近年来随着高层建筑的发展，桩基础已成为建筑的主要基础，特别是现场灌注桩基础，由于其在施工中噪声小，对周围的环境公害少，发展异常迅速。螺旋钻孔机是钻孔灌注桩施工机械中的位使者，随着高层建筑基础大、重、深化的趋势，也向大直径、大功率、超深度、多功能发展，可适 In recent years, with the development of high-rise buildings, the pile foundation has become the main foundation of the building, especially on-site cast-in-place pile foundation. Because of its small noise during construction, it has less harm to the surrounding environment and the development is extremely rapid. Auger drilling machine is a leader in construction machinery for bored cast-in-place piles. With the trend of large-scale, heavy-duty and deep-rooted high-rise building, it also develops to large-diameter, high-power, ultra-deep, and multi-functional.
