Above the frame 2, an ultrasonic generator 8 is provided on one side of the inner wall of the detection shell 3, and an ultrasonic receiver 9 is provided on the other side of the inner wall of the detection shell 3. In this embodiment, the heating mechanism can be used to precisely control the temperature and simulate the aging process of concrete under different climatic conditions.

[0018] This utility model discloses a testing device for determining the durability of concrete components. The drainage mechanism includes a drainage pipe 10, which is installed at the bottom of the testing platform 1 and connected to the drainage hole 5. A first electric valve 11 is provided on the drainage pipe 10. By opening the first electric valve 11, the liquid in the storage tank 4 can be discharged through the drainage hole 5 into the drainage pipe 10 to remove corrosive liquid, facilitating the recovery of corrosive liquid. By closing the first electric valve 11, the corrosive liquid can accumulate in the storage tank 4 to soak and corrode the concrete sample.
[0019] This utility model discloses a testing device for determining the durability of concrete components. The ventilation mechanism includes a ventilation pipe 12, which is installed on the rear side of the testing shell 3 and extends into the interior of the testing shell 3. A second electric valve 13 is provided on the ventilation pipe 12. There are two ventilation pipes 12 arranged symmetrically. The two ventilation pipes 12 facilitate the connection of external ventilation equipment to quickly exhaust air. By switching the second electric valve 13, it is easy to close the device when exhaust is not required.
[0020] This utility model discloses a testing device for determining the durability of concrete components. The pressure testing mechanism includes a hydraulic device 14 and a pressure plate 15. The hydraulic device 14 is installed at the top of the testing shell 3, and the pressure plate 15 is installed at the output end of the hydraulic device 14 and located above the storage frame 2. The hydraulic device 14 controls the pressure plate 15 to move downward, thereby contacting and applying pressure to the concrete sample on the support groove 6. This facilitates the testing of structural strength at different stages of corrosion, thus making it easier to test durability.
[0021] This utility model discloses a testing device for determining the durability of concrete components. The heating mechanism includes a heating device 16, which is installed on the top of the inner wall of the testing shell 3. By directly setting the heating device 16 on the top of the inner wall of the testing shell 3, the interior of the testing shell 3 can be directly heated.
[0022] This utility model discloses a testing device for determining the durability of concrete components. The heating device 16 is provided in two symmetrical arrangements, which can further improve the heating efficiency.
[0023] This utility model discloses a testing device for determining the durability of concrete components. The liquid supply pipe 7 is inclined towards the center of the storage frame 2.

By using two symmetrically arranged liquid supply pipes 7 inclined towards the center of the storage frame 2, corrosive liquid can be delivered to the concrete sample more efficiently.
[0024] This invention relates to a testing device for determining the durability of concrete components. During operation, the concrete sample to be tested is placed on a support groove 6 using a storage frame 2. The concrete sample is supported by the bottom edge of the support groove 6. A pressure testing mechanism is then used to perform a compressive strength test on the concrete sample. A heating mechanism heats the internal environment of the testing shell 3 to simulate the compressive strength of the concrete sample under high-temperature conditions. A corrosive liquid, such as sodium sulfate solution, is delivered to the concrete sample on the support groove 6 via a supply pipe 7. Excess liquid is discharged through a drain hole 5 on a storage tank 4 and finally fully utilized through a draining mechanism, thereby simulating… After the concrete sample is affected by external corrosion, a pressure testing mechanism is used to retest it. By supplying the amount of corrosive liquid, the environmental corrosion situation in the service environment can be simulated. After accumulating, the pressure testing mechanism is used to test it again. After each pressure test and when corrosive liquid is supplied, ultrasonic waves are emitted by ultrasonic generator 8. After passing through storage frame 2 and concrete sample, the ultrasonic waves are received by ultrasonic receiver 9 on the other side of detection shell 3. This allows the state of concrete at different stages to be obtained, thereby judging the durability data of concrete. The ventilation mechanism facilitates cooling and ventilation. Then the door mechanism is opened to prevent the gases emitted by the corrosive liquid from causing harm to the human body.
