Acrylic emulsion mortar protective surface repairing construction method
The invention relates to the technical field of culvert and sluice protective surface repairing, in particular to an acrylic emulsion mortar protective surface repairing construction method which comprises the steps of raw material preparation, old concrete surface scabbling, foundation surface cleaning, mortar mixing, grid division, mortar throwing and bottoming, layered plastering and maintenance forming. The raw materials comprise cement, sand, water and a polyacrylate emulsion, and the mass ratio of the cement to the sand to the water to the polyacrylate emulsion is 1: (1-2): (0.25-0.45): (0.1-0.3); in the curing period, the temperature is controlled to be 20-35 DEG C, and the humidity is controlled to be 90% or above. According to the construction method, the cracking phenomenon of the acrylic emulsion mortar protective surface is effectively solved, the cost is reduced, meanwhile, the flood prevention strength of the sluice gate is improved, and the overall service life of the sluice gate is prolonged. The improved construction process and quality control measures have guidance for future acrylic emulsion mortar construction.
本发明涉及涵闸护面修复的技术领域，具体涉及一种丙乳砂浆护面修复施工方法，包括原材料准备、旧砼面凿毛、基础面清理、砂浆拌合、网格划分、甩浆打底、分层抹面和养护成型；原材料包括水泥、砂、水和聚丙烯酸酯类乳液，水泥、砂、水和聚丙烯酸酯类乳液的质量之比为1:1~2:0.25~0.45:0.1~0.3；养护期内的温度控制在20~35℃、湿度控制在90%以上。该施工方法有效解决了丙乳砂浆护面龟裂现象，在降低成本的同时，提高了涵闸防洪强度，延伸了涵闸整体使用寿命。改良的施工工艺及质控措施对为今后丙乳砂浆施工具有指导性。
