Construction Planning, Plants and Equipment for Concrete Works at Yeywa HPP
The Yeywa Hydroelectric Project is under construction at present in Myanmar. The civil works involves approximately 2. 8 million m3 of concrete, 90％ of this volume being Roller Compacted Concrete (RCC) for the main dam. The rest are conventional mass concrete and structural reinforced concrete for the appurtenant structures: powerhouse, intake towers, surface spillway, diversion tunnels, etc. The total construction period for the dam is 35 months, thus the average RCC monthly production required is 70, 000m3/month and this makes Yeywa a challenging project at the top of the ranking list of the largest and fastest RCC dams that have been built so far. A detailed construction planning and construction methodology was outlined during the design stage. A key aspect during this planning was the selection of the type and capacity of the concrete production facilities and cooling plants. This paper describes our experience regarding the specification, layout, design, installation, commissioning and operation of the plants and equipment for the concrete works. One of the most special aspects at Yeywa Project was the implementation of high-quality automatically- controlled plants in a less technical and qualified environmental. Therefore in addition to the usual procedures, a very comprehensive programme for training the local staff and back-up support from foreign expertise has been implemented. Finally the experience in the operation of the plant since one and a half year ago has shown at Yeywa a great success of the concrete production team in terms of both quality and production.
