Background technology
Concrete in mass is mainly used in the important engineerings such as power station, nuclear power station, hole culvert, bridge, and its bulky (side up to a hundred at least can reach tens sides at most), quality requirement is very strict.At present, for the detection of concrete in mass performance, carry out test room simultaneously and detect concrete sample, the maintenance in early stage of test specimen sets to be carried out at a constant temperature.Regulation in " concrete for hydraulic structure testing regulation " (SL352-2006), the standard curing temperature of test specimen should control at 20 DEG C ± 5 DEG C; Patented technology is even had to provide a kind of concrete specimen curing box, for realizing the curing temperature of concrete sample, humid control under the condition of relative constancy.
But the check data that said method can produce test room usually differs larger problem with Site Detection data.Because job site affects by environment and concrete in mass self-heat generation, mass concrete temperature is not aquation and solidification under isoperibol, but under environment temperature and self-heat generation acting in conjunction along uniform temperature curve in regular change.Therefore, carrying out maintenance by stationary temperature condition to test specimen is produce test room's check data to differ larger main cause with Site Detection data, by the prediction of impact as the concrete in mass performance of these important engineerings such as power station, nuclear power station.
Because of its bulky of concrete construction during site operation, in cement hydration process, the huge heat of generation is stayed inside concrete and be not easy release, often produce thermal stress cracks because internal temperature (generally no more than 70 DEG C) and surface temperature difference (temperature difference is generally no more than 25 DEG C) are excessive, and distress in concrete have a direct impact concrete impermeability and integral rigidity, will shorten greatly concrete application life so that harm total safety.The maintenance of concrete surface not only can affect concrete sclerosis and then affect concrete quality, maintenance is improper also can cause surperficial dehydration or temperature is improper causes crack, can therefore after concreting, maintenance construction be very crucial, be directly connected to its structure and meet normal safe use.
At present, empirically manually watering maintenance is carried out for the concrete curing mainly constructor that constructs, or inner and hull-skin temperature situation of change judges whether to need to carry out maintenance work by some simple testing arrangement manual testings.This kind of mode whole process needs artificial supervision, and the course of work is loaded down with trivial details, and maintenance quality cannot ensure, careless slightlyly just may cause concrete cracking.
Utility model content
The purpose of this utility model judges moisturizing problem for the artificial experience that relies on main in current Mass Concrete, and the problem of supplementary water time and rate of water make-up control accuracy difference, provide a kind of and be applicable to moisturizing accuracy-control system in Mass Concrete.
The technical solution of the utility model: a kind of concrete in mass Humidity Detection and moisturizing control system, constructing, concrete surface layer arranges humidity sensor, humidity sensor is connected with the controller signals input of spray dampening system by delayer A, the controller output end of spray dampening system is connected with water pump, arranges delayer B or flow meter on water pump simultaneously.
Be provided with temperature pick up together with humidity sensor simultaneously, and cooling coil is set in concrete in mass, temperature pick up is connected with the controller signals input of cooling system, and the controller output end of cooling system connects coolant pump, and coolant pump delivery outlet is communicated with cooling coil.
Spray dampening system is provided with and is uniformly distributed in the plane shower nozzle of concrete surface for spraying towards periphery, and is arranged on the three-dimensional shower nozzle of concrete vertical face; Each shower nozzle is communicated with water spray house steward by arm; Or spray dampening system arranges water cannon at concrete periphery.
