Directional boring - Wikipedia
Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig.
How to create a proposed HDD bore plan - Underground
Mar 3, 2022 · Have you ever wondered how you're going to navigate through a congested HDD jobsite? Creating a bore plan allows you to efficiently execute the pilot bore.
Explaining the Technology & Engineering of Horizontal Directional ...
Cross Bores. The biggest risk involved in HDD projects is the creation of cross bores: inadvertent intersections of buried utilities. A sewer lateral compromised by a cross bore becomes a ticking time bomb. When it eventually becomes clogged and needs cleaning, the cleaning process can result in damage to the other utility line. And if that is ...

Jun 26, 2018 · Horizontal directional drilling (HDD) is a conventional method employed by cities and construction workers to install utilities and plumbing underground. Unlike traditional underground installation, HDD does not require open trenches to complete.
Horizontal Directional Drilling vs. Auger Boring
Mar 23, 2021 · Horizontal directional drilling is the industry’s preferred trenchless method for installing buried utilities over long distances. “The distance and diameter of product midsize and large maxi-rig drills can handle, as well as the ability to steer, are the main reasons why HDD is so widely used,” said Michael.

Horizontal Directional Drilling: 7 Key Facts to Know
Sep 13, 2017 · All buried structures within 10 to 25-feet (depending on mini or maxi HDD application) of the route, should be located to avoid cross boring. While it is true that HDD takes up lesser working space, sufficient space should be provided depending upon the size of the project undertaken.
What is Horizontal Directional Drilling? - Trenchlesspedia
Mar 16, 2021 · HDD lays underground pipes or utilities by drilling a bore along the planned trajectory. There usually are three stages involved – drilling the pilot hole, reaming and laying the casing, and finally pulling the pipe into position.
Space requirements for maxi-HDD rigs can range from a 100 feet wide by 150 feet long entry plot for a 1000 ft crossing up to 200 feet wide by 300 feet long area for a crossing of 3000 or more feet.
Directional Boring: An In-Depth Guide to the Process and Services
Directional boring, also known as horizontal directional drilling (HDD), is a trenchless method used to install underground utilities, including conduits, pipes, and cables. It’s preferred for its minimal surface disruption, especially in developed or sensitive areas.
