Description

Technical Field

[0001] The utility model relates to the technical field of geogrids, in particular to a geogrid with drainage function. Background Art

[0002] Geogrid is a major geosynthetics material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement material for reinforced soil structures or reinforcement material for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted polyester geogrids. The steel-plastic bidirectional geogrid is made of high-strength steel wire that is specially treated, and is mixed with polyethylene or polypropylene, and other additives. It is extruded to become a composite high-strength tensile strip with rough embossing on the surface. It is a high-strength reinforced geogrid. From this single strip, it is woven or sandwiched at a certain interval in the longitudinal and transverse directions, and its intersection is welded by special enhanced bonding fusion welding technology to form a reinforced geogrid. It can be used in civil engineering such as roads, railways, embankments, abutments, construction access roads, docks, revetments, flood dikes, dams, tidal flat management, freight yards, slag yards, airports, stadiums, environmentally friendly buildings, soft soil foundation reinforcement, retaining walls, slope protection and road surface resistance.

[0003] The existing patent (publication number: CN 101255686 B) is a high-strength geogrid mesh, characterized in that the grid mesh is woven from high-strength and high-modulus polyethylene fibers, the grid mesh is woven from a plurality of high-strength and high-modulus polyethylene bundles, each bundle has a plurality of strands, each strand has a plurality of filaments, each single grid of the grid mesh is a quadrilateral, and the outer layer of the grid mesh is coated with process glue. The grid mesh of the present invention has a relatively high tensile strength, high corrosion resistance, high wear resistance, low elongation, small creep, strong interlocking and biting effect on the soil, can effectively treat soft soil foundations and steep slope embankments, constrain the lateral displacement of the soil, overcome the uneven settlement of the soil, greatly enhance the bearing capacity of the foundation, and improve the overall performance of the foundation. In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: 1. The device does not have a drainage function and can only bear the load on the foundation. When the place of use needs to be drained, there is no auxiliary drainage channel, which is not convenient for drainage; 2. The device does not have the function of convenient installation. When laying and installing the device, the staff needs to use nails and soil and stone weights to fix it. The connection between the sheets needs to be manually tied and overlapped, which requires a large workload and is not convenient for daily installation and use. Utility Model Content
