| description | The invention discloses a segment winter pouring process, and belongs to the technical field of tunnel segment production and manufacturing. According to the segment winter pouring process, portland cement is adopted to be made into semi-flowing concrete, and aggregate does not contain ice cubes and frozen agglomerates; the concrete stirring time is prolonged by 30 s, stirring is conducted with hot water, and it is guaranteed that the temperature of the concrete placing into a mold is higher than 10 DEG C; and concrete is poured through a numerical control distributing machine. The portland cement is adopted to be made into the semi-flowing concrete, so that the quality of segments manufactured in winter is improved, and the shear resistance of the segments is improved. When the segment winter pouring process is in use, the concrete can have the good properties of salt ion corrosion resistance, freeze-thaw cycle damage resistance, high permeation resistance and the like.
