At the surface there are cast iron shoulder castings which turn the cables from inclined to vertical. The thrust forces from these are transferred into the sandstone bedrock via further 5 ton trachyte thrust blocks set in concrete. Each anchor pit is surmounted by a small crenelated turret, with an access cover adjacent. This allows access to ...
Every engineering drawing must have a title block. [13] [14] [15] The title block (T/B, TB) is an area of the drawing that conveys header-type information about the drawing, such as: Drawing title (hence the name "title block") Drawing number; Part number(s) Name of the design activity (corporation, government agency, etc.)
Concrete water pipe Connecting to an existing water line (white pipe) with a stainless steel tapping sleeve and valve (red). A concrete thrust block is being formed behind the new connection.
A thrust block, also known as a thrust box, is a specialised form of thrust bearing used in ships, to resist the thrust of the propeller shaft and transmit it to the hull. Early thrust boxes [ edit ]
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
A wave-dissipating concrete block is a naturally or manually interlocking concrete structure designed and employed to minimize the effects of wave action upon shores and shoreline structures, such as quays and jetties. One of the earliest designs is the Tetrapod, invented in 1950.

The thrust block partly overrides a tilted rim graben that has down-dropped about 100 m (330 ft) and moved toward the crater. Overlying this graben is a layer of breccia which is apparently the remains of an ejecta blanket that once surrounded the crater.
