Sheet pile consists of the FSP-VL or FSP VL of material to the grades and dimensions provided on the plans. Steel sheet piling is quite flexible causing earth pressures to redistribute or differ from the classical hydrostatic distribution. Temperatures - Driving temperatures will not damage the function of the A-30. Excavation is generally required when capping or trenching JFE sheet pile and for placement of tie rods or anchors. A dewatering system consisting of sumps and pumps or wells may be required depending on NS-SP subsurface conditions. An excavation and This is due to SKSP the interdependence between the type of deflection or yield of the buried portion of the VL sheet piling and the corresponding distribution of passive earth pressure. However, in some rare instances it can be physically damaged if the driving temperatures cause the material to burn. Voids due to driving.

During pile driving operations, voids may form adjacent to the webs and flanges of the JFESP sheet piling due to soil drawdown. Typically, these voids are first pumped free of any water present, either due to seepage or rain, and then backfilled with a cement-bentonite-sand slurry. With increasing SP VL flexibility, the yield of the TSP buried part assumes the character of a rotation about the lower edge of the bulkhead causing the center of the passive pressure to move closer to the dredge line.

Sheet piles have excellent resistance to type 5 or VL or SP-VL. It is recommended that clean sands and gravels be used as backfill for retaining walls whenever possible. As a consequence, if a reduction in the maximum NKSP bending moment calculated by the free earth support method is neglected, an uneconomical and wasteful design will result. Very low levels of contaminants such as oils, fuels, gasolines, coal tars, creosote and others may be present without deteriorating A-30. Check with your local representative before using in the presence of any contaminants. However, if the KSP moment reduction is considered, a lower section modulus will be required introducing the possibility of using a lighter VL piling section.

A pH level between 4 and 9 is generally safe*. We request information about any projects where A-30 may be in contact with chemical KSP contaminants. The slurry should be fluid enough to fill the voids and strong enough to approximate the SP-VL strength of the insitu material. We will advise and make recommendations based on each individual case and contaminant level. In particular it has been observed that the bending moment in sheet piling generally decreases with increasing flexibility of the FSP VL piling. This in turn decreases the maximum bending moment. dewatering plan should be submitted by the contractor for review prior to commencement of work. Material placed behind the wall should be compacted to prevent settlement. Rowe 24, 25, 26 , 27 has established a NKSP definite relationship between the degree of flexibility of an anchored bulkhead, expressed as a coefficient and the reduction of the actual bending moment, M, as compared to the free earth support value, max.We recommend driving the pile with the male interlock, ball, or thumb etc.leading to prevent the interlock from accumulating soil or debris.

NS-SP and SKSP and TSP and KSP show the relationship between the ratio M/M max and p for both medium dense and very dense granular soils The amount of compaction required depends on the material used. Over compaction could induce additional type 5 lateral pressures that may not have been accounted for in the TSP design.. For a given wall of height, H, analyzed by the free earth support method, the designer can develop “structural curves” for various piling sections and each grade of steel. If the FSP-VL pile is driven with the female side leading, we recommend inserting a bolt or other object at the bottom of the pile to keep the interlock free from soil or other debris. Any section SKSP falling below the moment reduction curve for the appropriate relative soil density would be inadequate. A design example is given at the end of Problem No. 1 illustrating the use of Rowe’ s Moment Reduction Theory Typically, granular fill is placed in thin lifts, with each lift compacted before the next is placed. Piles should be driven to their final depth at the initial driving time.

If NKSP or JFE or JFESP is to be placed on both sides of a wall, placement should be in simultaneous equal lifts on each side. Sheet piles come in a variety of configurations and sizes. The piles are a Frodingham 2N by British Steel. There are some situations in which the use of clay backfill is unavoidable, as in backfill for walls in levees. Note the tight interlock. The amount of A-30 is more critical in the tight hot rolled piles. This particular pile requires a depth of about 2 ~ 3 mm of A-30.

Under these circumstances NS-SP very strict controls on compaction are JFESP required. Curves for three wall flexibility numbers are given. The FSP-VL designer, knowing the stability number, S, and the depth to height ratio, can determine the moment reduction and, therefore, size the piling for a particular flexibility p. Values of p between those given can be interpolated. This expedites the process. After the center interlock is type 5 filled, they lowered the pile and leveled it before applying the A-30 to the outer interlock. Use a brush to help level the A-30 and to coat the inner side of the JFE interlock. The stability number concept will be expanded in a later section. Fixed Earth Support Method (Equivalent Beam Method) -- Call your local representative or (800) 999-3959 if you have any questions concerning Adeka Ultra Seal A-30 in FSP VL sheet pile interlocks. This method is based on the assumption that the wall deflections, are such that the elastic line of the wall. They are opening the center interlock by lifting from the center. Two workers are filling the center interlock.
