The bridge used two welded steel girders, supported at each end on reinforced concrete caps poured atop stone masonry abutments; the deck was supported by welded steel floor beams and rolled steel stringers. The rigid frame supports were inclined welded steel legs resting on reinforced concrete thrust blocks.
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 ]
The arch of the bridge is supported by concrete thrust blocks embedded into sandstone foundations on either side of Parramatta River. The bridge was constructed as four arches, each made from precast concrete box sections. Each rib of blocks was erected on a falsework system supported on piles.
A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component. These drawings are linked together by a "master drawing." This "master drawing" is more commonly known as an assembly drawing.
The assembly drawing typically includes three orthographic views of the system: overall dimensions, weight and mass, identification of all the components, quantities of material, supply details, list of reference drawings, and notes. Assembly drawings detail how certain component parts are assembled. [2]
Karla is the shelter's "longest resident." For every shelter dog out there, we just know there is a human who could be their perfect match.
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.
