Production and application of biodegradable sediment control device

摘要

An elongated web of flexible material having a covering of excelsior across a portion thereof has an elongated edge portion uncovered. The elongated covered portion is folded over upon itself a number of times, and the elongated uncovered side portion (a tail) are wound upon a roll for utilization after unrolling, as a sediment barrier, properly staked into the ground.

主权项

1. An “L” shaped ground-securable elongated biodegradable, temporary sediment control arrangement having a longitudinal axis, the elongated sediment control arrangement being comprised of;
a temporary, biodegradable, normal-to-ground arrangement of, soil-trapping, longitudinally-extending, multi-folded, elongated, excelsior treatment-material coated body portion, and a temporary, biodegradable ground parallel arrangeable, longitudinally-elongated treatment-material free tail portion, wherein both the elongated excelsior treatment-material coated body portion and the tail portion form only one single “L” shape in cross-section in their ground-secured configuration.
