A Geogrid Is Geosynthetic Material Used To Reinforce Soils And Similar Materials

Jiangsu Hanovo New Material Co.,Ltd | Updated: Mar 20, 2018

Geogrid is a geosynthetic material used to strengthen soil and similar materials. Geogrid is usually used to reinforce the retaining wall and the base or subsoil beneath the road or building. The soil is separated by tension. Compared with soil, geogrid has a strong tension. This fact allows them to transfer their power to a larger area of soil than any other situation.

Geogrid is usually made of polymer materials such as polyester, polyvinyl alcohol, polyethylene or polypropylene. They can be woven or knitted with yarns, made of material strips of heat, or produced by a pattern of rules drilled into a material sheet and then stretched into a grid.

In a sense, "cold" the development of the preparation of relatively rigid polymer materials, raised the possibility that this material can be used to reinforce the walls, slope, road foundation and the soil of the foundation soil. The main function of geogrid is reinforcement. Like many other geosynthetic materials, this area is very active, with many different products, materials, configurations, etc., which constitute the geogas market today. The key feature of all geogrid is that the openings between adjacent longitudinal and transverse ribs are called "openings", large enough to permit the penetration of soil from one side of the geogrid to the other. The ribs of some geotextiles are usually fairly rigid compared to the fabric of geotextiles. As discussed later, not only is the strength of the tendon important, but the intensity of the node is also important. The reason is that, in the case of anchorage, the soil penetration in the hole is offset by the transverse rib, and the transverse rib passes the load to the longitudinal rib through the joint point. Of course, the joint is the position where the longitudinal rib meets the transverse rib and connects. They are sometimes called "nodes".

There are three types of geogrid. The first and the original geogrid (referred to as a unit or the same type grille, or more generally referred to as "stamping and tensile geogrids") is made by Frank Brian Mercer [4] in the UK Netlon invented co., LTD., founded in 1982 by Tensar Corporation in North America. A conference in 1984 helped bring geotechnical grids into engineering design. [5] similar geotextiles made in Italy by Tenax can also be used, as are the products of new Asian manufacturers.

The second type of geogrid is a more pliable textile geogrid, which USES polyethylene coated polyester fiber bundles as reinforcing parts. They were originally developed in Britain by ICI Linear Composites LTD in the UK in the 1980s, leading to the development of textile machinery made of polyester yarn. In the process, hundreds of continuous fibers gather together to form yarns, which are woven into longitudinal and transverse ribs with large open Spaces. Before the entire device is protected by a subsequent coating, cross knitting is made by knitting or interweaving. Asphalt, latex or PVC are commonly coated materials. The geosynthetics in this group are made by many companies with various trademark products. There may be as many as 25 companies around the world producing coated yarn type polyester geogles.

The third type of geogrid is made by combining polyester or polypropylene rods or belts with a mesh of lasers or ultrasound. Two manufacturers now produce the geogrid.

Geogrid is very active not only in making new products, but also in providing important technical information to help design engineers.
