When the concrete sealing device works, the sealing balls 2 are added into the uniformly mixed concrete body 1, the sealing balls 2 are uniformly distributed in the concrete body 1, at the moment, the water inlet holes 4 on the metal shell 3 are sealed by the sealing blocks 5, the sealing balls 2 are effectively prevented from contacting water in the mixing process of the concrete body 1, the expansion blocks 6 in the sealing balls are expanded by the water to influence the subsequent work condition of the sealing balls, meanwhile, the metal shell 3 can play a certain protection effect on the expansion blocks 6, the expansion blocks 6 are prevented from being easily corroded or damaged due to the direct contact with the concrete body 1, meanwhile, after the concrete is paved and solidified into a concrete layer, the sealing balls 2 can be randomly distributed and buried in the concrete layer, the strength of the concrete layer is enhanced, the condition that the concrete layer cracks are generated is reduced, and meanwhile, the sealing blocks 5 in the water inlet holes 4 are made of degradable materials such as starch plastics, make the plugging block 5 can degrade automatically a period of time after the concrete solidifies, thereby make inlet opening 4 be in the open mode, when the crack appears in the concrete and makes plugging ball 2 expose when external environment, the water in the infiltration crack can pass inlet opening 4 and the expansion piece 6 contact of exposing plugging ball 2 this moment, make the expansion piece 6 of inlet opening 4 department expand and bulge from inlet opening 4 after absorbing water, thereby make the expansion piece 6 of bulging from inlet opening 4 can effectually fill the shutoff to the crack, floor concrete layer's seepage prevention ability has been improved greatly.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
