運用新材料快速處置橋梁伸縮縫

日期:2013-08-05 16:51 關注:
錫山區東廊路潘墅河橋的橋頭上機聲轟鳴, 錫山區公路管理處正安排維護人員運用新材料、新工藝對損壞的橋梁伸縮縫進行修正。其間,市公路處的領導和技術人員親臨現場進行輔導。

  這次橋梁伸縮縫修正依照切開路面-鑿除碎石-鋼筋骨架焊接-澆筑混凝土-震搗密實-抹平收光等工藝流程進行。值得一提的是,這次澆筑中運用的是新材料—“超快硬混凝土修正王”,其初凝時刻僅為15分鐘,攝生時刻為1小時,強度即可達30至40兆帕,這也意味著橋面從混凝土澆筑到敞開通行只需1個多小時,而選用傳統的混凝土澆筑其攝生時刻最快也要3天。新材料的推行運用,其優勢在于現場操作簡潔,交通敞開疾速,既提高了功率,又減少了對交通的影響,具有較強的現實意義。
