[specific embodiment]
The structure of the test device of the Corrosion Reinforcement area of section of the utility model embodiment 1 as shown in figure 1, including frame,
The container 11 of automatic recorder 12, computer system of weighing, reinforcing bar lowering means and dress liquid.Weightometer 12 being capable of basis
The time interval that is previously set records reading.
Frame includes constant current bottle rack 13 and tank support 14.
Computer system includes processor, input unit and display device, the data output end of recorder 12 of weighing automatically
Connect the processor of computer system.
Reinforcing bar lowering means includes reinforcing bar chuck 1 and chuck descending mechanism.
Chuck descending mechanism includes constant current bottle 2, Rectangular Water Trough 3 and resilient suspension.The constant current bottle 2 for installing water is suspended on constant current
On bottle rack 13, the top of tank 3 is arranged in, constant current bottle 2 has an air inlet pipe 201 and an outlet pipe 202, constant current bottle 2 goes out
Water pipe 202 is woven hose, under the liquid level of the lower end insertion screw clamp 3 of outlet pipe 202.The constant current bottle outlet in bottle of air inlet pipe 201
The position of mouth is Q, and the position of the liquid level of tank 3 is P；Because the cross-sectional area of tank 3 is very big, during equipment works, liquid
The position P in face is basically unchanged.
Rectangular Water Trough 3 is arranged on tank support 14 by resilient suspension, and resilient suspension includes pressing the corner of 3 rectangle of tank four
4 extension springs 5 of position arrangement, the upper end of extension spring 5 is fixed on tank support 14, and the lower end of extension spring 5 is fixed on tank 3.
Reinforcing bar chuck is suspended on the centre of the lower section of tank 3 by nylon hoist cable 16；Reinforcing bar chuck 1 is clipped in tested steel
The top of muscle 100.
Container 11 is placed on the table top of the automatic recorder 12 of weighing in the lower section of reinforcing bar chuck 1, and test fluid is contained in container 11
1101, during test, tested reinforcing bar 100 falls, and lower end is entered into the liquid level of test fluid.Test fluid 1101 preferably with methyl alcohol,
The less liquid of the proportion such as ethanol or gasoline.Using gasoline as solution, can reduce due to error caused by buoyancy, gasoline
Density be 0.7g/cm3, the density of water is 1g/cm3, error 30% can be reduced as test fluid with gasoline.
The test process of the utility model embodiment 1 is as follows：
1) experimental rig is got out, the switch of woven hose is opened, the decrease speed of tested reinforcing bar is demarcated；When needing, pass through
Height in regulation air inlet pipe insertion constant current bottle adjusts the decrease speed of tested reinforcing bar to setting value；
2) decrease speed of the tested reinforcing bar that will be demarcated is input into computer system；
3) recover experimental rig to original state, start automatic weigh recorder and computer system, then open woven hose
Switch, tested, tested reinforcing bar is progressed into the test fluid of container；Automatically between weighing recorder according to set time
Computer system is transported to every the qualitative data to reading and by qualitative data and corresponding time value；
4) speed, qualitative data and the corresponding time value that computer system declines according to tested reinforcing bar calculate Corrosion Reinforcement
The axially distributed data of remaining cross-section value and/or corrosion ratio.
The utility model above example employs the principle of constant current bottle, i.e.,：When on-test, in constant current bottle at PQ
There is the discrepancy in elevation, communicated with external atmosphere pressure at Q, be i.e. pressure at point Q is constantly equal to atmospheric pressure.The outlet pipe 202 of constant current bottle 2
When opening, liquid flows to P in the presence of pressure in constant current bottle, and its interior liquid level declines constantly, determines flow rate of liquid
Be the discrepancy in elevation at the points of PQ two, extraneous air is entered in vial by Q points, that is to say, that let the liquid out bottle mouth position P's
Pressure, is actually equal to pressure difference of the liquid in 2 points of PQ, i.e. p=ρ g △ h, the discrepancy in elevation at PQ is △ h.Therefore, as long as liquid level
Q points are not dropped to also, it is V that the speed that liquid flows out from aperture P is permanent.This is the constant principle of constant current bottle flow velocity.
The structure of the test device of the Corrosion Reinforcement area of section of the utility model embodiment 2 as shown in Fig. 2 with embodiment 1
Unlike, the outlet pipe 202 of constant current bottle 2 is the common flexible pipe with switch, and the delivery port of outlet pipe 202 is located at the liquid of tank 3
The top in face, P points are the delivery port of outlet pipe 202, and level change does not influence the position of P points in tank 3.
The structure of the test device of the Corrosion Reinforcement area of section of the utility model embodiment 3 as shown in figure 3, with embodiment 1
Unlike, the outlet pipe 202 of constant current bottle 2 is woven hose, although under the liquid level of the lower end insertion screw clamp 3 of outlet pipe 202, but
One passage 203 is arranged at the top of woven hose cyclopentadienyl phenanthrene dropper, allows luxuriant phenanthrene dropper inside and atmosphere, and P points are luxuriant phenanthrene dropper
In dropper mouthful, level change does not influence the position of P points equally in tank 3.
The test device simple structure of the utility model above example, power, easy to operate is not needed, measuring accuracy can
To meet detection needs.
