岩溶地区旋挖桩成孔质量控制技术研究

Study on Pore Forming Quality Control Technology of Rotary Digging Pile in Karst Region

随着建筑业的飞速发展,云南省的土地开发需求量大幅增加,近年来,岩溶地区的土地资源逐渐被开发利用,岩溶地区的桩基施工作为建设中的一大难题也越来越受到重视。本文根据作者多年在岩溶地区旋挖桩的施工经验,针对不同的岩溶发育情况,提出了相应的处理方案。以实际工程为例,对岩溶地区桩基施工过程中出现的质量问题进行分析,提出了相应的处理措施,对处理效果进行相应分析,其经验可以作为同行在类似地层进行施工质量控制的参考。

With the rapid development of the construction industry,the demand for land development in Yunnan has increased significantly.In recent years,land resources in the karst areas have gradually been developed and utilized.The pile foundation construction in the karst area has become a major problem in the construction.According to the author’s construction experience in the mute tractor in the karst region,this paper proposes a corresponding processing plan for different karst development.Taking the actual project as an example,the quality problems of the pile foundation in the karst area are analyzed.According to the corresponding treatment,corresponding analysis of the treatment effect are conducted,and its experience can be used as a reference quality control in similar formations.
