随着建筑工程行业的快速发展,砼钻孔灌注桩施工技术被广泛应用。然而受砼钻孔灌注桩施工环境的限制,在成桩过程中出现了一些问题。本文通过向莆铁路FJ-1A标管段内光明1#特大桥、光明2#大桥、龙池溪特大桥、大水垄中桥等桥梁桩基础的施工中的实践经验,浅谈混凝土灌注桩的施工工艺和成桩质量的关系、常见施工质量问题及防治措施。 With the rapid development of construction industry, the construction technology of concrete bored pile is widely used. However, due to the restriction of the construction environment of concrete bored pile, some problems have appeared in the pile-forming process. In this paper, through the practical experience of the construction of bridge pile foundations such as Guangming No. 1 Bridge, Guangming No. 2 Bridge, Longchi Creek Bridge and Dashuizhong Bridge within the section of FJ-1A of Pu Railway, The relationship between construction technology and pile quality, common construction quality problems and prevention measures.
