Detailed description of the invention
Defer to technique scheme, as shown in Figure 1, a kind of device measuring tunnel selenolite corrosion, dissolution characteristic, including corrosion bottle 1, the bottom sides distribution of corrosion bottle 1 has bottom osculum 14, corrosion bottle 1 top is provided with the water injection pipe 2 that connect internal with corrosion bottle 1, and water injection pipe 2 stretches into one end of corrosion bottle 1 and is provided with air deflector；Bottom in corrosion bottle 1 is provided with permeable stone bed course 6, and permeable stone bed course 6 is fixed with rock sample 8.
Agent structure of the present utility model includes a corrosion bottle 1, and corrosion bottle 1 is a transparent bottle 13, has opening at the top of bottle 13, and opening is equipped with a bottle stopper 11 with holes；One end of above-mentioned water injection pipe 2 extend into bottle 13 from bottle stopper 11 with holes.Bottle 13 bottom sides has the bottom osculum 14 for getting rid of bottle 13 internal water, multiple in the distribution of bottle 13 bottom sides.
In this programme, the parts for carrying out a comparison testing crucial are mounted in the air deflector that water injection pipe 2 extend in bottle 13 on one end, and in order to coordinate different processs of the test, the air deflector in this programme has two kinds:
The first, as it is shown in figure 1, air deflector adopts taper drainage device 3, taper drainage device 3 includes taper seat 32, and taper seat 32 top is provided with the projection 31 that can be plugged into water injection pipe 2 end；The sidewall of corrosion bottle 1 is provided with the support bar 12 for fixing taper drainage device 3.Air deflector entirety is similar to funnel shaped, after air deflector is fixed on corrosion bottle 1 inside, corrosion water Automatic water-filling pipe 2 arrives container side wall along protruding 31 and taper seat 32 successively, then container side walls flows down, so can reduce current to the impact of solution in container, keep proceeding smoothly of dissolved corrosion test, weaken the water impact impact on test；
The second, air deflector adopts face mozzle, and the end of face mozzle is threaded；After face mozzle is arranged on water injection pipe 2, the lower end of face mozzle is close to the upper surface of rock sample 8.That is, after mozzle installs face to face, the gap between lower end and rock sample 8 upper surface of face mozzle is less, as close possible to rock sample 8 upper surface, so can weaken the current percussion to rock sample 8 top, it is ensured that it is carried out erosion along rock sample 8 surface by uniform fluid flow.
In order to control current in this programme, water injection pipe 2 and drain pipe are mounted on two-way globe valve 5.
Osculum is distributed four in corrosion bottle 1 bottom sides, each osculum is respectively connected with a drain pipe, drain pipe is provided with draining two-way globe valve 5；In the present embodiment as it is shown on figure 3, respectively intake two-way globe valve the 51, first draining two-way globe valve the 5, second draining two-way globe valve the 53, the 3rd draining two-way globe valve the 54, the 4th draining two-way globe valve 55 structural representation.
It addition, device also includes the probe tube 7 of a L-shaped, probe tube 7 is removably connected with drain pipe.
In conjunction with shown in Fig. 4 to Fig. 6, utilize this device carry out tunnel selenolite corrosion, dissolution characteristic test method as follows:
1. the corrosion of selenolite static state and dissolution test
Being inserted by permeable stone bed course 6 bottom corrosion bottle 1, rock sample 8 is placed on permeable stone bed course 6, is inserted by water injection pipe 2 in bottle stopper 11 with holes, threadeds with water inlet two-way globe valve 51.After each parts connect, first draining two-way globe valve the 5, second draining two-way globe valve 53 and the 3rd draining two-way globe valve 54 being closed, the 4th draining two-way globe valve 55 is opened and threaded probe tube 7, is collectively forming U-shaped linker with corrosion bottle 1；Now opening into water two-way globe valve 51, in corrosion bottle 1, injecting solution until after liquid level do not have rock sample 8 certain altitude, closing water inlet two-way globe valve 51.Start timing, dissolved corrosion test starts, and weighs rock sample 8 mass after corrosion at regular intervals according to predetermined testing program, utilizes glue head dropper to draw a certain amount of corrosion solution in probe tube 7 simultaneously, and carry out ion chromatography as early as possible, measure its released ion kind and concentration.According to ion concentration measurement result, rapid preparing equivalent same sex solution adds in corrosion bottle 1, it is ensured that corrosion environment is constant.When in continuous 7 days of the mass change amount of rock sample 8 less than 0.001g, it is believed that corrosion terminates, measure the final corrosion quality of Gypsum Fibrosum rock sample 8 and released ion concentration.
The static dissolved corrosion test of above selenolite, according to testing program, can add solution of different nature, completes the impact on selenolite corrosion of the heterogeneity solution and tests.Whole assay device can be put into temperature control box simultaneously, control to complete temperature to the impact test of selenolite corrosion characteristics by temperature.More than test can disclose corrosion SOLUTION PROPERTIES, temperature, the pH value rule on selenolite corrosion and dissolution characteristic impact.
2. the dynamic corrosion of selenolite and dissolution test
Dynamic corrosion, according to the solution difference to the dynamic corrosion mode of Gypsum Fibrosum in the actual Environmental effect of selenolite, can be divided into surface current corrosion and body stream corrosion two kinds.
Surface current corrosion: permeable stone bed course 6 is inserted container bottom, rock sample 8 is placed on bed course, water injection pipe 2 is inserted in bottle stopper 11 with holes, threaded with water inlet two-way globe valve 51, again surface current conduit 4 is threadeded with water injection pipe 2, open into water two-way globe valve 51, current are made to be flowed downward through rock sample 8 surface by surface current conduit 4, according to testing program, glue head straw is utilized to draw a certain amount of corrosion solution at the first draining two-way globe valve 5 place at regular intervals, carry out ion chromatography, analyze the ionic species in corrosion solution and concentration, weigh the quality after the dynamic corrosion of rock sample 8 simultaneously, until stipulated time or sample corrosion are totally, test completes.
Body stream corrosion: permeable stone bed course 6 is inserted container bottom, rock sample 8 is placed on bed course, taper drainage device 3 is steadily placed on support bar 12, water injection pipe 2 is inserted in bottle stopper 11 with holes, threaded with water inlet two-way globe valve 51, tip is stretched in water injection pipe 2, all draining two-way globe valves 5 cut out, open into water two-way globe valve 51, water filling in container was not until liquid level had rock sample 8 certain altitude, regulate water inlet two-way globe valve 51 and four draining two-way globe valves 5 simultaneously, make four draining two-way globe valve 5 draining total amounts equal with water inlet two-way globe valve 51 total amount of intaking, now can ensure that the liquid level of solution in corrosion bottle 1 is constant.According to testing program, glue head straw is utilized to draw a certain amount of corrosion solution at water discharging valve place at regular intervals, carry out ion chromatography, analyze the ionic species in corrosion solution and concentration, weigh the quality after the dynamic corrosion of rock sample 8 simultaneously, until stipulated time or sample corrosion are totally, test completes；
The dynamic dissolved corrosion test of above selenolite two ways, all can pass through coordinating of inlet valve and flowing water Valve, control corrosion solution flow rate, complete the dissolved corrosion test that selenolite flows down at Dynamic Water dissimilar, different in flow rate, and then disclose the rule between corrosion speed and corrosion and dissolution feature.
