介绍了一种新型的微型桩成桩方法——灌注细石混凝土成桩法,并通过浙江地区典型软土地基中进行的现场施工,对该方法的施工流程及施工参数进行了研究,提出了相应的施工工艺。通过上拔试验对其抗拔承载力进行了研究,试验研究表明,只要合理地控制好施工参数,采用微型桩灌注细石混凝土成桩是切实可行的方法,在今后的工程中可以进一步应用和研究。 This paper introduces a new type of micro-pile forming method-grouting fine-grained concrete pile-forming method. Through the on-site construction in typical soft soil foundation in Zhejiang Province, the construction process and construction parameters of this method are studied. The corresponding construction process. Through the pull-up test, its anti-pull bearing capacity was studied. The experimental results show that as long as the construction parameters are properly controlled, it is feasible to use micro-pile to pour fine aggregate concrete into piles, which can be further applied in future projects. the study.
