摘要
两河水电站大坝心墙土料冬季填筑施工采用“三布两膜”进行土料覆盖保温。为保证心墙施工快速流水作业,利用液压挖掘机的正铲油压系统,实现液压马达的正反旋转,解决旋转速度的调速问题,并研制出了土工膜快速收放机,完成“三布两膜”的快速收放作业,极大地提高了收放效率,有效地避免了人工收放作业的弊端,减少了施工成本,具有较广泛的适用性和经济性。
“Three-cloth two-membrane” is adopted to cover soil and keep warm for winter filling construction of dam core walls in Lianghe Hydropower Station. The face shovel hydraulic system of the hydraulic excavator is utilized in order to ensure the fast flow operation of core wall construction, thereby realizing positive and negative rotation of the hydraulic motor, solving the problem of regulating the rotation speed. The fast-retracting machine of the geomembrane is developed, thereby completing the fast-retracting operation of “three-cloth two-membrane”, greatly improving the reacting efficiency, effectively avoiding the disadvantages of artificial retracting operations, and reducing the construction cost. It has wide applicability and economical efficiency.
