Temperature Stress Control of Mass Concrete Pouring in Water Transmission Pipeline Engineering
In order to explore effective measures and implementation effects for temperature stress control of mass concrete pouring suitable for support pier structure of water transmission pipe line,taking a water transmission pipeline project in Xinjiang as an example,the concrete pouring temperature and temperature stress of the buttress pier were calculated.Based on the calculation results,the temperature stress control measures were analyzed from the aspects of raw material control,concrete mold temperature control,cooling water pipe layout,and covering insulation.The results indicate that temperature stress control during mass concrete pouring is a key and difficult point in quality control of similar engineering construction.It is necessary to take effective measures to strengthen temperature control and prevent the occurrence of temperature shrinkage cracks in combination with engineering practice.
