Helical corrugated steel pipe (CSP) is a type of corrugated steel pipe that is shaped like a spiral or helix and is commonly used for culverts, storm sewers, and other types of drainage systems. Similar to other corrugated metal pipes, helical corrugated metal pipe has also the corrugation shape. It is made of corrugated steel sheets that are rolled and welded together to form a spiral or helical shape.
The corrugations in the steel sheets provide strength and stiffness to the pipe, while also allowing it to be flexible enough to bend and conform to the shape of the surrounding terrain. More over, helical corrugated metal pipe has the special corrugation - annular pattern corrugations, which not only make the culverts more strong and stiff, but also reduce the roughness of flow through the pipe.
Helical CSP is typically used in transportation and infrastructure projects because of its high strength-to-weight ratio, corrosion resistance, and ability to withstand large loads and high levels of stress. It is also often used in agricultural and residential applications to drain excess water from low-lying areas.
The minimum allowable depth of cover is the largest of:
For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6（m）
For railways H=B/4 and not less than 0.6(m)
There is a possibility to reduce depth of cover provided that suitable checking calculations will be made.
|Flexible structure||Plate thickness||Kinds of standard corrosion protection||Required average min value(um）|
|plates||≧6mm||Hot zinc galvanizing||85|
|≧3mm do < 6mm||Hot zinc galvanizing||70|
|≧1.5mm do < 3mm||Hot zinc galvanizing||55|
|Bolts and nuts||-||Hot zinc galvanizing||45|
