旋挖钻机施工工艺和经济可行性探讨

Probe into the Construction Technique of the Rotary Excavating Drill and Its Economic Feasibility

通过旋挖钻机在北京市某国家重点工程施工过程中的应用,重点对其施工工艺和经济可行性进行了论述,并通过与传统的回旋钻机的对照分析,指出了旋挖钻机在保障工期、节约成本、满足环保要求等方面的优势,是以后桩基施工的发展方向。

Through the application of the rotary excavating drill in the construction of a certain national major engineering in Beijing City, this paper discusses on its construction technique and its economic feasibility, and through the comparative analysis on the traditional rotating drill, points out that the rotary excavating drill construction technique is the developing direction of the foundation construction because of its superiorities in the construction period, construction cost, and environmental protection, etc.
