Winter construction scheme of hospital reinforcement project
1. When winter comes, if the outdoor daily average temperature is below 5 ℃ for five consecutive days, the first day of the five days is the first day of winter construction; When the outdoor daily average temperature is higher than 5 ℃ for five consecutive days, the last day of these five days is the end day of winter construction. 2. According to the meteorological statistics of Beijing over the years, the starting and ending time for the average daily temperature in Beijing to be lower than 5 ° C is roughly from November 15 of each year to March 15 of the next year, a total of 120 days. According to the schedule, this stage is just the main structure. Therefore, we determine that the winter construction projects of this project are earthwork, column foundation works, earthwork, reinforcement works Construction of concrete and CGM grouting material works, rebar planting works, rigid bonding and carbon fiber bonding works and other sub projects. Winter construction includes general low temperature stage and extreme low temperature stage.
