Product Description:
Corrugated pipe culvert is also called metal corrugated pipe culvert or steel corrugated culvert.
refers to lay buried in the highway, railway culvert under the screw corrugated pipe, it is made of corrugated metal plate roll or semicircle corrugated steel plate made of makings of circular corrugated pipe.
widely used in highway, railway, bridge, tunnel, retaining wall and all kinds of mines, the retaining wall of roadway supporting engineering of culvert.
Specification:
Helical Corrugated Metal Pipes Culverts is available in diameters ranging from 8 inches to 36 inches.The length is available in diameters of 10 feet to 20 feet,or custom made.
Fitting can be fabricated into any type of structure including tees, elbows and reducers. Pre-fabricated fittings are more economical and have superior hydraulic characteristics when compared to concrete structures.
Helical Corrugated Metal Pipes Culverts is available in long lengths, and its light weight,allows it to be unloaded and handled with small equipment.
precautions
1. If the buoyancy is affected by the rise of water level, causing the pipe to float up, anchoring facilities should be taken to prevent the pipe from floating up during backfilling.
2. If the construction environment corrodes the steel corrugated pipe culvert, measures such as increasing the thickness of the pipe wall or applying protective film should be taken.
3. For steel corrugated pipes with a diameter greater than 3 meters, if the openings at both ends of the pipe are in the form of a straight wall, the openings should be reinforced with reinforced concrete.
4. If the longitudinal slope of the bottom of the corrugated pipe culvert is greater than 5%, necessary anti slip measures should be taken.
5. When the foundation is soft, special treatment must be carried out to set a relatively large pre camber as much as possible.
6. In areas with abundant rainfall, the backfill material for culvert pipes must use graded sand and gravel or graded crushed stone with good permeability.
