Sheet Pile Wall

Sheet piles that are connected in the locks form a continuous wall. The most common use of this structure is to realize cofferdams or to temporarily secure foundation pits. Sheet piles are usually rammed or vibrated. Permanent sheet pile walls are also built as a part of flood protection, embankment walls and it is also possible to use them in the process of remediation of contaminated soils.

The GEO5 Sheeting Check program is used to make advanced designs of anchored or strutted sheet pile retaining walls (also Diaphragm, Pile or Soldier pile walls are supported). It allows the user to model the real structure behavior using stages of construction, to calculate the deformation and pressures acting upon the structure,

to verify the internal anchor stability or to verify steel, RC or timber cross-sections and the bearing capacity of the anchors.

The GEO5 Sheeting Design program is used to perform a quick design of cantilevered sheet pile walls or a basic design of anchored sheet pile walls (tieback). The program calculates the required length of the structure in soil,

the internal forces on the structure and verifies cross-sections (RC, steel, timber).

VINYL SHEET PILING

Vinyl sheet piling is a relatively new type of sheeting which can be applied in a wide variety of ways for seawalls and other applications of sheet piling. It is generally manufactured by continuous extrusion. The raw material, plastic resin compound, is melted and pushed through a die. This die shapes the plastic into the computer aided design cross section. The sheet is then cooled and cut to length. The sheets can be extruded to the length required for different retaining wall applications.

Vinyl sheeting comes in a number of configurations. The most common configuration is a Z-sheet type of configuration similar to those shown in Figure 4. Others are similar to aluminium sheeting shown in Figure 7. The individual sheets have interlocking male and female edges. The interlocking edges are extruded as part of the sheet to insure consistent strength throughout the retaining wall. As is the case with other sheeting, vinyl sheeting requires transition pieces such as corners and intersections. These are designed to interface properly with the other sheeting the manufacturer makes.

Vinyl sheeting is made of a modified polyvinyl chloride (PVC), which makes it suitable for most marine environments and not subject to leaching, corrosion or similar deterioration mechanisms. The technology that has brought us vinyl siding for homes, plastic automotive parts such as bumpers and dashboards, and durable home appliances, is now being utilized to produce a sheet piling for marine retaining walls, sea walls or bulkheads. The vinyl also includes a UV stabilizer to reduce deterioration due to sunlight.

Because vinyl sheet piling generally has a low modulus of elasticity and strength relative to metal sheet piling, deflection frequently becomes the governing factor in the design of the wall, and should be determined in the design process.

Wooden sheet piles

Wooden sheet piles are made in various sizes and forms. The nature of site conditions determine, the choice of a particular type, In places where excavation is small and the ground water problem is not serious, 5 cm x 30 cm to 10 cm x 30 cm wooden planks arranged in a simple row will serve the purpose. If the water-tightness is required to a great extent, lapped sheet piling is used. In this case, each pile is made up of two planks, either spiked or bolted to one another. Thus if only earthen banks of small height are to be supported, a single or double row of  planks properly erected will perform the function of sheet piling. If complete water tightness is desired or pressure of the retained material wakefield or tongue and grooved sheeting is generally used. To facilitate the driving of the piles, they are usually bevelled at foot. This not only assists in driving but also prevents bruising, if the piles encounter hard stratum.
