Background

As the name implies, the concrete impermeability machine is mainly used for the test of the concrete impermeability and the measurement of impermeability grade.

The concrete impermeability machine is characterized in that a concrete sample is placed in a detection groove, the detection groove is sealed, a constant-pressure environment is manufactured in the detection groove by water, and then whether the sample leaks under the current pressure environment or not is detected. In the concrete measurement process, a plurality of samples need to be manufactured to participate in the detection together in order to improve the detection precision. A typical concrete permeation resistant engine has six test slots, and then 6 samples of the same batch are prepared correspondingly.

In the detection process, the water pressure in the detection groove can automatically rise step by step under the control of a system so as to detect the maximum impermeability of the concrete. The duration of the corresponding detection will be longer and the end time will be indeterminate. If a plurality of batches of concrete are in line to be detected, operators need to pay attention to the working condition of the impermeability machine at any time, and after the detection of the concrete in the current batch is finished, the operators need to replace the concrete sample in the next batch immediately. Because the number of samples is large, the steps of opening the detection groove and sealing the detection groove are troublesome, the time required for replacement is long, and the detection efficiency is low.
