Concrete maintenance device

Abstract

The invention relates to the technical field of concrete manufacturing, and specifically relates to a concrete maintenance device comprising a water catchment layer, a foam plastic layer and a linen layer. The water catchment layer is a plastic film bag with water-permeable holes opened in its bottom. The plastic film bag is arranged above the foam plastic layer. The foam plastic layer is arranged above the linen layer. The peripheries of the water catchment layer, the foam plastic layer and the linen layer are connected head-to-tail and sealed by limiting plates. The plastic film bag is connected with a water pipe; and the water pipe is communicated with a water tank through a water pump. The concrete maintenance device is simple in structure; the arrangement of the water catchment layer can ensure the foam plastic layer to be always in a wet state; the foam plastic layer provides a water source having enough water to the linen layer, thereby allowing the linen layer to completely absorb water for conveniently implementing heat preservation and wet preservation operations to the concrete. The concrete maintenance device is convenient to use, is water-saving and labor-saving, and is able to keep the humidity and the substantially constant temperature of the concrete maintenance surface, accordingly ensuring the concrete maintenance quality as much as possible.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a concrete maintenance device. Background technique [0002] In order to obtain good concrete quality, after the concrete is formed, it must be cured to ensure the normal progress of the cement hydration process. Through a large number of on-site observations of concrete, it is found that maintaining the humidity of the concrete surface becomes the most critical factor for concrete curing when the temperature is appropriate. At the concrete construction site, the traditional concrete curing method usually adopts the method of covering the concrete surface with grass (hemp) bags and watering, because this method fails to isolate the grass (hemp) bags and the concrete surface from the outside air, so the curing effect Strongly affected by the dry air, especially in summer, the strong sunlight makes the water evaporate quickly. To ensure the maintenance quality of the c...

At the concrete construction site, the traditional concrete curing method usually adopts the method of covering the concrete surface with grass (hemp) bags and watering, because this method fails to isolate the grass (hemp) bags and the concrete surface from the outside air, so the curing effect Strongly affected by the dry air, especially in summer, the strong sunlight makes the water evaporate quickly. To ensure the maintenance quality of the concrete, it must be watered continuously, so the water consumption is large and the labor intensity is high; at the same time, there are grasses. (Hemp) bags are easy to rot, short life, pollute the concrete surface and the environment, etc.
