沉管隧道管段結(jié)構(gòu)防水關系到隧道后期運營及使用壽命,一旦滲漏,修復難度非常大。以南昌紅谷隧道為例,采用＂防水底鋼板＋頂板、側(cè)墻噴涂聚合物水泥防水涂層＂的外包防水施工技術(shù)：防水底鋼板采用6 mm厚帶錨筋鋼板,能夠減小管底吸附力,保證管段順利起浮;頂板、側(cè)墻選用兼有有機和無機防水涂料優(yōu)點的聚合物水泥防水涂層,采用＂一布四涂＂大面積機械噴涂施工工藝,工效快、成本低、質(zhì)量好。通過錯縫焊接底鋼板、改善錨筋錨固形式、薄弱部位強化處理、加強試驗檢測等施工方法和技術(shù)措施,有效改善外包防水施工質(zhì)量,降低管段滲漏水風險,為今后沉管隧道外包防水設計及施工提供參考。
