Description

Technical Field

[0001] The utility model patent relates to a mold, in particular to a three-part cylindrical mold which can prefabricate tailings consolidation materials with cracks. Background Art

[0002] In the current mineral resource processing process, a large amount of mine tailings have caused a strong impact on the environment. In the laboratory, cement is added to the tailings through a series of process treatments to form a consolidated body with a certain strength, which can be used to fill gaps and enhance the stability of the foundation. Therefore, tailings consolidation treatment has considerable value. Because of the influence of construction during or after the formation, there will be cracks in the tailings consolidation body, so it is necessary to simulate the stress concentration problems that may be involved in the specimen by creating cracks in the material specimen. However, there is currently a lack of a practical, economical, and easy-to-demold tailings consolidation material mold. Based on the above introduction, it is necessary to design a tailings consolidation material mold that can create cracks at any angle. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a three-part cylindrical mold which is convenient to demould, simple in structure and economical to manufacture and can prefabricate tailings consolidation materials with cracks.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A three-part cylindrical mold for prefabricating tailings consolidation materials with cracks, comprising: an arc piece, an open-hole arc piece, a base, a knob-type crack angle determiner, and an insert. The arc piece is one-third of a cylinder, and the arc pieces can be mortise-jointed with each other, and the connection resembles the number "5". The base is a sheet-type cubic structure and has an annular groove on the upper surface. The inner and outer diameters of the groove are consistent with the inner and outer diameters of the cylinder wall of the cylinder formed by the arc pieces. The mold is constrained by fitting the groove of the base with the inner and outer walls of the cylinder formed by the three arc pieces, so that it can be placed stably. The open-hole arc piece has a circular hole for installing a knob-type crack angle determiner. The knob-type crack determiner is shaped like a truncated cone, and the diameter of the truncated cone is consistent with the size of the circular hole of the open-hole arc piece, and the outer surface of the truncated cone has an angle scale on the periphery; a small rectangular hole is opened inside the truncated cone, and is used in conjunction with a key-shaped insert to prepare cracks of any angle. The insert is shaped like a key, and the cross-sectional size is consistent with the cross-sectional size of the opening of the knob-type crack determiner.

[0006] By adopting the above technical solution, the advantages of this utility model are:

[0007] (1) The structure is simple and economical, and easy to disassemble and assemble.

[0008] (2) It is convenient to prepare cracks at any angle and demoulding is easy. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the present invention.

[0015] Figure 1 In the invention, a three-part cylindrical mold for prefabricating tailings consolidation materials with cracks is provided, comprising: a base 1, an arc piece 2, an arc piece with a hole 3, a knob-type crack angle determiner 4, and an insert 5; the arc piece 2 is one-third cylindrical, and the arc pieces can be mortise-jointed with each other, and the connection resembles the number "5". The base 1 is a sheet-type cubic structure and has an annular groove on the upper surface. The inner and outer diameters of the groove are consistent with the inner and outer diameters of the cylinder wall of the cylinder formed by the arc pieces. The mold is constrained by fitting the groove of the base with the inner and outer walls of the cylinder formed by the three arc pieces, so that it can be placed stably. The circular hole of the arc piece with a hole 3 is used to install the knob-type crack angle determiner. The knob-type crack determiner 4 is a frustum, the diameter of which is consistent with the size of the circular hole of the opening arc plate, and the outer surface of the frustum has angle scales on the periphery; a small rectangular hole is opened inside the frustum, which is used in conjunction with a key-shaped insert 5 to prepare cracks of any angle; the insert 5 is shaped like a key, and the cross-sectional size is consistent with the cross-sectional size of the opening of the knob-type crack determiner.

[0016] When making the test piece, the two arc pieces 2 and the perforated arc piece 3 are placed in the groove of the base 1, and the three arc pieces 2 and 3 are mortised and tightly fitted. Then the geotechnical material is poured into the cylindrical closed space formed by the three arc pieces 2 and 3, and the knob-type crack determiner 4 is rotated to the required angle, and then the insert 5 is inserted, and the preparation of the test piece is completed after the material solidifies.

[0017] When demoulding, first pull out the insert 5, and then separate the three arc pieces 2 and 3, and the demoulding of the test piece is completed.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
