A bridge is a structure built to span a physical obstacle without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it.
A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length.
The Japanese dry garden or Japanese rock garden, often called a Zen garden, is a distinctive style of Japanese garden. It creates a miniature stylized landscape through carefully composed arrangements of rocks, water features, moss, pruned trees and bushes, and uses gravel or sand that is raked to represent ripples in water. Zen gardens are commonly found at temples or monasteries. A Zen garden is usually relatively small, surrounded by a wall or buildings, and is usually meant to be seen while seated from a single viewpoint outside the garden, such as the porch of the hojo, the residence of the chief monk of the temple or monastery. Many, with gravel rather than grass, are only stepped into for maintenance. Classical Zen gardens were created at temples of Zen Buddhism in Kyoto during the Muromachi period. They were intended to imitate the essence of nature, not its actual appearance, and to serve as an aid for meditation.
In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics in the design of foundation elements of structures.
Japanese gardens are traditional gardens whose designs are accompanied by Japanese aesthetics and philosophical ideas, avoid artificial ornamentation, and highlight the natural landscape. Plants and worn, aged materials are generally used by Japanese garden designers to suggest a natural landscape, and to express the fragility of existence as well as time's unstoppable advance. Ancient Japanese art inspired past garden designers. Water is an important feature of many gardens, as are rocks and often gravel. Despite there being many attractive Japanese flowering plants, herbaceous flowers generally play much less of a role in Japanese gardens than in the West, though seasonally flowering shrubs and trees are important, all the more dramatic because of the contrast with the usual predominant green. Evergreen plants are "the bones of the garden" in Japan. Though a natural-seeming appearance is the aim, Japanese gardeners often shape their plants, including trees, with great rigour.
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service.
A footbridge is a bridge designed solely for pedestrians. While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic.
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as simply supported.
The Irwell Sculpture Trail is the largest public art scheme in England, commissioning regional, national and international artists. The Trail includes 28 art pieces and follows a well established 30-mile (48 km) footpath stretching from Salford Quays through Bury into Rossendale and up to the Pennines above Bacup.
The Chinese garden is a landscape garden style which has evolved over three thousand years. It includes both the vast gardens of the Chinese emperors and members of the imperial family, built for pleasure and to impress, and the more intimate gardens created by scholars, poets, former government officials, soldiers and merchants, made for reflection and escape from the outside world. They create an idealized miniature landscape, which is meant to express the harmony that should exist between man and nature.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below).
The Lapstone Zig Zag was a zig zag railway built between Emu Plains and Blaxland stations on the Main Western Line of New South Wales in Australia. Constructed between 1863 and 1865 to overcome an otherwise insurmountable climb up the eastern side of the Blue Mountains, the zig zag and associated Knapsack Viaduct, a sandstone arch viaduct, were designed by John Whitton, Engineer-in-Charge of New South Wales Government Railways, and were built by William Watkins. The zig zag was listed on the Blue Mountains local government heritage register on 27 December 1991; while the adjacent Knapsack Viaduct was listed on the New South Wales Heritage Database on 2 April 1999. The Lapstone Zig Zag was the world-first Zig Zag constructed on any main-line railway.
Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels for tilt up construction. In contrast, cast-in-place concrete is poured into site-specific forms and cured on site.
The architecture of ancient Sri Lanka displays a rich diversity, varying in form and architectural style from the Anuradhapura Kingdom through the Kingdom of Kandy (1469–1815). Sinhalese architecture also displays many ancient North Indian influences. Buddhism had a significant influence on Sri Lankan architecture after it was introduced to the island in the 3rd century BC, and ancient Sri Lankan architecture was mainly religious, with more than 25 styles of Buddhist monasteries. Significant buildings include the stupas of Jetavanaramaya and Ruwanvelisaya in the Anuradhapura kingdom and further in the Polonnaruwa Kingdom. The palace of Sigiriya is considered a masterpiece of ancient architecture and ingenuity, and the fortress in Yapahuwa and the Temple of the tooth in Kandy are also notable for their architectural qualities. Ancient Sri Lankan architecture is also significant to sustainability, notably Sigiriya which was designed as an environmentally friendly structure.
The Japanese Tea Garden in San Francisco, California, is a popular feature of Golden Gate Park, originally built as part of a sprawling World's Fair, the California Midwinter International Exposition of 1894. Though many of its attractions are still a part of the garden today, there have been changes throughout the history of the garden that have shaped it into what it is today.
The Lithgow Zig Zag is a heritage-listed former zig zag railway line built near Lithgow on the Great Western Line of New South Wales in Australia. The zig zag line operated between 1869 and 1910, to overcome an otherwise insurmountable climb and descent on the western side of the Blue Mountains. It was designed by John Whitton and built from 1863 to 1869 by Patrick Higgins as contractor. It is also known as the Great Zig Zag Railway and Reserves and Zig Zag Railway. The property is owned by Department of Planning and Infrastructure. It was added to the New South Wales State Heritage Register on 2 April 1999.
Dunedin Chinese Garden is a Chinese garden located in Dunedin, New Zealand.
The Ten Tunnels Deviation is a heritage-listed 9.2-kilometre (5.7 mi) section of the Main Western Line between Newnes Junction and Zig Zag stations in Lithgow, New South Wales, Australia. It was designed and built by the New South Wales Government Railways and built from 1 June 1908 and 16 October 1910. It is also known as Great Zig Zag Railway deviation tunnels and Bell to Zig Zag Ten Tunnel Railway Deviation. It was added to the New South Wales State Heritage Register on 2 April 1999.
The Shuangxi Park and Chinese Garden is a park and garden located in Shilin District, Taipei, Taiwan on Zhishan Road. The total area of the park is 2 hectares. Built in 1974 the southern Chinese courtyard style architecture. It features pavilions, courtyards, arch bridges, zig-zag bridges, and corridors. The landscape layout and construction was completed by Hu Guoli (胡國禮)
Eight Bridges is a design of Japanese bridge that consists of eight overlapping wooden or stone planks. Its eight-part construction was first mentioned in The Tales of Ise, written during the Heian Period, and was for many centuries a well known literary motif in Japan. Over time the motif, was incorporated into a large range of art forms: it could be found on kimonos, writing boxes, screens and porcelain, and in ukiyo-e prints and garden landscapes. The specific form of the eight-plank bridge was subsequently utilised by artists and designers around the globe, by which time it had become dislocated from its origins in The Tales of Ise and literary allusion.
