以钻孔桩作为公铁路桥梁、码头、高层建筑工程的基础是一种有效的方法,已在世界上广泛应用。大桥局桥梁机械制造厂在深入分析了国内外钻机产品技术性能的基础上,结合我国目前国情、研究设计制造了BDM系列大口径钻机、该系列钻机是适合于我国大多数地层,又能在严酷的施工条件下使用,便于流动的工程钻机。该系列钻机共有4种型号,适用于岩石强度100MPa左右的岩层及一般表土层钻孔桩施工,最大钻孔直径
The use of bored piles as the foundation of public railway bridges, piers, and high-rise building projects is an effective method that has been widely used in the world. The Bridge Bureau Bridge Machinery Manufacturing Plant, in-depth analysis of the technical performance of domestic and foreign drilling rig products, combined with China’s current national conditions, research design and manufacture of the BDM series of large diameter drilling rig, this series of drilling rig is suitable for most of China’s strata, but also in the harsh The use of the construction conditions, the flow of the engineering rig. This series of drilling rigs has a total of 4 models, suitable for construction of rock layers with a rock strength of about 100 MPa and borehole piles in general surface soil.
