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.
Brief Introduction of Geocell Confinement System
Geogrid is a new type of synthetic material with many technical advantages. This paper introduces the application of geogrid in soft soil foundation, filling road section, pavement construction, and backfill soil, points out the key points of construction technology, and analyzes it in combination with engineering cases. It is hoped to provide experience and reference for similar projects, improve the construction quality of highway projects, and obtain economic and social benefits.
Geogrid System Characteristic
When the external force acts on the grid unevenly, the mesh will deform due to the transverse tensile stress, which shows the restraint effect and has strong adaptability to the non-uniform distributed load. The geogrid has high friction resistance. When used as reinforcement, it can enhance the shear strength of the structural layer and improve the overall stability.
After the subgrade is leveled and compacted, the geogrid shall be laid in time and positioned according to the design requirements, and the soil shall be filled and covered in time after anchoring, so as to shorten the exposure time as much as possible. If necessary, backfill can be done at the same time as the grid is laid to improve paving efficiency. In terms of specific operation, firstly, the filler is spread on both ends, and after fixing the grid, it is gradually advanced to the middle. During the rolling operation, follow the rolling sequence of the two sides first, then the middle. The pressing wheel cannot directly contact the grille, and cannot drive on the uncompacted reinforced body. During the layer-by-layer compaction, the thickness of each layer is controlled at 20-30 cm, and indicators such as compaction and flatness are checked in time to meet the design requirements.

Application in filling section
During the subgrade filling construction, if loose filler is used, it will affect the subgrade sloping construction, cause land waste, increase the construction cost, and is not conducive to the later rolling operation. Laying Geogrid on the slope can improve the slope stability and achieve the compactness index; In the road reconstruction and expansion project, the application of geogrid can promote the close combination of old subgrade and new subgrade, improve the integrity of subgrade, ensure the uniform distribution of load and avoid the deformation caused by stress concentration.
