100mm 150mm ASTM Standard Textured HDPE Geocell For Eroison Control Load Support

100mm 150mm ASTM Standard HDPE Textured Eroison Control Geocell Load Support

Description 

YIXING SHENZHOU Geocell is a flexible three-dimensional, honeycomb like structures made from high-density polyethylene(HDPE) strips whichare ultrasonically bonded together to form an extremely strong configuration. Lin Yuan Geocell System can be filled with a widerange of material: aggregate, concrete, sand, soil, etc.

Geocell is engineered for soil stabilization applications, it is used to help improve the performance of standard construction materials and erosion-control treatments.

HDPE Geocell Production Process

The main HDPE geocell production processes include HDPE resin sourcing, geocell formation and embossing, geocell sheet cutting, honeycomb structure punching, ultrasonic welding, physical performance testing, pacaking and loading. 

Landscape Geocell Retaining Wall Applications:

1. It can protect earth from being eroded by winds and rains before grass growing up;

2. It can keep grass seeds distributed in slope firmly, and avoid to be washed;

3. Black mat can absorb thermal energy abundantly, increase ground wet, promote seed sprout, and prolong growth term of plants;

4. The surface is tough, so wind and water stream can form plenty of eddy in the surface of the
mat, which can produce energy dissipation function;

5. Plants can form composite protection layer and endure wash with high water and fast speed;6. It can replace long-lasting slope protection materials such as concrete, pitch, block, etc., and can be used in slope protection such as road, railway, river, dam, mountain slope, etc.;7. It can reduce construction cost greatly;

8. It can prevent move of sand dunes after laying sand surface, which can improve roughness of the road surface, increase sediment of the road surface, change physical performance, and improve partial ecological environment;

9. It is applied in slope protection of road, railway, mine and municipal construction, and it can prevent water and soil loss;10. First choice of gardening, greening.

Application Method:

When infilled by compacted soil, a Cellular Confinement System (CCS) is to create a new entity with enhanced mechanical and geotechnical properties. When pressure applied to the soil contained in a CCS, it results in a lateral stress on the perimeter of the cell wall. The three-dimensional confinement area reduces the lateral movement of soil particles. the vertical load applied to contained infill lead to high stress and resistance to latera interface between cell and soil.

Constrained adjacent cell provides additional resistance filled by passive resistive load cell, while the horizontal expansion by restricting the ring of high strength. Compaction is maintained to result in long-term reinforcement.

On the jobsite, all sections of geocell are fastened together and placed directly on the surface of the subsoil or placed on the geotextile covered on the roadbed surface. the sections are stretched and expanded with stretcher. geocell extended to cover several tens of meters may consist of hundreds of individual cells, depending on the size of the section and the whole area. They are then filled with a variety of filler materials such as soil, sand, aggregate or recycled materials, and then compacted using vibration compaction.

Overall CCS can create a hard mattress to distribute the load over a wider area, reduce settlement of soft soil, improve shear resistance and load carrying capacity and reduce distortion.

Technical standards and engineering verification

my country has issued the industry standard "Geosynthetics for Railway Engineering Part 1: Geocell" (draft for comments), which specifies material properties, test methods and construction requirements. Empirical studies have shown that the shear strength of geocell reinforced crushed stone composites can be increased by more than 30 times, and it exhibits good energy dissipation capabilities under dynamic loads.
