Waterproof system structure for repairing waterproof layer of bridge deck of ballastless track railway and construction method of waterproof system structure
The invention relates to a waterproof system structure for repairing a waterproof layer of a ballastless track railway bridge floor and a construction method of the waterproof system structure, the waterproof system structure comprises a bridge floor concrete base layer, a waterproof bottom coating arranged above the bridge floor concrete base layer and a waterproof surface coating coated on the waterproof bottom coating, the waterproof bottom coating is a two-component polyurethane coating, and the waterproof surface coating is an aliphatic polyurethane coating. According to the waterproof system structure, a traditional waterproof layer and a surface coating are combined into a whole, the high physical and mechanical properties of the traditional waterproof layer and the high weather resistance and aging resistance of the surface coating are integrated, and the requirements of the waterproof standard or technical condition of the concrete bridge deck of the ballastless track railway in China are met.
本发明涉及一种无砟轨道铁路桥面防水层修复用防水体系构造及其施工方法，防水体系构造包括桥面混凝土基层、设置在桥面混凝土基层上方的防水底涂层以及涂覆在防水底涂层上的防水面涂层，所述防水底涂层为双组份聚氨酯涂料，防水面涂层为脂肪族聚氨酯涂料。本发明的防水体系构造，将传统的防水层和面涂层合二为一，兼具了传统防水层的高物理力学性能以及面涂层的高耐候性能和耐老化性能，满足我国无砟轨道铁路混凝土桥面防水的标准或技术条件的要求。
