Construction Technology of Ultra Deep Rock Underground Continuous Wall Trenching under High Groundwater Condition
This paper introduces the key technology for the construction of deep underground continuous wall vertical shafts in hard rock geology with mixed fractured zones under high groundwater levels.The specific measures are to install high-pressure rotary jet grouting piles and curtain grouting around the vertical shaft to prevent water and seepage,and improve the stability of the trench wall during the trenching period.By utilizing a combination of rotary drilling,slotting machines,impact hammers,and milling machines to create slotting in different geological formations,the construction efficiency of ultra deep connected wall slotting in hard rock fracture zones can be improved,ensuring construction progress.
