桩基础底部溶洞多孔高压射流后压浆技术研究
发布时间：2018-11-19 18:45
【摘要】：岩溶地区地质情况复杂,部分桥梁桩基础位置常常处于溶(土)洞影响的范围内,影响桥梁结构安全,常规处理方法主要是通过加长桩基础穿过不良地层或施工前预先处理,但对成桩后发现较大溶洞处理技术一直是桥梁技术难点,结合实际工程研究,采用多孔高压射流对成桩后发现的桩底溶洞进行压浆处理。
[Abstract]:The geological conditions in karst area are complex, some bridge pile foundation location is often in the range of dissolving (soil) hole influence, which affects bridge structure safety. The conventional treatment method is mainly through lengthening pile foundation through bad stratum or pre-treatment before construction. However, it is always difficult for bridge to find large caverns after piling. Combined with practical engineering research, the porous high pressure jet is used to deal with the grouting of caverns found after piling.
