Mangaweka Deviation
The Mangaweka Deviation is a 7 km single track deviation of the North Island Main Trunk (NIMT) railway line in the central North Island of New Zealand, between the settlements of Mangaweka and Utiku, south of Taihape. Opened on 18 November 1981, by the Prime Minister, Robert Muldoon, it was constructed between 1973 and 1981 at a cost of $17m; to move the line away from geologically unstable land; and also to replace the high-maintenance steel viaducts including the Mangaweka Viaduct. It is the most recent and most significant deviation of the NIMT since it was opened in 1909. History The original section of the line was constructed as part of the NIMT in 1904. The entirety of the route from Marton north to Taihape was built to the west of the Rangitikei River and lies predominantly on the terraces within the river valley. Only south of Marton does the NIMT cross the Rangitikei en route to Palmerston North and Wellington. Between the settlements of Mangaweka and Utiku ...

North Island Main Trunk Railway
The North Island Main Trunk (NIMT) is the main railway line in the North Island of New Zealand, connecting the capital city Wellington with the country's largest city, Auckland. The line is long, built to the New Zealand rail gauge of and serves the large cities of Palmerston North and Hamilton. Most of the NIMT is single track with frequent passing loops, but has double track - * between Wellington and Waikanae, except for of single-track through tunnels between North Junction ( from Wellington) and South Junction, ( from Wellington), on the Pukerua Bay to Paekakariki section, * between Hamilton and Te Kauwhata (except for the single-track Waikato River Bridge at Ngāruawāhia), and * between Meremere and Auckland Britomart. Around (approximately 65%) of the line is electrified in three separate sections: one section at 1600 V DC between Wellington and Waikanae, and two sections at 25 kV AC: between Palmerston North and Te Rapa (Hamilton) and between Papakura and ...

New Zealand State Highway 1
State Highway 1 (SH 1) is the longest and most significant road in the New Zealand road network, running the length of both main islands. It appears on road maps as SH 1 and on road signs as a white number 1 on a red shield, but it has the official designations SH 1N in the North Island, SH 1S in the South Island. SH 1 is long, in the North Island and in the South Island. Since 2010 new roads have reduced the length from . For the majority of its length it is a two-lane single carriageway, with at-grade intersections and property accesses, in both rural and urban areas. These sections have some passing lanes. Around of SH 1 is of motorway or expressway standard : in the North Island and in the South Island. Route North Island (SH 1N) SH 1 starts at Cape Reinga, at the northwestern tip of the Aupouri Peninsula, and since April 2010 has been sealed (mainly with either chipseal or asphalt) for its entire length. From Waitiki Landing south of Cape Reinga, SH 1 tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Lines In New Zealand
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Mangaweka Railway Station
Mangaweka railway station was a station on the North Island Main Trunk, serving the village of Mangaweka in the Manawatū-Whanganui region of New Zealand. The original station opened in 1902 and closed on 15 November 1981. A new station then opened to the east, on the Mangaweka deviation on 18 November 1981, though only for parcels, small lots, and as a passing loop, which still remains. The station was important as the terminus of the line from Wellington from 1902 to 1904. History An advert for timber for the station building was placed on 13 December 1901. Dates from 3 July to 30 August 1902 are mentioned for opening goods traffic to Mangaweka and 30 October for inspection of the line from Mangaonoho to Mangaweka. New Zealand Railways (NZR) took the line over from the Public Works Department on Monday, 3 November 1902, when the stationmaster was transferred from Ōhingaiti to Mangaweka and the station was noted as having a passenger platform, 84 wagon passing loop, pr ...

Track Bed
The track bed or trackbed is the groundwork onto which a railway track is laid. Trackbeds of disused railways are sometimes used for recreational paths or new light rail links. According to Network Rail, the trackbed is the layers of ballast and sub-ballast above a prepared subgrade/formation (see diagram). It is designed primarily to reduce the stress on the subgrade. Other definitions include the surface of the ballast on which the track is laid,, p. 386. the area left after a track has been dismantled and the ballast removed or the track formation beneath the ballast and above the natural ground. The trackbed can significantly influence the performance of the track, especially ride quality of passenger services. See also * Embankment (transportation) A road, railway line, or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain, the alternatives being either to have an ...

