In order to obtain large rock materials, two methods are usually used. One is saw cutting, which has a high yield rate, but low efficiency and high production cost; the other is general blasting cutting, which has high efficiency and low cost, but relatively low yield rate.

[0006] In a preferred embodiment, the thickness of the first sealing ring edge is 2 mm, the outer diameter of the sealing ring is 80 mm-105 mm, and the inner circle of the sealing ring is elliptical.

[0007] In a preferred embodiment, the length of the main body is 4M-5M.

[0008] In a preferred embodiment, the main body is made of PVC material.

[0009] In a preferred embodiment, the length of the long expansion portion is 500mm-700mm.
