Embodiment 1

[0033] Embodiment 1: A sample production mold with controllable undulations provided by the present invention, its overall structure is as follows figure 1As shown, adopting the idea of ​​modular design, a groove-shaped positioning base 1, an arc-shaped movable plate 3 and a mold outer frame 2 are designed. The groove-shaped positioning base 1 is a rectangular groove body, see figure 2 , the upper frame of the tank body is provided with a circle of small steps 7, and two T-shaped grooves 6 are arranged in the wide sides of both sides of the tank body, and the arc movable plate 3 is positioned in the groove shape by the screw rod 5 and the nut 4. In the positioning base 1, the screw rod 5 and the nuts 4 at both ends fall on 2 T-shaped grooves 6 provided with the grooved positioning base; The perimeters of the small steps are equal, and notches are arranged in the broad sides of the mold frame 2, see image 3 , the outer frame of the mold is covered outside the arc-shaped mova...

Embodiment 2

[0036] Embodiment 2: use the method for the mold making test model of the embodiment of the present invention 1, operate as follows:

[0037] (a) before using the mold of the present invention to make the test model, first determine the structural surface relief angle and size for the test, and clearly draw the outline of the structural surface relief angle and size on a plane; put two screw rods 5. A nut 4 is fixed at one end, and the laminations 8 are tightly placed on the two screw rods one by one. After the two screws are fitted, adjust the position of each lamination 8 sequentially according to the undulating contour of the structural surface in the drawing, and after obtaining the required undulating angle and shape of the structural surface, fix the other ends of the two screw rods tightly with nuts, so that Prevent the displacement of the laminations from slipping and affect the production of the sample; thus the arc-shaped movable plate 3 is formed.

Abstract

The invention relates to a mould for manufacturing a sample with an undulated structure surface with controllable undulation degree. The mould comprises a slot-shaped locating base, an arc movable plate and a mould outer frame, wherein the slot-shaped locating base is a rectangular slot body, small steps and T-shaped grooves are arranged on an upper frame of the slot body, the arc movable plate is formed by N laminated sheets through lamination and is located in the slot-shaped locating base by screw rods and nuts, the mould outer frame is rectangular and covers the arc movable plate externally, and a lower frame of the mould outer frame is arranged on the small steps of the slot-shaped locating base. A method for manufacturing the sample by the mould comprises the steps of completely sheathing the two screw rods with laminated pieces, regulating the mounting height of each laminated sheet on two screw rods according to the undulated angle and the size of the structure surface of the sample to enable each laminated sheet to be matched with the structure surface in the undulated angle and the size, fixing tightly by using the nuts to form the arc movable plate, coating release agents on the inner wall of the mould frame and the arc movable plate, and pouring casting materials to manufacture the sample, and demolding afer maintenance, thereby obtaining the sample. The mold is simple in structure and can easily control the undulation degree and the size of the structure surface.

Description

technical field [0001] The invention relates to a mold for making a sample of a waviness structure surface with controllable undulations and a method for using it, in particular to a mold for making a model of a waviness structure surface for a direct shear test and a method for using it, and is especially suitable for making A set of undulating structural surfaces in which the upper and lower plates coincide with each other. Background technique [0002] Rock structural planes are geological interfaces with different origins and characteristics in rock bodies, including material differentiation planes and discontinuous planes, such as bedding, schistosification, faults and joints. The existence of structural planes destroys the continuity and integrity of rock mass, and it is precisely because of the existence of structural planes that landslide disasters often occur on rock slopes. The key to the slope stability puzzle. [0003] The shear strength of the structural plane...
