Scope of application of welded vacuum bellows, metal bellows culvert
1. Metal bellows culvert is a flexible structure, and the bellows has excellent characteristics of lateral displacement compensation in structure, which can give full play to the characteristics of strong tensile performance and superior deformation performance of steel. It has greater resistance to deformation and settlement, and is especially suitable for areas with low foundation bearing capacity such as soft soil, expansive soil, and collapsible loess, and areas prone to earthquakes.
2. Since the construction of metal bellows culvert is simple and the construction period is short (generally, the construction time of a culvert is within one working day), which reduces the exposure time of permafrost and the amount of freezing and thawing is small, so it is especially suitable for permafrost areas. . The metal corrugated pipe culvert has little damage to the environment during construction, and is suitable for areas with fragile ecological environment.
3. The construction of metal corrugated pipe culvert only needs to deal with the foundation and import and export, and the amount of sand and stone materials is small, so it is suitable for areas lacking sand and stone.
4. The construction of metal corrugated pipe culvert requires very little labor, so it is suitable for labor shortage areas.
5. Metal bellows instead of reinforced concrete for culvert construction is beneficial to solve the problem of damage to the concrete structure of pipe culverts in winter in cold northern regions, and is suitable for plateau areas.
6. Due to the use of standardized design and production, the design is simple, the production is not affected by the environment, and the centralized factory production is carried out. The production cycle is short, so it is suitable for projects with high quality requirements and tight schedules.
