The detailed process of bridge guardrail works
Bridge engineering refers to the work of bridge surveying, design, construction, maintenance and verification, as well as the scientific and engineering techniques of this process, which is a branch of civil engineering. The development of bridge engineering depends mainly on the need for transportation. Ancient bridge to pedestrians, livestock-based, little load, bridge slope can be steep, and even can lay the steps. Since the railway has been carried out after the bridge, the load on the bridge is increasing, the slope and curve of the line requirements are high, and the need to build a railway network to increase economic efficiency, therefore, in order to cross the rivers and canyons, Bridge to large span development. Stone, wood, cast iron, wrought iron and other bridge materials, obviously substandard requirements, and the mass production of steel just to meet this requirement.
