The invention relates to the technical field of grouting materials, and discloses a grouting material aiming at a concentrated water leakage defect, which is prepared from the following raw materials in parts by weight: 25 to 55 parts of cement paste, 30 to 60 parts of nano calcium hydride, 25 to 65 parts of expansive resin, 35 to 55 parts of polyurethane foam, 40 to 60 parts of epoxy resin, 45 to 75 parts of early strength agent, 40 to 65 parts of expanding agent and 25 to 40 parts of mineral admixture. According to the grouting material for the concentrated water leakage defect and the grouting method of the grouting material, the polyurethane foam and the nano calcium hydride are added into the grouting material, cracks and holes can be rapidly filled by utilizing the rapid expansion and curing characteristics of the polyurethane foam, a firm plugging layer is formed, the water leakage defect can be rapidly plugged, and the water leakage defect is prevented from being damaged. Meanwhile, nano calcium hydride can be utilized to form calcium stone in the concrete to fill microcosmic cracks, so that the durability and impermeability of the concrete are improved, and the problem that in the prior art, grouting materials mainly comprise cement-based grouting materials and water glass grouting materials is solved.
本发明涉及灌浆材料技术领域，且公开了一种针对集中渗漏水缺陷的灌浆材料，包括以下重量份数配比的原料：水泥浆25—55份、纳米氢化钙30—60份、膨胀树脂25—65份、聚氨酯泡沫35—55份、环氧树脂40—60份、早强剂45—75份、膨胀剂40—65份、矿物掺合料25—40份。该针对集中渗漏水缺陷的灌浆材料及其灌浆方法，通过在灌浆料中加入聚氨酯泡沫和纳米氢化钙，利用聚氨酯泡沫快速膨胀和固化的特性，可以迅速填充裂缝和孔洞，并形成坚固的封堵层，可以快速对漏水缺陷处进行封堵，同时可以利用纳米氢化钙在混凝土内部形成钙石，填充微观裂缝，提高混凝土的耐久性和抗渗性能，解决了现有技术中的灌浆材料主要以水泥基灌浆材料和水玻璃类灌浆材料为主。
