 Principles and construction of high-strength construction measures Geocell

Geocell emergence of high-strength, breaking the previous state of the two-dimensional plane reinforced mesh material of history, its elastomeric properties of the layered state is a state of three-dimensional objects reflect a fundamental change in conjunction with morphological soil occurred, it combines state of the three-dimensional network structure and the soil is more integration and closer. Impact on a greater proportion of reinforced soil range, but also more stable and effective application of major significance in the field of engineering. First, from the characteristics of Geocell, works analyzes the feasibility of Geocell application on the highway, and put forward concrete construction method Geocell.
Geocell is a high-strength polyethylene sheet, connected by ultrasonic welding method, three-dimensional honeycomb lattice structure of the material was later expanded, is special geosynthetics. In rock engineering and soil, sand, stone and other fillers constitute Depending cohesion, different strength reinforced cushion at different depths. The cushion can be placed in position in accordance with the requirements of the project needs to reinforce the roadbed, road slope protection, construction of retaining walls. Its biggest feature is the variety of difficult problems can be done in conventional rock engineering methods are difficult to deal with, such as the bridge jumping, soft ground subsidence, Frothing, landslides and so on. With a light weight, wear resistance, aging resistance, chemical resistance, wide temperature range, high tensile strength, stiffness, toughness, impact resistance, dimensional relatively stable, easy to transport and so on. The connection is simple in construction, the construction method is simple, thus simplifying the construction process, improve the speed of construction; and can be used repeatedly. Sand sand roadbed subgrade areas should be mainly low embankment, filling height in general should not be less than 0.3m. Due to the low sand roadbed subgrade construction and heavy carrying professional requirements, the use of Geocell loose filler can play the role of confinement, in a limited high level of protection embankment with high stiffness and strength to withstand the load stress of large vehicles .
