Old concrete repairing and reinforcing construction method
The invention provides a construction method for heightening an anti-seepage geomembrane for a soil dam. The construction method comprises the following steps that the to-be-repaired surface of a concrete building is swept, all sundries are removed, and the to-be-repaired surface is polished to be flat; a carbon fiber plate consistent with the to-be-repaired surface of the concrete building in shape and size is obtained through cutting firstly, and then an epoxy resin adhesive is smeared to adhere the carbon fiber plate to the to-be-repaired surface of the concrete building; and after standing is conducted for at least 24h, the epoxy resin adhesive is cured. By adoption of the technical scheme, various sundries on the to-be-repaired surface of the concrete building are thoroughly removed, a mortar cushion layer and the epoxy resin adhesive can make full contact with the carbon fiber plate, the situation that the mortar cushion layer and the epoxy resin adhesive contain impurities and bubbles is avoided, the carbon fiber plate is fully filled with the epoxy resin adhesive, the bonding quality, the bonding effect and the bonding strength are guaranteed, and the construction quality is improved.
本发明提供一种土坝加高防渗土工膜施工方法，包括以下步骤：对混凝土建筑物待修复表面进行清扫，清除所有杂物并打磨平整；先切割获得与混凝土建筑物待修复表面形状、大小一致的碳纤维板，再涂抹环氧树脂粘合剂将该碳纤维板粘附在混凝土建筑物待修复表面上；静待至少24h以后，使环氧树脂粘合剂固化。采用本发明的技术方案，彻底去除了混凝土建筑物待修复表面上的各种杂物，使砂浆垫层、环氧树脂粘合剂能够与碳纤维板充分接触，避免砂浆垫层、环氧树脂粘合剂中含有杂质和气泡，使环氧树脂粘合剂充分填入碳纤维板内部，保证了粘接质量、粘接效果和粘接强度，保证了粘接质量、粘接效果和粘接强度，提升了施工质量。
