大川坝位于日本阿贺野川上游,是一座防洪、城市供水和发电的综合利用工程。预计1979年开始浇筑坝体混凝土,大坝将于1983年建成。该工程的上游围堰为一座混凝土重力坝,高19米,长102.5米,混凝土量约1万立米。为了试验研究一种造价省、工期短的混凝土坝新施工方法,因此决定在大川坝上游围堰试验用振动辗辗压混凝土的筑坝方法施工。混凝土用自卸卡车进仓,推土机平仓,振动辗压
Okawa Dam is located in the upper reaches of Agano River in Japan and is a comprehensive utilization project of flood control, urban water supply and power generation. It is estimated that the dam concrete will be poured in 1979 and the dam will be completed in 1983. The project’s upstream cofferdam is a concrete gravity dam, 19 meters high, 102.5 meters long and about 10 thousand cubic meters of concrete. In order to experimentally study a new construction method of concrete dam with low cost and short construction period, it is decided to construct a cofferdam by vibrating roller-rolling concrete method in the upstream cofferdam of Dachuanba.
