近几年来,旋挖钻机是钻孔灌注桩施工中一种较先进的施工方法,该施工方法主要特点是施工效率高,适用于工期要求紧的工程项目。本文主要介绍了旋挖钻机在某立交桥工程下部钻孔灌注桩基础工程中的应用,详细地阐述了旋挖钻机的施工工艺。
In recent years, rotary drilling rig is a more advanced construction method of bored pile construction. The main features of this construction method are high construction efficiency, which is suitable for engineering projects with tight construction schedule. This paper mainly introduces the application of rotary drilling rig in the foundation engineering of the lower part of bored pile in an overpass project, and expounds the construction technology of rotary drilling rig in detail.
