Description

Technical Field

[0001] The utility model relates to the technical field of geogrids, in particular to a novel three-dimensional composite geogrid. Background Art

[0002] Three-dimensional composite geogrid is a three-dimensional mesh structure product woven from materials such as fibers, minerals or polymers. It is mainly used for soil reinforcement and slope protection. Its skeleton structure can disperse the load and improve the bearing capacity of the land.

[0003] At present, the geogrids commonly used in the market are mostly single-layer mesh structure designs with poor compressive performance. When the applied load is too large, the single-layer grid cannot meet the requirements of limiting the horizontal movement of soil, seriously affecting the stability of the soil.

[0004] Therefore, there is an urgent need to provide a new three-dimensional composite geogrid with a double-layer mesh structure design. Utility Model Content

[0005] In order to overcome the shortcomings that the currently commonly used geogrids are mostly single-layer mesh structure designs, which have poor compressive performance and cannot meet the requirements of limiting horizontal soil movement when the applied load is too large, seriously affecting the stability of the soil, the utility model provides a new three-dimensional composite geogrid with a double-layer mesh structure design.

[0006] To solve the above problems, the utility model adopts the following technical solutions: a new three-dimensional composite geogrid, including a support frame, in which a square grid mesh and a diamond grid mesh are arranged in an upper and lower manner.

[0007] Furthermore, the square grid mesh and the diamond grid mesh both have a certain degree of flexibility.

[0008] Furthermore, a first connecting strip is provided at one end of the support frame, a first Velcro is provided on the front side of the first connecting strip, and a second Velcro is provided on the back side of the first connecting strip.

[0009] Furthermore, the first Velcro has a fleece surface, and the second Velcro has a hook surface.

[0010] Furthermore, a second connecting strip is provided at one end of the support frame away from the first connecting strip, a collecting strip is connected to the second connecting strip, and a protective cloth cover is sewn on the collecting strip.

[0011] Furthermore, a protective sleeve is provided on the first connecting strip.

[0012] Furthermore, a warning strip is sewn on the protective cloth cover.

[0013] Compared with the prior art, the utility model has the following technical effects: 1. By setting a double-layer design of an upper square grid mesh and a lower diamond grid mesh, the tensile strength of the grid is increased, the effect of the grid on reinforcing the soil is enhanced, and the supporting strength and tensile resistance of the geogrid are improved.

[0014] 2. Through the setting of the first Velcro and the second Velcro, the geogrid can be rolled up and stored, thereby reducing the occupied area and facilitating storage.

[0015] 3. The grille can be weighted and fixed by placing heavy objects such as stones or cement blocks into the aggregate belt to ensure that the grille is in full contact with the ground and prevent the grille from being blown up by strong winds. BRIEF DESCRIPTION OF THE DRAWINGS
