HQ1: Typical Geogrid

What is Geogrid?

Geogrid is a kind of main geosynthetics. Compared with other geosynthetics, it has unique performance and efficacy. Geogrid is often used as reinforcement of reinforced soil structure or composite material. Geogrids are divided into four categories: Plastic geogrids, steel plastic geogrids, glass fiber geogrids and glass fiber polyester geogrids.

Applications:

When geogrid is applied in high fill subgrade, the position and number of layers of geogrid shall be determined first. In the design, the main idea is to determine the layer of geogrid first, and then determine the number of layers according to the mechanical properties of geogrid. For example, in the reconstruction and expansion project of Shenyang Dalian Expressway, there are many inland river networks and most paddy fields, which is not conducive to the stability of subgrade. When using geogrid for construction, the construction party shall lay a layer of steel plastic composite belt grid 20cm below the subgrade top. At this time, the design structure and combined force of geogrid shall be designed with the longitudinal breaking load per linear meter as 60kn / M and the transverse breaking load per linear meter as 20KN / M as the control load. In the design of geogrid, we should not only ensure its sufficient strength, but also calculate the bursting strength, puncture strength, holding tensile strength, elongation, tear strength and other properties of the material. The specific project shall be determined according to the nature of engineering structure, size, use requirements, load, construction conditions and the characteristics of geosynthetics.

Construction method

Construction method of biaxial geogrid: when the biaxial geogrid is used for Subgrade and pavement, the subgrade bed shall be excavated, the sand cushion shall be set (the height difference shall not be greater than 10cm), the platform shall be rolled into a platform, and the grid shall be laid. The longitudinal axis shall be consistent with the main stress direction, with a longitudinal lap of 15-20cm and a transverse lap of 10cm. The lap joint shall be bound with plastic tape, and the laid grid shall be fixed on the ground with U-nails every 1.5-2m, The geogrid laid shall be backfilled with soil materials in time, and the number of layers of geogrid laid depends on the technical requirements.
