「The 175 m-long pier superstructure was divided into 3 precast members, each with a maximum length of 58.4 m and weight of 1,660 t, and the Company's smart connection technology was used to join them. Installation using a 2,200 t crane vessel was completed in 3 days.」
The project progressed from developing a pile-head connection structure for precast-concrete piers to rapid construction in an actual project using large precast members and smart connection technology. - FY2020AdvancedAnnual report
「The technology was adopted for a construction project ordered by the Tohoku Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism, achieving an approximately 30% reduction in the construction period for the superstructure beams compared with conventional cast-in-place concrete construction.」
The pile-head connection structure for precast-concrete piers was applied to an actual construction project, achieving an approximately 30% reduction in the construction period compared with the conventional method. - FY2019RestatedAnnual report
「Through joint research with Tokyo Institute of Technology and the National Institute of Maritime, Port and Aviation Technology, the Company developed, through structural testing, a pile-head connection structure with excellent structural performance (straight piles: sleeve-pipe method; batter piles: socket-rebar method).」
The Company continues to develop pile-head connection structures for various precast-concrete pier configurations through joint research with universities and research institutions. - FY2018First statedAnnual report
