HDPE Geocell Confinement System

Soil Stabilization Subgrade Strengthen Smooth And Textured Plastic HDPE Geocell Confinement System

Brief Introduction of  Geocell Confinement System

Geocell is a net cell structure formed by high strength HDPE broadband and strong welding. It can stretch freely, shrink and fold when transporting, open and fill with earth rock or concrete material when in use, forming a structure with strong lateral restriction and large stiffness. It can be used as cushion to deal with soft foundation and increase the bearing capacity of foundation. It can also be laid on the slope to form slope protection structure. It can also be used to build retaining structure.

Geocell Confinement System Specification

The structure of work cell is divided into: ordinary type, reinforced type and high strength type
Note: 1. Other specifications, models and colors can be designed and produced according to user requirements.
2. The above technical indexes are measured data of sheet thickness of 1.2mm.
The geocell is made of a number of polyethylene plates welded together. The sheet thickness is 0.8-1.5mm, the service life is 70-100 years, and the construction environment is 70 ℃ to - 40 ℃.

Geocell Confinement System working principle

The principle of geocell is a honeycomb three-dimensional limit system, which may significantly improve the function of individual filling data in bearing in a large scope. Its principle is three-dimensional limit. Under the action of concentrated load, the active area is compressed and sunk, and the force is decomposed to both sides and transferred to the transition area, and the moderate area is transferred to the passive area. The passive area will deform and uplift

Geocell Confinement System Characteristic

The geocell is light in material, wear-resistant, strong in chemical function, resistant to light and oxygen aging, acid and alkali resistance, which is applicable to different soil and desert soil conditions. Geocell is a kind of three-dimensional reticulated cell structure, which is made of REINFORCED HDPE sheet material and highly welded. High lateral limit with anti-skid, anti deformation, effectively strengthen the bearing capacity of subgrade and evacuation load.

Application of Geocell Confinement System:

1, Treatment of half filling and half subgrade: when building embankment on the slope with natural gradient of 1:5, steps shall be excavated at the base of embankment, and the width of steps shall not be less than 1m. When widening the road by stages or reconstruction, steps shall be excavated at the junction of new and old subgrade filling slopes. The width of steps for high-grade highway is generally 2m, and geocells shall be laid on the horizontal surface of each step The reinforcement effect of its own facade can better solve the problem of uneven settlement.

2. Subgrade in windy sand area: the subgrade in windy sand area shall be mainly low embankment, and the filling height shall not be less than 0.3m. Due to the special and industrial requirements of Low Subgrade and heavy load-bearing of Subgrade in windy sand area, the use of geocell can limit the loose filler, ensure the subgrade has high stiffness and strength within the limited height, so as to bear the load stress of large vehicles.

3. Reinforcement of subgrade fill behind abutment: geocell can better realize the purpose of abutment back reinforcement. Enough friction force can be generated between geocell and filler, which can effectively reduce the uneven settlement between subgrade and structure. Finally, it can be effective and slow to solve the early impact damage of bridge deck caused by "abutment bump" disease

4. Subgrade in Permafrost Region: the minimum filling height shall be reached when filling subgrade is built in permafrost area, so as to prevent excessive settlement of embankment due to frost boiling or falling of upper limit of frozen layer. Geogrid has the effect of vertical reinforcement and effective implementation of the overall lateral limit, which can largely ensure the height of small fill in some special sections, and make the fill have high-quality strength and stiffness.

5. Treatment of loess collapsible subgrade: for expressways and class I and class I highways passing through collapsible loess and loess section with better compressibility, or when the allowable bearing capacity of high embankment foundation is lower than the pressure of vehicle cooperative load and embankment self weight, the subgrade shall be treated according to the bearing capacity requirements, and then the superiority of geocell is obvious.

6. Saline soil, expansive soil: Highway constructed by saline soil and expansive soil, highway of first class, road shoulder and slope are reinforced. The facade reinforcement effect of the cell is one of the excellent reinforcement materials, and it has excellent corrosion resistance, which can fully meet the requirements of high highway construction in saline soil and expansive soil.
