Geocell used in channel protection
In recent years, with the rapid acceleration of the urbanization process, the problem of rigid revetments has become prominent in the ecological restoration of rivers. Although traditional rigid revetments are stable, they have damaged the ecosystem. The hardening of river channels is becoming increasingly serious. While traditional rigid revetments play a role in flood control and embankment reinforcement, they also sever the aquatic and terrestrial ecosystems, leading to a decline in the self-purification capacity of the river channels and a deterioration of the ecological environment. How to achieve the ecological restoration of river revetments has become an urgent problem to be solved at present.
Nowadays, the emergence of the flexible slope protection technology using honeycomb cellular confinement system geocell provides a brand-new solution for the ecological greening of rigid river revetments. The honeycomb cellular confinement system geocell is a three-dimensional mesh cellular structure formed by high-strength welding of polymer nano-composite alloy materials. This structure can be stretched and retracted freely. It is folded during transportation and stretched into a mesh during construction. After being unfolded, it forms a three-dimensional honeycomb grid. Loose materials such as soil, crushed stones, and concrete are filled in to form a structural body with strong lateral constraints and high stiffness.Geocell can be installed on slopes as steep as 60 degrees and on channels with flow velocities greater than 25 ft/s (7.6 m/s), depending on infill material. Angular rock is used for velocities up to 10 ft/s (3 m/s), vegetated soil up to 20 ft/s (6 m/s) and concrete for velocities greater than 20 ft/s (6 m/s).
The application of the flexible slope protection technology using honeycomb cellular confinement system geocell in the ecological greening of rigid river revetments has greatly enhanced the stability of the bank slopes and prevented soil erosion. It creates good conditions for plants to take root, promotes the rapid growth of vegetation, and realizes ecological greening. It has opened up a new way for the ecological greening of rigid river revetments and is of great significance for building an ecologically livable city. It is believed that with the continuous development and improvement of the technology, the flexible slope protection technology using honeycomb cellular confinement system geocell will play an even more important role in the field of river ecological governance, making our urban river channels regain their green vitality!
The flexible slope protection technology using honeycomb cellular confinement system geocell skillfully combines new geotechnical materials, plant measures, and river slope protection technology. On the premise of retaining the original rigid slope protection structure and ensuring the flood discharge function, it reconstructs the riverbank ecosystem and landscape. This technology stabilizes the soil through the honeycomb structure, promotes plant growth, restores the ecological functions of the riverbank, and at the same time improves the landscape effect, achieving a dual guarantee of ecology and safety, and providing a sustainable solution for river governance.
