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…

Pipe jacking is a term that describes a specific trenchless pipeline installation technique. It's also used in conjunction with other trenchless methods, such as horizontal auger boring and microtunneling, where the jacking process is used to push in a pipe into a prepared borehole.…
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. Equipment Needed for HDD As horizontal…
