Existing railway shoulder heightening and widening treatment method
The invention discloses an existing railway shoulder heightening and widening treatment method which comprises the following steps: step 1, drilling holes in the ditch wall and the ditch bottom of a drainage ditch on the outer side of a shoulder along an existing railway, arranging anchor rods in a driving manner, and exposing partial length of the anchor rods; 2, fine aggregate concrete is adopted for carrying out heightening and widening pouring on the existing railway shoulder, and the poured fine aggregate concrete covers the anchor rod which is driven and exposed; 3, a drainage hole is buried in the fine aggregate concrete, and heightening pouring continues to be conducted; and 4, widening the existing drainage ditch to form a new drainage ditch. When the method provided by the invention is used for heightening and widening the road shoulder, excavation operation does not need to be performed on the existing railway road shoulder, so that the influence of collapse of railway ballasts and interference on existing line driving is avoided, a new heightening and widening structure and an existing railway roadbed can form a whole, and the problems that the existing railway road shoulder sinks and the width of the road shoulder is insufficient can be effectively solved.
本发明公开了一种既有铁路路肩加高加宽处理方法，包括如下步骤：步骤1：沿既有铁路在路肩外侧排水沟的沟壁和沟底钻孔，打设锚杆，所述锚杆的部分长度外露；步骤2：采用细石混凝土对既有铁路路肩进行加高、加宽浇筑，使浇筑的所述细石混凝土覆盖已打设外露的所述锚杆；步骤3：在所述细石混凝土内埋设泄水孔，并继续进行加高浇筑；步骤4：对既有所述排水沟进行拓宽处理，形成新排水沟。采用本发明提供的方法加高、加宽路肩，无需对既有铁路路肩进行开挖作业，避免了道砟的溜塌和对既有线行车干扰的影响，能使新的加高、加宽结构与既有铁路路基形成一个整体，可有效解决既有铁路路肩下沉、路肩宽度不足的问题。
