Description

TECHNICAL FIELD

[0001] The utility model relates to the field of concrete maintenance, especially to a mass concrete maintenance device. BACKGROUND

[0002] Nowadays, mass concrete is widely used in large civil engineering. After pouring, a large amount of heat is generated due to the hydration of cement inside the mass concrete. The heat inside the concrete is not easy to dissipate, causing the internal temperature of the concrete to rise, while the heat on the surface of the concrete is easy to dissipate, resulting in a large temperature difference between the inside and outside of the mass concrete, which is prone to temperature deformation and cracks on the concrete. When maintaining mass concrete, insulation materials are usually used to cover the surface of the concrete structure to prevent the internal and external temperature difference from being too large due to rapid cooling of the concrete. At the same time, water is sprayed on the surface of the concrete to reduce the evaporation of water on the surface of the concrete, keeping the surface of the concrete moist to prevent the surface of the concrete from drying out and cracking.
