Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
They manufacture cutting tools and products for wear protection, including solid carbide tools and inserts, hard material rods, and wear parts as well as products for wood and stone working. The company is the fourth-largest carbide manufacturer globally and a world leader in industrial applications such as wear protection, wood, and stone working.
A suction caisson can effectively be described as an inverted bucket that is embedded in the marine sediment.Attachment to the sea bed is achieved either through pushing or by creating a negative pressure inside the caisson skirt by pumping water out of the caisson; both of these techniques have the effect of securing the caisson into the sea bed.
Rotary die cutting is die cutting using a cylindrical die on a rotary press and may be known as a rotary die cutter or RDC. A long sheet or web of material will be fed through the press into an area known as a "station" which holds a rotary tool that will cut out shapes, make perforations or creases, or even cut the sheet or web into smaller parts.
Horse artillery—rows of limbers and caissons, each pulled by teams of six horses with three postilion riders and an escort on horseback (1933, Poland). A limber is a two-wheeled cart designed to support the trail of an artillery piece, or the stock of a field carriage such as a caisson or traveling forge, allowing it to be towed.
A boot and shoe clicker is the person who cuts the uppers for boots or shoes from a skin of leather or piece of man-made material (usually from a bulk roll). This includes all components of the upper, including linings, facings, stiffeners, reinforcements for eyelets and zip-protectors.
Underwater cutting and welding, may be necessary, though in most cases it can be avoided in new construction. Commercial diving, is used when necessary or when it is an economical alternative, when work must be done by a human operator at an underwater worksite. Hyperbaric work may be appropriate in a pressurised caisson.
A concrete saw (also known as a consaw, road saw, cut-off saw, slab saw or quick cut) is a power tool used for cutting concrete, masonry, brick, asphalt, tile, and other solid materials. There are many types ranging from small hand-held saws, chop-saw models, and big walk-behind saws or other styles, and it may be powered by gasoline, hydraulic ...
