The intersect method of drilling uses two drills, one at each end of the bore's design path. One of which has a magnetic source mounted on the assembly (BHA) instead of a steering tool. The magnetic source allows the rig without the magnet to determine the distance and azimuth to the source.… View Full Term

Tensile force is the stretching forces acting on the material and has two components namely, tensile stress and tensile strain. This means that the material experiencing the force is under tension and the forces are trying to stretch it. When a tensile force is applied to a material, it…
An invert level is defined as the elevation of the inside-bottom of a pipe, trench, culvert, or tunnel. It may also be considered the "floor level" of a pipe. Invert levels are essential for assessing the flow in a piping system. For example, the invert of a municipal sewer…
Hoop stress is the stress that occurs along the pipe’s circumference when pressure is applied. Hoop stress acts perpendicular to the axial direction. Hoop stresses are tensile and generated to resist the bursting effect that results from the application of pressure. Three principal…
Site investigation is an integral part of any construction project, and should be attributed as much significance as would be ascribed to any other part of the project. The risk associated with undertaking a project without adequate site investigation is monumental. It's wiser to be…

Sliplining is one of the oldest trenchless methods of rehabilitating existing underground pipelines. This technique involves inserting and installing a marginally smaller diameter carrier pipe into a larger host pipe between two predefined points. Sliplining is considered to be a type of…
Microtunneling and guided boring are often erroneously used interchangeably in the construction industry. While both these trenchless boring methods may seem identical, there are a number of key differences between the two that need to be considered when deciding which technology is…

Horizontal Auger Boring offers a streamlined approach to installing underground pipelines, conduits, and cables without the need for extensive excavation. But, like any…
There are two primary methodologies within the realm of underground construction: trenchless and cut-and-cover. Both methods have distinctive characteristics and…
Trenchless methods are efficient and environmentally sustainable options for many projects, but require careful consideration of the equipment used. To select the most…

Pipe bursting is an advanced trenchless solution designed to replace deteriorating pipes without the need for extensive excavation. By employing different techniques,…
When it comes to trenchless excavation, choosing the right trenchless boring method is crucial to the success of your project. Trenchless boring, also known as…
Horizontal directional drilling (HDD) and auger boring are two common methods of trenchless excavation used in construction projects. Both methods offer unique benefits…
Trenchless technology has revolutionized the construction industry in the past few decades. With the advent of trenchless techniques like pipe jacking and…
The inadvertent return of drilling fluid is common in horizontal directional drilling (HDD) projects, and though not harmful to the environment, inadvertent returns are…
Requirements for horizontal directional drilling (HDD) environmental planning and construction monitoring vary greatly across North America, but regulatory obligations…
Well-used drilling fluid will be full of unwanted solid content from the borehole after a drilling operation. The drilling fluid picks up all the soil and rock cuttings…
