Abstract: A bulkhead system and a method of implementing such a bulkhead system in relation to a dam are disclosed herein. In one example embodiment, such a method includes providing a plurality of bulkhead sections assembled together as a bulkhead assembly, and coupling first and second side assemblies to first and second ends of the bulkhead assembly. Further, the method includes causing a first of the bulkhead sections to receive a respective amount of ballast within an internal cavity therewithin, receiving water pressure at an upstream surface of the bulkhead assembly such that the bulkhead system is forced against the dam and substantially sealed in relation thereto, and operating to counteract the water pressure and thereby prevent or limit the flow of water past the dam, where the operating is performed at least in part by one or more brace members of the side assemblies.

Abstract: A gravity induced soil remediation system for filtering waste material from a waste stream includes an upstream trench member defining an interior area. A first distribution conduit is situated in the interior area and has an inlet in communication with the waste stream and an outlet extending downstream from the upstream trench member. The first distribution conduit has a negative elevation angle between the inlet and the outlet such that the waste stream flows downwardly therebetween by the natural force of gravity. The first distribution conduit is perforated to allow a first portion of the waste stream therein to pass therethrough. The upstream trench member includes sand and carbon filter media situated in the interior area of the upstream trench member proximate the first distribution conduit to extract waste material from the first portion of the waste stream. Subsequent downward elevation trench member are connected to the first.

Abstract: A reusable nose cone device (and related retrieval apparatus) in a hollow helical piling system having a terminal helical anchor are described. The method and system include placing or installing either (i) reinforced concrete piles in situ and/or (ii) grounding systems into the ground—without utilizing a pile driver or an auger, without deconsolidating the surrounding earth and creating spoils (as with an auger), and without unnecessary sacrifice of materials. A terminal helical anchor may be installed through the hollow center of the helical piling system into the ground. The helical anchor may be installed after the removal of the nose cone device. With the system and method, independent and accurate measurement of the anchor's torque may be made and hence complementary “load” bearing, or compression, (or “pull” resisting, or tensioning) capacity may be determined prior to filling the entire pile with reinforced wet concrete.

Abstract: A pivot drive, a pivot, a cutter drive, a cutting head, and a camera are mounted to a base, and a remote control system operates the pivot drive to pivot the cutter drive from a stored to a use position, operates the cutter drive to rotationally drive the cutting head, and operates the camera to provide images of the cutting head used to cut out blockages at lateral connections of relined pipes. The camera and the cutting head are positioned in a spaced apart relationship facing each other, with the base extending beyond the cutting head sufficiently to provide this spacing. Optionally, the camera is mounted to a trailing portion of the base and the cutter drive is mounted to a leading portion, with control lines for the pivot and cutter drives routed back past but retained separated from the cutting head to avoid damage.

Abstract: An apparatus for replacing an existing pipe. The apparatus comprises a slitter and expander which surround a wire rope. The wire rope is attached to the expander, and the expander abuts either the slitter or a separation tube disposed between the expander and slitter, such that the slitter and expander are pivotable relative to each other. The apparatus is placed in a pipe to be replaced and pulled. While being pulled, blades on the slitter slit the pipe, while a sloped surface of the expander moves the slit sections apart into surrounding soil. A replacement pipe may be pulled by a pipe putter attached to the expander. A beacon may also be disposed within the apparatus to emit a signal for locating the apparatus white underground.

Abstract: A method of installing a rock bolt is provided. A bolt hole can be formed by applying an insertion force to a drill rod and while the insertion force is being applied, applying a rotational force on the drill rod to rotate the drill rod and bore the bolt hole. A rock bolt can then be installed in the bolt hole by applying an insertion force to the rock bolt to insert the rock bolt into a bolt hole and while the insertion force is applied to the rock bolt, applying a rotational force on the rock bolt to rotate the rock bolt in the bolt hole. As the rotational force being applied to the rock bolt increases, the insertion force applied to the rock bolt can be decreased until no insertion force is being applied and the rock bolt has been torqued to a desired torque amount.

Abstract: A fresh water transportation system is disclosed that takes advantage of the buoyancy of fresh water in salt water to transport fresh water through a body of salt water. The fresh water flows from an above-water vessel through a down pipe supported on the sea bed, and through a curved pipe that redirects the fresh water flow upwardly.

Abstract: The present invention provides a water control system with the reservoir level versatility of a weir stack and the relatively easy drainage of a water control gate. Multiple stack beams constrained between two opposed guide channels create a fluid reservoir having an incrementally adjustable fluid level. Increasing or decreasing the reservoir level is a matter of adding or removing one or more stack beams. To create an opening for draining fluid from any level of the reservoir, a picker mechanism captures at least one of the stack beams. By lifting the captured stack beam, and any stack beams atop the captured stack beam, the picker mechanism opens a gate at any level of the reservoir through which fluid may flow.
