南阳回龙抽水蓄能电站碾压混凝土重力坝施工

Construction of Rolling Concrete Gravity Dam of Nanyang Huilong Pumped Storage Power Station

南阳回龙抽水蓄能电站上库碾压混凝土重力坝,由于受地形等自然条件影响,入仓方式和拌和能力等受到限制,在本工程中采用了坝前入仓,且在碾压混凝土施工中采用斜层平推法施工,较好地解决了入仓和碾压混凝土施工问题,而且在碾压混凝土施工中加强了施工工艺控制,从成本和质量上都取得了很好的效果。

The rolling concrete gravity dam of the upper reservoir of Nanyang Huilong Pumped Storage Station, because of the effect of natural conditions like landform, is restricted in the way of placement and mixing ability. In the project, placement in front of dam is adopted and flat push of inclined layer is used in the construction ot rolling concrete, so that some problems have been properly solved, the control of construction technique has been reinforced and good results have been achieved in the control of cost and quality.
