Design Points And Application Advantages Of Metal Corrugated Culverts

Corrugated culvert pipe suppliers introduce you: The theoretical basis of metal corrugated culvert design is plate and shell theory, material mechanics, computational mathematics, etc. There are many parameters in the design of metal corrugated culverts. Due to the different uses of metal corrugated culverts in the system, the focus of their design calculations is different. For example, metal corrugated culverts are used for force-balancing components, which require the effective area of the corrugated tube to be constant or change little in the working range. For measuring components, the elastic characteristics of metal corrugated culverts are linear. Vacuum seals require the vacuum tightness, axial displacement and fatigue life of the bellows. For valves used as seals, the bellows should have certain pressure resistance, corrosion resistance, temperature resistance, working displacement and fatigue life.

Corrugated Culvert Pipe

According to the structural characteristics of corrugated culvert pipe china, the bellows can be made up of toroidal shells, flat cone shells or toroidal plates. The design and calculation of the bellows is the design and calculation of a circular shell, a flat cone shell or a ring plate.

The design and calculation parameters of metal corrugated culvert are stiffness, stress, effective area, instability, allowable displacement, pressure resistance and service life.

Calculation of the stiffness of metal corrugated culverts. The stiffness of corrugated tubes is divided into axial rigidity, bending rigidity, torsional rigidity, etc. according to different load and displacement properties. At present, in the application of bellows, most of the stresses are axial loads, and the displacement mode is linear displacement.

Corrugated culvert pipe is made by corrugating a thin metal plate and rolling it into a pipe section, which can increase the stiffness of the pipe section and the resistance to the pressure of the pipe shaft. Asphalt is sprayed on the construction site, and the double-layer anticorrosive treatment guarantees the service life; the culverts built with this type of pipe joint are called corrugated metal pipe culverts. Practice has proved that the use of metal corrugated culverts instead of metal reinforced concrete for culvert construction has unparalleled advantages in terms of construction cycle, construction cost, environmental protection, etc., and the use of metal corrugated culverts for culvert construction can greatly improve road traffic The comfort and safety of the vehicle can avoid the appearance of the “staggered vehicle jumping” of the culvert in the road, which is conducive to solving the problem of the damage of the concrete culvert structure by the cold and frost in the northwest region.

Culverts for highway engineering are generally made of metal reinforced concrete. The use of metal corrugated culverts instead of metal reinforced concrete for culvert construction is a new technology in China. Metal corrugated culverts have quickly replaced metal reinforced concrete construction in highway construction due to its stable performance, convenient installation, environmental protection and low cost. Culverts have broad prospects for development. In highway construction, the use of metal corrugated culverts instead of metal reinforced concrete for culvert construction has a history of more than 100 years. In 1896, the United States took the lead in conducting feasibility studies of corrugated pipe culverts and culverts. Later, in highway construction in the United States, Canada, Australia and other countries, metal corrugated culverts were used for culvert construction. In 1990, Japan's highway design and specifications formulated the technical specifications for the design of corrugated pipes and culverts.

With the installation and use of corrugated pipe culverts around the world, the versatility of this structure in various use cases has been proven. After China's reform and opening up, Shenzhen and Datong coal mines began to import finished corrugated pipe culverts from abroad for culvert construction. After that, Shanghai Highway Management Office, Shanghai Municipal Engineering Design and Research Institute, and Shanghai Tongji University carried out dynamic and static load tests on metal corrugated culverts. The results showed that they can meet the design requirements, fill the gaps in China, and quickly be promoted and applied. The curtain wall has always been used in the construction of highway facilities throughout China. Metal corrugated culverts have been put into the construction of Qinghai Highway. Three years of practice have proved that metal corrugated culverts fully meet the requirements of culvert construction in highway construction in cold northern regions. Practice has proved that the use of metal corrugated culverts instead of metal reinforced concrete for culvert construction has unparalleled advantages in terms of construction cycle, construction cost, environmental protection, etc., and the use of metal corrugated culverts for culvert construction can greatly improve road traffic The comfort and safety of the vehicle can avoid the appearance of the “staggered vehicle jumping” of the culvert in the road, which is conducive to solving the problem of the damage of the concrete culvert structure by the cold and frost in the northwest region.
