Geocell is a kind of 3D network structure through ultrasonic welding with long
plastic material, and it is three-dimensional network after being expanded. Sometimes
it needs to be perforated according to customer’s need. The height, welding dis-
tance, plate thickness of geocell have significant effects to the project performance of
geocell; in projects, different kinds of geocell can form bedding with different cohesion,
reinforcement strength and thickness. These bedding can be placed in required posi-
tion according to the requirements of the project so as to intensify the roadbed of the
road and railway, slope, protection, build retaining wall, etc. Width of the long strip is
the height of the geocell, and the distance between two welding lines in the same side
of the plate when the geocell is not expanded is welding distance.
