Grouting material for hydraulic engineering construction and grouting method thereof
The invention relates to the field of water conservancy projects, in particular to a grouting material for water conservancy project construction and a grouting method thereof, and provides a grouting material which is high in underwater bonding strength with concrete, high in bonding impermeability grade, low in elastic modulus, low in body shrinkage rate, high in crack deformation resistance, high in impact toughness and good in water conservancy project construction performance. The polyester fiber, the curing agent and the water-based acrylate emulsion are added into the raw materials to ensure the curing effect of grouting, and in addition, the grouting material is simple in process operation, easy to store, stable in performance and suitable for popularization and application. The water plugging and seepage-proofing agent can be widely applied to short-term water plugging and seepage-proofing projects in the geotechnical engineering fields of water conservancy, hydropower, mines, tunnels, underground spaces and the like.
本发明涉及水利工程领域，具体的涉及一种水利工程施工用灌浆材料及其灌浆方法，本发明提供一种与混凝土水下粘结强度高，粘结抗渗等级高，弹性模量低，本体收缩率低，抗裂缝变形能力强，抗冲击韧性高，耐环境腐蚀能力强的水利工程施工用灌浆材料通过在原料中添加了聚酯纤维、固化剂和水性丙烯酸酯乳液来保证灌浆的固化效果，另外本发明工艺操作简单、易于存放、性能稳定，可广泛应用于水利、水电、矿山、隧道、地下空间等岩土工程领域的短期性的堵水、防渗工程。
