Design and Construction Technology of Bored Pile in a Wharf in Republic of Liberia
Abstract:A wharf reconstruction project lies in Monrovia, Republic of Liberia, where the silt and silt clay formations are thick with high compressibility and thixotropic. Considering the factors of stratum conditions, construction equipments, project period and project cost, the bored pile is designed according to the related standard and according to the site conditions and the characteristics of the bored grouting pile, and the construction process is formulated. The quality control measures are put forward for the problems of water oozing from casing, drilling tool sticking and grouting pipe blocking in bored grouting pile construction.
