溶洞区桩基施工

在公路铁路基础建设工程中,常会遇见溶洞、流砂层、地下暗河等特殊地质情况.基于江西武吉高速C2标特殊地质区的桩基工程,分析了地质地貌条件、地质勘探以及特殊地质情况的产生机理.并介绍了桩基施工的准备工作和工艺流程.针对在施工过程中所遇到的坍孔、漏浆、桩位整体下陷等突发现象,提出了有效的解决措施, .以做好成本控制,保证桩基施工顺利完成.

Pile Foundation Construction in Cavern Zone

Special geological conditions including karst cave,flow sand seam and underground river are encountered during construction of railway and highway engineering.Based on the pile engineering under special geological area of Wuji expressway No.C2 in Jiangxi,geology geomorphology,geological exploration and generation mechanism of special geological conditions are analyzed.At the same time,preparation work and technology flow of pile construction are introduced in this paper.Some effective measures are put forward to control cost according to sudden phenomena including hole collapse,mud leakage and integral sinking of pile location,which can ensure successful accomplishment of pile construction.
