This instrument is used to determine the ability of geotextile and related products to resist the penetration of steel cones falling from a fixed height, and to characterize the degree of damage caused to geotextiles by dropping sharp stones on the surface of geotextiles. 【Relevant Standards】

GB/T17630, ISO 13433, JIG E50 T1128 and other standards.

【Scope of application】: This instrument is used to determine the ability of geotextile and related products to resist the penetration of steel cones falling from a fixed height, and to characterize the degree of damage caused to geotextiles by dropping sharp stones on the surface of geotextiles. [Meet the standard]: GB/T17630, ISO 13433, JIG E50 T1128 and other standards. 【Product Features】: 1. Box structure (to avoid injury to the operator when the cone falls). 2. Precision motor control cone lifting. 3. Color touch screen display, control, Chinese and English interface, menu operation mode. 【Technical Parameters】: 1. Inner diameter of the clamping ring: Ф150±0.5mm; 2. The distance from the steel cone spire to the specimen: 500±2mm; 3. Stainless steel cone angle: 45º, total mass: 1000±5g; 4. Measuring cone weight: 600±5g; 5. Power supply: 220V, 50Hz, 50W; 6. Overall dimensions: 540mm×470mm×1130mm (L×W×H); 7. Weight: 50Kg; 【Working Principle】: The geotextile specimen is clamped horizontally in the clamping ring, so that the steel cone of the specified quality falls from a height of 500mm on the specimen, forming a hole on the specimen, and then inserting a small angle measuring cone marked with a scale into the hole to measure the degree of penetration.
