Abstract

Abstract: The geological conditions at the pumpedstorage power plant in Huizhou City are very complicated. Difficulties were encountered during the construction of concrete diaphragm walls. A different drilling method, namely, drilling and impacting method, was used after the construction difficulties were encountered. The post construction test boring and Ground Penetration Radar survey indicated that his method was proved to be successful and the design requirements were achieved.

Key words: Concrete Diaphragm Walls, Drilling Methods, Construction Techniques, Design Parameters
