Description
Technical field
The present invention relates to concrete erosion detection field, especially relate to Multifunctional concrete degradation instrument.
Background technology
At present, mainly concentrate on the crystal class corrosion aspect of concrete by sulfate radical, Chloride Attack to the research of concrete corrosion resistant, test method is based on immersion type, and the instability of experimental enviroment usually brings larger negative effect to the accuracy of test findings.And, in the Decomposition Corrosion of concrete carbonate suspension, hydrocarbonate, current research is less, moreover the more difficult simulation of Decomposition Corrosion shop experiment environment, the colleges and universities scene possessing Decomposition Corrosion condition of once taking is had to carry out in-situ test, but test findings, by the restriction of field environmental condition, has narrow-mindedness.At present, for the endurance quality systematic study of concrete material at different corrosion environment (air pressure, current scour speed, temperature, Acid concentration), special experimental apparatus for testing is not also had.
Summary of the invention
The object of the invention is to provide a kind of Multifunctional concrete degradation instrument.
For achieving the above object, the present invention takes following technical proposals:
Multifunctional concrete degradation instrument of the present invention, comprises the corrosion test storehouse with gland bonnet, and described corrosion test storehouse is formed by inside and outside three layers, is followed successively by corrosion-resistant bladder layer, steel skeleton bearing stratum, stainless steel surrounding layer from the inside to the outside; Between steel skeleton bearing stratum and stainless steel surrounding layer, heat-insulation layer is set; Described corrosion test storehouse inner chamber is communicated with fluid reservoir by circulating line, variable frequency pump, flowmeter, and is communicated with aggressivity gas bomb with electric control valve by tracheae; Corrosion test storehouse inwall is provided with spray piping and multiple high-pressure atomization shower nozzles disposed thereon, and described spray piping is communicated with circulating water pool by water circulating pump; Corrosion test is provided with sewage draining exit bottom storehouse, and described sewage draining exit is communicated with dredge pump by Drainage pipe; Liquid level detecting sensor, temperature detection sensor, pH value detecting sensor is provided with in corrosion test storehouse; The signal output part of described liquid level detecting sensor, temperature detection sensor, pH value detecting sensor is connected with microcomputer controller signal input part respectively; Described microcomputer controller control output end is connected with the control input end of variable frequency pump, electric control valve, water circulating pump, dredge pump respectively.
Described gland bonnet one side and described corrosion test storehouse hinged; A pair expansion link is provided with between gland bonnet and corrosion test storehouse sidewall; Stainless steel pintle hook lock by being evenly arranged between corrosion test storehouse and gland bonnet fastens; Along corrosion test Hatch Opening along being provided with sealing strip docking groove and putting sealing strip in the inner.
The invention has the advantages that realization carries out erosive carbon dioxide to concrete corrosion test, in process of the test, circulated sprinkling adopts high-pressure atomization shower nozzle, the particle water be atomized combines with subversive gas, considerably increase gas solubility, accelerate corrosion progress, shorten research cycle, realize resources conservation.The invention solves the test of conventional soaking container and can only investigate the impact of environmental baseline on concrete corrosion resistant by the concrete test block even soak test of mortar bar, and corrosion resistance impact can not be investigated expanded range to problem element bearing capacity being affected to aspect, reach the corrosion immersion to some small members or washout test, for the correlativity setting up component corrosion resistance and bearing capacity change provides conveniently.Meanwhile, insulation of the present invention, sealing property are excellent, can realize the corrosion environment of simulating various different parameters type.The Automatic Control dynamic by the operation such as fluid injection, circulation, spray, time liquid, discharge opeing, the gas transmission setting of microcomputer controller program being realized to process of the test or Non-follow control, guarantee that process of the test is more accurate, realize test details control law, improve the accuracy of achievement in research.
