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.

A self-cleaning elevator flight bracket system is described for attachment to an elevator or conveyor flight for pipeline padding and backfill operations. The system is designed for bolt-on installation to padding equipment elevator flights, or cleated conveyor feeders. Built-up soil, clay, and other debris, which interfere with elevator drive mechanisms, are self-cleaned with the system. The assembly is universal to fit a variety of existing bolt patterns on elevator flight plates or feeder conveyor cleats. Flexible cables are directed to engage and remove excessive backfill material build-up. While operating padding machinery in heavy soil, or clay, material builds up in the space between the elevator flights and the elevator side wall. This leads to impeding the drive mechanism. With the use of the presently described elevator flight bracket and flexible cable or fingers, the upward movement of the elevator acts to self-clean the machinery and allows for longer operation.

A device for sorting particulate material includes a main conveyor belt, a separation screen, a graded material conveyor, and an oversize material conveyor. The separation screen is configured to separate the material into a first portion and a second portion with a larger average particle diameter than the first portion. The graded material conveyor is positioned below the separation screen to receive the first portion of the material, and the oversize material conveyor is positioned at an end of the separation screen to receive the second portion of the material.

An apparatus for backfilling a trench and, more particularly, an apparatus for laying a pipeline bed layer in a trench and for laying a pipeline bedding layer once a pipeline is laid in the trench. The apparatus comprises a multi-deck screen vibrating unit. The upper deck screen comprises finger tines or a grizzly arrangement.

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.

A ditch blade assembly includes a frame coupling opposing blades oriented in a V-shape. The blades are configured to scrape the ground or surface matter to distribute that matter into a singular channel and/or smooth the surface of the ground. A roller is included to compact the loose dirt exiting the gap between the blades. One or more weights are included to increase the down pressure on the blades. The blade angle may be adjusted with both a manual and hydraulic operating assembly.

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

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

A machine for backfilling pavement material into a trench defined within a pavement surface includes a frame defining a longitudinal axis and having at least one wheel. The frame being configured to move along the pavement surface. A hopper supported on the frame and including an inlet opening configured to receive pavement material and an outlet opening configured to discharge pavement material into the trench. The machine also includes a compactor supported on the frame and aligned with the hopper along the longitudinal axis. The compactor is configured to compact the discharged pavement material within the trench.

Provided is a microtrench fill comprising concrete, a polymer, and a colorant. Also provided is a method of using the microtrench fill to fill a microtrench in a street or walkway.
