A ground level primary electrical distribution system deploys terrain mounted or essentially terrain flush pipes that protect suppress ignition from fires that may occur if components fail within the pipes. The pipes can be deployed in remote and rugged terrain where overhead power lines poses fire risks from wind damage and it is impractical and disruptive to bury the electricity conducting cable or deployed along roadways or field at ground level or essentially flush with the ground to avoid excavation yet avoid the use of overhead power lines that can be subject to damage from high wind. The pipes can follow the terrain between junctions over rigid segments formed by a plurality of end-to-end coupled enclosures, while the conductors are protected within jacketing or flow through flexible insulating and isolating conduits within the more rigid pipes.

Machine, especially a padding machine, (10) for the burying of pipes, in particular arranged in a respective excavation of the ground, quali gas pipelines, oil pipelines, aqueducts, or altri, in particular for la covering of said pipe with a corresponding material, in particular un treated material, preferably screened or frantumato, comprising a main support framework (12) of the apparatus, in particular which extends according to a respective longitudinal axis of the same machine (10), a cabin (24) for housing the driver of the machine (10), such a cabin is in the form of a cabin movable with respect to said main support frame (12). Said cabin (24) for housing the driver of the machine (10) can be positioned, in corresponding vertical positions, or placed at height levels different from each other, preferably moving vertically, or perpendicularly to said ground.

A roadway access hole drill for cutting a square or rectangular access hole in a roadway having a first saw opposing a second saw and a third saw opposing a fourth saw. A method of cutting a microtrench in which the buried utility is exposed by opening a square or rectangular access hole in a roadway above the buried utility using the roadway access hole drill that is controlled by a computer system connected to an under-roadway detection unit that detects a buried utility and stops movement of the drill to avoid damaging the buried utility.

Systems and methods include a wing tool configured to be operable from work vessel(s), the wing tool including thrusters capable of fluidizing sediments from a first seabed location and moving it to a second seabed location, the second seabed location including a trench or differently shaped collection sump previously made by the wing tool and/or an extraction pump. The extraction pump operates from a second work vessel having sufficient capacity to pump fluidized sediments from the trench. Certain systems include a separation unit that separates sand from silts and clays and water from collected sediment. Systems and methods for reclamation of reservoirs, moving sand waves, for pre-trenching and/or recovering marine pipelines and cables, for removing cover from marine archaeological sites and for disposing of contaminated bottom materials in an environmentally acceptable manner.

An apparatus for installing multiple strands of hose below a surface of terrain is provided. The apparatus comprises a chassis and rotating trenching blade assemblies connected to the chassis. The trenching blade assemblies are configured to dig parallel trenches when the apparatus is pulled along the terrain. Curved hose guides are connected to the chassis in trailing positions behind the trenching blades. Each hose guide receives hose from a hose reel on reel mounts connected to the chassis and deposits the hose into a trench dug by a trenching blade assembly. Trench fillers connected to the chassis trail the hose guides. Each trench filler is aligned with a respective hose guide and comprises a number of blades configured to push soil excavated from a trench back into the trench when the apparatus is pulled along the terrain.

A dirt removal and piling machine is ideally suited for use in cleaning and piling individualized and non-uniformly shaped workpieces, preferably sugar beets but also potatoes, other tuber crops, and even with aggregate rocks for a tilting receiving station. A further aspect of the present machine includes a workpiece unloading or receiving station which can tip sideways after a dump truck unloads the workpieces and longitudinally drives therethrough. In another aspect, the machine also includes a cleaning station having rotatable rollers, an underlying dirt conveyor and a moveable dirt dumping conveyor, hopper or bucket adjacent an end of the dirt conveyor and external to the rollers. Furthermore, another aspect of the machine includes an automatic and/or robotic sampling arm which is operable to remove a tuber crop workpiece sample and automatically package the sample after the sample has moved through a cleaning station.
