A manhole ( utility hole , maintenance hole , or sewer hole ) is an opening to a confined space such as a shaft , utility vault , or large vessel . Manholes, typically protected by a manhole cover , are often used as an access point for an underground public utility , allowing inspection, maintenance, and system upgrades. The majority of underground services have manholes, including water , sewers , telephone , electricity , storm drains , district heating , and gas .

86-540: Manholes are generally found in urban areas, in streets and occasionally under sidewalks . In rural and undeveloped areas, services such as telephone and electricity are usually carried on utility poles or even pylons rather than underground. In Australia, manhole also commonly refers to an access hatch used to get access from a room or hallway into the ceiling cavity of a building. These manholes are typically around 450 mm × 450 mm (18 in × 18 in) square. Manhole closings are protected by

172-546: A curb . There may also be a planted strip between the sidewalk and the roadway and between the roadway and the adjacent land. In some places, the same term may also be used for a paved path, trail or footpath that is not next to a road, such as a path through a park . The term "sidewalk" is preferred in most of the USA & Canada . The term "pavement" is more common in the United Kingdom and other members of

258-478: A grating or manhole cover , a flat plug designed to prevent accidental or unauthorized access to the manhole. These covers are traditionally made of metal, but may be constructed from precast concrete , glass reinforced plastic or other composite materials (especially where cover theft is of concern). Because of legislation restricting acceptable manual handling weights, Europe has seen a move toward lighter-weight composite manhole cover materials, which also have

344-606: A "Commonwealth of Nations". Conferences of British and colonial prime ministers occurred periodically from the first one in 1887 , leading to the creation of the Imperial Conferences in 1911. The Commonwealth developed from the imperial conferences. A specific proposal was presented by Jan Smuts in 1917 when he coined the term "the British Commonwealth of Nations" and envisioned the "future constitutional relations and readjustments in essence" at

430-601: A Commonwealth country affords benefits in some member countries, particularly in the United Kingdom , and Commonwealth countries are represented to one another by high commissions rather than embassies. The Commonwealth Charter defines their shared values of democracy , human rights and the rule of law , as promoted by the quadrennial Commonwealth Games . A majority of Commonwealth countries are small states , with small island developing states constituting almost half its membership. Queen Elizabeth II , in her address to Canada on Dominion Day in 1959, pointed out that

516-540: A combined gross domestic product of over $ 9 trillion, 78% of which is accounted for by the four largest economies: India ($ 3.737 trillion), United Kingdom ($ 3.124 trillion), Canada ($ 1.652 trillion), and Australia ($ 1.379 trillion). In 1997 the Commonwealth Heads of Government agreed that, to become a member of the Commonwealth, an applicant country should, as a rule, have had

602-638: A former colony of the United Kingdom, but some have links to other countries, either exclusively or more directly (e.g., Bangladesh to Pakistan, Samoa to New Zealand, Papua New Guinea to Australia, and Singapore to Malaysia). Mozambique, in 1995, was the first country to join without such a constitutional connection, leading to the Edinburgh Declaration and the current membership guidelines. In 2009, Rwanda, formerly under Belgian and German rule, joined. Consideration for Rwanda's admission

688-455: A fundamental founding document of the organisation, laid out that membership required dominionhood. The 1949 London Declaration ended this, allowing republican and indigenous monarchic members on the condition that they recognised King George VI as " Head of the Commonwealth ". In the wake of the wave of decolonisation in the 1960s, these constitutional principles were augmented by political, economic, and social principles. The first of these

774-528: A manhole before placement. In these manholes, the entire underground enclosure is constructed of some composite material, in addition to the cover. Structures that can be integrated into composite manholes include: In urban areas, stray voltage issues have become a significant concern for utilities. On January 16, 2004, Jodie S. Lane was electrocuted after stepping on a metal manhole cover, while walking her two dogs in New York City. The location of

860-456: A report on potential amendments was presented by the Committee on Commonwealth Membership at the 2007 Commonwealth Heads of Government Meeting . New members were not admitted at this meeting, though applications for admission were considered at the 2009 CHOGM . New members must "as a general rule" have a direct constitutional link to an existing member. In most cases, this is due to being

