Special clamp suitable for tensile test of gabion mesh

Abstract

The invention provides a special clamp suitable for a tensile test of a gabion mesh. The clamp comprises an upper clamp body, a lower clamp body and bolts used for installation and connection; whereinthe upper clamp is a butt-clamping clamp and is composed of two symmetrically-arranged upper clamping devices, and the lower clamp is a butt-clamping clamp and is composed of two symmetrically-arranged lower clamping devices; according to the special clamp, the rubber pads are embedded in the arc-shaped grooves and the clamping positions of the clamping devices; the damage to the gabion mesh during the test is reduced; under the joint connection action of a plurality of bolts, the mesh wires and the side wires at the twisted-pair part of the gabion mesh have the same stress characteristic andmotion state; the arc-shaped groove of the clamping device solves the problem of stress concentration of the gabion mesh caused by the clamp, ensures that the gabion mesh cannot generate dislocationand slippage after being clamped, and ensures the stability of the tensile test process. The clamp is easy to machine and manufacture and convenient, efficient and rapid to use, and the adverse effecton a clamped component is greatly reduced.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and in particular relates to a special fixture suitable for tensile tests of gabion mesh sheets. Background technique [0002] With the continuous development of modern infrastructure construction, in order to meet the stability of the slope and at the same time consider the coordination with the surrounding environment, the ecological protection technology of gabion gabion has been widely used in river channel management and slope support projects. . In order to clarify the mechanical properties and failure modes of the gabion mesh, it is necessary to carry out a systematic tensile test of the gabion mesh. In order to obtain reasonable test results and correct mechanical parameters, a suitable gabion mesh fixture is the key to the success of the test. Because unreasonable clamps will cause certain damage to the mesh when clamping the mesh, it will also lead to uneven stress on the gabio...
