[0002] Ready-mixed concrete refers to a concrete mixture consisting of cement, aggregates (such as sand and stone), water, and admixtures and additives added as needed. It is measured and mixed at a mixing station and then sold. It is then transported to the place of use by a transport vehicle within a specified time. In order to ensure the waterproof performance and structural durability of ready-mixed concrete, it needs to be tested for permeability.

[0003] During the inspection, first place the corresponding concrete column on the inner side wall of the fastening sleeve, then use the flattening machine to flatten it. After flattening, put the sealing ring on the corresponding position of the workbench, and then install the fastening sleeve with bolts, and then start the corresponding switch to perform the inspection.
