The invention relates to the technical field of building materials, and discloses a high-impermeability cement-based repair material for tunnel engineering and a preparation method thereof, and the high-impermeability cement-based repair material comprises the following raw materials: Portland cement, quartz sand, fly ash, inorganic bentonite, an active catalyst, desulfurized gypsum, a polycarboxylic acid water reducer, cellulose ether, polyacrylamide, wood fiber, a defoaming agent and water. The high-impermeability cement-based repair material has the advantages of high fracture resistance, high compressive strength, high bonding strength, high impermeability grade, high impermeability pressure, low dry shrinkage rate, durability and the like; the problem of poor self-waterproof performance of tunnel lining concrete in tunnel engineering can be solved, a tunnel lining structure which is corroded and degraded by leaked water can be repaired, the problem of tunnel water leakage is solved, the problem of poor self-waterproof performance caused by insufficient compactness, shrinkage cracking or temperature load stress cracking and the like of traditional lining concrete is solved, and the service life of the tunnel lining concrete is prolonged. And the degraded traditional lining concrete can be repaired and maintained in time, and the problem of water leakage in tunnel engineering is solved.
本发明涉及建筑材料技术领域，且公开了用于隧道工程的高抗渗水泥基修复材料及其配制方法，包括以下原材料组成：硅酸盐水泥、石英砂、粉煤灰、无机膨润土、活性催化剂、脱硫石膏、聚羧酸系减水剂、纤维素醚、聚丙烯酰胺、木质纤维、消泡剂和水，高抗渗水泥基修复材料具有抗折和抗压强度高、粘结强度高、抗渗等级高和抗渗压力大、干缩率低和耐久性等优势；可解决隧道工程中隧道衬砌混凝土自防水性能差的问题，亦可修复已遭渗漏水侵蚀劣化的隧道衬砌结构，解决隧道渗漏水问题，不仅解决传统衬砌混凝土不够密实、收缩开裂或温度荷载应力开裂等造成自防水能力差的问题，亦可对已劣化的传统衬砌混凝土进行及时修补维护，解决隧道工程渗漏水问题。
