Non-excavation type grouting material for rapid treatment of bridgehead pavement subsidence
The invention discloses a non-excavation type grouting material for rapid treatment of bridgehead pavement subsidence. The grouting material comprises a component A and a component B, wherein the component A is a main agent and is prepared from the following raw materials in parts by mass: 50-60 parts of epoxy resin, 10-30 parts of polyether polyol, 10-15 parts of nano active calcium carbonate, 5-7 parts of an expanding agent, 1-2 parts of an anti-aging agent, 1-3 parts of a defoaming agent, 1-2 parts of a plasticizer, 0.5-1 part of a catalyst and 0.5-1 part of a coloring agent; and the component B is a curing agent and is prepared from the following raw materials in parts by mass: 30-60 parts of isocyanate, 10-30 parts of molecular sieve activation powder, 20-30 parts of polyester polyol, 7-9 parts of a polymerization inhibitor and 1-3 parts of a water removal agent. The non-excavation, rapid and effective grouting reinforcement material based on bridgehead pavement void and subsidence disease treatment solves the industrial problems that in bridgehead pavement subsidence disease treatment, the excavation scale is large, the construction difficulty is large, thorough treatment is difficult, and traffic interference is large.
本发明公开了一种桥头路面沉陷非开挖式快速处治注浆材料；包括A、B两个组分；其中A组分为主剂，由下述质量份数的原料制得：环氧树脂50～60份、聚醚多元醇10～30份、纳米活性碳酸钙10～15份、膨胀剂5～7份、抗老化剂1～2份、消泡剂1～3份、增塑剂1～2份、催化剂0.5～1份、着色剂0.5～1份；B组分为固化剂，由下述质量份数的原料制得：异氰酸酯30～60份、分子筛活化粉10～30份、聚酯多元醇20～30份、阻聚剂7～9份、除水剂1～3份。本发明所提供的一种基于桥头路面脱空、沉陷病害处治的非开挖、快速有效的注浆加固材料，解决桥头路面沉陷病害处治开挖规模大、施工难度大、难以彻底处治、以及对交通干扰大的行业难题。
