旋挖钻孔灌注桩施工技术是一种绿色施工工艺,旋挖钻机用短螺旋钻头和岩石筒钻挖松岩土并将提钻带到孔外,它具有钻进效率高、成孔质量好、污染小和自动化水平高的特点,在沿海复杂地质层的地区有较高的发展前景。本文将简述旋挖桩技术的原理,结合具体案例分析旋挖技术的工作流程、优点和缺点、应用情况和前景,对沿海地区旋挖桩技术的实施有一定的指导意义。
Rotary drilling bored pile construction technology is a green construction technology, rotary drilling rig with a short spiral drill bit and rock tube drilling excavation of rock and soil will be raised to the hole, it has the drilling efficiency, pore quality, The characteristics of small pollution and high automation level have a higher development prospect in the areas with complicated geological formations along the coast. This article will briefly describe the principle of rotary pile technology, combined with the specific case analysis of the work flow, advantages and disadvantages, the application and prospects of rotary drilling technology, the implementation of the rotary pile technology in the coastal area is of guiding significance.
