Background
The geogrid needs to be subjected to a tension test, but the geogrid to be tested cannot be clamped and fall off due to the fact that the clamping problem in the tension test, in order to solve the problem that the geogrid is easy to slip and fall off when being clamped, the Chinese patent CN202220371322.7 is used for tensioning and positioning the geogrid by arranging a groove in a fixed block and a movable block in the groove, placing a clamping section of the geogrid between the clamping section and the groove and gradually clinging to the inclined surface of the groove by pulling the geogrid;
although this approach increases the contact area between the clamp and the geogrid to some extent, thereby improving the existing problem of slipping during testing, it still suffers from the following disadvantages,
on one hand, the distance between the movable block and the groove cannot be too large, otherwise, the effect of clamping and positioning the geogrid is affected; the spacing between the movable block and the groove is too small, so that the difficulty in placing the geogrid between the movable block and the groove is increased;
on the other hand, most of the existing stretching machines carry out stretching test on the geogrid by means of up-and-down movement, and the clamping mode of the scheme is that the clamping end of the geogrid to be tested is firstly placed between the movable block and the groove, the geogrid is not completely clamped and positioned at the moment, and the side wall of the movable block is gradually clung to the inclined surface of the groove after the geogrid is pulled, so that the geogrid is clamped, and therefore an operator is led to place two ends of the geogrid between the movable block and the groove of the upper clamp and the lower clamp respectively, and the two sides of the geogrid are not in a complete clamping state, so that the problem that the clamping of the upper end of the geogrid is unstable and falls is caused;
on the other hand, since the inclined surfaces of the side walls of the movable block and the grooves are gradually clung to each other by pulling the geogrid, the section of the geogrid between the movable block and the grooves needs to be long enough, otherwise, when the geogrid is pulled, the inclined surfaces of the side walls of the movable block and the grooves are not completely clung to each other, so that the geogrid falls off.
The person skilled in the art is therefore working to provide a clamping structure for testing geogrid which effectively solves the above mentioned technical problems.
