Steel bridge deck ultra-high performance concrete paving construction method
The invention discloses a construction method for paving ultra-high performance concrete on a steel bridge deck. The construction method comprises the following steps: S1, carrying out sand blasting derusting construction on a bridge deck steel plate; and S2, shear nails are welded on the bridge floor, and steel bars are arranged to form a steel bar net. And S3, ultra-high performance concrete paving construction is conducted on the bridge deck steel plate. And S4, after the ultra-high-performance concrete is paved, normal-temperature film covering curing is conducted firstly, then high-temperature steam curing is conducted, and an ultra-high-performance concrete layer is formed. And S5, the surface of the ultra-high performance concrete layer is subjected to sand blasting roughening, and a sticky layer is sprayed. And S6, an SMA asphalt layer is laid on the ultra-high performance concrete layer. The construction method is combined with a complete set of mechanical equipment, so that the links of manual auxiliary paving, surface repairing, film covering, moisturizing and the like are avoided, the labor intensity of workers is remarkably reduced, manpower is reduced, the construction quality is improved, and the progress of the steel bridge deck paving construction technology is promoted.
本发明公开了钢桥面超高性能混凝土铺装施工工法，包括以下步骤:S1、对桥面钢板进行喷砂除锈施工。S2、在桥面上焊接剪力钉，并布设钢筋形成钢筋网。S3、在桥面钢板上进行超高性能混凝土摊铺施工。S4、在超高性能混凝土摊铺后先进行常温覆膜养生，在进行高温蒸汽养生，形成超高性能混凝土层。S5、在超高性能混凝土层表面喷砂糙化，并喷洒沾层。S6、在超高性能混凝土层铺筑SMA沥青层。本工法结合成套机械设备避免了人工辅助摊铺、修面、盖膜、保湿等环节，显著降低了工人劳动强度，减少了人工，提升了施工质量，推动了钢桥面铺装施工技术进步。
