Prefabricated vertical geotextile ditch check system
A ditch check system and methods for storm water control are provided. The ditch check system can include a velocity-restricting component of geotextile fabric with one or more porosities configured to control velocities of storm water flows for sediment control and silt retention. The velocity-restricting component can have one or more reinforcing elements to provide additional support against tearing and/or undue movement, as well as attachment points for fastening the fabric to support members. The ditch check system can further include a front water seal and a rear scour guard attached to the velocity-restricting component, and which are substantially impermeable to vertical water flow to inhibit ditch scouring and prevent the flow of storm water under the ditch check system. To facilitate transportation, installation, and assembly, one or more of the components of the ditch check system can be supplied as a pre-assembled package.
1 . A ditch check system comprising:
at least one compression tube having an elongate length and an exterior surface;
a front water seal connected to a bottom portion of the exterior surface of the at least one compression tube, the front water seal extending along at least the elongate length of the at least one compression tube and extending outwardly from the at least one compression tube to a proximal edge and to a distal edge;
a rear scour guard having a proximal edge connected to the proximal edge of the front water seal and extending rearwardly from the front water seal to a distal edge; and
a plurality of compression stakes, each compression stake having an elongate stake portion configured to penetrate into and through the at least one compression tube and into a portion of the front water seal and soil therebelow, and a compression pin extending through the compression stake substantially perpendicular to an axis of the elongate stake portion and positioned adjacent a proximal end portion of the elongate stake portion, the plurality of compression stakes being positionable at spaced locations along an upper portion of the at least one compression tube and configured to apply a downward compressive force onto the at least one compression tube sufficient to resist migration of the at least one compression tube upon impact of storm water thereagainst.
2 . The ditch check system of claim 1 , wherein the front water seal, rear scour guard, and the at least one compression tube comprise a pre-fabricated unit.
3 . The ditch check system of claim 1 , wherein the exterior surface of the at least one compression tube comprises a water permeable material.
4 . The ditch check system of claim 1 , wherein the at least one compression tube defines an interior volume configured to be substantially filled with a filler material.
5 . The ditch check system of claim 1 , further comprising a plurality of staples, the plurality of staples configured to pin portions of the front water seal and portions of the rear scour guard to the soil therebelow.
6 . The ditch check system of claim 1 , further comprising at least one vertically extending sheet of a water-permeable material integrated with the front water seal, rear scour guard, and at least one compression tube, the at least one vertically extending sheet configured to substantially filter sediment and debris displaced by storm water.
7 . The ditch check system of claim 6 , wherein the at least one vertically extending sheet comprises a plurality of release stages configured to allow flow rates of the storm water therethrough.
8 . A ditch check system comprising:
at least one vertically extending sheet of a water-permeable material configured to substantially filter sediment and debris displaced by storm water;
at least one compression tube having an elongate length and an exterior surface;
a front water seal having a proximal edge connected to a bottom portion of the exterior surface of the at least one compression tube, the front water seal extending at least the elongate length of the at least one compression tube and outwardly to a distal edge;
a rear scour guard coupled to the front water seal and extending rearwardly from the front water seal to a distal edge;
wherein the at least one vertically extending sheet of a water-permeable material is integrated with the front water seal, rear scour guard, and at least one compression tube; and
a plurality of compression stakes, each compression stake having an elongate stake portion configured to penetrate into and through the at least one compression tube and into a portion of soil therebelow and a compression pin extending normal to a proximal end portion of the elongate stake portion, the plurality of compression stakes being positionable at spaced locations along an upper portion of the at least one compression tube and configured to apply a downward compressive force onto the at least one compression tube sufficient to resist migration of the at least one compression tube upon impact of storm water thereagainst.
9 . The ditch check system of claim 8 , wherein the front water seal, rear scour guard, and the at least one compression tube comprise a pre-fabricated unit.
10 . The ditch check system of claim 8 , wherein the exterior surface of the at least one compression tube comprises a water permeable material.
11 . The ditch check system of claim 8 , wherein the at least one compression tube defines an interior volume configured to be substantially filled with a filler material.
12 . The ditch check system of claim 8 , further comprising a plurality of staples, the plurality of staples configured to pin portions of the front water seal and portions of the rear scour guard to the soil therebelow.
13 . The ditch check system of claim 8 , wherein the at least one vertically extending sheet comprises a plurality of release stages configured to allow flow rates of the storm water therethrough.
