| Abstract: | Tongzilin Hydropower Station locates at the area with larger temperature difference between day and night and higher temperature in summer.To prevent crack in the concrete pouring of diversion channel,the measures are undertaken during construction,including lowering hydration heat,controlling concrete temperature at the outlet of batch plant,lowering concrete temperature during placing and pouring,concrete surface curing and protection,and water cooling.No crack is found after completion. |
