水電站下游圍堰堰基防滲工程施工組織設計

水電站下游圍堰堰基防滲工程施工組織設計 xx電站下游圍堰設計堰頂高程為1012.00m，圍堰填筑材料主要為土石料，高程下游圍堰地段出露的巖層為MⅣ-1：黑云花崗片麻巖夾片巖，另外在下游側堰腳部及江中有人工堆積層（Qs主要由含孤石的塊石、碎石質粉土組成，稍密～中密，孤沿帷幕灌漿軸線方向，澆筑混凝土施工蓋板，混凝土蓋板平均厚度不小于0.4m，根據(jù)本次施工的投入設備情況（參見主要施工機械設備表施工主要設備總功率變壓器設備由甲方負責提供和安裝在下游圍堰左堰肩部位，變壓器以下的低壓部在施工工作平臺的下游側（施工平臺和水泥制漿站之間全長修建排污溝，斷面孔123456789圍堰合攏后，堰基防滲施工工作全面展開將于xx年11月5日左右開始進行。xx的生產(chǎn)工效，按照全線開工日期進行安全計算，此次施工需要投入14個施工機組。計644112622SGZ-Ⅲ642246”21114243221
