The present Application discloses a trenching device with two operational modes, Mode 1 and mode 2. In Mode 1, the trenching lever is disengaged, the device does not trench, but only functions as a transporting unit in a forward direction with a maximum speed. In Mode 2, the trenching lever is engaged, the device starts trenching, but stops functioning as a transporting unit.

A microtrencher having a vacuum system configured to clean spoil from a microtrench having a rotating brush. A method of using the microtrencher to cut a microtrench in a roadway and using the vacuum system to clean spoil from the roadway and microtrench.

A hydrovac with an engine compartment, cab, chassis frame and wheels, blower module, boom and a combined mud and water tank that has sliding rails, mounted to the chassis frame. The mud and water tank slide relative to the truck chassis on rails. The tanks move rearward and forward relative the truck chassis.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is “reclaimed” for use with a drilling system.

A collection tank for use in a vacuum operated earth reduction system, the collection tank comprising a closed first end, an open second end defining a tank sealing flange and a body extending between the closed first end and the open second end. An internal chamber defined by the body, the closed first end and the open second end has a door coupled to the open second end and is configured to releasably seal the open second end. An automated door closer is coupled to a center of the door, wherein the automated door closer provides a closing force at the center of the door so that the closing force is equally distributed about a periphery of the door to seal the door against the tank sealing flange.

An annulus excavation tool that would surround the decayed pole or pile and hydraulically excavate the annulus around the pole down to −2.0′ via a jetting manifold. A vacuum/tremie manifold is selectively coupled to a vacuum source to remove the soil and decayed material and creating a bonding surface for the mortar. The annulus tool would then be coupled to the mortar source and raised while a UHPC mortar would be tremied into the tool for delivery into the annulus. When the tool reaches ground level the rest of the pour is done using a Sonotube or other temporary form. This mortar encasement not only makes up for the structural deficiencies but also isolates the pole from both air and water which then kills the existing fungi and insects while also preventing any future invasion.
