It is only the same weight as a reinforced concrete culvert with the same inner diameter, which brings great convenience to construction. It can be installed with a small lifting machine. At the same time, the transportation and loading and unloading costs are also greatly reduced. .
Good durability
Existing structural examples show that the service life of galvanized corrugated pipes can reach more than 10 years. For ordinary projects, this service life can fully meet the requirements.
Adopting factory production
Metal corrugated culverts are produced in a centralized manner in factories, which greatly reduces product costs and ensures stable and reliable quality.
Convenient construction and installation
Since the installation process of metal bellows is a simple bolting and seating process, and can be assembled on site, the installation process is very convenient.
Improve driving comfort and safety
The structural stress situation is reasonable, the load is distributed uniformly, and it has a certain resistance to deformation, which is conducive to improving the soft soil foundation structure, the staggered position at the junction of the structure and the embankment phenomenon, improving driving comfort and safety.
Short production cycle
Using standardized design and production, the design is simple and the production cycle is short.
It solves the problem of frost damage to concrete bridges and pipe culvert structures in cold areas.
