Strictly speaking some tests measure the accessible void the total amount of void space accessible from the surface cf. Mechanical and hydraulic characterization of plastic concrete for seepage cut off walls.

And then yu et al. Furthermore hydraulic conductivities were assigned to each steel pipe and joint section in the sp js model such that the entire hydraulic conductivity of the spsp cutoff wall equals the equivalent hydraulic conductivity assigned in the ul model that is hydraulic conductivities of 2 5 10 6 1 3 10 6 1 3 10 7 and 1 3 10 8 cm s were. Empty spaces in a material and is a fraction of the volume of voids over the total volume between 0 and 1 or as a percentage between 0 and 100. They are used water front structures and cofferdams temporary structure made of interlocking sheet piles making up an impermeable wall surrounding an area often for construction works as in fig.

Wooden piles are made from the trunks of tall trees. Prefabricated piles are driven into the ground using a pile driver driven piles are constructed of wood reinforced concrete or steel. Permeability and watertightness ge n e ra l l y the same pro p e rt i e s. Concrete low water cement ratio and 7 day moist cure make concrete more impermeable hydraulic permeability test apparatus can apply 3000 psi water pressure for measuring concrete permeability.

Porosity or void fraction is a measure of the void i e. Concrete piles are available in square octagonal and round cross sections like franki piles they are reinforced with rebar and are often prestressed steel piles are either pipe piles or some sort of beam. There are many ways to test porosity in a. Figure 7 1 seepage beneath a a concrete dam b a sheet pile sheet piles are interlocking walls made of steel timber or concrete segments.

Standard sheet pile walls usually do not have hydraulic conductivity values greater than 10 7 cm s cost as presented by pearlman 1999 the cost of a sheet pile barrier ranges from 15 40 ft 2 depending on the depth equipment used type of joint and type of sealant.
