Abstract
A roll-up fold-up sluice apparatus for use in separating sediment by water flow. The apparatus includes an elongate flexible mat having formed, in a central portion therein, a plurality of longitudinally spaced riffles which extend laterally with respect to the mat's long axis, and which define associated ridges and channels on the mat's upper and lower sides, respectively. The riffles are longitudinally spaced by increasing increments progressing in one longitudinal direction in the mat and are sized and shaped to accommodate a regular ridge-to-channel nesting when the mat is rolled up in that direction. A pair of flaps joined to opposite sides of the mat's central portion can be folded between folded-up positions to form the sides for the apparatus, and folded-down positions to enable rolling up.
Claims6
Unitary roll-up fold-up sluice apparatus for use in separating sediment by water flow comprising
- an elongate flexible mat having upper and lower sides,
- means distributed along a central portion in said mat forming plural longitudinally spaced riffles which extend substantially laterally with respect to the mat's long axis and between the central portion's opposed longitudinal edges, each riffle defining an elongate ridge on said upper side and an elongate channel on said lower side, said riffles being dimensioned and longitudinally spaced for accommodating a regular ridge-to-channel nesting when said mat is rolled up in one longitudinal direction relative to the mat's long axis, with the riffles being spaced longitudinally by increasing increments progressing in said one longitudinal direction along said central portion, and
- longitudinally extending flaps joined integrally with said edges for folding between upwardly extending positions to form sides in the apparatus, and outwardly extending positions to accommodate rolling up of the mat.
