Description

Technical Field

[0001] The utility model relates to the technical field of geogrids, in particular to a reinforced double-layer geogrid. Background Technique

[0002] A geogrid is an important material used in earthwork and water conservancy projects. It is mainly made of high molecular polymers (such as polyethylene or polypropylene). Geogrids usually adopt a mesh structure, similar to a grid-like form. By embedding the geogrid into the soil, the tensile strength of the soil can be effectively increased, the settlement and lateral displacement of the soil can be slowed down, and the stability of the soil can be improved. In addition, the geogrid can also increase the drainage performance of the soil and prevent water accumulation inside the soil.

[0003] In the prior art, a Chinese patent document with the application number: 201720892853.X discloses a reinforced double-layer geogrid, belonging to the technical field of building grids, including an upper-layer geogrid, a lower-layer geogrid, a geomembrane, a conical connecting rod and a nut; a geomembrane is arranged between the upper-layer geogrid and the lower-layer geogrid, and mounting holes are respectively arranged at the joints of the transverse grids and longitudinal grids of the upper-layer geogrid and the lower-layer geogrid. The conical connecting rod passes through the mounting holes and connects the upper-layer geogrid, the geomembrane and the lower-layer geogrid together through the nut; the structure of the utility model is reasonable and compact, and it is convenient to use; the upper-layer geogrid, the geomembrane and the lower-layer geogrid are connected together through the conical connecting rod and the nut, so that the original single-layer geogrid forms a geogrid structure with a double-layer structure, strengthening the stability of the geogrid. At the same time, the bottom end of the conical connecting rod adopts a conical structure, which is convenient to insert into the geological environment with poor conditions, and has the effect of further strengthening the geogrid.
