A non-invasive method and system for reliably locating underground pipes, particularly non-metallic pipes. The invention uses portable seismic generator to direct seismic waves into the earth at a downrange sampling location suspected to overlie a buried section of pipe. The seismic waves are imbued with a distinctive attribute, such as a predetermined frequency or digital pulse. Upon encountering the pipe, seismic waves are efficiently converted to longitudinal waves which are conducted lengthwise along the pipe to an accessible region. A receiver coupled to the accessible region is tuned to detect vibrations that carry the distinctive attribute. The receiver wirelessly transmits data indicative of the intensity of detected vibrations to a remote communicator which may be attached directly to the seismic generator. By sampling several locations in near vicinity, the most probable location of the buried pipe can be deduced.

Systems and methods are disclosed for preventing damage to underground assets caused by earth work or construction equipment and vehicles. The system includes a central data system, which has access to asset location and map data, and a GPS enabled tracking device provided in the vehicle. The system operates by comparing the real-time vehicle location to the stored asset locations, displaying the map, asset information and vehicle location to the vehicle operator and generating alerts when the vehicle breaches a perimeter around an asset. Preferably, both the central data system and the tracking unit are configured to operate together and in parallel, thereby improving the reliability of the system. In addition, the system is also specifically configured to implement various approaches for using and displaying asset location data during monitoring operations while preserving the confidentiality and security of sensitive information.

A method of using a fill mask to prevent overfill and/or spillage of a fill material from bonding to the roadway surface or staining the roadway surface during filling of a microtrench.

The present disclosure generally relates to an information system for a working machine, specifically adapted for projecting an image onto an area externally of the working machine based on construction data relating to a surrounding of the working machine. The present disclosure also relates to a corresponding method and computer program for such a working machine.

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.

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.

A work machine includes: a chassis; a backhoe assembly carried by the chassis, the backhoe assembly including: a boom pivotably linked to the chassis at a boom pivot point; a boom angle sensor associated with the boom pivot point; a stick extendably linked to the boom; a stick extension sensor associated with the stick; a bucket pivotably linked to the stick at a bucket pivot point; and a bucket angle sensor associated with the bucket pivot point. A controller coupled to the boom angle sensor, the stick extension sensor, and the bucket angle sensor is configured to: determine a boom angle of the boom; determine a stick extension of the stick; determine a bucket angle of the bucket; and output a bucket location signal corresponding to a current bucket position and a current bucket orientation, relative to the chassis, based on the determined boom angle, stick extension, and bucket angle.

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.

A working vehicle includes a vehicle main body to which a tire is mounted, an excavation member coupled to the vehicle main body on a front side of the vehicle main body and that includes an end part arranged on an outer side of the tire in a vehicle-width direction of the vehicle main body, a hydraulic cylinder arranged at a center part in the vehicle-width direction and that is to move the excavation member, a housing that houses a power transmission mechanism to transmit power to the tire, and a camera supported by a part of the vehicle main body on a lower side of the hydraulic cylinder and on an upper side of the housing and that acquires an image of a region that includes end parts on both sides of the excavation member and that is between the excavation member and the tire.

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.
