Construction method for waterproof renovation of railway concrete roof
The invention relates to the technical field of concrete roof waterproofing, and particularly relates to a construction method for waterproof renovation of a railway concrete roof. The construction method comprises the steps that an old waterproof layer is removed; a waterborne base coat is brushed or sprayed on the cleaned concrete base surface, after the surface is dried, a liquid coiled material is brushed on detail joints firstly, then non-woven fabric is laid and pasted, then the liquid coiled material is brushed, and after the surface is dried, the liquid coiled material is sprayed on the whole concrete base surface; and a quick-setting waterproof coating is sprayed on the dried liquid coiled material, and a high-elasticity weather-proof waterproof layer can be formed after drying. Through interaction among a sand consolidation base coat, the waterborne base coat, the liquid coiled material and the sprayed quick-setting waterproof coating, the problem of waterproof renovation of the railway concrete roof is thoroughly solved, the aging-resistant age limit of the roof is prolonged, the service life of the roof is prolonged, and the maintenance cost is reduced.
本发明涉及混凝土屋面防水的技术领域，尤其涉及一种铁路混凝土屋面防水翻新的施工方法。本发明通过清除旧的防水层；在清理后的混凝土基面涂刷或喷涂水性底涂，待表干后在细部节点先涂刷液体卷材，然后铺贴无纺布，然后再涂刷液体卷材，表干结束后再对混凝土基面整体喷涂一道液体卷材；在干燥后的液体卷材上喷涂速凝防水涂料，干燥后即可形成高弹耐候的防水层。通过固砂底涂、水性底涂、液体卷材以及喷涂速凝防水涂料之间的相互作用，彻底解决了铁路混凝土屋面防水翻新的难题，增加了屋面的耐老化年限和使用寿命，降低了维护成本。
