A Geogrid sample manufactured by knitting Method-3: By Welding and Extrusion This choice varies with the manufacturer of geogrids.įig.
The product is bought into the market by giving them an additional coating of either bituminous material or a polyvinyl chloride or a latex. These materials are recommended to have high tenacity, to give the Geogrid the final desired property. In this method of Geogrid manufacture, single yarns of polyester or polypropylene material undergo either knitting or weaving to form flexible junctions forming apertures. A Geogrid manufactured from the method of extrusion Method-2: By Knitting or Weaving A figure representing an extruded Geogrid is shown below.įig. Next step involves the development of tensile strength, by stretching the material to both longitudinal and transverse direction. The punching of a pattern of holes would result in the formation of so-called apertures. Already set punching pattern is placed over the sheet to make holes for the formation of desired grids. The plastic material used may be high-density polypropylene or high-density polyethylene. This manufacturing method of geogrids involves extrusion of a flat sheet of plastic into the desired configuration. Here we are going to discuss three most used method of manufacturing of geogrids: Many manufacturing choices are available for ribs. In the case of geogrids, the strength at the junction is considered more important because the loads are transmitted from adjacent ribs through these junctions. This aperture varies from 2.5 to 15cm based on the longitudinal and transverse arrangement of the ribs.Īmong different types of geotextiles, geogrids are considered stiffer. The open space, as shown in the above figure, due to the intersection of perpendicular ribs are called as the apertures. These materials form matrix structured materials. Geogrid's rib formation in machine and cross machine directions of manufacturing process The other direction will be perpendicular to the machine direction ribs, which are called as the cross-machine direction (CMD).įig. These grids are formed by material ribs that are intersected by their manufacture in two directions: one in the machine direction (md), which is conducted in the direction of the manufacturing process. The polymeric materials like polyester, high-density polyethylene and polypropylene are the main composition of geogrids. The geosynthetic material, geogrids, are polymeric products which are formed by means of intersecting grids.

#Different types of grids software
The main services provided through utility grids are software and special equipments. Utility Grid: This is the ultimate form of the Grid, in which not only data and computation cycles are shared but software or just about any resource is shared.
Each grid node works as a data router between two communication points, providing data-caching and other facilities to speed up the communications between such points. Network Grid: A Network Grid provides fault-tolerant and high-performance communication services. For instance, persons from different companies in a virtual enterprise can work on different components of a CAD project without even disclosing their proprietary technologies. Such advanced collaboration is possible using the grid. Grid have been divided into a number of types, on the basis of their use:Ĭomputational Grid: These grids provide secure access to huge pool of shared processing power suitable for high throughput applications and computation intensive computing.ĭata Grid: Data grids provide an infrastructure to support data storage, data discovery, data handling, data publication, and data manipulation of large volumes of data actually stored in various heterogeneous databases and file systems.Ĭollaboration Grid: With the advent of Internet, there has been an increased demand for better collaboration.
