Reinforced protective layer concrete structure of viaduct pier
The invention relates to the field of viaduct pier manufacturing, in particular to a viaduct pier reinforcement protective layer concrete structure which comprises a reinforcement cage, and a concrete layer is poured on the outer side of the reinforcement cage. The concrete layer is prepared from 100 to 160 parts of modified cement, 200 to 300 parts of coarse aggregate, 100 to 200 parts of steel fiber, 20 to 60 parts of reinforced resin, 10 to 30 parts of a water repellent agent, 20 to 60 parts of a water reducing agent, 10 to 20 parts of a hole sealing agent and 10 to 20 parts of an anti-freezing agent. The aggregate is the coarse aggregate with more uniform particle size and is not doped with any fine aggregate, so that the water permeability and the air permeability of the concrete are better, and the coarse aggregate, the modified cement, the steel fibers and the reinforced resin are mutually mixed, so that the overall strength of the concrete is improved, and the carbonization resistance and the chloride ion erosion resistance of a viaduct pier concrete layer are improved; and the service life of the viaduct pier is prolonged.
本发明涉及高架桥墩制造领域，具体涉及一种高架桥墩钢筋保护层混凝土结构，包括钢筋笼，所述钢筋笼的外侧浇筑有混凝土层；所述混凝土层包括有改性水泥100～160份、粗骨料200～300份、钢纤维100～200份、强化树脂20～60份、疏水剂10～30份、减水剂20～60份、封孔剂10～20份、防冻剂10～20份。本发明中骨料采用粒径更加均匀的粗骨料，不掺杂任何细骨料，使得混凝土的透水透气性能更好，并将粗骨料、改性水泥、钢纤维和强化树脂相互混合，提高混凝土的整体强度，提升高架桥墩混凝土层的抗碳化以及抗氯离子侵蚀性能，延长高架桥墩的使用寿命。
