High-strength geotechnical cell

High-strength geotechnical cell

Release time: 2016-04-12 12:48
product manual
The geocell is a three-dimensional grid cell structure formed by high-strength HDPE broadband and strong welding (or riveting).
characteristic:
1. It is flexible, can be folded and transported, and can be stretched into a net shape during construction, filled with loose materials such as soil, gravel, concrete, etc., forming a structure with strong lateral restrictions and large stiffness.
2, light material, wear resistance, stable chemical properties, resistance to photooxidation, acid and alkali, suitable for different soil and desert conditions.
3. Higher lateral restraint and non-slip, anti-deformation, effectively enhance the bearing capacity of the roadbed and disperse the load.
4, change the geogrid cell height, welding distance and other geometric dimensions can meet different engineering needs.
5. Flexible expansion and small transportation volume; convenient connection and fast construction speed.
Engineering Applications:
◆ Handling half-filled roadbed
When the embankment is built on a 1: 5 slope with a natural slope on the ground, steps should be dug on the embankment base. When the width of the step is not less than 1M, when the road is constructed in stages or widened, the junction of the new and old roadbed fill slopes should be opened. For excavating steps, the width of the high-grade highway steps is generally 2M. A geogrid cell is laid on the horizontal surface of each step, and the geocell's own lateral side reinforcement effect is used to better solve the problem of uneven subsidence.
◆ Subgrade in wind and sand area
The roadbed in the wind and sand area should be mainly low embankment, and the filling height should not be less than 0.3M. Due to the low roadbed construction and heavy load professional requirements of the roadbed in the sandy area, the use of geotechnical cells can limit the loose filler. Within a limited height, the roadbed is guaranteed to have high stiffness and strength to withstand the load stress of large vehicles.
◆ Taiwan roadbed filling and reinforcement
The use of geotechnical cells can better achieve the purpose of stiffening the back of the table, sufficient friction can be generated between the geotechnical cells and the filler, which can effectively reduce the uneven settlement between the roadbed and the structure, and finally can effectively alleviate " Early impact damage of bridge abutment disease to bridge deck.
◆ Subgrade in permafrost regions
When filling a subgrade in permafrost regions, the minimum filling height should be reached to prevent muddying or lowering of the upper limit of the frozen layer, resulting in excessive settlement of the embankment. The special reinforcement effect of the facade of the geocell and the effective implementation of the overall confinement can ensure the minimum filling height in some special places to the extent of ****, and make the filling have High quality strength and stiffness.
◆ Loess wet subgrade treatment
For expressways and first-grade highways that pass through collapsible loess and better compressible loess sections, or when the allowable bearing capacity of the foundation of a high embankment is lower than the pressure of the vehicle's cooperative load and the self-weight of the embankment, the embankment should also be subjected to the bearing capacity To deal with it, the superiority of the geotechnical cell is now undoubted.
◆ Salted soil, expansive soil
Highways built with saline soil and expansive soil, first-grade highways, road shoulders and slopes are all reinforced. The facade reinforcement effect of the cell is the best one among all reinforcement materials, and it has excellent Corrosion resistance can fully meet the requirements for the construction of highways in saline soil and expansive soil.
