摘要
城市应急水源建设随着当前城镇化不断扩张而逐渐增多,针对铜鼓当前供水能力潜在不足的现状,对拟建供水水库进行了工程地质条件评估,得出需对坝基进行防渗处理的结论,结合水文资料、水文特征参数同时对城镇进行供需平衡分析,得出了拟建水库的库容规模和水库供水量。最终结合现场条件确立了混凝土重力坝并对坝基进行了固结灌浆处理,在大坝左侧上游设置取水口,采用塔式分层取水。
The construction of urban emergency water sources is gradually increasing with the continuous expansion of urbanization.In response to the current situation of potential insufficient water supply capacity in Tonggu,this paper evaluates the engineering geological conditions of the proposed water supply reservoir and concludes that anti-seepage treatment is necessary for the dam foundation.By combining hydrological data and characteristic parameters,the supply-demand balance analysis of the town is conducted to determine the capacity scale and water supply of the proposed reservoir.Finally,combined with the site conditions,the concrete Gravity dam is established and the dam foundation was treated with consolidation grouting.The water intake is set at the upstream on the left side of the dam,and the tower type stratified water intake is adopted.
