The control system can then begin the water penetration test of the test piece according to the set test program.
The control system, the water pressure providing mechanism and the air source are arranged on the lower workbench 33, and the control system controls the air cylinder 24 to act through the electromagnetic valve, which are all the prior art. The pretreated test piece is placed in a test mold 31 of a concrete impermeability instrument, the lower part of the test mold 31 is connected with a water pressure providing mechanism, the water pressure providing mechanism comprises a pressure chamber, the pressure chamber is connected with a water tank through a pipeline, the water tank is connected with a water pump, a valve is arranged in the pipeline, the valve and the water pump are controlled by a control system, and water in the pressure chamber is provided for the test mold 31 through the pipeline.
