Analysis of foundation reinforcement technology for sash-shaped underground continuous wall
The construction area of the sash-shaped underground continuous wall of vertical guide wall foundation in Shaping Ⅰ hydropower station is located on a soil layer of mud gravel,fine sand and silt. The bearing capacity of foundation is low,and the groundwater on the right bank converges on the con-struction platform,causing severe water accumulation on site,leading to the collapse of guide wall. By adopting measures such as drainage through precipitation wells,adjusting the size of guide walls,and adding temporary friction piles at the position of the second step slot,the foundation was appropriately re-inforced,which effectively solved problems of construction platform foundation deformation,slot hole col-lapse and so on. Practice has shown that the above reinforcement measures are safe,effective and feasi-ble for soft and hard alternating foundation,and can provide reference for similar projects.
