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.
