Concrete Bridge Project

Until now, there were not many pedestrians running along the street, as the population was small. However, the population increased in the 1960s and 1970s. Since the pedestrian traffic such as a pedestrian bridge is very important, the government thinks that it is necessary to increase the total pedestrian traffic such as a pedestrian bridge. Along with the changing times, the safety and technical nature of the bridge structure also changed and improved. Currently, almost all pedestrian bridges in Hong Kong, including the prestressed concrete bridge, are made of concrete.

The bridge is a post-tension concrete structure. Concrete structures are usually 10 times heavier than equivalent steel designs. The bridge is not made of standard concrete recipe, but it is made of a new concrete recipe designed to keep it clean. In the main span bridge, the concrete floor deck, the roof, and the diagonal strut each have a rear tension cable that compresses the concrete after the concrete solidifies. It is expected to adjust each time the strut moves to a different base with different fulcrums

The style of the full bridge project brings a dramatic effect, like a diagonal bridge, a tower tower, a high cable. However, in terms of function and structure, it is actually a truss bridge and the span is completely self-sustaining. The span of the bridge adopts a new concrete truss design devised for the project, that is, "concept of I-shaped beam that was reinvented". Concrete truss bridges are rarely constructed and rarely exist. The vertical web of beams is a series of triangular concrete diagonal struts along the centerline and the diagonal of the bridge changes across the bridge so they align with the pipes of the central tower and eventually a fake Form the stay cable appearance.

The old beam bridge is made of wood or stone, and now it is made of concrete. The actual name of the concrete used for the girder bridge is called prestressed concrete, the most commonly used material of the girder bridge, this concrete can withstand the compression of the girder bridge, the reinforcement of the concrete is It helps to withstand the tension bridge. Prestressed concrete is one of the cheapest structural materials of Liang Bridge. It is only 250 feet long. Beam bridges can still cover very long distances, but they must be linked to the tower known as the "daisy chain" in the bridge world. When using a daisy chain, the bridge becomes "continuous span". One of the longest or longest bridges is called "Ponchart Rain Causeway of the Lake"
