The invention provides a winter construction process of large dock wall concrete in severe cold areas. The process comprises the following steps of firstly, excavating a foundation pit and then constructing a cast-in-place pile; afterwards, pouring buttress concrete twice and backfilling an excavated area layer by layer; and finally constructing a gallery, wherein the key point of winter construction of the large dock wall concrete is concrete supply, and a mixing plant production line for preparing the concrete is totally closed and insulated. The mixing plant production line is totally closed and insulated, so that the required material consumption is less while mass production of the concrete in winter is ensured, the concrete quality can be effectively guaranteed, and the discharge temperature can be controlled.
本发明提供了一种严寒地区大型坞墙混凝土冬季施工工艺,包括:先基坑开挖再灌注桩施工,接下来分两次浇筑扶壁混凝土,随后分层回填开挖区域,最后进行廊道施工;其中:大型坞墙混凝土冬季施工的重点是混凝土供应,用于制备混凝土的搅拌站生产线全封闭保温。本发明的搅拌站生产线全封闭保温,确保混凝土在冬季大规模生产的同时使所需材料用量较少,能有效保障混凝土质量、控制出机温度。
