What is a tubular bridge?

Bridge pipes is a specially designed bridge that allows the pipeline to run across rivers, highway overpasses, deep ravines, or geologically or environmentally unstable or vulnerable. Pipes passing through these bridges can be a city supply from a river or reservoir or a irrigation station on large agricultural plantations. In addition, the pipes can transmit waste water from mining operations to loading areas for transport or rail transport. Sometimes they transmit liquefied natural gas from the plant processing area to railway lines or ports for loading tankers. In addition to pipe bridges, there are sometimes pedestrians or maintenance.

The pipe bridge design must take into account the weight of the pipeline at full load and the effects of weather conditions on the pipes themselves and the bridges that hold them. Engineers perform materials testing materials used in pipe construction and structural dynamic stress testing of completed designs for patternCE climate and weather expected in the region where the bridge is to be built. Some designs create bridges that protect the weighted natural resources and leave as few traces in the wilderness areas. Whenever possible, the hung bridges are designed to carry pipes above the ecosystems below; This often includes designs that are both practical and visually attractive.

Many hanging bridges above the rivers or ravages are designed on site and carefully built to withstand extreme weather and wind conditions. Bridges, which are designed from steel and prestressed concrete, are often built near segments and then connect over the abutments and peeled supports. One such bridge in South Africa was connected just outside the place. Then the whole bridge weighing 156.5 short tons (142 metric tons) was lowered to the site using a heavy loading crane. After the completed bridge has been fully applied to its support systemém, more than 441 short tons (400 metric tons) were added to the concrete track and pedestrian railing.

Bridges that carry water pipes in northern countries must also consider winter effects. Therefore, these bridges can be built, which clad iron pipes in the so -called cross pipe bridge crossings. These mechanical transitions include aluminum cladding around iron pipes, with a heated source inside that keeps water at a constant temperature, regardless of how cold weather. These isolated pipe designs help ensure that urban water supplies are not endangered by freezing pipes.
