Embodiment 1

[0036] The embodiment of the present invention provides a method for manufacturing a real rock specimen with transparent cracks, such as figure 1 As shown, the production method includes:

[0037] Step 101: Select a cross section parallel to the bottom surface on the real rock specimen of the cylinder, and select the first processing point and the second processing point on the outside of the cross section, and the connection line between the first processing point and the second processing point Pass through the center of the section.

[0038] Step 102: Clamp the real rock test piece on the bench drill, and penetrate the first processing point and the second processing point through the bench drill to form a through hole.

[0039] Step 103: Insert the real rock test piece into the mold, where the mold includes a first mold sleeve and a second mold sleeve. Both the first mold sleeve and the second mold sleeve are provided with processing grooves. The second mold set is used to clamp...

Embodiment 2

[0044] The embodiment of the present invention provides a method for manufacturing a real rock specimen with filled permeable cracks, see figure 2 , The method includes:

[0045] Step 201: Select a cylindrical real rock specimen with a diameter of at most 50mm. Preferably, the length of the real rock specimen may be 100 mm. It should be noted that in other embodiments, the length of the real rock specimen is not limited to the above-mentioned preferred value, but may also be other resins, which is not limited by the present invention.

[0046] When realizing, real rock specimens can be made by carving and polishing the whole piece of rock. It should be noted that the specific material of the real rock specimen can be changed according to actual needs, and the present invention does not limit this.

[0047] Step 202: Select a cross section parallel to the bottom surface on the real rock specimen of the cylinder, and select the first processing point and the second processing point ...

Abstract

The invention discloses a manufacturing method of a real rock specimen having through cracks, belonging to the technical field of rock specimen manufacture. The method comprises the steps of selecting a cross section on the cylindrical real rock specimen, wherein the selected cross section is parallel to the bottom surface; respectively selecting a first processing point and a second processing point at the outer side of the cross section, wherein the connecting line between the first processing point and the second processing point passes through the center of a circle of the cross section; enabling the real rock specimen to be clamped on a bench drill, and penetrating the first processing point and the second processing point by using the bench drill to form through holes; inserting the real rock specimen into a mould, wherein the mould comprises a first die sleeve and a second die sleeve, and two processing grooves are respectively formed in the first die sleeve and the second die sleeve; enabling the first processing point and the second processing point to be respectively aligned with the processing groove of the first die sleeve and the processing groove of the second die sleeve; cutting the through holes to enable the shapes of the through holes to be the same as those of the processing grooves, and forming the non-filling through cracks in the real rock specimen. The method can be used for manufacturing the real rock specimen having the through cracks.

Description

Technical field [0001] The invention belongs to the technical field of rock specimen manufacturing, and particularly relates to a method for manufacturing a real rock specimen with permeable fissures. Background technique [0002] When studying the mechanical properties of rock masses, it is often necessary to use various rock specimens. Since most of the real rock masses have permeability cracks, and the permeability cracks will affect the mechanical properties of the rock mass, in order to be able to To accurately obtain the mechanical properties of the rock mass with permeable fissures, the corresponding rock specimens with permeable fissures should be used in the research process. At present, rock-like materials, such as gypsum, cement, mortar, etc., and other mixtures are prepared and plasticized in a certain proportion to make simulated rock, and cracked pieces, metal strips, polymer thin strips, etc. are added during the plasticization process to make the obtained The roc...
