II,Product Description

Geogrids are a major geosynthetic material. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fibre geogrids and glass fibre polyester geogrids. Compared with other geosynthetics, it has unique properties and efficacy. Geogrids are commonly used as reinforcement for reinforced soil structures or as reinforcement for composite materials, etc.

A plastic geogrid is a square or rectangular polymer mesh formed by stretching, which can be unidirectional or bidirectional depending on the direction of stretching at the time of manufacture. It is made by punching holes in extruded polymer sheets (mostly made of polypropylene or high density polyethylene) and then applying directional stretching under heated conditions. The unidirectional stretch is made along the length of the sheet, while the bi-directional stretch is made by continuing to stretch the unidirectional stretch in a direction perpendicular to its length.
The polymer polymer is re-oriented during the manufacturing process by heating and stretching, which strengthens the linkage between the molecular chains and increases their strength. Its elongation is only 10% to 15% of that of the original sheet. If anti-ageing materials such as carbon black are added to the geogrid, it can be made to have better durability in terms of acid resistance, alkali resistance, corrosion resistance and ageing resistance.

Physical properties
1, Has a very strong tensile strength, tensile strength range of 25-110kn/m, depending on the product type, the tensile strength also varies.
2, Stress elongation is small, the structure has a very good side-limit stability enhancement ability.
3, High physical and chemical stability, anti-aging, soil burial, corrosion resistance.
4,Great coefficient of friction, the mesh structure is fully integrated into the soil and stone structure to enhance the stability of the structure.
5,Strong resistance to environmental stress, with a small amount of deformation in the stress enhancement, in the range of -20 ºC ~ 120 ºC temperature deformation coefficient is small.
6,The width is generally 4-6 meters, light weight, easy to install and construct, efficient and economic.

V,Product Function
1. It can be applied in all kinds of roads, railways, airports to enhance the roadbed.
2. It can be applied in a large car park and terminal freight yard, etc., to strengthen the foundations of a permanent load.
3. It can be applied in rail, road slope’s protection.
4. It can be applied to enhance the culvert.
5. It can be applied as a secondary enhancement after the uniaxial geogrid soil enhancement, further enhance the soil, prevent soil erosion.
6. It can be applied in mining, tunnel reinforcement.
VI,Product Application
Biaxial geogrids are made from polymers that are extruded, formed into panels and punched through a process followed by longitudinal and transverse stretching. The material has a high tensile strength in both the longitudinal and transverse directions, and this structure also provides a more effective force bearing and diffusion ideal for interlocking systems in the soil, and is suitable for large areas of permanent bearing foundations.
Application: Two-way geogrid is suitable for reinforcement of various embankments and road foundations, slope protection, cavity wall reinforcement, large airports, car parks, quay yards and other permanent bearing foundations.
1.Increase the bearing capacity of the road (foundation) and extend the service life of the road (foundation).

2.prevent the road (ground) surface from caving in or producing cracks, and keep the ground beautiful and neat.

3. Easy to construct, save time and effort, shorten the construction period and reduce maintenance costs.
4. Prevents cracks in culverts.
5. Enhances soil slopes and prevents soil erosion.

6. Reduce the thickness of bedding layer and save cost.
7. Support the stability of slope grass mats to green the environment.
8. Can replace metal mesh and be used for false roof mesh in underground coal mines.

VIII,Geogrid construction points

1,Construction site: compacted and flat, horizontal, clear of spikes and protrusions.
2,Grid laying: On a flat and compacted site, the main force direction (longitudinal) of the grid should be perpendicular to the direction of the embankment axis, laid flat, without wrinkles and as tight as possible. If the grating is installed in more than two layers, the seams between the layers should be staggered. After a large area has been laid, its straightness should be adjusted as a whole. When filling with a layer of soil, before rolling, the grating should be tensioned again by hand or machine, the strength should be uniform, so that the grating in the soil is taut and straight state.
3, The choice of filler: filler should be selected according to the design requirements. Practice has proved that, in addition to frozen soil, swamp soil, household rubbish, chalk, diatomaceous earth can be used as filler. However, the mechanical properties of gravel soil and sand soil are stable and very little affected by water content, so it is preferable to use them. The particle size of the filler should not be larger than 15cm, and pay attention to the control of filler gradation to ensure the compaction weight.
4,Filler paving and compaction: When the grating is laid and positioned, it should be filled and covered in time, and the bare time should not exceed 48 hours, or take the flowing operation method of backfilling while laying. Pave the fill at both ends first, fix the grating and then advance towards the middle. The order of rolling is first on both sides and then in the middle. When rolling, the roller must not be in direct contact with the reinforcement, and vehicles are not allowed to drive on the uncompacted reinforced body in order to avoid misalignment of the reinforcement. The degree of compaction in layers is 20-30cm. the degree of compaction must meet the design requirements, which is also the key to success or failure of reinforced soil projects.
5,Anti-drainage measures: in the reinforced soil project, must be good inside and outside the wall drainage treatment; to do a good job of foot protection, anti-scouring; in the soil body to set filtering, drainage measures, if necessary, should be set geotextile.
