Abstract
The invention discloses a one-way geogrid tension clamp device and a construction method thereof and relates to the technical field of geogrid tools. Steering constraint reinforcing steel bars are tightly close to side surfaces of middle clamping plates; vertical positions of the steering constraint reinforcing steel bars are same as those of the corresponding middle clamp plates; a plurality of bolt holes are uniformly formed in one irregular upper clamp plate, two rectangular middle clamp plates and one irregular lower clamp plates in length directions of the plates; the bolt holes in the clamp plates are communicated in a vertical direction; pressing bolts are arranged in the bolt holes; the bolts are in a same central distance; distances between centers of bolt holes in two end parts and an end part of a near clamp plates are identical; a top plate is arranged above the irregular upper clamp plate; a bottom plate is arranged below the irregular upper clamp plate; bolt hole groovesin which connecting bolts are arranged are formed in centers of the top plate and the bottom plate. The one-way geogrid tension clamp device is convenient, simple and feasible to manufacture and can be applied to mold testing, on-site testing and anchoring of geogrids in the field of geotechnical structure engineering, a geogrid does not slide off or be broken by a clamp, and furthermore tension testing can be carried out.
Description
technical field [0001] The invention belongs to the technical field of geogrid appliances, and in particular relates to a unidirectional geogrid tensioning fixture device and an implementation method thereof. Background technique [0002] Geogrid is divided into four categories: plastic geogrid, steel-plastic geogrid, glass fiber geogrid and polyester warp-knitted polyester geogrid. It is a widely used geosynthetic material and is often used as reinforced soil Structural reinforcement, suitable for reinforcement of various embankments and subgrades, slope protection and foundation reinforcement for permanent bearing. Compared with other geosynthetic materials, geogrid has excellent performance, such as convenient construction and transportation, shortening construction period, saving cost, reducing maintenance cost, etc. [0003] The interfacial properties of reinforcement and soil are important properties of reinforced soil. If the bending resistance of reinforcement is ig...
