Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that: there is a water flow obliquely flowing towards the geotextile in the infiltration water inlet cylinder, so there is infiltration in the oblique direction of the water flow on the geotextile, so the permeability of the vertical direction of the water flow of the geotextile cannot be tested solely. This will affect the experimental accuracy of the vertical permeability of geotextiles

Abstract

The invention relates to a geotextile vertical permeameter. The geotextile vertical permeameter comprises a case, the vertical permeameter further comprises an experimental water tank mounted on the case; the experimental water tank comprises a permeation tank, permeation holes are formed in the bottom of the permeation tank, and sample geotechnical cloth is fixed to the permeation holes; the sample geotechnical cloth is covered with a flow blocking pipeline with openings in the two ends, the permeation box is provided with a water inlet pipe for inputting water into the permeation box, and one side of the permeation box is provided with a measuring device for measuring the amount of water permeated from the permeation box. The test device can improve the test precision of the vertical permeability characteristic of the geotechnical cloth.

Description

technical field [0001] The present application relates to the field of geotextile detection, in particular to a geotextile vertical penetrometer. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. The permeability of geotextiles is an important hydraulic characteristic of geotextiles, and it is an important indicator in filtration standards and other related hydraulic design. The good permeability and reverse filtration performance of geotextiles can improve the seepage operation in the building and enhance the stability of the building, so geotextiles need to meet industry standards. [0003] Permeameters in the related art generally include water inlet pipes, infiltration water inlet cylinders, infiltration drainage cylinders, and collection barrels. When in use, geotextiles are clamped between the infiltration water inlet cylinders and the infiltration drain...
