Anti-skid method for ultra-high performance concrete UHPC bridge deck slab
The invention discloses an ultra-high performance concrete UHPC bridge deck slab anti-skid method, which belongs to the technical field of road safety, and is characterized in that the ultra-high performance concrete UHPC is proportioned and improved, the snow melting performance of the ultra-high performance concrete UHPC is optimized, and neutral calcium magnesium acetate is adopted to partially replace chlorine salt in the ultra-high performance concrete UHPC, so that the anti-skid performance of the ultra-high performance concrete UHPC is improved, and the anti-skid performance of the ultra-high performance concrete UHPC is improved. While the snow melting performance of the UHPC is ensured, the corrosion of chloride ions to steel bars in the UHPC is effectively relieved. For the accumulated water flow guide function of the UHPC, water left on the bridge deck slab is guided into a drainage ditch through transverse corrugations. According to the invention, various properties of the UHPC are ensured, and the problem of pavement skid resistance of large bridges and highway engineering under complex conditions of accumulated water diversion, accumulated snow melting, vehicle slippage prevention and the like on bridge decks in rainy and snowy areas is effectively solved.
本发明公开了一种超高性能混凝土UHPC桥面板防滑方法，属于道路安全技术领域，解其技术要点是：通过对于超高性能混凝土UHPC进行配比改良，针对超高性能混凝土UHPC的融雪性能进行优化，采用中性的醋酸钙镁盐部分代替超高性能混凝土UHPC中的氯盐，在保证超高性能混凝土UHPC融雪性能的同时，又有效缓解了氯离子对于超高性能混凝土UHPC中钢筋的腐蚀。对于超高性能混凝土UHPC的积水导流功能，本发明采用一种横向的波纹将残留在桥面板上的水导流到排水沟中。本发明在保证超高性能混凝土UHPC各项性能的同时，有效解决了多雨、多雪地区桥面板上积水导流、积雪消融和预防车辆滑移等复杂条件下大型桥梁、公路工程路面防滑的问题。
