The pneumatic float consisted of an outer perimeter tube, a floor, and a removable center tube. The 18 short tons (16 t) capacity float was 8 feet 3 inches (2.51 m) wide, 33 feet (10 m) long, 2 feet 9 inches (0.84 m) deep. [45] Solid ponton
A swing bridge (or swing span bridge) is a movable bridge that can be rotated horizontally around a vertical axis. It has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right.
Floats (also called pontoons) are airtight hollow structures, similar to pressure vessels, designed to provide buoyancy in water. Their principal applications are in watercraft hulls , aircraft floats , floating piers , pontoon rhinos , pontoon bridges , and marine engineering applications such as salvage .
A floating dock, floating pier or floating jetty is a platform or ramp supported by pontoons.It is usually joined to the shore with a gangway. The pier is usually held in place by vertical poles referred to as pilings, which are embedded in the seafloor or by anchored cables. [1]
The bridge, opened to the public on August 20, 2016, measures 430 metres (1,410 ft) in total length and 6 metres (20 ft) in width, and is suspended about 300 metres (980 ft) above the ground. [1] The bridge spans the canyon between two mountain cliffs in Zhangjiajie National Forest Park in the northwest of Hunan province.
Ship caisson at Droogdok Jan Blanken at Hellevoetsluis. A caisson is a form of lock gate.It consists of a large floating iron or steel box. This can be flooded to seat the caisson in the opening of the dock to close it, or pumped dry to float it and allow it to be towed clear of the dock.
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams , to adjust flow rates in sluices and canals , or they may be designed to stop water flow entirely as part of a levee or storm surge system.
Ch 4.4.1 The composite approach: [1]: Ch 4.4.2 Typical examples include: A concrete deck is connected to a steel beam by casting it over studs welded to the beam top surface. The concrete takes compression, and the steel carries tension and transverse shear. This system is commonly used in bridge construction. [1]: Ch 4.4.2
