The loading device is arranged in the container for being contained with seawater, and seawater lid crosses the 3rd group of top of concrete sample
Face.
In order to accurately easily install test specimen, instruction line is carved with according to sample dimensions on pressure diaphragm and base plate.
Further, since needing loading device to be integrally immersed in infiltration apparatus, it is necessary to consider seawater for loading device
The corrosion function of itself, it is therefore desirable in the anti-acid etching coating of each parts surface brushing of loading device, and inspect periodically it and receive
Erosion degree, so as to ensure the service life of device.Further, since under natural environment, due to the evaporation meeting of moisture in solution
Cause solution concentration to raise, produce influence on experiment, thus on the inwall of container, be carved with indicating graduation on depression bar, test people
Member should regularly check whether liquid level of solution is maintained at indicating graduation in practical operation, so as to ensure that solution concentration is constant.
During actual loaded, it is first according to design and has installed test specimen additional, then using four-point bending spring charging device
Long term constant loading corrosion test is carried out to test specimen.Hydraulic jack is used lentamente to be applied to top board with balancing speed during loading
Plus stress is until regulation stress ratio, then rapid tightening nuts.Existed by three groups of test specimen foil gauges during loading is kept
The numerical value shown on stressometer is regularly monitored, so that proof stress size is maintained at setting.
Compared with prior art, the beneficial effects of the utility model are：
The utility model can not only meet the resistance to compression loading to concrete sample under briny environment, and concrete can be tried
The compression situation of part carries out monitor in real time, reduces experimental error.
