摘要
吉林台一级水电站因工期原因,深孔泄洪洞进水塔1349～1356m高程混凝土及导流洞永久堵头混凝土施工必须在冬季进行。深孔泄洪洞进水塔等部位的混凝土浇筑采用了暖棚法,经计算表明,该方法满足施工要求。此外,混凝土浇筑还采取了一系列的温控及养护措施,这些经验可为类似工程提供参考。
Because of restriction of the construction period in Jilintai- Ⅰ Hydropower Station, the concrete for the low level power intake tower between elevation 1349m and 1356m and the permanent concrete plug for the diversion tunnel had to be placed in the winter season. Therefore, warm enclosure method was applied for concrete pours at low level power intake tower and low level spillways. It was indicated by calculations that the placing method meets the construction requirements. In addition, a series of temperature control and curing measures were taken during the concrete placement. All these experiences may provide information useful to similar projects.
