Geocells for channel and retaining wall erosion control

摘要

Geocell systems provide a simple means of increasing the flow capacity of channels or reducing erosion on slopes. Construction of the systems requires no proprietary tools or equipment. The commercial geocell components are very light and compact such that shipping costs of the components to the site are minimal. To ensure the best performance of the geocell systems, a granular fill should be used unless a "green" alternative is desired. Geocell gravity channel walls can be combined with geocell channel floors to produce very compact channels having maximum erosion control protection without the need for concrete form work. The use of geocell panels in mechanical stabilized earth (MSE) walls allows the designer an alternative to the armored appearance of masonry facing. The vegetative facing possible through the use of geocell facing softens the appearance of walls and may be more appropriate in many applications.
