Hybrid fiber ultra-high performance concrete (UHPC) electric pole and manufacturing method thereof
The invention belongs to the field of electric power engineering, and particularly relates to a hybrid fiber ultra-high performance concrete (UHPC) electric pole and a manufacturing method thereof, wherein the UHPC used by the electric pole is formed by combining cement, silica fume, quartz sand with different gradations, broken stones, an additional high efficiency water reducer, water, polypropylene fibers and basalt fibers according to a certain proportion. The cement is 42.5-grade ordinary silicate, the water reducer is a novel non-naphthalene high-performance water reducer AN4000, and theslurry is uniform and compact. Due to the fact that the basalt fibers and the polypropylene fibers are added, the crack resistance and durability of the UHPC electric pole are greatly improved. The electric pole is quite suitable for harsh corrosive environments in coastal areas, and the phenomenon of steel fiber corrosion after steel fibers are added is avoided while the strength is improved. The raw materials used in the invention are common industrial raw materials, the production cost is greatly reduced, the preparation method is simple, and the electric pole has wide application value inthe fields of concrete electric pole cast-in-place and corrosion resistance.
本发明属于电力工程领域，具体涉及一种混杂纤维超高性能混凝土（UHPC）电杆及其制作方法，该电杆使用的超高性能混凝土由水泥、硅灰、不同级配石英砂、碎石、外加高效减水剂、水、聚丙烯纤维和玄武岩纤维按一定比例组合而成。所述水泥为42.5标号普通硅酸盐，减水剂为新型非萘系高性能减水剂AN4000，浆体均匀密实。由于加入了玄武岩纤维和聚丙烯纤维纤维，大大提高了超高性能混凝土电杆的抗裂性及耐久性。该电杆十分适用于沿海地区严酷的腐蚀环境，在提高强度的同时避免了加入钢纤维后发生的钢纤维腐蚀现象。本发明所用原料都为普通工业原料，大大降低了生产成本，制备方法简单，在混凝土电杆现浇及抗腐蚀领域有广泛应用价值。
