The invention discloses a chemical grouting material for urban subway construction and a method thereof. The chemical grouting material is prepared by matching a component A and a component B, wherein the component A is prepared from the following raw material components: superfine cement, quartz sand, an early strength agent, a water reducing agent, a retarder and a defoaming agent; the component B is prepared from the following raw material components: polyurethane, modified epoxy resin, a curing agent and a diluent. The components of the chemical grouting material for subway construction are improved, water-soluble polyurethane and modified epoxy resin are added, and superfine cement is selected, so that on one hand, the hydrophilic performance of the annular grouting material is improved, and on the other hand, the annular grouting material adapts to mixing of different water qualities; the chemical grouting material can be quickly coagulated in a humid and dark environment, meanwhile, the structural strength is high, the subway construction efficiency is improved, and the structural strength of subway construction is guaranteed.
本发明公开了一种城市地铁施工的化学灌浆材料及其方法，化学灌浆材料包括A组分和B组分配合调制配置：其中A组分由以下原料成分组成：超细水泥、石英砂、早强剂、减水剂、缓凝剂和消泡剂；B组分由以下原料成分组成：聚氨酯、改性环氧树脂、固化剂和稀释剂。本发明通过对地铁施工的化学灌浆材料的成分进行改进，通过水溶性聚氨酯、改性环氧树脂的添加和超细水泥的选择，一方面提高了环形灌浆材料的亲水性能，另一方面适应不同水质的混合，通过改变化学灌浆材料的结构性能，使化学灌浆材料能够在潮湿和阴暗的环境下快速的凝结，同时结构强度高，不仅提高了地铁修建的效率，而且保证了地铁修建的结构强度。
