我国地域辽阔,地形及地貌相当复杂,在沿海一带尤为突出。随着我国基础建设的快速发展,钻孔灌注桩作为一种基础形式以其适应性强、成本适中,广泛应用于基建基础工程中,发挥了重要作用。现结合温州市城市防洪西向排洪工程温瞿公路桥工程实例,根据桩基础的特殊性和隐蔽性等特点,从施工准备阶段、施工阶段和工程验收阶段三阶段,详细阐述了灌注桩基础监理的特点及过程,以使灌注桩质量达到预期的质量控制目标。
China has a vast territory with a rather complicated topography and landform, especially in the coastal areas. With the rapid development of infrastructure in our country, bored piles have played an important role as a basic form because of their adaptability and moderate cost, which are widely used in infrastructural projects. In the light of the peculiarity and concealment of pile foundation, combining with the three stages of construction preparation phase, construction phase and project acceptance phase, this paper elaborates the basic conditions of construction supervision of cast-in-situ pile foundation supervision The characteristics and process to make the quality of the pile to achieve the expected quality control objectives.
