复杂地质条件下微型嵌岩钢管灌注桩施工技术

Built-in Mini Steel Pipe Pile Construction Technique Under Complicated Geological Conditions

钢管灌注桩施工是珠江堤岸环境改造工程沿江路人行道悬飘段工程的重点和难点，在施工过程中存在地质复杂、工期紧、工作面狭长、管理难度大等特点．本文通过介绍如何克服复杂地质条件下微型嵌岩钢管灌注桩施工的困难，深入阐述嵌岩钢管灌注桩的施工方法和技术．

Steel pipe pile construction is the key and major part of the working operation to the suspended pavement section of Yanjian Road that is the part of the Pearl River embankment environmental improvement project. The build-ing site has complicated geoloical conditions, along with tight project period, narrow working face, and hard task man-agement. By introducing how to overcome the built-in mini steel pipe operation problems under complicated geological conditions, the paper deeply elaborates the built-in steel pipe pile construction techniques.
