Construction process suitable for controlling slippage of railway high embankment abutment in soft soil area
The invention provides a construction process suitable for controlling slippage of a railway high embankment bridge abutment in a soft soil area, and relates to the technical field of railway bridge abutment treatment construction. A construction technology suitable for controlling slippage of a railway high embankment abutment in a soft soil area comprises the following steps that a hole is drilled in a roadbed on the abutment side, a buttress is poured, an auxiliary beam railway track is erected and constructed on the buttress, and the auxiliary beam is used for supporting the railway track; a working foundation pit is excavated in the railway track side located at the construction auxiliary beam; a main foundation pit is transversely excavated along the side wall, close to the railway track side, of the working foundation pit, and a box culvert is poured; and the box culvert is jacked into the main foundation pit through the jacking piece, after the box culvert is jacked to the preset position and elevation in the main foundation pit, the jacking piece is dismantled, and the roadbed is recovered. According to the method, the railway high-road bridge abutment which is seriously deformed and deviated due to settlement of the soft soil area and the like can be treated, and the problem of various bridge abutment diseases caused by settlement of the soft soil area can be avoided.
本发明提出了一种适用于控制软土地区铁路高路堤桥台滑移的施工工艺，涉及铁路桥台整治施工技术领域。一种适用于控制软土地区铁路高路堤桥台滑移的施工工艺，包括如下步骤：在桥台侧的路基上钻孔浇筑支墩，在支墩上架设施工便梁铁路轨道，利用便梁支撑铁路轨道；在位于施工便梁处的铁路轨道侧开挖工作基坑；沿靠近铁路轨道侧的上述工作基坑侧壁上横向开挖主要基坑，浇筑箱涵；利用顶动件将箱涵顶入到主要基坑内，箱涵顶进到达主要基坑内预定位置和标高后，拆除顶动件，恢复路基。本发明能够对软土地区沉降等原因造成变形和偏移严重的铁路高路桥台进行整治，且能避免继续出现由于软土地区沉降造成的各种桥台病害问题。
