旋挖法在铁路特大桥钻孔灌注桩施工中的运用

Application of Rotary Drilling in Cast-in-situ Pile Construction of Railway Megabridge

随着铁路客运专线施工的迅速发展,旋挖法施工钻孔灌注桩在铁路特大桥梁工程中得到广泛运用。该施工方法主要特点是施工效率高、质量好、环境污染少、噪音低,是一种较先进的钻孔桩施工方法。文章结合具体工程介绍旋挖法在铁路特大桥钻孔灌注桩施工中的运用。

In paco with railway construction,rotary drilling has found wide application in cast-in-situ pile construction of railway megabridge. Featuring high efficiency and high quality, environment-friendliness and low noise, rotary drilling is generally regarded as an advanced construction method for the bored pile. This article combines with a practical project to present the application of rotary drilling in the east-in-situ pile construction of railway megabridge.
