Device for determining the strength of geosynthetic materials under dynamic punching

摘要

The invention relates to the building materials industry, and specifically to the field of testing the strength of woven and nonwoven geotextiles under dynamic punching for use in various branches of construction.;The apparatus comprises a rack, the ring mechanism for clamping a test specimen in a horizontal position, the protective screen, a cone, a guide rod. Between the cylindrical surface of the base of the cone and the guide rod is a force sensor punching electrically connected through an amplifier to a measuring device, the other end of the guide rod through a coupling connected to the rod electric linear motion, which in turn is electrically via a control unit connected to the cone position sensor. Technical result: the ability to extend the functionality and improve the performance of the testing process. 1 yl.
