6月6日,海蓄电站一级斜井下弯段衬砌混凝土全部浇筑完成。一级斜井下弯段连接引水中平洞、一级斜井直线段,桩号为引0+279.810至引0+308.008,总长28.198m,衬砌混凝土厚度为0.50m,衬砌后直径为8.40m,混凝土强度等级C30W10F100。自2017年4月18日一级斜井下弯段衬砌混凝土开始备仓施工以来,一级斜井下弯段、引水中平洞施工受上下斜井隔离平台封闭影响,空气流通困难,空气质量差,环境温度高,下
June 6, the first stage of the sea power station inclined shaft lining all the pouring of concrete pouring completed. In the first grade, the lower bend is connected with the middle hole in the diversion tunnel and the straight section in the first grade. The pile number is 0 + 279.810 to 0 + 308.008 and the total length is 28.198m. The thickness of the lining concrete is 0.50m, the diameter of lining is 8.40m, Concrete strength grade C30W10F100. Since April 18, 2017, when the lining concrete at the first grade of downcomer has been prepared for warehousing, the downcomer at the first grade of inclined shaft and the construction of the PingPin water diversion tunnel are affected by the closure of upper and lower inclined shaft isolation platforms, the air circulation is difficult, the air quality is poor, Ambient temperature, under
