Circular pipe culvert consists of two parts: the hole body and the mouth of the cave. The tunnel body is the main body of the water passage, which is mainly composed of pipe body, foundation and joint. The entrance of the cave is the connection part of the tunnel body, subgrade and water flow, which mainly has two forms: splayed wall and straight wall.
Assembled pipe culvert is divided into cement pipe culvert and steel galvanized corrugated pipe culvert. Steel corrugated pipe culvert, also known as corrugated pipe culvert, refers to the threaded corrugated pipe for culverts buried under highways and railways. It is a circular steel pipe made of corrugated steel plates or assembled by corrugated steel plates. The corrugated structure of metal corrugated pipe culvert can make the culvert pavement stress reasonable, the load distribution is uniform, and it has certain anti-deformation ability, which can solve the damage problem of concrete structures of bridges and pipe culverts in northern cold areas (frost). There is no expansion joint on the pavement to improve driving comfort; It is beneficial to improve the "staggered platform" phenomenon at the junction of soft soil foundation structure and embankment, and improve the driving safety. The post-construction operation and maintenance cost of corrugated pipe culvert is low, and the actual project cost is also lower than that of the same span bridge and culvert.
