摘要
结合钻孔灌注桩桩底后注浆技术在温州灵溪镇卵砾石地层中的成功应用,分析了桩底后注浆提高单桩承载力的原理,详细阐述了桩底后注浆技术工艺流程及施工技术要点,以推广该施工工艺。
Combined with successful application of filling slurry technology used for the bottom of broach-douche peg in pebble-gravel stratum in Linwen,Wenzhou.It analyzes the principle of filling slurry at the bottom of peg in increasing supporting force of single peg and expounding marrows of technology when using it so as to generalize this technology.