946-735: A republic in January 1950, it would remain in the Commonwealth and accept the British Sovereign as a "symbol of the free association of its independent member nations and as such the Head of the Commonwealth". Upon hearing this, King George VI told Menon : "So, I've become 'as such'". Some other Commonwealth countries that have since become republics have chosen to leave, whilst others, such as Guyana , Mauritius and Dominica , have remained members. India's inaugural prime minister Jawaharlal Nehru declared on 16 May 1949, shortly following

1032-720: A republic in accordance with the Irish Republic of Ireland Act 1948 ; in doing so, it also formally left the Commonwealth. Whilst Ireland had not actively participated in the Commonwealth since the early 1930s, other dominions wished to become republics without losing Commonwealth ties. The issue came to a head in April 1949 at a Commonwealth prime ministers' meeting in London . Under the London Declaration , as drafted by V. K. Krishna Menon , India agreed, when it became

1118-480: A road. " Shared use paths " or "multi-use paths" are available for use by both pedestrians and bicyclists. " Walkway " is a more comprehensive term that includes stairs, ramps, passageways, and related structures that facilitate the use of a path as well as the sidewalk. In the UK, the term " footpath " is mostly used for paths that do not abut a roadway. The term "shared-use path" is used where cyclists are also able to use

1204-456: A sewer manhole must be carefully considered to ensure that the drainage system is effective and easy to maintain . According to design standards, the distance between two manholes is typically between 7 and 20 meters, depending on the specific characteristics of the project. In cities, the distance is 20 meters per manhole, while in industrial or commercial settings it is 10-15 meters per manhole. The distance between manholes in homes or restaurants

1290-444: A tax from 1766. Another turning point was the construction of Paris's Pont Neuf (1578–1606) which set several trends including wide, raised sidewalks separating pedestrians from the road traffic, plus the first Parisian bridge without houses built on it, and its generous width plus elegant, durable design that immediately became popular for promenading at the beginning of the century that saw Paris take its form renowned to this day. It

1376-568: A variety of vehicles including cars, motorbikes and bicycles. Sidewalk surfing was often used in the early 1960s to describe skateboarding . ) Contemporary sidewalks are most often made of concrete in North America, while tarmac , asphalt , brick , stone , slab and (increasingly) rubber are more common in Europe. Different materials are more or less friendly environmentally: pumice-based trass , for example, when used as an extender

1462-529: Is a common problem with unsalted sidewalks. The ice forms a thin transparent surface film which is almost impossible to see, and so results in many slips by pedestrians . Riding bicycles on sidewalks is discouraged since some research shows it to be more dangerous than riding in the street. Some jurisdictions prohibit sidewalk riding except for children. In addition to the risk of cyclist/pedestrian collisions, cyclists face increase risks from collisions with motor vehicles at street crossings and driveways. Riding in

1548-416: Is less energy-intensive than Portland cement concrete or petroleum-based materials such as asphalt or tar-penetration macadam. Multi-use paths alongside roads are sometimes made of materials that are softer than concrete, such as asphalt. Some sidewalks may be built like a Meandering Sidewalk. The meandering sidewalk is the wavy sidewalk that veers back and forth at the side of the road, no matter how straight

1634-409: Is not represented. Commonwealth citizens are eligible to apply for British emergency passports . Australia issues Documents of Identity in exceptional circumstances to resident Commonwealth citizens who are unable to obtain valid travel documents from their countries of origin and must travel urgently. The close association amongst Commonwealth countries is reflected in the diplomatic protocols of

1720-650: Is required, as in historic town centers. For example, in Melbourne , Australia , bluestone has been used to pave the sidewalks of the CBD since the Gold rush in the 1850s because it proved to be stronger, more plentiful and easier to work than most other available materials. Pre-cast concrete pavers are used for sidewalks, often colored or textured to resemble stone. Sometimes cobblestones are used, though they are generally considered too uneven for comfortable walking. In

Thousands of potential Commonwealth recruits have been turned away due to a lack of eligible vacancies. Gurkha soldiers from Nepal , though it is not a Commonwealth country, have long fought alongside British and Commonwealth troops. They continue to be recruited by

2408-668: The British Commonwealth Occupation Force in post-war Japan. After the Second World War ended, the British Empire was gradually dismantled. Most of its components have become independent countries, whether Commonwealth realms or republics, and members of the Commonwealth. There remain the 14 mainly self-governing British overseas territories which retain some political association with the United Kingdom. In April 1949, following

