存的问题。具有施工难度低，施工成本低和施工效率高的优点。
