冬季施工的定义:Definition of winter construction:
中国标准JGJ104-97《建筑工程冬期施工规程》中定义:日平均气温连续5天低于5℃即进入冬季施工。当室外日平均气温连续5天高于5℃时应解除冬期施工。
ACI306规定寒冷天气是指在一段时间内,通常连续超过三天,出现以下情况: 1)日平均空气温度低于40F(5摄氏度) 2) 任何一天,超过一半时间,空气温度不高于50F (10摄氏度)。
日平均空气温度是指从第一天午夜到第二天午夜之间最高温度和最低温度之间的平均值。这份报告中所提到的寒冷天气通常从秋季开始直至春季。这个时间的混凝土需采取冬期施工措施。
As defined in Chinese specification, “Specification for Winter Construction of Building Engineering”(JGJ104-97): winter construction arrives when daily average temperature is below 5℃ for five consecutive days, it ends when outdoor average temperature is above 5℃ for five consecutive days. Also, as described in ACI306, cold weather is defined as a period when, for more than 3 consecutive days, the following conditions exist: 1) the average daily air temperature is less than 40F (5℃) and 2) the air temperature is not greater than 50F (10℃) for more than one-half of any 24-hr period.
The average daily air temperature is the average of the highest and the lowest temperatures occurring during the period from midnight to midnight. Cold weather, as defined in this report, usually starts during fall and usually continues until spring. Winter concrete program shall be observed during this period.
冬季施工时间:根据气象资料,OT现场10月上旬开始平均气温低于5℃,进入3月下旬平均气温便高于5℃。所以本项目的冬季施工周期为2010年10月上旬至2011年3月下旬。
Winter construction duration: According to weather information, average temperature at OT site will be below 5℃ in early October and will be above 5℃ in later March. Therefore, the winter construction duration of this project is from early October of 2010 to later March of 2011.
冬季施工准备工作:Winter construction preparation
a) 根据施工进度计划,设备材料部门提前组织有关机具、保温供暖设备、材料的进场。
