Method for repairing tunnel crack in seasonal frozen area
The invention provides a method for repairing tunnel cracks in a seasonal frozen area, and relates to the field of disaster prevention and reduction. Materials used in the method mainly comprise urea, calcium chloride, rubber powder and a plant urease solution, the materials are evenly mixed according to a specific proportion, and the crack is filled with the mixture through a caulking gun so that the crack can be repaired. The rubber powder used in the method is prepared by crushing waste tires, has non-hydrophilicity and excellent anti-freezing performance, and has no damage to the environment and human health. According to the method, urea, calcium chloride and plant urease are subjected to an EICP reaction to generate calcium carbonate precipitates, the precipitates exist among rubber powder particles and bond the rubber powder particles into a whole, and the EICP and the rubber powder are jointly used, so that the repairing agent has good anti-freezing and anti-seepage performance, cracks are repaired, and the waterproof and anti-seepage performance is excellent. The method is convenient, fast, economical and applicable, and belongs to an environment-friendly solid waste resource utilization method.
本发明提供一种修复季冻区隧道裂缝的方法，涉及防灾减灾领域。本方法中所用材料主要包括尿素、氯化钙、橡胶粉和植物脲酶溶液，将上述材料按照特定比例混合均匀，用压胶枪将其填充至裂缝内，使裂缝得以修复。此方法中所用橡胶粉为废旧轮胎破碎制得，橡胶粉具有非亲水性和优良的防冻性能，对环境及人体健康无任何损害。该方法中，尿素、氯化钙与植物脲酶发生EICP反应产生碳酸钙沉淀且该沉淀存在于橡胶粉颗粒之间并将其粘结成一个整体，EICP与橡胶粉的联合使用，使得修复剂具有良好的抗冻防渗性能，不仅使裂缝得以修复，且防水抗渗性能极佳。该方法方便快捷、经济适用，属于环保型固废资源利用的方法。
