What is a geocell?

1 Definition of geocell

Geocell is a new type of geosynthetic material, also known as geonet, cell net, etc. It is a high-strength HDPE or PP sheet that is welded or woven by ultrasonic waves to form a three-dimensional honeycomb structure. When expanded, the geocell can become a three-dimensional structure that can withstand great pressure and strain. In engineering, geocells can be used to improve the bearing capacity and stability of soil, sand and gravel and other materials, and are widely used in various fields such as roads, railways, water conservancy, and construction.

2 The role of geocells

2.1 Improve the bearing capacity

Geocells can increase the bearing capacity of soil, sand and gravel and other materials, making the foundation stronger. Due to its honeycomb structure design, it can effectively disperse pressure so that soil or sand is not easily crushed, thus improving the stability of the foundation.

2.2 Prevent landslides and collapses

During the construction of mountain roads and railways, landslides and collapses are prone to occur on slopes due to complex terrain. Geocells can improve the stability of slopes and prevent landslides and collapses. Its honeycomb structure design can effectively fix the soil and prevent soil sliding and loss.

2.3 Reduce settlement and uneven settlement

In water conservancy projects and construction projects, uneven settlement of foundations is often encountered, leading to cracking, tilting and even collapse of buildings. Geocells can improve the bearing capacity and stability of the foundation and reduce the occurrence of settlement and uneven settlement. By dispersing the pressure on the foundation, the soil is less likely to be compressed, thereby reducing the amount of foundation settlement.

2.4 Simple construction

Compared with the traditional sand cushion construction method, geocell construction is simpler and faster. Its light weight and easy folding make transportation and installation very convenient. At the same time, the large expansion area of geocells can reduce construction time and construction costs.

2.5 Materials are environmentally friendly

The main material of the geocell is high-strength HDPE or PP flat wire. These materials have good corrosion resistance, aging resistance and ultraviolet resistance, and will not cause pollution to the environment. At the same time, abandoned geocells can also be recycled and reused, complying with environmental protection requirements.

3 Applications of geocells

3.1 Highway construction

In highway construction, geocells can be used to improve the load-bearing capacity and stability of the roadbed and prevent road cracking and subsidence. At the same time, in mountainous highway construction, geocells can improve the stability of slopes and prevent landslides and collapses.

3.2 Railway construction

In railway construction, geocells can be used to improve the bearing capacity and stability of track foundations and prevent track deformation and settlement. At the same time, in mountainous railway construction, geocells can improve the stability of slopes and prevent landslides and collapses.

3.3 Water conservancy projects

In water conservancy projects, geocells can be used to improve the bearing capacity and stability of dams, reservoirs and other projects to prevent landslides and collapses. At the same time, geocells can also be used in river bank protection, flood control and rescue and other fields.

3.4 Construction projects

In construction projects, geocells can be used to improve the bearing capacity and stability of the foundation and prevent the building from cracking, tilting or even collapse. At the same time, in soft soil foundation treatment, geocells can improve the bearing capacity and stability of the foundation and reduce the occurrence of settlement and uneven settlement.

3.5 Environmental protection

In the field of environmental protection, geocells can be used in soil and water conservation, ecological restoration and other fields. It plays a role in protecting the environment by fixing soil, preventing soil erosion and ecological damage.
