| Abstract: | The method of balancing the pressure between each caisson was used for steel casing installation in reconstruction project.Then the hole was filled in to give the steel casing greater stability.Cross hammer was used for piercing through the floor at the bottom of caissons.The mix ratio of slurry and the method of cleaning hole and draining residue were successfully used in the construction of rock-socketed pile embedded through the bottom plate of caisson.This new construction technique for rock-socketed pile embedded through the bottom plate of caisson has important practical and engineering significance. |
