随着钻孔灌注桩在公路桥梁基础工程中广泛应用,质优、快速、环保、节能的钻孔施工技术得到不断发展。旋挖钻机施工工艺便是近几年在我国才热起来的一种较先进的桩基施工工艺,该施工工艺主要特点是施工效率高,环境污染小,适用于工期要求紧的工程项目,特别是市政工程。本文对桥梁桩基旋挖钻施工工艺及技术要点进行了探究,希望对同类型施工起到参考作用。 With the widespread application of cast-in-place bored piles in the foundation engineering of highway bridges and bridges, the drilling technology with high quality, fastness, environmental protection and energy saving has been continuously developed. Rotary drilling rig construction technology is only a few years in our country up to a more advanced pile foundation construction technology, the construction process is characterized by high construction efficiency, environmental pollution is small, suitable for tight schedule requirements of the project, in particular It is municipal engineering. This paper explores the construction technology and technical points of the bridge pile foundation rotary drilling and hopes to play a reference role for the same type of construction.