4472-577: The United Kingdom's cosmopolitan role in world affairs became increasingly limited, especially with the losses of India and Singapore. Whilst British politicians at first hoped that the Commonwealth would preserve and project British influence, they gradually lost their enthusiasm, argues Krishnan Srinivasan . Early enthusiasm waned as British policies came under fire at Commonwealth meetings. Public opinion became troubled as immigration from non-white member states became large-scale (see also: Commonwealth diaspora ). The term New Commonwealth gained usage in

4558-423: The United Kingdom, have preferential citizenship acquisition or residency policies for Commonwealth citizens. Initially, Commonwealth countries were not considered to be "foreign" to each other as their citizens were British subjects . Citizenship laws have evolved independently in each Commonwealth country. For example, in Australia, for the purpose of considering certain constitutional and legal provisions in

4644-660: The United States and Canada, the most common type of sidewalk consists of a poured concrete "ribbon", examples of which from as early as the 1860s can be found in good repair in San Francisco, and stamped with the name of the contractor and date of installation. When Portland cement was first imported to the United States in the 1880s, its principal use was in the construction of sidewalks. Today, most sidewalk ribbons are constructed with cross-lying strain-relief grooves placed or sawn at regular intervals, typically 5 feet (1.5 m) apart. This partitioning, an improvement over

Following the Great Fire of London in 1666, attempts were slowly made to bring some order to the sprawling city. In 1671, "Certain Orders, Rules and Directions Touching the Paving and Cleansing The Streets, Lanes and Common Passages within

4816-473: The beginning of the modern Commonwealth. Following India's precedent, other nations became republics, or constitutional monarchies with their own monarchs. Whilst some countries retained the same monarch as the United Kingdom, their monarchies developed differently and soon became essentially independent of the British monarchy. The monarch is regarded as a separate legal personality in each realm, even though

4902-515: The benefits of greater slip resistance and electrical insulating properties. Manholes are usually outfitted with metal, polypropylene , or fiberglass steps installed in the inner side of the wall to allow easy descent into the utility space. Manholes are usually round, primarily because roundness is the best shape to resist the compression of the earth; covers are round because they are easier to manufacture than square or rectangular shapes, they are easier to move by rolling, and they can't fall into

4988-420: The concrete will shrink while setting. In the United Kingdom , Australia and France suburban sidewalks are most commonly constructed of tarmac . In urban or inner-city areas sidewalks are most commonly constructed of slabs, stone, or brick depending upon the surrounding street architecture and furniture . Commonwealth of Nations The Commonwealth of Nations , often simply referred to as

5074-662: The continuous slab ribbon, was patented in 1924 by Arthur Wesley Hall and William Alexander McVay, who wished to minimize damage to the concrete from the effects of tectonic and temperature fluctuations, both of which can crack longer segments. The technique is not perfect, as freeze-thaw cycles (in cold-winter regions) and tree root growth can eventually result in damage which requires repair. In highly variable climates which undergo multiple freeze-thaw cycles, concrete blocks will be formed with separations, called expansion joints, to allow for thermal expansion without breakage. The use of expansion joints in sidewalks may not be necessary, as

5160-570: The country sought closer ties with the Anglophone world . Under the formula of the London Declaration , Charles III is the Head of the Commonwealth . However, when the monarch dies, the successor to the crown does not automatically become the new head of the Commonwealth. Despite this, at their meeting in April 2018, Commonwealth leaders agreed that Prince Charles should succeed his mother Elizabeth II as head after her death . The position

Prior to Togo's admission at the 2022 Commonwealth Heads of Government Meeting , Togolese Foreign Minister Robert Dussey said that he expected Commonwealth membership to provide opportunities for Togolese citizens to learn English and access new educational and cultural resources. He also remarked that

5332-489: The direction opposite to traffic in the adjacent lane is especially risky. Since residents of neighborhoods with sidewalks are more likely to walk, they tend to have lower rates of cardiovascular disease, obesity, and other health issues related to sedentary lifestyles. Also, children who walk to school have been shown to have better concentration. Some sidewalks may be used as social spaces with sidewalk cafés , markets , or busking musicians, as well as for parking for

