Manufacturing tool, die and method of adjustable prefabricated joint sample

Abstract

The invention relates to a manufacturing tool, die and method of an adjustable prefabricated joint sample. The manufacturing tool comprises a bottom plate, wherein inserting openings are reserved in the bottom plate, the inserting openings are used for inserting and connecting vertical plates, and each vertical plate is arranged vertical with the bottom plate; the bottom plate comprises a list offirst inserting plates which are spliced with one another, the first inserting plates are parallel to one another, and a distance piece is arranged between each two first inserting plates; the lengthof each second inserting plate is smaller than the length of each first inserting plate, and the first inserting plates and the second inserting plates are spliced to form an I-shaped bottom plate structure; a gap is formed between each two first inserting plates which are connected through one second inserting plate, and the gaps form the inserting openings; and the number of the second insertingplates can be adjusted to realize the adjustment of the size of the inserting openings. According to the manufacturing tool, die and method of the adjustable prefabricated joint sample, the position,the thickness and the width of the third inserting plates inserting into a rock-like material can be adjusted, the displacement of the third inserting plates in the vibrating process of the rock-likematerial is avoided, and a large number of the third inserting plates do not need to be customized according to joints, so that the economical efficiency is good.

Description

technical field [0001] The invention belongs to the technical field of rock mechanics, and in particular relates to an adjustable prefabricated joint sample production tool, mold and method. Background technique [0002] Most of the engineering rock mass has been disturbed by multiple geological tectonic movements, and contains many different levels of joints and weak surfaces. The rock mass with joints has completely different properties from the complete rock mass, especially under unloading conditions, the mechanical properties of the rock mass are more different. The unloading effect makes the original cracks in the rock mass expand and penetrate, and even create new cracks, the connectivity of the rock mass increases, the permeability increases, the tensile strength decreases sharply, and the quality of the rock mass deteriorates rapidly. [0003] The rock masses encountered in engineering are all jointed rock masses with different levels of fractures. Therefore, the m...

AI Technical Summary

Problems solved by technology

[0005] (1) It is difficult to ensure whether the steel plate is inserted vertically and whether the insertion position is accurate and meets the requirements when manually inserting the plate (the above-mentioned thin steel plate), and there is a large error

[0006] (2) When the rock-like material in the pouring box is vibrated, problems such as deflection and positional displacement of the plate are prone to occur

[0007] (3) When making joints of different lengths and thicknesses, a large number of plates (thin steel plates) need to be customized, the whole process is cumbersome and economical
