Retaining Wall Is Used To Prevent Landslides And Loaded Gravity
Geocell Confinement System
Brief Introduction of Geocell Confinement System
Geocell is a kind of three-dimensional reticulated cell structure,
which is made of REINFORCED HDPE sheet material and welded by
high-speed welding. Generally by ultrasonic needle welding. Due to
engineering needs, some holes are drilled on the diaphragm. 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 treat soft foundation and increase the
bearing capacity of foundation. It can also be laid on the slope to
form slope protection structure, and 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
The geocell can be expanded freely, transported and folded. During
construction, it can be tensioned into a net and filled with loose
materials such as soil, gravel and concrete to form a structure
with strong lateral limit and large stiffness. Geocell is a kind of
three-dimensional reticulated cell structure, which is made of
REINFORCED HDPE sheet material and highly welded. Generally by
ultrasonic needle welding.
Geocell Confinement System Construction site
In highway engineering, after the construction of geocell,
engineers observe the settlement results five times, lasting for 5
months. According to the observation results, there is only a small
amount of different settlement after setting the geocell as the
transition section in the soft foundation treatment section, which
will not affect the subgrade damage. In addition to the settlement
observation, the engineers also observed the stability of the
subgrade on site. According to the field observation, no cracks are
found at the edge and top of subgrade, which is basically
consistent with the settlement observation results.
Usage of Geocell Confinement System:
Sludge is a large and difficult subgrade with high water content.
It has large gap, high compression characteristics, high
sensitivity and low strength. Our general methods to deal with
sludge dewatering, stability, drying, adding soil and other
measures. In the reinforcement of silt subgrade, we need to use
slope protection geocell. The volume of the cofferdam needs to bear
a lot of pressure, but it is also raised, which is obviously
different from the steel bars.
The geocell for slope protection has a lot of friction and small
creep, which can affect the environment. It is suitable for various
uses and is not affected by temperature and humidity. The more
important thing is the bearing capacity of the foundation.
