摘要
普通挤扩支盘桩只适用于小直径和桩长有限的稳固地质,为提高固结扩盘桩施工技术水平,论文结合实际工程,围绕固结扩盘桩施工技术的总体技术方案内容和具体施工要点展开详细的探讨。经过实践,最终提高了该工程的成桩质量,减少了施工风险,取得了良好的应用效果。
Ordinary extruded expanded branch pile is only suitable for small diameter and limited pile length of stable geology,in order to improve the construction technology level of consolidation expanded disk pile,combined with the actual project,the paper discusses in detail the overall technical scheme content and specific construction key points of consolidation and expansion disk pile construction technology.Through practice,the quality of pile forming is improved,the construction risk is reduced,and good application effect is achieved.
