Problems solved by technology

[0007] (1) Most of them use the secondary pouring molding process supplemented by high-strength mortar to smear the joints. This process results in a poor fit between the upper and lower walls of the rock fracture surface model and cannot reflect the real situation of the fracture surface; while the surface shape of the rock fracture surface is An important factor affecting its shear strength, so it will cause a large error in the experimental results
[0008] (2) It is very difficult to locate the fracture surface. Every time the parameters of the fracture surface are adjusted, the mold needs to be remade. The work efficiency is low, the

Embodiment 1

[0034] Such as figure 1 As shown, the present embodiment includes 4 chutes 1, 3 steel sheet positioning bars 2, 2 sliding bars 3, 4 steel sheets 4, 1 protractor 5, bolts 6, and 4 steel sheet fixing sheets 8.

[0035] The test block mold 7 used in this embodiment is a steel mold with a size of 150×150×150 mm (length×width×height), that is, the length of the side wall of the test block mold 7 is 150 mm. The size of chute 1 is 170×20×10mm (length×width×height), and the size of its straight slot hole is 150×6×10mm (length×width×height). On the top of the 4 side walls of the test block mold 7, and the slotted side faces up. The size of the steel sheet positioning rod 2 is 310×15×15mm (length×width×height), the size of the through groove is 250×3×15mm (length×width×height), and there are round holes with a diameter of 8mm at both ends. The axial direction of the circular hole is perpendicular to the axial direction of the steel sheet positioning rod 2, that is, when the sliding ro...

Abstract

The invention discloses a mould for manufacturing a fissure surface of a rock like test block. The mould comprises a sliding groove, a sheet steel locating rod, a protractor, a sliding rod and a sheet steel, wherein the sliding groove is a long strip type metal component provided with a straight groove hole; the sheet steel locating rod is a metal rod; the sliding rod is a metal rod marked with ascale; a sheet steel fixing sheet is a hard sheet provided with a notch and stuck on the bottom surface of the test block mould; the sliding groove is fixed on the top of the side wall of the test block mould; the sheet steel locating rod is fixed above the sliding groove; the circle centre of the protractor passes through any bolt and is fixed above the sheet steel locating rod; the sliding rod passes through holes at two ends of the sheet steel locating rod and is vertical to the sheet steel locating rod; one end of the sheet steel is fixed in a through groove of the sheet steel locating rod; and the other end of the sheet steel is clamped in the notch of the sheet steel fixing sheet. The mould disclosed by the invention is capable of conveniently and rapidly adjusting parameters of thefissure surface of the test block, such as an inclination angle, an interval, a communication rate and the like. The mould is easy to process and can be repetitively utilized, thus, the manufacture efficiency and the precision of the test block are increased.

Description

technical field [0001] The invention relates to the technical field of rock-similar model tests, in particular to a mold for making the fissure surface of a rock-like test block. Background technique [0002] The existence of fissure surfaces in the rock mass destroys the integrity and continuity of the rock mass structure, and the strength and deformation properties of the fissure surfaces are different, resulting in differences in the strength and deformation characteristics of the rock mass. In order to test and investigate the deformation and strength characteristics of rock mass with multiple groups of fracture surfaces, the main research method is the model test method. However, due to the variable and complex factors such as the spacing, length, connectivity and inclination angle of the fracture surfaces of the rock mass, it is very difficult to make rock-like test blocks when conducting model tests on rock materials containing multiple groups of fracture surfaces. T...
