Construction method for waterproof renovation of railway metal roof
The invention relates to the technical field of railway roof renovation, and particularly discloses a construction method for waterproof renovation of a railway metal roof. The construction method comprises the following steps that firstly, the railway metal roof is derusted and decontaminated (if the derusting is not thorough, a layer of rust fixing prime coat is coated), then a prime coat is coated twice, then a liquid coiled material is brushed on detail nodes by adopting a one-cloth two-coating method, the liquid coiled material is sprayed integrally after a surface is dried, then a quick-setting waterproof coating is sprayed to form a waterproof layer, and finally a finish coat is coated selectively. Waterproof renovation of the railway metal roof is realized. According to the construction method for waterproof renovation of the railway metal roof, the difficult problem of base surface treatment of the rusted metal roof is solved, the cost of base surface treatment is reduced, the construction efficiency and the waterproof effect are improved, a later coating film does not fall off or swell, and the service life is prolonged.
本发明涉及铁路屋面翻新技术领域，具体公开了一种铁路金属屋面防水翻新的施工方法。本发明先将铁路金属屋面除锈除杂(若除锈不彻底便涂覆一层固锈底涂)，再进行两次底漆涂覆，然后采用一布两涂法对细部节点涂刷液体卷材，表干后再整体喷涂一道液体卷材，随后喷涂速凝防水涂料，形成防水层，最后选择性涂覆面漆，实现对铁路金属屋面的防水翻新。本发明解决了锈蚀后的金属屋面基面处理的难题，降低了基面处理的成本，提高了施工效率和防水效果，后期涂膜不脱落，不鼓包，增加了耐久年限。
