As long as the inclination angle in any one crack, size or position change, it is required for remaking and replacement is pasted onto mold bottom surface
On steel disc fixinig plate, this can not only make the complex manufacturing process of rocks sample, and can increase the making of rocks sample
Cost.(3) since the slide bar in the mold passes through the Kong Bingyu steel discs locating rod at steel disc locating rod both ends to keep vertical, quilt
The steel disc locating rod that the same group of litter being mutually parallel passes through be always in the state that is mutually parallel, also, by slide bar and
When protractor adjusts the position of steel disc locating rod, each steel disc being fixed in same steel disc locating rod is to be mutually related, because
Mobility during this adjustment is low, and the variable-angle using the crack dip of more crack rocks samples of the Mold Making is also
It is relatively limited, lead to that rock bridge length and the adjustment mode of the rock bridge angle of cut are relatively limited, can not arbitrarily adjust, thus are difficult to meet
