1. Treatment of semi filled and semi excavated subgrade
When constructing embankments on slopes with a natural slope steeper than 1:5 on the ground, steps should be excavated at the base of the embankment, and the width of the steps should not be less than 1M. When widening highways constructed or reconstructed by stages, steps should be excavated at the junction of the fill slopes of new and old embankments. For high-grade highways, the width of the steps is generally 2M. A geocell should be laid on the horizontal surface of each layer of steps, using the reinforcement effect of the vertical limit of the geocell itself, Better solve the problem of uneven settlement.
2. Subgrade in windy and sandy areas
The roadbed in windy and sandy areas should mainly be low embankment, and the filling height should generally not be less than 0.3M. Due to the professional requirements for low embankment and heavy bearing capacity of roadbed construction in windy and sandy areas, the use of geotechnical cells can play a lateral limiting role on loose fillers, ensuring that the roadbed has high stiffness and strength within a limited height to withstand the load stress of large vehicles.
3. Subgrade filling and reinforcement at abutment back
The use of geocells can better achieve the purpose of reinforcing the abutment back. Sufficient friction can be generated between the geocell and the filler, effectively reducing the uneven settlement between the roadbed and the structure, and ultimately effectively alleviating the early impact damage of the "abutment bump" disease on the bridge deck.
4. Subgrade in permafrost regions
When constructing fill subgrade in permafrost regions, the minimum fill height should be reached to prevent excessive settlement of the embankment due to frost heave or lowering of the upper limit of the frozen layer. The unique facade reinforcement effect and effective implementation of the overall lateral confinement of the geocell can maximize the minimum fill height in certain special sections, and ensure high-quality strength and stiffness of the fill.
5. Treatment of loess collapsible subgrade
When expressways and first-class highway pass through collapsible loess and loess sections with good compressibility, or when the allowable bearing capacity of the foundation of high embankments is lower than the pressure of the vehicle load and the self weight of the embankment, the subgrade should also be treated according to the requirements of the bearing capacity. At this time, the superiority of the geotechnical cells will undoubtedly appear.
6. Saline soil, expansive soil
The expressway, first-class highway, shoulder and side slope constructed with saline soil and expansive soil all adopt reinforcement measures. The facade reinforcement effect of the cell is the most excellent one of all reinforcement materials, and it has excellent corrosion resistance, which can fully meet the requirements of building highways in saline soil and expansive soil.
