Plastic HDPE Geocell for Retaining Wall 1.1mm-1.8mm
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
In the early 1980s, the US Army Corps of engineers first used geocell and obtained a patent. The early use of this technology was to build military roads on soft soil. Today, Hengquan Geocell is not only used for foundation stability, but also for erosion control of slope and channel and construction of retaining wall.
Geocell Confinement System Characteristic
Geocell cellular confinement systems applications have many advantages. We may list these advantages as follows;
It allows the use of natural filling materials instead of expensive filling materials in the application area.
In addition to being economical, it provides more than 50% reduction in filling depth compared to classical methods. Three-dimensional cells ensure the compression of the filling material, increasing the bearing capacity and it prevents collapses. It plays an important role in increasing the hardness ratio of the structural filling and thus gains strength. Due to its structure, it provides a natural drainage structure, while at the same time it prevents the filling material from being damaged by hydraulic flows.
Laying method
① Foundation treatment
Firstly, the lower layer shall be leveled and rolled. The flatness shall not be greater than 15mm, and the compaction shall meet the design requirements. Hard protrusions such as gravel and stones are strictly prohibited on the surface.
② Laying geogrid
a. When storing and laying geogrids, avoid exposure and long-term exposure to avoid deterioration of performance.
b. It shall be laid perpendicular to the line direction, overlapped and firmly connected according to the requirements of the design drawings. The strength of the joint in the stress direction shall not be less than the design tensile strength of the material, and its lamination length shall not be less than 20cm.
c. The quality of geogrid shall meet the requirements of design drawings.
d. During construction, it is necessary to maintain continuity without deformation, wrinkling and overlap. Pay attention to tension the grid by hand to make it uniform and flat, close to the lower bearing surface, and fix it with nails and other measures.
e. For the geogrid, the long hole direction is consistent with the cross section direction of the line, and the geogrid shall be straightened and leveled. The end of the grating shall be treated according to the design.
f. After the geogrid is laid, the filler shall be filled in time at an interval of no more than 48 hours to avoid direct exposure to the sun.
③ Fill
After the grating is laid, it shall be filled in time. The filling shall be carried out according to the symmetrical principle of "two sides first and then the middle", and it is strictly prohibited to fill the middle of the embankment. The filler shall not be unloaded directly on the geogrid, but must be unloaded on the paved soil surface, and the unloading height shall not exceed 1m. All vehicles and construction machinery shall not walk directly on the paved geogrid, but only along the embankment.
④ Rolling grating
After the first layer of filler reaches the predetermined thickness and is rolled to the design density, roll the grid back for 2m, bind it to the previous layer of geogrid, manually trim and anchor, and plant 1m soil outside the rolling end to protect the grid from human damage.
⑤ The laying of one layer of geogrid shall be completed according to the above method, and the laying of other layers of geogrid shall be carried out according to the same method and steps. After the grid is laid, the upper embankment will be filled.

Application:
Functioning by filling the pores with a three-dimensional honeycomb structure, the geocell cellular confinement system offers alternative solutions to geogrid material. Working with the logic of geogrid, geocell undertakes the tasks of reinforcement of geogrids on the ground and reinforcement on retaining walls. Differently, cellular confinement systems work by filling the cellular fillings.
