A system for uncovering a trench. The system comprises several subsystems, including a work machine and a frame for providing a seal with the surface to be trenched with a saw blade contained therein. The blade is supported on a hub which is slidably movable relative to the frame by operation of a linear actuator, which may be a hydraulic cylinder or the like. The vertical location of the blade within the frame is continuously adjustable to create a deeper or shallower trench. A monitoring system is provided to monitor the vertical location from an operator station.

A mobile device for the underground laying of a flexible line, a cable, a cable-pulling empty pipe or fluid transport tube. A front vehicle has a rear support frame, a lateral ejection unit, a milling unit with a milling wheel and a drag formwork or cable laying unit following the wheel. The milling unit is connected to the front vehicle for lateral pivoting up to 25, in particular up to 20, is laterally offset towards the outside with respect to the front vehicle, and can be positioned to laterally protrude over the contour of the front vehicle, by a primary articulation or a swivel joint on the lateral ejection unit having a substantially vertical axis of rotation. The drag formwork, cable laying and cable introducing unit follows the milling unit and the cable introducing unit are also laterally pivotable about a second swivel joint.

A system for installing and labeling lay flat irrigation pipe in flooded rice and furrow irrigated fields, and a trailer for laying a roll of pipe in an irrigated field. The trailer includes a flexible hitch assembly positioned at a first end of the trailer, wherein the hitch assembly couples the trailer to a vehicle. The trailer also includes a distribution assembly positioned at a second end of the trailer, wherein the distribution assembly includes a spindle and wherein the distribution assembly couples the roll of pipe to the trailer; and a gooseneck frame including a first end coupled to the hitch assembly and a second end coupled to the distribution assembly, with an upper member between the first end and the second end of the gooseneck, wherein the upper member of the gooseneck is elevated relative to the hitch assembly. The trailer may also include offset tandem wheels with a furrow assembly to facilitate the creation of a furrow ditch and for traversing flood irrigated levees for the purposes of installing lay-flat polyethylene pipe for irrigation. The trailer may also include an adjustable telescoping hitch to adjust to various vehicle hitch heights. The system includes a labeling system for indicating the punch size needed along the pipeline during installation. A computerized hole selection plan is developed and transferred to a microprocessor device, where sensors or a global positioning system is co-locate the device so the punch label can be applied along the pipe during installation.

The invention is embodied in a construction quality control tool that allows owners and contractors to meet design plans and specifications. It saves time and costs to both parties' budgets by easily measuring pipe grading while eliminating need for surveyors on site and quickly transmitting print data in real time for third-party inspectors to prepare as-built plans. Most importantly, it ensures pipes are installed safely and accurately to prevent construction issues in the future. The preferred embodiment of the invention comprises two devices: (1) a pipe setter and (2) a remote processing and recording unit. The pipe setter is mounted inside the new pipe to be installed. The pipe setter helps the pipe installer reliably and accurately install pipe that matches the line and grade (fixed x, y z) per design plan. The remote processing and recording unit enables the construction superintendent and the third-party inspector monitoring the pipe installation in real time.

A saw blade for a sawing machine for cutting micro trenches for receiving at least one duct or cable. The saw blade includes coding elements such as holes, depressions or protrusions. The holes, depressions or protrusions form at least one code symbol representing a unique identity (ID) for the saw blade.

A method for placing at least one duct/communication cable below a road surface in an area. The area comprises a first layer and a second layer, the first layer being a road layer, such as asphalt or concrete, and the second layer being a bearing layer for the first layer and being located below the first layer. The method comprising the steps of cutting a micro trench in the area through the first layer into the second layer, placing at least one duct/communication cable in the micro trench so that that duct/communication cable is placed below the first layer, and filling the micro trench so as to restore the road surface.

A conduit guide for a conduit laying machine has an arcuate channel and at least two longitudinally spaced apart roller sets rotatably mounted in the channel. Each roller set has an upper bow roller and at least two longitudinally spaced apart lower flat rollers, each roller set having a roller gap between the upper and lower rollers. The arcuate path has a radius that is equal to or greater than a minimum bend radius for the conduit. At least one roller gap adjuster has at least one resilient biasing element that permits increasing the spacings of the roller gaps while biasing the spacings of the roller gaps toward fixed minimum spacings. The guide reduces damage and/or twisting of conduits during a conduit laying operation, especially when laying multiple conduits (e.g., triplex electrical cable) from the same conduit feed passage.
