Subsequently, the staff can control the electric heating wire 2 530 to work, conduct heat through the heat conduction frame 531, and dry the soil in the storage case 520, so that it can simulate the loss of the concrete sample 560 when the soil is dry and corroded in the actual scene. At the same time, the electric heating wire 113 can be controlled to turn on, and the actual high temperature scene can be simulated in the curing room 110;

At the same time, the dehumidifier 130 works to dry the curing room 110, and the ultrasonic humidifier 150 can humidify the curing room 110 when it is turned on, and it is the main humidification method, and the electric heating wire in the water storage frame 120 113 can heat the water to make it evaporate to assist humidification treatment, and timely control the temperature change in the curing room 110 according to the above simulation, so as to perform the curing test on the concrete sample 560 more accurately;

Further, in order to continue to improve the quality of the concrete test experiment during the concrete curing experiment, on the basis of the above test, when simulating the impact of the gravity of the vehicle on the concrete, increase the strength test experiment to reflect the actual Effects on concrete in complex situations to increase data accuracy and credibility;

Therefore, when the staff is testing the strength of the concrete sample 560, they can control the opening of the hydraulic cylinder 710, and the downward movement of the output end of the hydraulic cylinder 710 can drive the force measuring plate 720 and the pressure measuring seat 740 to move downward, and the pressure measuring seat 740 Move down to press down on the concrete sample 560, because the pressure measuring seat 740 is slidingly connected with the force measuring plate 720, the force reflected by the concrete sample 560 on the pressure measuring seat 740 can make the bump 742 squeeze the pressure sensor 730, and In this test, the force exerted on the concrete sample 560 is moved downwards, so as to reasonably control the compressive strength of the pressure measuring seat 740 on the concrete sample 560, and then in the process of carrying out the above test on the concrete sample 560, the concrete sample 560 strength test, in order to improve the accuracy and feasibility of the concrete sample 560 curing test, and bring accurate judgment for the follow-up actual curing work.
