A transmission line is a large pipe that carries natural gas long distances across a national utility infrastructure. It is used to transport natural gas as part of a huge system of pipelines, often across state boundaries. Trenchless construction is used to install pipes in the natural gas… View Full Term

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…
A backdrop manhole is a drop shaft installed either externally or internally in a manhole in a sewer network. Backdrop manholes connect pipes of differing invert levels and allow for the pipe at a higher level to connect to the lower level pipe with minimum fall. Typically, backdrop…
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…
Pipe ramming works on the principle of soil displacement and is an excellent method for pipeline installation where ground loss is expected due to shallow depth of installation. It is a casing installation method in which a pneumatic hammer slams the casing into the ground using…

A term like sewer rehabilitation brings with it thoughts of dug up roads and sidewalks, piled up rubble, unpleasant smells, excess cost and wasted days. Traditional sewer rehabilitation work for independent houses often also meant digging up the driveway, spoiling immaculate gardens and…
While the term "trenchless" suggests the absence of trenches, there are instances where small excavations are needed during trenchless construction. These trenches, known as entry and exit pits, are openings located at the beginning and endpoints of construction operations. They…

Tunnel boring machines (TBMs) and microtunnel boring machines (MTBMs) are used to construct underground tunnels and passages with circular cross-sections. They both use a drilling mechanism, known as a cutting head, to remove material and advance the equipment forward. However, both these…
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…
