【Scope of application】: It is used to determine the properties of tensile creep and tensile creep fracture of geotextiles and geotextiles and related products. [Meet the standard]: ISO 13431, GB/T 17637, JTG E50 T1129, SL/T 235-1999 and other standards [Instrument features]: 1. Number of stations: 4 (2, 6, 12 other stations can be selected), each station can work independently without affecting each other. 2. Use an encoder to record creep elongation, and the recording accuracy is high. 3. Use air pressure instead of weight weight, which is convenient to apply constant load. 4. Select SMC electric proportional valve to adjust the air pressure in real time to ensure that the applied pressure is constant. 5. The action of the Yatac cylinder is selected, the small force value is applied by the small cylinder, and the pressure is applied by the large cylinder with the large force value. 【Technical Parameters】: 1. The accuracy of the length of tensile creep: 0.02mm; 2. Creep application load range: 0.5KN~18KN; 3. Single tensile creep: 250mm; 4. Curve interval point record: (0~1) h, 1s; (1～24) h 、1 min； (24h～42d) 、1h； 5. Timing accuracy: ±1s; 6. Test width: 200mm; 7. Pressure adjustment accuracy: 0.005MPa; 8. Initial separation distance: 240~500mm; 9. Working power supply: Ac220V, 50Hz, 500W; 10. Machine size: 2000mm×400mm×1800mm (L×W×H); 12. Weight of the whole machine: about 200kg;
