在铁路工程建设中,经常会用到粉喷桩技术来处理软基,这也是充分结合其施工便捷、工期短、施工效果好等优点的有效做法。在施工过程中,经常会遇到技术难度大、后期维护难等问题,这也是施工过程中的一些阻碍。本文从粉喷桩处理铁路软土地基中的施工工艺和质量控制展开研究,对其中的技术应用要求、工艺流程、质量控制措施做了详尽的分析,希望对相关人士有所帮助。
In the railway construction, often use the technology of powder jetting pile to deal with soft foundation, which is also an effective way to fully combine the advantages of its convenient construction, short construction period and good construction effect. In the construction process, often encounter technical difficulties, the latter part of the maintenance of difficult issues, which is also some obstacles in the construction process. In this paper, the construction technology and quality control of DJM pile in soft soil foundation are studied. The technical application requirements, process flow and quality control measures are analyzed in detail, and it is hoped that it will be helpful to those involved.
