Abstract:
During engineering construction of Huangpu Avenue-Jinqiao Boulevard Expressway project, new drilling technique with combination of rotary drill and hammer drill and related technical construction measures are adopted to solve the technical construction problems during drilling large holes on deep and thick rock. Their own characteristics and efficiencies of all equipments are well exerted to successfully shorten construction period and save construction cost.
