Specific embodiment
In order to preferably explain the present invention, in order to understand, with reference to the accompanying drawing, by specific embodiment, to this hair
It is bright to be described in detail.
Embodiment 1
A kind of test specimen production mold of easy irregular rock direct shear test, which includes the first mold and the second mould
Tool, the first mold and the second mold include pedestal, both side plate, three partitions and stud, wherein the structure of the first mold
Schematic diagram as shown in Figure 1, include first base 1, two the first side plates 2, three first partitions 3, two first of the first mold
Side plate 2 is separately mounted to the front and back two sides of first base 1, can be incited somebody to action by being equipped with the groove of pluggable first side plate 2 on pedestal
Two the first side plates 2 are fixed；The rear and front end of two side plates passes through the first stud 5 respectively and connects with nut, the first side plate 2
Inboard be equipped with spill tongue-and-groove, the two sides and centre for being located at the first side plate are equipped with spill tongue-and-groove, and three first partitions 3 are pacified respectively
Between the spill tongue-and-groove of two the first side plates 2, two mould cavities are formed, the upside of each first side plate 2 is equipped with mountable
The protrusion of cap screw, the nut bolt 6 with rubber pad are mounted on two the first side plates 2 of the first mold.With rubber pad
