沈阳东部净水厂施工方案
工程概况
因本工程原先铺设玻璃夹砂排水管道设计中没有考虑排气因素,管道自2０10年１1月投入使用后,在一个多月时间内先后发生了7次爆管,每次抢修都投入大量人力和物力,据统计,平均抢修一次需２台挖机工作６个台班,投入12个人工,7次抢修共重新购买管材8０．5米,鉴于此种情况,业主决定重新铺设DN600排水管道,向排水口方向看,该新铺管道相对于原DＮ６0０玻璃夹砂排水管位于DN2200源水管道右侧，与源水管道平行铺设，新铺设排水管道位置与原铺排水管道以DN220０源水管道为中心线相对称,新铺设管道材质为PE管, ，出水厂排水泵房后斜穿过10米宽村村通油路,在1150米处向下穿过约31．5米宽、。途中还需通过１40米长架
