Injury from cave-in, meaning collapse of a steep wall. Mitigation includes construction of sloped walls (sloped trench) or stepped walls (benched trench). For vertical walls, trench shoring stabilizes the walls, and trench shielding provides a barrier against collapsed material.
A dado (US and Canada, / ˈ d eɪ d oʊ /), housing (UK) or trench (Europe) is a slot or trench cut into the surface of a piece of machinable material, usually wood. When viewed in cross-section, a dado has three sides. A dado is cut across, or perpendicular to, the grain and is thus differentiated from a groove which is cut with, or parallel ...
Slurry wall construction was used in 1967–1968 to construct the "bathtub" that surrounded the foundations of most of the World Trade Center site in New York City. [4] In the 1980s, the Red Line Northwest Extension project in Boston was one of the first projects in the US to use the modern form of the technology, with hydromill trench cutters ...
Shoring is the process of temporarily supporting a building, vessel, structure, or trench with shores (props) when in danger of collapse or during repairs or alterations. Shoring comes from shore, a timber or metal prop. [1] Shoring may be vertical, angled, or horizontal.
Trenchless construction includes such construction methods as tunneling, microtunneling (MTM), horizontal directional drilling (HDD) also known as directional boring, pipe ramming (PR), pipe jacking (PJ), moling, horizontal auger boring (HAB) and other methods for the installation of pipelines and cables below the ground with minimal excavation.
The 2025 Grammy Awards are here, people! And this year, the list of A-list attendees is fully stacked, meaning the red carpet is obviously full of head-turning looks. While the night's most highly ...
For more structural construction, grooves are created along the sides and/or ends of panels, such as in tongue and groove construction. [2] Applications include roofing, siding and flooring. A groove may be through , meaning that it passes all the way through the surface and its ends are open, or stopped , meaning that one or both of the ends ...
A trencher is a piece of construction equipment used to dig trenches, especially for laying pipes or electrical cables, for installing drainage, or in preparation for trench warfare. Trenchers may range in size from walk-behind models, to attachments for a skid loader or tractor, to very heavy tracked heavy equipment.
