高速铁路膨胀土路基接触网基础旋挖钻施工技术

Construction Technology of Expansive Soil Roadbed Catenary Foundation by Rotary Digging Drill in High-speed Railway

针对高速铁路路基接触网基础施工过程中,经常存在因质量控制不到位而造成大量返工现象,通过对其各工序的卡控,合理选用机械以及自制的模具卡具等设备,增加了施工速度和精度,有效地控制了施工质量,为国内类似的路基接触网基础施工积累了经验。

For high-speed railway subgrade catenary foundation construction process, there is often a lot of rework due to quality control is not in place. Through each process control, reasonable choose of machinery and equipment such as home- made mould and fixture increased the construction speed and accuracy, effectively controlled the construction quality, which could accumulate experience for the domestic similar catenary foundation construction.
