Background
Concrete curing is an artificial condition of humidity and temperature that allows the freshly poured concrete to set normally or accelerate its hardening and strength development. The concrete can harden and increase strength gradually as a result of the hydration of the cement, which requires certain temperature and humidity conditions. If the surrounding environment does not exist under the condition, the concrete needs to be manually cured.
In construction engineering, concrete curing is a very important task, which has a crucial influence on the strength of concrete. The curing can well promote the hydration reaction of cement in the concrete, so that the concrete is in an optimal humidity environment, the strength of the formed concrete is ensured, and meanwhile, the adverse conditions such as cracking and the like of the concrete are avoided.
The concrete curing generally adopts a plurality of methods such as natural curing by sprinkling, curing by spraying curing liquid, curing by covering plastic film and the like. The concrete curing mechanisms are to keep the concrete moist and avoid water loss so as to achieve the curing purpose. Wherein water spraying maintenance is the most common mode; the spraying curing liquid curing method has the advantages that the curing liquid is expensive, and the curing cost is too high; the covering plastic film wrapping maintenance is often suitable for the maintenance of large-area horizontal components. Steam curing may also be used for some pre-stressed or small movable components, which may be more costly to cure.
In the maintenance of the concrete retaining wall, because the concrete retaining wall is a narrow and long vertical component which is nearly vertical, a method of covering plastic films for heat preservation and moisture preservation cannot be adopted. The maintenance cost of the maintenance liquid is too high, water can flow away quickly by adopting the sprinkling of the conventional method, a large amount of water is lost, and the repeated sprinkling of the water is required by personnel, so that the construction efficiency is low, and the manual maintenance work effect is uncontrollable. The retaining wall is outdoor, air flows fast, the evaporation capacity is large, and particularly in summer, the retaining wall still needs to be maintained in time at night, and reliability is not easy to guarantee by means of manual watering.
In the prior art, when the power supply device is adopted in maintenance, electric leakage is easily caused when a temporary electric wire is pulled and arranged, so that a series of safety problems are caused, a conventional maintenance device is difficult to well carry out mobile installation according to construction progress of retaining walls in different areas, quality reduction caused by untimely manual maintenance easily occurs in the maintenance construction process, manual sprinkling is large in water consumption, and meanwhile, more manpower expenditure is required for whole construction.
