钻孔灌注桩在黄田水库输水塔工程中的应用

摘要

对黄田水库输水塔工程塔体结构和基础地质情况进行了简要分析，提出了采用钻孔灌注桩进行基础处理的技术方案以及相应的设计参数。从护筒埋设、成孔、清孔等方面，阐述了钻孔灌注桩的施工技术要点，采用反射波法进行检测，工程质量符合设计要求。%body structure and fundamental geological condition of Huangtian reservoir intake tower project are briefly analyzed in this article.On this basis, bored pile technology is suggested to improve a foundation , and relevant design parameter is supplied . From the aspects of the embedment of the steel casing , pore -forming and pore -clearing, several key points of bored pile construction technology are illustrated in this article .Furthermore, the project meets design requirement which was inspected by the reflected wave method .
