1. because of the metal corrugated pipe culvert construction is simple and the construction period short ( ordinary culvert construction time within an office day within the office days ), the reduction of the years of the permafrost exposure time, the amount of freeze-thaw is small, so particularly suitable for use in the permafrost regions. The damage to background of metal corrugated pipe construction is small, suitable for areas with weak living habits.
2. metal corrugated pipe is a kind of flexible structure, the corrugated pipe has the good special property of lateral repaying displacement, and can fully display the special place with strong tensile property and excellent performance, and has great anti - deformation and anti - settlement experience, especially suitable for soft soil, expansive soil and collapsible loess foundation bearing capacity
3. the construction of metal bellows replacement steel cement for culvert construction is helpful to solve the damage problem of pipe cement structure in cold winter in the cold region of the north, and is suitable for the plateau area.
4. the construction of metal corrugated pipe culverts needs only a small number of people, so they are suitable for use in the kui areas.
5. the construction of metal bellows culvert only needs to be disposed about the foundation and the import, and the amount of sand and stone materials is small, so it is suitable for the areas with shortage of sand and stone.
6. because of the suitability and use of standardized preset, production, simple, production is not affected by the background, centralized production of production, production cycle is short, so suitable for use of high-quality, tight construction projects.
Steel corrugated culvert pipe is the replacement of pipe culvert, slab, and small bridges the quality highway building materials. The product has short construction period, light weight, easy installation, good durability, low cost, strong resistance to deformation and reduction
The advantages of the Queen maintenance cost, which is suitable for the cold frozen soil area, soft soil subgrade zone and deep fill zone, can save a lot of funds, and has obvious economic benefits.
Advantages of the bellows:
( 1 ) culvert pipe, bellows culvert, steel corrugated pipe culvert and metal ripple culvert pipe shall be adaptable to the foundation deformation, and have lower requirements for bearing capacity and smoothness of foundation, and the actual cost of the project is greater than those of the same span
Close or lower.
( 2 ) the short construction period is the most obvious advantage, and the civil engineering and pipe installation can be implemented separately.
( 3 ) factory centralized production, production is not affected by the environment, and it is favorable to reduce cost and control quality.
( 4 ) the culvert pipe, corrugated pipe culvert, steel corrugated pipe culvert and metal corrugated pipe culvert are easy to be installed on the site without the use of large equipment.
( 5 ) to solve the problem of the damage of the north cold area ( frost ) to the bridge and the concrete structure of pipe culvert.
( 6 ) reduce or abandon general building materials, such as cement, sand, stone, wood, environmental protection is of profound significance.
