超长灌注桩钢筋笼安装施工技术

Installation and Construction Technology of Reinforcement Cage for Super Long Cast-in-place Pile

根据厦门白鹭西塔项目桩基础施工经验,从大直径超长灌注桩钢筋笼的制造、安装、质量管理等环节出发,对钢筋笼施工质量和安装过程中的质量管理要求加以详尽介绍,探讨该施工技术在本工程应用的特点及难点,同时也为今后类似地质条件下大直径超长钻孔灌注桩的钢筋笼安装施工提供了宝贵的经验。

According to the pile foundation construction experience of Xiamen Bailu West Tower Project,starting from the manufacturing,installation,quality management and other links of large-diameter and super long cast-in-place pile reinforcement cage,the construction quality of reinforcement cage and the quality management requirements in the installation process are introduced in detail,and the characteristics and difficulties of the application of this construction technology in this project are discussed,At the same time,it also provides valuable experience for the installation and construction of reinforcement cage of large-diameter and super long bored pile under similar geological conditions in the future.
