Cheung Tsing Tunnel
Cheung Tsing Tunnel, also spelled Cheung Ching Tunnel, is a dual tube 3-lane tunnel on Tsing Yi Island, Hong Kong. It is part of Route 3. Its east end connects to Cheung Tsing Bridge and west Cheung Tsing Highway. The tunnel was opened on 22 May 1997 and is the second toll-free tunnel in Hong Kong. Its length is about 1.6 kilometres. Construction The tunnel was given the name "Cheung Ching" (長青) because it is beneath Cheung Ching Estate, the first public housing estate on the island. Construction through the granite of Tsing Yi Peak required explosives to get through the hardness of the hill. To prevent dislodging of rocks and buildings on the surface slopes the rocks were reinforced by concrete and steel. Although the tunnel used explosives in its construction, boring was more used as the primary digging procedure. Construction commenced in May 1993 and was completed in January 1997. Management The tunnel was managed by Tsing Ma Management Limited under Tsing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Route 3 (Hong Kong)
Route 3 () is a series of expressways in Hong Kong that runs from Sai Ying Pun on Hong Kong Island to Yuen Long in the New Territories, linking West Kowloon, Kwai Chung and Tsing Yi.

Explosives
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Tunnels In Hong Kong
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", w ...

Tsing Kwai Highway
Tsing Kwai Highway () is a section of Route 3 in Hong Kong, previously known as Route 3 - Kwai Chung Section. From its junction with West Kowloon Highway at Mei Foo Roundabout, the expressway runs in the form of a three-kilometre dual-four-lane viaduct atop Kwai Chung Road and Kwai Tai Road, circumscribing the container terminals to reach the Rambler Channel. Then, the highway crosses the channel along a 500-m bridge known as Cheung Tsing Bridge (or Rambler Channel Bridge), and ends at its junction with the Cheung Tsing Tunnel. Tsing Kwai Highway was opened on 19 February 1997.

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.
