Anti-erosion sewage pipe and preparation method thereof
The invention relates to an anti-erosion sewage pipe and a preparation method thereof, and belongs to the technical field of water environment treatment. The pipe wall of the sewage pipe consists of an inner layer, a middle layer and an outer layer; the inner layer is made of a high-erosion-resistance cement-based material, the middle layer is made of a high-adhesion inorganic adhesive, the outer layer is made of low-carbon cement concrete, and a reinforcing mesh is embedded in the concrete to serve as a supporting framework; the thickness ratio of the inner layer to the middle layer to the outer layer is 1: (0.2-0.4): (2-5); the cement-based material with high erosion resistance is a cement-based material with the pH value of 9.5 to 11.5; the high-adhesion inorganic adhesive is a phosphorus and magnesium based inorganic cementing material; the inner layer of the sewage pipe is low in alkalinity and good in microbial erosion and sulfate erosion resistance; the middle layer is good in bonding performance and firmly bonds the inner and outer layers; the outer layer is made of low-carbon cement concrete, and the carbon emission of the outer layer is less than 50% of that of traditional Portland cement, so that the sewage pipe has excellent corrosion resistance and is green, low-carbon and environment-friendly.
本发明涉及一种抗侵蚀污水管及其制备方法，属于水环境治理技术领域。所述污水管的管壁由内层、中层和外层组成；内层材料为高抗侵蚀水泥基材料，中层材料为高粘结无机胶粘剂，外层材料为低碳水泥混凝土，所述混凝土内部包埋有钢筋网作为支撑骨架；内层、中层和外层的厚度比为1：(0.2～0.4)：(2～5)；所述高抗侵蚀水泥基材料为pH值为9.5～11.5的水泥基材料；所述高粘结无机胶粘剂为磷镁基无机胶凝材料；所述污水管内层碱度低、抗微生物侵蚀及硫酸盐侵蚀性能好；中层粘结性能好、牢固粘结内外层；外层为低碳水泥混凝土、其碳排放不到传统硅酸盐水泥50％，从而确保所述污水管在具有优异耐腐蚀性能的同时，绿色低碳环保。
