摘　要: 兰州市水源地建设工程工期短、任务重,不可避免的要在冬季进行程施工。根据SL352-2006《水工混凝土试验规程》日平均气温连续5天稳定在5℃以下或最低气温连续5天在-3℃以下时,按低温季节施工。根据兰州气象站资料记录,本工程区属典型的大陆性气候。冬季受蒙古高压的控制,天气干冷晴朗,常有寒潮侵入,1月~2月为全年最冷季节,一月份平均气温最低,为-5.3℃。这已经超过了冬季施工的平均最低温度,所以要进行混凝土的保温工作。

Abstract: Lanzhou City water project construction period is short,heavy task,inevitable to engineering construction in winter,according to SL352- 2006 the hydraulic concrete experiment regulations "daily average temperature continuous stable for 5 days in 5 DEG C or minimum temperature for 5 consecutive days below 3 DEG C,according to the construction in low temperature season. According to the Lanzhou meteorological station data series,continental climate are typical of this project. In winter by the Mongolian high pressure control,the dry and cold weather is sunny,often cold invasion,January to February is the coldest season of the year,the average temperature in January lowest 5. 3℃.This has exceeded the average minimum temperature in the winter construction,so the thermal insulation work to be carried out.
Keywords: Lanzhou water source construction engineering concrete winter low temperature heat preservation
