Anti-corrosion, anti-freezing and anti-cracking reinforced concrete culvert pipe
The invention relates to the technical field of culvert pipes, in particular to an anti-corrosion, anti-freezing and anti-cracking reinforced concrete culvert pipe which comprises reinforcing steel bars, concrete and coating; the concrete is prepared from, by weight, 300-400 parts of Portland cement, 600-750 parts of sand, 1000-1200 parts of gravel, 110-130 parts of water, 3-8 parts of water reducing agent and 50-130 parts of steel fiber; and the coating comprises the following raw materials in parts by weight: 70-80 parts of epoxy resin, 60-120 parts of an organic solvent, 12-25 parts of modified nano filler and 5-8 parts of a curing agent. The coating is sprayed on the surface of the pipeline, the coating contains a large number of fat hydroxyl groups and ether bonds and has high adhesive force, a coating film formed on the surface of the pipeline is stable and small in air hole, permeation of various media is effectively blocked, a connection effect is achieved between concrete, and then the freezing resistance and the overall strength of the pipeline are improved; in addition, the coating is sprayed on the surfaces of the steel bars and the steel fibers, so that the protection effect and the corrosion delaying effect on the steel bars and the steel fibers are improved, and the quality of the pipeline is guaranteed.
本发明涉及涵管技术领域，具体为一种防腐抗冻抗开裂的钢筋砼涵管，该钢筋砼涵管包括钢筋、混凝土和涂料，混凝土包括以下重量份原料：硅酸盐水泥300‑400份、砂子600‑750份、碎石1000‑1200份、水110‑130份、减水剂3‑8份、钢纤维50‑130份；涂料包括以下重量份原料：环氧树脂70‑80份、有机溶剂60‑120份、改性纳米填料12‑25份、固化剂5‑8份；本发明通过在管道表面喷涂涂料，涂料中含有大量的脂肪羟基和醚键，具有较强的附着力，且在管道表面形成的涂膜稳定，气孔小，有效的阻挡各种介质的渗入，在混凝土间起到连接作用，继而提高了管道的抗冻性和整体强度；此外，本发明通过在钢筋和钢纤维表面喷涂涂料，提高了对钢筋和钢纤维的保护作用，延缓锈蚀作用，保证了管道的质量。
