The invention discloses a one-way geogrid anchoring fixture device and an implementation method thereof, and relates to the technical field of geogrid tools. The device comprises four clamping platesand two turning constraint reinforcing bars, and the two turning constraint reinforcing bars are tightly close to the two clamping plates in the middle and flush with the corresponding clamping platesin the middle in the vertical direction; a plurality of bolt holes are equidistantly formed in the length directions of each clamping plate; when anchoring is conducted, geogrid ribs firstly penetrate through the parts between the two clamping plates in the middle and between the two turning constraint reinforcing bars, the geogrid ribs of an upward folding group are turned around the constraintribs in the upper portion for one and a half circles before penetrate through the two clamping plates in the upper portion to reach the end part of a fixture, and the geogrid ribs of a downward folding group are turned around the constraint ribs in the lower portion for one and a half circles before penetrate through the two clamping plates in the lower portion to reach the end part of the fixture. The device has the advantages of clear principle, simple construction and convenient production, the breaking and sliding moving of geogrids are prevented after clamping is conducted, and the devicecan be applied to a testing environment of geogrid anchoring and the field of geotechnical structural engineering.
Description
technical field [0001] The invention belongs to the technical field of geogrid appliances, and in particular relates to a one-way geogrid anchoring fixture device and an implementation method thereof. Background technique [0002] Geosynthetics are often used as reinforcement materials for reinforced soil structures, and geogrids are widely used as geosynthetics. Therefore, geogrids are often used for reinforcement of various embankments and roadbeds, slope protection and foundations. Reinforcement treatment. Geogrid has excellent properties such as convenient construction and transportation, shortened construction period, and low cost. [0003] Engineering practice shows that when the geogrid-reinforced soil structure reaches the ultimate bearing capacity, the deformation of the geogrid is not large, that is, the degree to which the geogrid can improve the bearing capacity of the reinforced soil structure is limited. For this reason, a certain pre-strain is applied to the...
