Sheet Pile Wall Thickness

Grades of sheet piling steel.

Sheet pile wall thickness.

A sheet pile wall is required to support a 12 excavation. Please note this value is applied only for passive pressure. Shoreline steel offers these lightweight steel materials available in astm a 857 gr 33 36 bare or galvanized finish. To take into account the friction between the wall and the soil we use friction angle δ φ 2.

The lightweight sheet piling can be used to prevent erosion to protect. Measures to prevent retained soil form being washed out through the small holes are easy to implement. The planks are nailed together with the middle plank offset forming a tongue on one edge and a groove on the other. 1 of total mass of the complete order.

Note that generally speaking pitting corrosion does not affect the overall stability of the retaining wall. This type of pile is made with three planks 5 cm 8 cm or 10 cm in thickness.

The basic specification for steel sheet piling in the united states has been astm a 328 published by the american society of testing materials. The us army corps of engineers design of sheet pile walls engineer manual from 1994 recommends accounting for a safety factor for the allowable bending stress of 50 50. Width thickness of pan weight length squareness straightness single pile interlocked piles e 8mm 8 e 12 12 e 18 e 18mm 1 of ends 2 3 2 3 0 5mm 0 6mm 0 8mm 1 2mm 4 200mm 10mm 0 2 notes. Hence f a 50 x ksi of the given steel grade therefore.

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. Sheet pile walls are constructed by driving sheet pile sections into the ground. The planks are connected by using a pair of staggered bolts at 80 cm center to center at intermediate points. In most cases the design with a sacrificial thickness of steel is the most cost effective.

The soil is uniform as shown in the figure. All the lightweight sheet piling can be cut to the length you need it. Use factor of safety 1 5 for. Sheet pile design has to consider moments and design life.
