A padding machine for moving along a side of a ditch, scooping up excavated material from the side of the ditch, and sifting the excavated material into padding material for falling in the ditch comprises a frame comprising side frame members and frame rails spaced apart from the side frame members. A screening belt is driven around pulleys supported by the frame. The screening belt comprises a screen for collecting and conveying the excavated material upwardly. The screen comprises apertures for sifting the excavated material into padding material by permitting the padding material to fall through the apertures of the screen. The screen runs over the frame rails which support the screen. A discharge conveyor is mounted to the frame beneath an upper run of the screening belt. The discharge conveyor receives the padding material passing through the screen and discharges the padding material into the ditch.

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

Machine, especially a padding machine, 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, including a main support framework of the apparatus, in particular which extends according to a respective longitudinal axis of the same machine, a cabin for housing the driver of the machine, such a cabin is in the form of a cabin movable with respect to said main support frame. Said cabin for housing the driver of the machine 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 road working machine includes an operator's station that is adapted to be occupied by an operator of the road working machine. The road working machine also includes a controller and a safety light circuit that is operatively attached to the controller. The safety light circuit includes a plurality of downwardly directed safety lights that are located so as to provide lighted egress from the operator's station.

Provided is a microtrencher having a utility avoidance system that detects objects buried under the roadway, identifies whether the buried object is a utility and determines whether the buried utility is in the path of the cutting wheel. If the buried utility is in the path of the cutting wheel, an alert is sent to the operator, the vehicle is stopped, and/or the cutting wheel is raised in relation to the roadway. Also provided is a method of using the microtrencher to cut a microtrench in a roadway and to avoid cutting a buried utility in the path of the cutting wheel.

The concepts, systems and methods described herein are directed towards a device sifting soils. The device is provided to including: a frame having open areas at top, bottom, and rear side; a plurality of wheels coupled to the frame; a first screen coupled to the frame, wherein the first screen has a grid to receive material for sifting; a vibrating unit coupled to the first screen, wherein the vibrating unit is configured to vibrate the first screen such that small objects and dirt in the material pass through the screen and the open areas of the frame and the large objects in the material fall off from the first screen at a first side of the sifting device; and a tow hitch to be coupled to a vehicle, the vehicle pulling the sifting device using the tow hitch.

Methods of reinforcing a functional component, which may include a support pole or an well casing. The methods include excavating a treatment section around the perimeter of the functional component. The methods may further comprise compacting a fill material up to a fill elevation. The methods further comprise casting a mortar mixture, including with UHPC up to an upper elevation above the ground surface. A forming structure may be implemented comprising a length that corresponds to the intended length of the UHPC pour. Another embodiment of the methods comprises installing a sealant component substantially around the perimeter of the functional component. The sealant component is structured to reciprocally move with the functional component during expansion and contraction thereof.

Provided is a microtrench fill comprising cement, a polymer, and a colorant. Also provided is a method of using the microtrench fill to fill a microtrench in a roadway.
