Study On Technology Of Construction In Winter For Concrete Bridge

During of the construction time of large bridge is long, concrete is made all the year round. To shorten the construction time, study on technology of construction in winter for concrete bridge must be carried on.On based of the capability of concrete and characteristics of construction in winter, the influence of climate in winter on new mixed and hardened concrete is analyzed. The critical intensity of concrete allowing breezed early is confirmed, and estimating formula of mature degree of concrete are put forwarded.From Aspects of concrete construction methods, construction organizing, quality control, construction project optimizing, study on technology of construction in winter for concrete bridge is carried on, heat equilibrium theory of construction in winter for concrete bridge is summed up.The measure of construction in winter for concrete bridge is taken properly, quality of construction is assured, and effect is good.
