1、化工厂房工程地基的选择由于化工生产中常有大量含腐蚀性介质的污水排放,浸入地下后对厂房地基造成腐蚀,危及厂房的安全,因此针对不同的腐蚀性介质选择适当的工程地基,并采取相应的防护措施,应予必要的重视。a)粘土或亚粘土地基:一般厂房基础大都置于粘土或亚粘土层上。对于此类地基土必须做土体结构的化学成份分析和物理性能的测定。土体中含有大量的有机物时对防腐蚀极为不利。土体的容重、孔隙比、含水量、塑性指数等物理性能与防腐蚀有着密切的关系。粘土有
1. Selection of Foundation for Chemical Plant Engineering Due to the large amount of wastewater containing corrosive medium in chemical production, the ground of the plant is eroded after being immersed in the ground, which endangers the safety of the plant. Therefore, suitable engineering foundations are selected for different corrosive media, and Take appropriate protective measures, should be given the necessary attention. a) Clay or sub-clay ground: Most of the factory building foundation is placed on a clay or sub-clay layer. For such ground-based soils, chemical composition analysis and physical properties of the soil structure must be determined. Soils containing large amounts of organic matter are extremely detrimental to corrosion protection. Soil bulk density, void ratio, water content, plasticity index and other physical properties are closely related to corrosion protection. Clay has
