日本钢管公司开发了高炉渣应用新技术,将细粒化的高炉渣覆盖在海床上,以隔绝海边富集的胶质泥沙。该公司最近已将炉渣运往国土和运输部以掩埋海床。日本钢管公司已有54000t高炉渣被逐渐运往海边,覆盖在日本沿海的海岸上。目前已有40000m~2(10英亩)的海岸被充填,厚度高达15mm以上。
Nippon Steel Pipe Co., Ltd. developed a new technology for the application of blast furnace slag to cover the seafloor with fine-grained blast-furnace slag in order to cut off the silty sediment enriched in the seaside. The company has recently shipped slag to the Ministry of Lands and Transport to bury the seabed. Japan Steel Pipe Company has 54,000 tons of blast furnace slag has been gradually transported to the coast, covering the coast of Japan. At present, 40,000m2 (10 acres) of coast have been filled with thicknesses of up to 15mm.