Kawhatau River
The Kawhātau River is a river of about in the southwestern North Island of New Zealand. Its source is in the Ruahine Range and its outflow is into the larger Rangitīkei River, which it meets close to Mangaweka. It was given the official name of Kawhātau River in 2020. It is joined by the Pourangaki River at Upper Kawhātau. Geology Like other parts of the Rangitīkei River system, the Kawhātau has been incised into the soft Quaternary, 3.5 to 1.7 million year old marine mudstones and sandstones, as the land has risen since the last ice age. A large proportion of the sediment in the Rangitīkei comes from the Kawhātau. Gravel has long been taken from the river. History Māori skeletons and moa bones were discovered near the river when the bush was being burnt. Felling of bush in the valley was first begun by 12 settlers from Timaru on in 1895. At that time the only access was by a cage suspended on a wire rope across the Rangitīkei from Mangaweka (then calle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formwork
Formwork is molds into which concrete or similar materials are either precast or cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated into the final structure, adding insulation or helping reinforce the finished structure. Types Formwork may be made of wood, metal, plastic, or composite materials: #''Traditional timber formwork''. The formwork is built on site out of timber and plywood or moisture-resistant particleboard. It is easy to produce but time-consuming for larger structures, and the plywood facing has a relatively short lifespan. It is still used extensively where the labour costs are lower than the costs for procuring reusable formwork. It is also the most flexible type of formwork, so even where other systems are in use, complicated sections may use it. #''Engineered Formwork System''. This formwork is built out of prefabricated modules with a me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falsework
Falsework consists of temporary structures used in construction to support a permanent structure until its construction is sufficiently advanced to support itself. For arches, this is specifically called centering. Falsework includes temporary support structures for formwork used to mold concreteHardie G.M. (1995) Building Construction: Principles, Practices, and Materials. New Jersey: Prentice Hall. (Pg 116, paragraph 1) in the construction of buildings, bridges, and elevated roadways. The British Standards of practice for falsework, BS 5975:2008, defines falsework as "Any temporary structure used to support a permanent structure while it is not self-supporting." History Falsework has been employed in bridge and viaduct construction since ancient times. The Romans were renowned for its use, as at the Limyra Bridge in Turkey. Until the turn of the 20th century almost all falsework was constructed from timber. To compensate for timber shortages in different regions and to ra ...

Ministry Of Works And Development
The New Zealand Ministry of Works and Development, formerly the Department of Public Works and often referred to as the Public Works Department or PWD, was founded in 1876 and disestablished and privatised in 1988. The Ministry had its own Cabinet-level responsible minister, the Minister of Works or Minister of Public Works. Historically, the state has played an important part in developing the New Zealand economy. For many years the Public Works Department (which became the Ministry of Works in 1948 and the Ministry of Works and Development in 1974) undertook most major construction work in New Zealand, including roads, railways and power stations. After the reform of the state sector, beginning in 1984, the ministry disappeared and its remnants now have to compete for government work. The Ministry of Works and Development was disestablished in 1988 and a Residual Management Unit continued to oversee the Ministry's operations and assets until formally ending in 1993. It was a ...

Rangitīkei River
The Rangitīkei River is one of New Zealand's longest rivers, long. Its headwaters are to the southeast of Lake Taupō in the Kaimanawa Ranges. It flows from the Central Plateau south past Taihape, Mangaweka, Hunterville, Marton, and Bulls, to the South Taranaki Bight at Tangimoana, southeast of Whanganui. The river gives its name to the surrounding Rangitikei District. In 1897 the river flooded and all the bridges over it (Vinegar Hill, Onepuhi, Kakariki railway bridge and Bulls) were damaged or destroyed. Port of Rangitikei, at the mouth of the river was also washed away and never rebuilt. Other notable floods were in 1882, 1917, 1936, 1958, 1965 and 2004. Until 1908 a ferry linked Tangimoana to Scotts Ferry. Onepuhi, or Onepuehu, bridge was shown on the 1941 map, but missing from the 1968 and later maps. Further decking for the long Onepuhi bridge was suggested in 1958. The river is a popular leisure and recreation area for jetboating, white water rafting, kayakin ...

South Rangitikei Viaduct
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

The 549m Mangaweka, Or Pouwhakaroa Tunnel Is At The Southern End Of The Mangaweka Deviation
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...
