Steel Sheet Pile Bulkhead

The vertical load capacity of a sheet pile would be similar to that of an h pile or pipe.

Steel sheet pile bulkhead.

We operate four mini mill roll forming operations that produce 30 different piling sections in six different configurations. 4 3 4 high strength sheet piling. There is no difference in the stress calculation. It can be driven into hard dense soils and even soft rock.

Steel sheet piling with yield strengths of 50 000 psi 14 66 x 107kg mm2 or greater are commercially available. This grade has been satisfactory for most applications in that it provided a relatively high yield point for design and a high ultimate strength for drivability. Its also stability depends upon the formation of enough lateral resistance of soil adjacent to the embedded length of the bulkhead and upon the anchor rods. For example say in a section of plans which has 500 feet 152 m of wall length and a sheet piling length of 48 feet 14 6 m you require a minimum design moment of 75 8 k in ft 28 kn m m.

Then any hot rolled steel piling section meeting the required 75 8 k in ft. Shoreline steel began manufacturing steel piling in 1983 and has established a worldwide reputation as a provider of quality american made steel sheet piling. The pile transfers pressure from the high side of the wall to the soil in front of the wall. When a flexible bulkhead usually made of steel piles deflects and bends under the effect of a lateral force.

The most common materials for seawalls and bulkheads are steel concrete and timber. Shunli steel group the chairman company of specialized committee china cold formed sheet piles is also known as the first level cold formed sheet pile manufacturer vice chairman company of chinese confederation of roll forming industry national high technology enterprise jiangsu famous trademark and excellent enterprise in cold formed steel industry. Design moment would be considered equivalent. According to the sheet pile material a bulkhead may be classified as flexible or rigid.

In piling hot rolled steel sheet pile and cold formed steel sheet pile are two primary methods of manufacturing sheet pile. The basic specification for steel sheet piling in the united states has been astm a 328 published by the american society of testing materials. In temporary cofferdams the sheet piles can be braced. Steel piles can be driven into the foundation without extensive excavation.

Properly designed and protected steel sheet piles can meet design lives of 75 or 100 years. A continuous anchor wall used to restrain the top of a steel sheet pile bulkhead is to resist a force of 85 kn m spaced at 1 3 m. Grades of sheet piling steel. The top of the wall is 1 m below the ground surface.

Factors of safety of 2 for tie force and 1 5 for net passive force are considered.
