Introduction:

Steel corrugated culvert is also called the corrugated pipe culvert, it is to point to lay buried culvert under the condition of road and railway use thread bellows. It is made of corrugated sheet metal rolls made of corrugated iron or with makings to circular corrugated pipe, widely used in highway, railway culvert, tong road, bridge, tunnel, temporary retaining wall of roadway supporting service road, drainage pipe and all kinds of mine and other projects. Productions are fabricated according to customer s request or the drawings requirement. These pipes are very adaptable to various environment.

Producing process of corrugated culvert pipes

raw material → cutting → welding → wave rolling → assembling → drilling → galvanizing → storage

(PS: Corrugated structural plates are hot-dip-galvanized with 3-ounce zinc coating, which gives the plate a 40% longer life span than regular corrugated steel pipe.)

The diagram of construction process

1. Wedge backfill
2. The distance is not less than m from material to two sides of corrugated culvert pipe.
3. Paving material on both sides symmetrically at same time.
4. Vertical construction process that can from the center to both sides of the culvert, but also from both sides to the center of the culvert.
5. Unsymmetrical backfill would cause the pipe body irregular distortion, easy to cause an accident and collapse.
6. The pipe body would present regular deformation when layered symmetric backfill. After the termination of filling soil, the pipe body would repristinate original state.

Advantage:

1. Our products has both rigid and flexible, load distribution, certain resistance to deformation
2. The use of standardized designs, factory-scale production, short production cycle, high efficiency, reduce costs and improve quality
3. On-site installation of speed, short construction period, social economic benefit
4. Year-round construction, construction does not subject to seasonal effects, without environmental impacts
5. Effectively solve the freezing cold north area of concrete bridges and culverts due to repeated failure problems
6. Especially for loading soil, expansive soil, loess and other special areas, to avoid distortion caused by uneven ground settlement of the culvert damage
7. Reduction of cement, sand, gravel and other conventional building materials used, environmentally significant
8. Compared with concrete bridges and culverts, the same span of the corrugated steel bridge and lower total cost

PRODUCT CHARACTERISTICS

1. Ability to adjust the foundation deformation, low request of foundation capability and flatness. The cost of engineering practice is equal or less than other culverts.

2. The most obvious advantage is short construction time, building project and socket installation can be carried out separately, then conduct the whole assembly.

3. Centralized manufacturing, productive process is not affected by the environment. Avail to lowering cost, controlling quality.

4. Easy installation, does not need large equipment.

5. Solution to culvert damage from frost.

6. Reduce or abandon normal construction materials, like concrete, yellow sand, cobblestone, and woods, which means a lot to environment.

7. Rational load to the structure, load force distribution, anti deformation.

8. Standardized design, simple design and manufacture, short production period.

9. Improve the structure of the soft soil foundation and the interlocking of the junction of the embankment, which improves the safeness of the car on the bridge. The maintenance cost of corrugated metal pipes is very low, and the cost of engineering practice is also lower than other bridge culverts.

10. Excellent pavement performance, foundation requirement is low, easy construction, fast installation, shorten project period, beyond comparison. Play a positive role in new highway construction and foundation maintenance project.

 LN large diameter assembled corrugated culvert, galvanized metal corrugated culvert, high quality products

 Characteristics of metal bellows
1 High strength, due to its unique corrugated structure, it is 15 times more compressive than cement pipes of the same diameter.
2 Convenient transportation, the weight of bellows culvert is only 1/10 to 1/5 of the same diameter cement pipe, even if there is no transportation equipment in a narrow place, it can be transported by hand.
3 long service life, steel corrugated pipe culvert is hot-dip galvanized steel pipe, so the service life is long, the life is 80-100 years, when used in a particularly corrosive environment, the steel with inner and outer surface bitumen is used. The bellows can be improved for more than20 years based on the original service life.
4 Convenient construction: Corrugated pipe culverts are connected by sleeve or flange, and can be customized according to the needs. Even unskilled workers can operate. The construction can be completed in a short time with a small amount of manual operation, which is quick and convenient. .
5 Excellent economy:
The connection method is simple and can shorten the construction period.
