The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. At least one embodiment of the utility model provides the following technical scheme:
in the figure, the vibration isolation base plate comprises an upper base plate 1 and a lower base plate 2; the upper surface of the upper backing plate 1 is provided with trapezoidal blocks 3 at intervals, the axle center of each trapezoidal block 3 is provided with an axle hole 4, concrete is poured in the axle hole, and the upper bottom of each trapezoidal block 3 is connected with the upper backing plate 1. Trapezoidal connectors are arranged between the upper cushion plate 1 and the lower cushion plate 2 at intervals;
