Description

Technical Field

[0001] The invention belongs to the technical field of spraying maintenance systems, and in particular relates to an intelligent spraying maintenance system for segmental box beams. Background Art

[0002] The prefabrication of segmental box beams uses C50 high-performance concrete. After the concrete is poured, it can gradually solidify and harden mainly because of the hydration of the concrete. The hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength is continuously enhanced, the concrete must be sprayed and cured. After the concrete is poured, if the climate is hot and the air is dry, if the spraying and curing is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be converted into stable crystals, lacking sufficient bonding force, and thus causing flakes or powders to fall off on the surface of the concrete. In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also produce large shrinkage deformation and shrinkage cracks, affecting the durability and integrity of the concrete. Therefore, the initial stage of concrete curing after pouring is very important, and the concrete should be cured immediately after final setting.
