Abstract: A method of securing optical fiber and/or innerduct/microduct 140 within a microtrench 11 by laying the optical fiber and/or innerduct/microduct 140 within a microtrench 11 and inserting a plurality of microtrench plugs 6 into the microtrench 11 above the optical fiber and/or innerduct/microduct 140 to secure the optical fiber and/or innerduct/microduct 140 in the microtrench 11 and reduce bowing of the optical fiber and/or innerduct/microduct 140 up from a bottom of the microtrench 11.

Abstract: A microtrenching system having a vacuum hose supported between a vacuum truck and a microtrencher so that the vacuum hose does not contact the roadway surface while cutting the microtrench. A method of using the microtrenching system to cut a microtrench in a roadway and vacuuming spoil from the roadway and microtrench through the supported vacuum hose into a spoil container on the vacuum truck.

Abstract: 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.

Abstract: A proofing air jet having a hollow elongated body having an air outlet and a suction inlet, the air outlet opposing the suction inlet, a pressurized air inlet into the body between the air outlet and the suction inlet, the pressurized air inlet being angled with respect to the hollow elongated body to flow pressurized air in a direction from the pressurized air inlet to the air outlet and provide a suction at the suction inlet, the air outlet having an innerduct/microduct connector for connecting to an opening of the innerduct/microduct, and the suction inlet having a string inlet configured to accept string, and the method further comprising blowing air through the pressurized air inlet into the hollow elongated body and into the innerduct/microduct, wherein the air sucks the string through the string inlet and carries the string through the hollow elongated body and through the innerduct/microduct. A plurality of the proofing air jets can be connected to a manifold.

Abstract: A method of cutting a microtrench in which the buried utility is exposed by opening an access hole in a roadway above the buried utility using a 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. Also provided is a method of drilling a substantially horizontal hole under a roadway using a horizontal drill that is controlled by a computer system connected to an under-roadway detection unit that detects a buried utility and stops movement or changes direction of the drill to avoid damaging the buried utility.

Abstract: A method of exposing a buried utility under a roadway by cutting an access hole in the roadway, vacuuming away dirt surrounding the buried utility, and spraying at least one of pressurized water or compressed air into the dirt to loosen the dirt. A vacuum device having a vacuum nozzle, a compressed air nozzle, and a pressurized water nozzle.

Abstract: 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.

Abstract: 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.

Abstract: Provided is a multifunctional reel carrier, spoil material handling container device having a first trailer or first truck bed, a first container constructed to contain spoil on the first trailer or first truck bed, at least one spoil transporting device constructed to transfer spoil from a micro trencher and deposit the spoil in the first container and constructed to transfer spoil from the first container to a fill device, and at least one reel holder constructed to hold a reel of cable and/or innerduct/microduct present on the first truck or first trailer, or present on a second trailer or second truck. Also provided is a method of using the multifunctional reel carrier, spoil material handling container device to lay cable and/or innerduct/microduct underground.

Abstract: A microtrencher having a vacuum system configured to clean spoil from a microtrench having a side shroud and a suction nozzle. 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.

Abstract: A method of cutting a microtrech in which the buried utility is exposed by opening an access hole in a roadway above the buried utility using a roadway access hole drill that rotates and vibrates the drill bit.
