With the development of China's modernization, construction industry rose rapidly and has shown an unprecedented prosperity. And with the continuous innovation and progress of construction technology, new technologies, new materials, new technology and new equipment continue to emerge. Rotary drilling dry pore forming technology and pile forming technology is an important representative of construction technology innovation. In this paper, the concept, definition, advantages and working principle of the rotary drilling dry pore forming technology and pile forming technology are briefly described. Then the construction process and main points of the rotary drilling rig are described in detail. Finally, the quality control measures in construction stage are introduced. It is hoped that this process can be better applied in specific construction in the future.%随着我国现代化建设的发展,建筑行业迅速崛起,呈现出前所未有的繁荣景象.而且随着建筑技术的不断创新和进步,新技术、新材料、新工艺和新装备不断出现.旋挖钻干式成孔技术与成桩工艺就是其建筑技术革新的重要代表.本文首先对旋挖钻干式成孔技术与成桩工艺的相关概念、定义、优点及工作原理进行了简单的阐述,然后详细描述了旋挖钻机的施工工艺流程和要点,最后简要介绍施工阶段的质量控制措施,希望该工艺在今后建筑工程的具体施工中能够得到更好地应用.
