Description
Technical Field
[0001] The utility model belongs to the technical field of geotextile detection, in particular to a geotextile vertical permeability detector. Background Art
[0002] Geotextile is a water-permeable geosynthetic material made of synthetic fibers through needle punching or weaving. The permeability of geotextile is an important hydraulic property of geotextile. The good permeability and anti-filtration performance of geotextile can improve the seepage operation in the building and enhance the stability of the building. The geotextile permeameter is a special equipment for vertical permeability performance testing of geotextile materials. Through testing, it is judged whether the water permeability of geotextile meets the industry standards.
[0003] Based on the above, the existing geotextile permeameter used for testing the vertical permeability of geotextiles has a simple structure, and has the disadvantages of being cumbersome to operate, slow to detect, and low in detection accuracy. When in use, the existing detector cannot fix the geotextile, and the detection requires water flow to impact the geotextile. The middle part of the geotextile is easily bent and deformed in the direction of the drainage cylinder after being impacted by the water flow, which affects the experimental accuracy of the staff when testing the permeability of the geotextile in the vertical direction of the water flow. At the same time, the overflow detection requires the overflow water to be discharged into the container through the water intake first, and then poured from the container into the measuring cylinder for measurement. Not only is the operation cumbersome and time-consuming, but water may be lost during the operation, resulting in large measurement errors. Utility Model Content
