be installed at the upstream face of the dam. In design phase, the reservoir level is designed to be controlled at the Elevation 158.24. The contractor suggested that the reservoir level shall be lower more 10 m. Then, the layout of rehabilitation is shown in Fig. 5. The shadow part will be poured by SPUC. Fig. 5 Layout of rehabiliation by SPUC of Wanyao dam Two mix of SPUC are suggested, listed in Table 1.

UPA will be diluted and casted into the water prior to the pouring of concrete same as other projects. The photo of the dam and the cast plan is shown in Fig. 6. The width of each block is 34 m and divided into 2 sub-block. 5 casting point will be set for each sub-block since the distance between two casting points is designed as 5 m. Construction of SPUC will start in the spring of 2018. Shadow part will be poured by SPUC 1181
