摘要
为缩短工期,提高施工效率,创设了一种变截面钻孔灌注桩水下一次成型浇筑法。在介绍工程概况、分析技术难点后,详细介绍技术方案。发明一种新型钢护筒,实现水下钻孔灌注桩桩帽、桩身的整体浇筑、一次成型,被工程实践证明质量可靠,并获得专利授权。
In order to shorten the constructive period and improve the working efficiency, we create a method of one-step forming under water of a varied section drilling pile. Based on the introduction of the engineering condition and technical difficulties, this paper analyzes the technical plan in detail. A new steel protecting tube is invented to realize integral pouring of pile cap and pile body under water and one-step forming of the drilling pile, which is proved to be reliable in engineering quality by the practical engineering and obtains a patent license.
