A rod for collecting water or transporting water structured to result in capillary spaces between it and other similar-shaped rods when such rods are adjacent to one another. The rod has a cross-sectional shape with one surface portion of the rod being a greater distance from the center of the rod than another surface portion of the rod. The rods can be laid together in an assembly or prefabricated into an assembly that provides an efficient, high capacity water collection and/or transportation system that is resistant to clogging.

A method of drying frac sand without heat is comprised of constructing a drainage system and placing sand on top of a perforated top layer thereon. The drainage system has multiple layers through which liquid passes to dewater sand resting thereon. At the bottom of the drainage system, perforated collection pipes, at least partially surrounded by rocks, collect and carry the liquid to a collection pond for reuse. A cellular confinement layer has sections of panels which, upon expansion, have cells filled with rocks. A woven monofilament geotextile fabric layer comprising woven monofilament geotextile fabric sheets sewn together has sized openings which allow fluid, but prevent sand from passing through the openings. The top layer comprises high density polyethylene perforated sheets welded together. A watertight liner sits below the collection pipes and the cellular confinement layer. Protective layers above and below the watertight liner prevent rocks from damaging same.

A device and a method for treating soft soil foundations, the device comprises: a drainage plate (4), a water collection well (7), and a pressurizing drainage pipe (6), the pressurizing drainage pipe (6) is connected to the bottom of the drainage plate and the bottom of the water collection well through pipelines; a pressurizing module comprises: film (12), the film (12) is impermeable and covers the soft soil foundation; a pile-loading body (13), the pile-loading body (13) is arranged on the film; air compressor (1) has a pressurizing end with a space below the film to make a soil layer of the soft soil foundation below the film under an air pressure higher than the atmospheric pressure, so that the underground water discharge process can be started.

A set of three tubular drainage units, each comprised of expanded recycled polystyrene aggregate which is gray in color, is wrapped in film which optionally compresses the drainage units radially and which impedes transmission of infra-red radiation to the aggregate when the drainage units are exposed to sunlight during shipping or storage.

A golf bunker cleaning device includes a base having an open top end and an open bottom end defining an interior open space therebetween and the base configured to be buried below a ground surface of a golf bunker without filling in the interior open space. An extension collar is configured to be removably secured over the open top end of the base to increase a height of the interior open space to above the ground surface of the golf bunker, and a lid is configured to be removably secured over either the top end of the base or over the extension collar to enclose the interior open space. The extension collar comprises a plurality of collar latches each extending to a respective free end, and the base comprises a plurality of base locking apertures configured to releasable engage the respective free end of the plurality of collar latches.

A low-profile fluid collection conduit includes an elongate outer cover having an upper portion and a lower portion generally opposite the upper portion, with the outer cover being much wider than it is tall and defining an interior volume. An elongate rigid spacer is fitted within the interior volume of the elongate outer cover, with the elongate spacer allowing the majority of the interior volume to be unfilled so as to permit the flow of fluid along and within the elongate outer cover. The collection conduit is used with a fluid-impermeable membrane as part of a landfill fluid collection and conveyance system.

Methods, apparatus, and systems involving high aspect ratio conduits are provided. These may involve a plurality of high aspect ratio leaching channels that may be spaced a predetermined distance apart from each other. The predetermined distance can facilitate backfilling of the volumes of adjacent high aspect ratio leaching channels. The backfill may be sand as well as other materials.

A channel drain for use in a fabricated surface having an exposed appearance. The channel drain includes a first body having a plurality of support surfaces, with each support surface extending from a respective body sidewall in spaced relation to a body lower wall. A plurality of inserts are insertable into the first body. Each insert includes an insert cavity sized and structured to receive a selected material having an appearance substantially identical to the exposed appearance of the fabricated surface. Each insert is supported by certain ones of the plurality of support surfaces when inserted into the first body and is sized and structured to define a gap between the pair of body sidewalls when inserted into the first body, with the gap allowing for fluid to flow therethrough toward the body lower wall.

A device and a method for treating soft soil foundations, the device comprises: a drainage plate (4), a water collection well (7), and a pressurizing drainage pipe (6), the pressurizing drainage pipe (6) is connected to the bottom of the drainage plate and the bottom of the water collection well through pipelines; a pressurizing module comprises: film (12), the film (12) is impermeable and covers the soft soil foundation; a pile-loading body (13), the pile-loading body (13) is arranged on the film; air compressor (1) has a pressurizing end with a space below the film to make a soil layer of the soft soil foundation below the film under an air pressure higher than the atmospheric pressure, so that the underground water discharge process can be started.

Protection of upland areas adjacent to a variety of water body shorelines from flooding events by combining modified drainage culverts with and hidden by natural ecosystem flood attenuation environments.
