Urban underground inspection well inner wall repairing material and construction method
The invention relates to a repairing material for the inner wall of an urban underground inspection well. The repairing material comprises a strong concrete layer and an impermeable film layer. The strong concrete layer is made of modified Portland cement, and the modified Portland cement is prepared from a Portland cement component, a slag component and a siliceous slag component according to the mass fraction ratio of (75-80): (20-10): (5-10); the impermeable film layer is prepared from unsaturated epoxy resin, tert-butyl ester (catalyst) and PX16 (curing agent) according to the mass fraction ratio of (90-110): (0.8-1.2): (0.7-0.9); and the inner wall is sprayed by adopting a CCM inspection well centrifugal spraying technology. The strong concrete layer is attached to the outer side of the original inspection well bricking layer. The impermeable film layer is attached to the outer side of the strong concrete layer. The characteristics of the two different materials are integrated, and the obtained repairing material has the advantages of ultrahigh strength, wear resistance, strength, corrosion resistance and good anti-seepage performance, and can be used for quickly repairing the diseases such as corrosion, cracks, leakage, plaster falling, launder damage and the like of the inner wall of the inspection well.
本发明是一种城市地下检查井内壁修复材料，所述修复材料包括：强混凝土层和防渗膜层。所述强混凝土层为改性硅酸盐水泥，所述改性硅酸盐水泥成分按硅酸盐水泥组分：矿渣组分：硅质渣组分质量分数比75～80∶20～10∶5～10进行配制；所述防渗膜层成分按不饱和环氧树脂、叔丁脂(催化剂)、PX16(固化剂)三组分质量分数比90～110∶0.8～1.2∶0.7～0.9进行配制；并采用CCM检查井离心喷涂技术进行内壁喷涂。所述强混凝土层与原有检查井砌砖层外侧贴合。所述防渗膜层与强混凝土层外侧贴合。本发明综合了两种不同材料的特性，所得修复材料具有超高强度、耐磨、强力、抗腐蚀性以及防渗性能好，对检查井内壁腐蚀、裂缝、渗漏、抹面脱落、流槽破损等病害进行快速修复。
