Railway bridge deck waterproof and drainage system and preparation and construction method of prefabricated waterproof protection layer thereof
The invention discloses a waterproof and drainage system of a railway bridge deck and a preparation and construction method of a prefabricated waterproof protective layer of the waterproof and drainage system, and relates to the technical field of railway bridge deck protection.The waterproof and drainage system comprises a waterproof layer arranged on a concrete bridge deck, and the top of the waterproof layer is connected with the prefabricated waterproof protective layer through an interface bonding layer; the top of the prefabricated waterproof protection layer is provided with a slope surface structure, and the lowest position of the top of the prefabricated waterproof protection layer is connected with a drainage pipeline. The slope surface structure of the top of the prefabricated waterproof protection layer is provided with a waterproof protection layer variable slope ridge communicating with the drainage pipeline. The prefabricated waterproof protection layer is prepared and cured under standard production conditions, drying shrinkage and cooling shrinkage of concrete can be remarkably reduced, formation of early cracks is avoided, and the uniformity, compactness and quality stability of materials are guaranteed.
本发明公开铁路桥面防排水系统及其预制防水保护层制备、施工方法，涉及铁路桥面防护技术领域，该防排水系统，包括设置于混凝土桥面板上的防水层，所述防水层顶部通过界面粘接层连接有预制防水保护层，所述预制防水保护层顶部具有坡面结构，所述预制防水保护层顶部最低位置处连接有泄水管道；所述预制防水保护层顶部的坡面结构上设有与所述泄水管道连通的防水保护层变坡棱线。本发明预制防水保护层在标准生产条件下制备和养护，可显著减小混凝土干燥收缩和降温收缩，避免早期裂缝形成，保证材料均匀性、密实度和质量稳定性。
