Based on 1.7 m thick diaphragm wall of car dumper shed at Caofeidian coal terminal, key construction techniques of ultra-high diaphragm wall was summarized according to the experiences in diaphragm wall construction over years. The construction of ultra-high diaphragm wall was analyzed from the aspects of soil body reinforcement, trenching, reinforcing cage fabrication and installation and pull-out of junction pipe. The project showed that no safety or quality accident occurred in the construction, and no water leakage existed in the post-excavation of car dumper shed. The successful application of ultra-high diaphragm wall served as a reference for the design and construction of similar foundation pit in housing and municipal projects.
