Geogrid

High-strength Biaxial plastic geogrid for road base and sub-base stabilization.
Geogrids are being manufactured from polypropylene raw materials: They are polymer-coated for high UV stability and low installation damage. We can produce products of higher tensile strength or other special applications if possible on request.

Geogrid Definition

The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height, which is made of polypropylene, polyvinyl chloride, fiber, and other macromolecular polymers by thermoplastic, woven, or molded. When used in civil engineering, called geogrid.

Types of Geogrid

1)Uniaxial plastic geogrid

The uniaxially stretched plastic geogrid is made of high molecular polymer, which is plasticized and extruded, punched, heated, and then stretched longitudinally. Uniaxially stretched plastic geogrids have extremely high tensile strength and tensile modulus.
Uniaxially stretched plastic geogrid is suitable for railways, highways, bridge abutments, port terminals, geogrid retaining walls, dam reinforcement, slope reinforcement, and other engineering fields, which can greatly improve the bearing capacity, prolong the service life, and reduce the floor space. The construction is convenient, the construction period is shortened, the cost is reduced, and the maintenance cost is greatly reduced.

Geogrid Installation Guide

1. Construction site: It is required to be compacted, level and level, and the spikes and protrusions should be removed.
2. Grid laying: On a flat and compacted site, the main force direction (longitudinal) of the installed grid should be perpendicular to the axis of the embankment. The laying should be flat, without wrinkles, and as tight as possible. It should be fixed by inserting nails and earth-rock weight. The main stress direction of the grid should be full length without joints. The connection between the panels can be tied and overlapped, and the width of the overlap is not less than 10cm. If there are more than two layers of grilles, the layers should be staggered. After a large area is laid, the straightness should be adjusted as a whole. After filling a layer of soil, before rolling, the grille should be tightened or with equipment again, and the force should be uniform so that the grille is in a state of tension and stress in the soil.
3. Selection of filler: The filler should be selected according to the design requirements. The practice has proved that frozen soil, swamp soil, domestic garbage, chalk soil, and diatomaceous earth can be used as filler. Yet, gravel soil and sand soil have stable mechanical properties and are less affected by water content, so they should be preferred. The particle size of the filler should not be greater than 15cm, and the gradation of the filler should be controlled to ensure the compaction weight.
4. Paving and compaction of fillers: After the grid is laid and positioned, it should be filled with soil in time, and the exposure time should not exceed 48 hours. The flow operation method of backfilling while laying can also be adopted. First spread the filler on both ends, fix the grille, and then push it to the middle. The order of rolling is first on both sides and then in the middle. When rolling, the pressure roller cannot contact the reinforcement, and the uncompacted reinforced body generally does not allow vehicles to drive on it, so about avoid the dislocation of the reinforcement. The layered compactness is 20-30cm. The degree of compaction must meet the design requirements, which is also the key to the success of reinforced soil engineering.
5. Waterproof and drainage measures: In reinforced soil engineering, drainage treatment must be done inside and outside the wall; foot protection should be done to prevent scouring; filtering and drainage measures should be set in the soil body, and geotextiles should be set when necessary, permeable pipe (or blind ditch). Drain the water by means of dredging, and can not be blocked, otherwise, there will be hidden dangers.
