Key Technology Analysis of Construction of Joint-Pipe Method for Ultra-Deep Diaphragm Wall
Based on a ultra-deep diaphragm wall of Pangduo hydropower station, time of pipe drawn and drawn force under different times and hole deviation was researched. Field test was used to verify analysis conclusion. The results show that drawn time is 7~8 hours after concrete pouring, that is 40m high concrete after pouring. Several factors has effect on drawn force which relates to contact characters between sliding pipe and concrete and hole deviation.