5418-585: The end of the Suez Crisis. The first member to be admitted without having any constitutional link to the British Empire was Mozambique in 1995 following its first democratic elections. Mozambique was a former Portuguese colony . Its entry preceded the Edinburgh Declaration and the current membership guidelines. In 2009, Rwanda became the second country to be admitted to the Commonwealth not to have any constitutional links to Britain. It

5504-549: The former rules were consolidated into a single document. These requirements are that members must accept and comply with the Harare principles , be fully sovereign states , recognise King Charles III as head of the Commonwealth, accept the English language as the means of Commonwealth communication, and respect the wishes of the general population with regard to Commonwealth membership. These requirements had undergone review, and

5590-479: The highest qualities of the Spirit of Man: friendship, loyalty, and the desire for freedom and peace". However, the British treasury was so weak that it could not operate independently of the United States. Furthermore, the loss of defence and financial roles undermined Joseph Chamberlain's early 20th-century vision of a world empire that could combine Imperial preference, mutual defence and social growth. In addition,

5676-426: The likelihood of a vehicle/pedestrian crash. Sidewalk presence had a risk ratio of 0.118, which means that the likelihood of a crash on a road with a paved sidewalk was 88.2 percent lower than one without a sidewalk. The authors wrote that "this should not be interpreted to mean that installing sidewalks would necessarily reduce the likelihood of pedestrian/motor vehicle crashes by 88.2 percent in all situations. However,

5762-503: The opening. But in the United Kingdom they are nearly always square, or rectangular, in shape, at least at street level. Manholes can also be found in a triangular shape (e.g. in Cambridge , and surrounding villages). Composite ( fiberglass ) manholes are commonly used in applications where infiltration, exfiltration, or corrosion by hydrogen sulfide (from sewer gas ) are a concern, or where structures need to be factory integrated into

5848-416: The other hand, the implementation of schemes which involve the removal of sidewalks, such as shared space schemes, are reported to deliver a dramatic drop in crashes and congestion too, which indicates that a number of other factors, such as the local speed environment, also play an important role in whether sidewalks are necessarily the best local solution for pedestrian safety. In cold weather, black ice

5934-612: The power to rule on whether members meet the requirements for membership under the Harare Declaration. Also in 1995, an Inter-Governmental Group was created to finalise and codify the full requirements for membership. Upon reporting in 1997, as adopted under the Edinburgh Declaration , the Inter-Governmental Group ruled that any future members would "as a rule" have to have a direct constitutional link with an existing member. In addition to this new rule,

6020-496: The presence of a sidewalk clearly has a strong beneficial effect of reducing the risk of a 'walking along roadway' pedestrian/motor vehicle crash." The study does not count crashes that happen when walking across a roadway. The speed limit risk ratio was 1.116, which means that a 16.1-km/h (10-mi/h) increase in the limit yields a factor of (1.116) or 3. The presence or absence of sidewalks was one of three factors that were found to encourage drivers to choose lower, safer speeds. On

Newfoundland never did as due to economic hardship and the need for financial assistance from London, Newfoundland voluntarily accepted the suspension of self-government in 1934 and governance reverted to direct control from London. Newfoundland later joined Canada as its tenth province in 1949. Australia and New Zealand ratified

In 2022, the former French territories of Togo and Gabon joined the Commonwealth. The Commonwealth comprises 56 countries, across all inhabited continents. 33 members are small states, including 25 small island developing states. In 2023,

6278-433: The road, with the center section of the road for motorized vehicles. Crosswalks provide pedestrians a space to cross between the two sides of the street at predictable locations. On rural roads, sidewalks may not be present as the amount of traffic (pedestrian or motorized) may not be enough to justify separating the two. In suburban and urban areas, sidewalks are more common. In town and city centers (known as downtown in

6364-526: The same person is monarch of each realm. At a time when Germany and France, together with Belgium, Italy, Luxembourg, and the Netherlands, were planning what later became the European Union , and newly independent African countries were joining the Commonwealth, new ideas were floated to prevent the United Kingdom from becoming isolated in economic affairs. British trade with the Commonwealth

6450-539: The same section of path as pedestrians. Sidewalks have operated for at least 4,000 years. The Greek city of Corinth had sidewalks by the 4th-century BC, and the Romans built sidewalks – they called them sēmitae . However, by the Middle Ages , narrow roads had reverted to being simultaneously used by pedestrians and wagons without any formal separation between the two categories. Early attempts at ensuring
