摘要
北京丰台区域6 m深度以下为砂卵石地层,该地层级配很差、自稳性差,采用三重管进行加固处理。三重管即用浆、气、水三种介质同时作用于地层,使浆液与地层颗粒成份搅拌、混合、置换、充填渗透最终形成固结体。
Six meters below Fengtai area in Beijing is sand-pebble layer,which is poor in gradation and stability and needs strengthening of triple tube technology,which applies slurry,gas and water on the layer to realize mixing,replacement and filling between the grout and stratum to become concrete.
