咬合桩在深基坑工程中的应用

APPLICATION OF SECANT PILE IN DEEP FOUNDATION PIT ENGINEERING

随着中国经济的发展,城镇化建设进程不断加快,深基坑工程越来越多。钻孔咬合桩有整体刚度大、抗渗性能好等特点而作为深基坑工程的一种支护结构形式被应用。以邻近地铁基坑工程实例为背景,介绍钻孔咬合桩在深基坑支护工程中应用情况以及咬合桩施工质量控制要点,以期有效发挥其技术作用,在建筑行业中类似工程借鉴。

With the development of China’s economy and the accelerating process of urbanization, there are more deep foundation pit projects. With the characteristics of large overall stiffness and good permeability resistance, bored secant pile is applied as a support structure form of deep foundation pit engineering. Based on the example of foundation pit engineering adjacent to subway, this paper introduces the application of drilling secant pile in deep foundation pit support engineering and the key points of secant pile construction quality control, in order to effectively play its technical role and learn from similar projects in the construction industry.
