在罗德兹(Rodez)城附近,正在修建一座蓄能电站水库,该项工程是法国供电网发展计划的一部分。为消除早上几小时的峰值负荷,需在41%的斜坡上修建两座输水隧道,全长530米,浇筑混凝土。承包公司决定采用皮兹梅斯泰(Putzmeister)附有5米~3大型槽固定式混凝土泵来浇筑混凝土。混凝土从设置在隧道入口的中心站借助一台再拌合器输送到约1公里的山里。混凝土通过大槽中的螺旋输送器填进输送泵中,然后通过一导管泵入压力井中。受“大象鼻子管”控制的最后总高度为360米。已经达到的高度为300米,总输送距离428米,泵的压力120巴。总的运量大约可浇筑12米~3/小时。在圣
Near Rodez, a reservoir for energy storage is being built as part of a French power grid development plan. In order to eliminate the peak load in the morning hours, two water-supply tunnels are to be constructed on 41% of the slopes, measuring 530 meters in length and pouring concrete. The contractor decided to use Putzmeister with 5 to 3 large tank-mounted concrete pumps for concrete placement. Concrete is transported from a central station located at the tunnel entrance to a mountain about 1 km by means of a re-mixer. Concrete is filled into the transfer pump through the screw conveyor in the large tank and then pumped into the pressure well via a conduit. The final total height controlled by “Elephant Nose Tube ” is 360 meters. The height reached has been 300 meters with a total conveying distance of 428 meters and the pressure of the pump is 120 bar. The total capacity of about 12 meters to pouring 3 / hour. In the holy
