鸳鸯桥水电站大坝混凝土入仓方案分析

Analysis of concrete placing scheme for main dam construction of Yuan-yang-qiao Hydropower Project

结合鸳鸯桥水电站大坝工程特点,选取3个混凝土入仓施工方案,从经济性、工期进度、安全性和可操作性上进行比选,并进行了优化和改进,最终采用优化后的方案三:利用有利地形落差,用溜槽将自拌料从550平台送到537平台,租用一台混凝土泵设备,直接将料泵送入仓。实施后,效果好,效益显著。

Combined with the main dam characteristics of Yuan-yang-qiao Hydropower Project, three concrete placing schemes were compared in respects of cost, construction period, safety and construction operability, based on which optimization was conducted. According to the selected scheme No.3, mixing materials are transported from platform No.550 to platform No.537 with chute system taking advantage of terrain drop, then are directly pumped into place. Execution of selected scheme has rendered favorable effects and henefits.
