由中冶建筑研究总院有限公司和中国京冶工程技术有限公司主持研发的“双向螺旋挤土灌注桩成套关键技术”项目,日前荣获2013年度华夏建设科学技术奖三等奖。双向螺旋挤土灌注桩(简称SDS桩)是具有显著技术、环保和成本优势的新型桩基技术,在成桩过程中,通过特种挤扩钻头实现完全不排土或者控量排土,从而使桩周和桩端土体挤密,进
Developed by China Metallurgical Construction Research Institute Co., Ltd. and China Jing Ye Engineering Technology Co., Ltd., “Key Technology of Bidirectional Spiral Compaction Pile” has won the third prize of 2013 Huaxia Construction Science and Technology Award. The bidirectional screw squeezing and pouring pile (referred to as SDS pile) is a new type of pile foundation technology with significant technical, environmental and cost advantages. During the pile-forming process, the special uncrowded drill bit achieves complete soil drainage or controlled draining so that Pile weeks and pile-end soil compaction, into
