Embodiment Construction
[0041] The invention provides a method for measuring rock surface roughness. The invention mainly includes a transparent test plate 6 with hole group distribution, three-layer protective frames 10-12, a strip joint plate 21, a right-angle joint plate 22, a frame-plate joint 14, and a hundred sub-table 5. Refer below Figure 1-Figure 5 And according to the manufacture and measurement process of the embodiment, the measurement method of the invention is described in detail.
[0042] In general, the length and width of the transparent measuring board are equal to (or slightly less than) the length and width of the hollow part of the middle protective frame 11, and greater than the length and width of the upper and lower protective frames 10 and 12 hollow parts, and its thickness is equal to ( Or slightly less than) the thickness of the middle layer protective frame 11, so the transparent measuring board 6 can be completely fixed by the upper, middle and lower three layers of pr...
