Subgrade Reinforcement And Crack Prevention PP 20KN Biaxial Plastic Geogrid

Biaxial Plastic Geogrid Introduction

The process flow of biaxial tensile plastic geogrid is as follows: firstly, the plastic sheet is extruded, the thickness of the sheet is in the range of 2-8 mm, and the width is about 1.2 m. then, holes are drilled on the sheet. The holes are mostly round or rhombic, with about 40 holes in each row. After heating, they are stretched along the longitudinal direction of the sheet, and the drawing ratio is 4-8. The round hole becomes a long round hole, the rib becomes thinner, and the thickness of the node basically remains unchanged, The unidirectional grille product can be obtained after setting and cutting and winding, and the bidirectional plastic grille product can be obtained after longitudinal stretching and transverse stretching. Drawing is the key of grid production, and drawing ratio and drawing temperature are important process parameters. The drawing process is also related to the plate quality, pass and distribution, drawing mechanism, etc.

Biaxial Plastic Geogrid Application

1. Reinforced support works

The friction effect of plastic geogrid in soil is much larger than that of other reinforced members. At the same time, the grid is mat shaped, which can fully contact with soil, resulting in greater isolation and reinforcement effect. Therefore, the plastic geogrid is an ideal component of reinforced retaining wall. The reinforced retaining wall constructed by plastic geogrid can reduce the lateral pressure on the wall, thus greatly reducing the lateral deformation of the wall, making the whole reinforced retaining wall more stable and beautiful. In addition, the plastic geogrid is easier to lay and install than the geogrid, with a faster construction speed and easier to obtain the construction quality Guarantee.

2. Transition treatment between foundations with different settlement

3. 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.
