Abstract
A system for draining liquid from soil is disclosed. The system includes a passive capillary drain in combination with a core for gravity flow, including a sand topdressing layer, a native soil interface, and a rootzone, a curtain traversing from the sand topdressing layer through the native soil interface to at least one tube element, the at least one tube element pulling the water out of the soil with capillary suction, and a core central to the at least one tube element that moves excess water via gravity flow with capillary suction. The elements may be installed parallel at a 3 feet center and a depth of 10 inches, and/or may be installed vertically.
Claims45
A system for draining liquid from soil, said system comprising:
- a curtain;
- at least one tube element that with passive capillary suction collects the fluid proximate to said at least one tube element, said at least one tube element draining the fluid from the soil;
- and
- a core central to said at least one tube element that moves said collected fluid with gravity from said at least one tube element and drains said collected fluid from the soil,
- wherein said curtain traverses from the soil through a native soil interface to said at least one tube element.
A passive capillary and gravity drain including a layered soil profile with a native soil interface, said drain comprising:
- a curtain;
- at least one tube element that with passive capillary suction collects the fluid proximate to said at least one tube element, said at least one tube element draining the fluid from the layered soil profile;
- and
- a core central to said at least one tube element that moves at least a portion of said collected fluid from said at least one tube element with gravity and drains said portion from the layered soil profile,
- wherein said curtain traverses the layered soil profile through the native soil interface to said at least one tube element.
A system for draining liquid from a layered soil profile, said system comprising:
- a curtain;
- at least one tube element that with passive capillary suction collects the fluid proximate to said at least one tube element, said at least one tube element draining the fluid from the layered soil profile;
- and
- a core central to said at least one tube element moves excess water with gravity flow,
- said element drops at the outlet creating a hanging water column that pulls said collected fluid from said at least one tube element and drains said collected fluid from the layered soil profile with its capillary suction, and
- wherein said curtain traverses the layered soil profile through a native soil interface to said at least one tube element.
A passive capillary and gravity drain including a layered soil profile with a native soil interface, said drain comprising:
- a curtain;
- at least one tube element that with passive capillary suction collects the fluid proximate to said at least one tube element, said at least one tube element draining the fluid from the layered soil profile;
- and
- a core central to said at least one tube element, moves excess water with gravity flow,
- said element drops to create a hanging water column that with capillary suction pulls at least a portion of said collected fluid from said at least one tube element and drains said portion from the layered soil profile, and
- wherein said curtain traverses the layered soil profile through the native soil interface to said at least one tube element.
A method of moving perched fluid in a layered soil, said method comprising:
- capturing a first plurality of the fluid in at least one core;
- and
- drawing a second plurality of the fluid into at least one tube element.
