摘要
金属管道在含水量大、化学成份复杂的近海软土中易发生锈蚀。采用水泥、石灰、粉煤灰、磷石膏等和管沟挖出土搅拌混和后形成人工土,置于金属管道四周,可以较好地保护金属管道。
Soft soft in the offing with high moisture capacity and complex chemical composition will rust the metal pipeline.So the mix- ture of Cement,Lime,Coal-ash powder,Phosphoric gesso and Soil is demanded to put around the metal pipeline to protect it.
