About Hengquan
We have experience for more than 7 years. There are two product lines for geogrid and geocell. Factory work 24hours a day, we sold more than 100,000,000rmb last year(2020). Our customers are all over the world.
There are two common problems at the junction of old and new roads: one is that the design is not comprehensive, and there are many technical difficulties in construction; the other is that the strength of the old road is insufficient and the thickness of the reinforcement layer is thin. The use of geogrid can make up for the deficiencies in design and construction, and improve the tightness of the new and old joints. Taking a highway project as an example, the original width of the pavement is 9 m, and now it is expanded to 15 m. The pavement structure layers from top to bottom are: AC-13 asphalt concrete layer, AC-20 asphalt concrete layer, cement stabilized gravel layer, graded gravel layer. Using glass fiber geogrid material, the breaking strength is ≥50 kN/m, the breaking elongation is ≥3%, the grid size is 25.4mm×25.4mm, and the width is 5m. After the construction is completed, the line can pass smoothly, and the appearance and quality are better than the old pavement structure; compared with the replacement and graded gravel method, the use of geogrid not only reduces the cost, but also saves maintenance costs, showing good social and economic benefits.
Geogrid has large tensile strength and tensile modulus, which can realize the uniform distribution of load and stress in a large area. In the soft foundation or soil layer, the application of geogrid can reduce and disperse the concentrated stress of the upper load on the soft foundation; In the asphalt structure layer, the creep effect of asphalt can be weakened and the cracking of asphalt layer can be avoided. The mesh shape of geogrid is the same, and the shear resistance of upper particles and lower particles will not be affected. The deformation and displacement caused by load compaction can be avoided under the action of stiffness, tensile strength and mesh interlocking,
Improve particle compaction effect.
When laying geogrids, the direction of force is required to be perpendicular to the axis direction of the roadbed to ensure smoothness, tension, no bulge, and overlap according to the design width. First, use U-shaped rivets to fix, the main force direction of the grille, try to ensure that the whole length has no joints, and control the overlap width to be more than 20 cm; The overlap width should be controlled at more than 10 cm; if two or more layers of grids are used, the upper and lower layers should be staggered. After the large area is laid, adjust the straightness; try to shorten the time when the grille is exposed
After filling a layer of soil, before rolling, the grid should be tensioned again to ensure that the grid is in a state of tension and stress.

In soft soil high fill engineering, laying geogrid in the middle of 30-50 cm gravel layer can form geogrid gravel cushion and give full play to the reinforcement role of excavated geogrid. On the one hand, the geogrid has strong shear resistance, which can effectively prevent the gravel from falling into the soft foundation, and promote the grid and gravel to be embedded closely to form a stable whole. On the other hand, the geogrid will form a horizontal plane in terms of drainage, which can be used as a drainage channel. After the subgrade is formed, it can effectively reduce the soil moisture content. Third, the geogrid is laid above the soft foundation, which will produce isolation effect,
It is not only convenient for construction, but also can restrain the lateral deformation of foundation and reduce uneven settlement. Fourth, increase the shear resistance of soil and change the physical and mechanical properties of soft foundation.
