最大扰动力为91吨的BM2-5000振动打桩机,在日本被广泛用来拔出长20米和20米以上的钢桩。该机的振动频率可达1800次/分钟。该振动打桩机不仅能够拔出金属桩,而且还能够把直径不大于800毫米的钢管打入N≥50的承载土层中深2米和2米以上。该打桩机的偏心轮矩和振动频率可以根据桩
The BM2-5000 vibratory pile driver with a maximum perturbation force of 91 tons is widely used in Japan to pull out steel piles with a length of 20 meters and more than 20 meters. The machine’s vibration frequency can reach 1800 times/minute. The vibratory pile driver can not only pull out the metal pile, but also can drill a steel pipe with a diameter of no more than 800 mm into a bearing layer of N ≥ 50 in depth of 2 meters and more than 2 meters. The eccentric torque and vibration frequency of the pile driver can be based on the pile
