Description

Technical Field

[0001] The present invention relates to the technical field of geotextile detection, and in particular to a strength detection device and method based on geotextile. Background Art

[0002] Geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetics. The finished product is in the shape of cloth, generally 4-6 meters wide and 50-100 meters long. Geotextile is divided into woven geotextile and non-woven filament geotextile.

[0003] Strength refers to one of the mechanical properties that indicates the resistance of engineering materials to fracture and excessive deformation. Common strength performance indicators are tensile strength and yield strength (or yield point). Cast iron and inorganic materials do not have yield phenomenon, so only tensile strength is used to measure their strength performance. Polymer materials also use tensile strength. When subjected to bending load, compression load or torsion load, the material's strength performance should be expressed by its bending strength, compression strength and shear strength.

[0004] Existing geotextile strength testing devices usually use linear stretching to test the strength of geotextiles. However, when geotextiles are actually used, the direction of the force they are subjected to is not single. Therefore, when testing, the testing device is not comprehensive enough, resulting in poor testing results. Summary of the invention
