Abstract:
Taking the construction of the bored castinsitu concrete piles in a large electricity power plant in Jiangxi province as example, the article presents the geological conditions and the karst development features of the site. On basis of the construction process of the bored castinsitu concrete piles in such geological conditions and problems encountered during construction, such as hole collapse, hole inclination, hole connection, grout leakage, drilling tool blocking, drilling tool dropping and pile body concrete sinking, the article analyses on the causes for the problems and recommends some detailed prevention and treatment countermeasrues.
