Biaxial Plastic Geogrid Introduction

Biaxial geogrid is made of high molecular polymer after extruded and laminated and punched into regular mesh before longitudinal stretching.The material on the longitudinal and transverse has great tensile strength, this kind of structure in the soil can also provide a more effectively undertake the chain and the spread of the thought system, suitable for large area of permanent bearing foundation reinforcement.

Biaxial geogrid is made of Polypropylene resin as its raw material, ,it is produced through the process of extruding, punching, heating, longitudinal stretching and transverse stretching.

Main type: 15-15KN, 20-20KN, 25-25KN, 30-30KN, 35-35KN, 40-40KN, 45-45KN, 50-50KN

Width:1-5.95 meter

Longth: 50 meters

Biaxial Plastic Geogrid Application

1. Application of Geogrid in environmental treatment

Plastic geogrid is used to control soil and water loss. It can directly cover the newly excavated exposed soil slope or weathered soft rock slope. Its function is to fix some loose soil blocks and reduce surface water erosion, so as to achieve the purpose of controlling soil and water loss. Using geogrid reinforcement to treat paddy wetland can improve the stability of subgrade, save investment and shorten the construction period. Geogrid can also be used This paper focuses on the construction procedure, construction technology and quality control of reinforced cushion to treat the soft foundation of culvert. In particular, the protection of backfilled soil slope can ensure that roads and rivers will not be blocked due to the sliding of slope soil. Vegetation can also be planted on the slope protected by grid. The root system of vegetation and grid interweave with each other to further enhance the protective effect and green the environment.

2. It is a common phenomenon that there are different settlements between road sections, and bump at abutment is the most typical engineering example. There are many ways to deal with this problem in geotechnical engineering, and geosynthetics reinforcement is considered to be a more successful new technology. Using plastic geogrid to strengthen the subgrade adjacent to the abutment can greatly improve the subgrade stiffness, significantly reduce the deformation of the subgrade, and realize the foundation with different settlement It is particularly important in the construction of high-speed railway that the transition section is set up at the junction of track subgrade and road bridge abutment, and the plastic geogrid is used to treat the subgrade, so as to gradually change the track stiffness, and ensure the safety, stability and comfort of high-speed train.

3. Other works

With the development of transportation, the requirement of railway speed is improved repeatedly. It is imperative to construct high-speed railway. The high-speed railway design uses geogrid to strengthen the foundation with good effect, low cost and can greatly shorten the construction period.
