![]() The pipes are then hooked to the drill head and pulled back to the machine. Horizontal directional boring machines have been used for years placing underground utilities (gas,power,telephone,sewer, etc.) The drill enters the ground at about a 25 degree down angle, upon reaching the desired bore depth the drill can be turned to travel horizontally, upon reaching the desired bore length the drill can be turned to go back up and exit the ground. ![]() I'd plan on the directional boring depth to be an average of 10-15'. All my installs so far have been good using vertical holes and I don't want to get a bad rep if we have another serious drought and I lose heat conductivity. I have never dug a horizontal field because the soil here is mostly black-land clay and during droughts the ground has dried out to a depth of >6ft. Additionally I realize I will need to grout the hole and plan on pulling the tremie pipe along with the HX piping to make sure there are no voids. The company is willing to send a machine to a job and demo it but I'd like to get some feedback before I waste time and money. Does anyone have experience using this type of technology for geo and did it work satisfactorily? I'm leaning toward the DitchWitch JT1220 if it seems that it will work. The soils here are conducive to using a directional drill and I will be able to schedule the work better and hopefully control costs and cleanup. I am unwilling to spend two years as an apprentice driller (not that anyone would hire a worn-out HVAC business owner) just to become licensed to drill a vertical hole and thought about using a directional horizontal rig. My problem is three-fold 1) The geo drillers prices have shot up in my area, 2) None have been very reliable, 3) The rigs and crews leave a big mess for us to clean up after. I'm hoping another geo professional or informed homeowner will be able to give me some insight on their experience/success/problems/performance concerning using a directional horizontal boring rig to install the HX field. Have questions about horizontal directional drilling? Let us know! We’re here to help.Long time lurker, first time poster. Wiring is critically important in this type of work. This is done in one process by a horizontal directional drill machine and offers longevity in the piping materials. ![]() ![]() Many are using a process called “ pipe bursting” which involves breaking the current pipe and pulling a new plastic pipe inside the burst pipe as a new (and heavily enhanced) replacement. They are choosing HDD piping as a replacement because of its toughness, durability and easy wire locating abilities, which avoid serious disruption of surrounding areas. ![]() A very popular cabling system right now, many construction companies and municipalities are currently replacing old wood, concrete and cast iron pipes that were installed years ago that are leaking and rupturing. Underground locating tracer wire, stainless steel HDD wire, and steel cables for HDD piping, are a few of our specialties at Performance Wire and Cable. Made with high molecular weight and high-density polyethylene (HMWPE/HDPE) insulators, stainless steel HDD cables are great for direct burial use and are resistant to crushing, abrasion, chemicals and moisture, making it highly functional in a variety of underground environments, especially in HDD settings. Stainless steel HDD wires and cables can also be used within these systems, which boast enhanced toughness and strength. It can be ducted hundreds of feet below the surface and still be detected (with the right set-up). If the proper tracer wire is accurately installed, it will make locating of the piping extremely easy in the future. Top industries that take advantage of HDD including transportation and roadway, agriculture, sewage, telecommunication, gas and energy, and more.Īlthough sometimes overlooked, tracer wire is an extremely important component to an HDD system for accurate locating, long after the project is complete and the pipe or duct is in service. Information is transmitted through the wire to communicate with devices on the ground level. Lower costs, more environmentally friendly, and deeper and longer piping/wiring are some of the benefits to choosing this method over some traditional forms of installation. ![]()
