以聚乙烯管材(以下简称PE管)作为浇筑大体积混凝土冷却水管,国内自二滩及三峡水利枢纽后才在水工大体积混凝土浇筑中得到普遍使用,但在交通水运浇筑大体积混凝土工程中鲜有使用。本工程在保证靠船墩承台大体积混凝土温控目标实现的前提下,大胆以PE管材替代传统使用的冷却材料——黑铁管,在加快施工进度、优化施工工艺、节约工程费用等方面,进行了大胆的尝试,并取得了预定的效果。 Polyethylene pipe (hereinafter referred to as PE pipe) is used as pouring mass concrete cooling water pipe. Since domestic Ertan and Three Gorges hydro-project, it has been widely used in large-volume hydraulic concrete pouring. However, Used. Under the premise of guaranteeing the temperature control of mass concrete in piers pier, the project boldly replaces the traditional use of cooling material - black iron pipe with PE pipe to speed up construction progress, optimize construction technology and save construction cost. A bold attempt was made and the results achieved.
