Plastic Biaxial Geogrid Mesh for Road Project in Vietnam

Solution

The customers wanted to improve the stability of the roadbed and prevent settlement when building highways on soft soil foundations. Plastic biaxial geogrid mesh is a new type of building material, which has the advantages of high strength, good toughness, light weight and long life. Plastic Biaxial Geogrids are generally considered to be stretched mesh materials with a tensile strength greater than 12kN/M. The plastic biaxial geogrid mesh is made of hot plastic after strict proportioning, extruded or stamped into a net, then quenched, and then slowly heated and stretched to make the molecular chain highly oriented along the stretching direction. Due to its high tensile orientation, the tensile strength of geogrid can be as high as 100~200MPa, and the mesh elongation is small, only about 4%~10%, which is close to the level of low carbon steel. The plastic biaxial geogrid mesh has a strong mesh structure and the ideal structural mesh material. The Plastic Biaxial Geogrid can distribute the load evenly. It strengthens the soft soil through two important mechanisms: direct tensile stress and lateral displacement of the surrounding soil. For example, the geogrid is directly placed on the soft foundation, and then supplemented with a granular base layer, which not only ensures that the aggregates and the foundation soil do not mix, but also further strengthens the occlusal effect between the mesh grid and the granular material, and the base layer has anti-corrosion properties. Tensile strength, thereby improving the bearing capacity of soft soil foundation.

Due to the high friction coefficient and strong tensile capacity of the Plastic Biaxial Geogrid, the soft soil foundation can bear a large load in a short period of time, thereby greatly speeding up the filling speed and shortening the construction period of the project. The economic value of using Plastic Biaxial Geogrid lies in: ①Reduce the requirements for filling materials. When the filling materials that meet the design requirements are far away, the nearby sandy building materials can meet the design requirements after adding auxiliary geogrids. At this time, the economic value of the geogrids is vacated: 2. Reduce the amount of filling work, After reinforcement in the filling body, the compressive strength of the filling body is greatly improved, so the slope can be appropriately steepened and the amount of filling work can be reduced; ③Reduce the cost of earthwork filling and rolling. After reinforcement, the thickness of paved soil can be increased, and the number of rolling times can be reduced, thereby reducing the cost of rolling. In a word, using Plastic Biaxial Geogrid on conditional soft soil foundation not only has wide adaptability in technical application, but also has considerable economic benefits, and has broad application prospects.

After we recommended the plastic biaxial geogrid mesh that can solve the problem of road settlement to Vietnamese customers. The customer sent us the project site photos, and based on our export experience, we recommend the geogrid with BPM 35-35 specifications to the customer. Clearly understand the needs of customers and propose perfect solutions. Arrange samples, testing and production for customers at the first time and put forward our installation guidance. We have won the trust and support of customers with our professional customized services.
