大直径长螺旋灌注桩在基坑支护中的应用分析

Application Analysis of Large Diameter Long Spiral Grouting Pile in Foundation Pit Support

随着现代施工技术的发展,出现了一大批新型桩基施工技术,其中最具有代表性的就是大直径长螺旋灌注桩。通过此种施工方法,不仅可以实现钻孔施工,还可以进行混凝土压灌施工,避免多个专业与设备交叉施工,以此提升混凝土灌注速度及成桩质量。本次研究联合实际工程案例,分析了大直径长螺旋灌注桩在基坑支护中的应用,同时提出施工质量控制措施,以期能够为相关人员提供参考价值。

With the development of modern construction technology,a large number of new pile foundation construction technologies have appeared,the most representative of which is the large diameter long spiral cast-inplace pile.Through this construction method,not only the drilling construction but also the concrete pressure irrigation construction can be carried out,avoiding the cross construction of multiple specialties and equipment,so as to improve the concrete pouring speed and the pile forming quality.This study,combined with actual engineering cases,analyzes the application of large-diameter and long-screw cast-in-place piles in foundation pit support,and at the same time proposes construction quality control measures in order to provide reference value for relevant personnel.
