US 12,584,282 B1 · Portable, reusable, high-stability, clog-resistant, universal-application, adjustable-volume non-filtration flow regulation device and system for sedimentation control related applications

Abstract

An erosion prevention and sedimentation control flow-regulation device and system is provided for all customary applications addressed by conventional filtration devices such as check-dams (ditch check, channel or culvert), inlets (curb and ground), slope (hillside), perimeter control and settling and other ponds. The flow-regulation device and system is comprised of two components: (1) a heavy, irregular-shaped, hard-wearing, non-filtering, high-porosity fill media encapsulated in a heavy-duty, high-tensile mesh (the ‘high-porosity particle mix component’), and (2) an optional sheet-like synthetic geotextile material with limited permeability (the ‘low-permeability choker component’). The high-porosity particle mix component allows much larger flows of water through the device and system. The low-permeability choker component constricts or ‘chokes’ the flow of water into the high-porosity particle mix component. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Dependent claims

A system for water flow regulation and erosion prevention and sedimentation control comprising:

an extruded plastic mesh element forming a three dimensional tubular shape, having a first porous membrane adapted for a regulated fluid communication and forming a retention volume, said first porous membrane comprising opening diameters ranging from 0.5 mm to 5 mm;
a fill media populating the retention volume, the fill media comprising a mixture of individual natural or manmade solid particles with shapes selected from differing irregular, angular, and elongated shapes;
forming nonlinear multi-axial tortuous fluid flow pathways within the retention volume with a porosity of 20% to 40%, and sufficient weight to maintain structural integrity against hydrostatic and hydrodynamic forces;
wherein the fill media comprises particles having average diameters between 1 inch and 4 inches, with at least 75% of the particles having diameters exceeding 2 inches, wherein the fill media includes crushed concrete, and wherein the fill media provides a 4:1 volume ratio of mixed sized material to fluid flow pathways to create a tortuous path for water passage while restricting sediment.
