Abstract

The invention discloses a high and cold region low-temperature season concrete construction method, and relates to the technical field of concrete construction. By means of a specially-made electrothermal template, heating is conducted when concrete pouring is conducted, heating copper wires are uniformly distributed in the electrothermal template, temperature sensors and heating rods are arrangedon the side face, facing concrete, of the template, the heating copper wires wind around the heating rods, a heat conducting shell is arranged outside each heating rod, the heating rods are vertically inserted into the concrete, and the concrete is heated; the temperature sensors are arranged every 1-2 m<2>, and the heating rods are arranged every 0.04-0.1 m<2>; the inner side of the electrothermal template and the surface of the heat conducting shell are coated with waterproof paint. The high and cold region low-temperature season concrete construction problem can be solved, and the concreteengineering construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a concrete construction method in low-temperature seasons in alpine regions. Background technique [0002] At low temperature, the hydration of cement is weakened, and the concrete hardens very slowly, thus affecting the strength of concrete. If the temperature drops below 4°C, the water required for cement hydration begins to expand, possibly causing permanent damage to the fragile, newly formed cement particle structure. If the temperature of concrete drops below the freezing point, since the frozen water cannot combine with cement, the new compounds produced by the chemical reaction in the concrete will be greatly reduced, which will cause the loss of concrete strength and durability. If the temperature difference of the concrete member itself is very large, temperature cracks will also appear. Construction in alpine regions, especially in low-temperature seaso...
