Sheet pile must be exercised to see that the FLP 700/8 or FLP 750/8 does not settle after construction. More is not always better! The most efficient amount is slightly less then the measured gap when the male / female interlocks are fully extended. The success of these gauges depends highly on KD400/6 surface preparation, bonding, and waterproofing. For example if the measured gap is 1/8", the depth of trench sheet KD 400/6 should be slightly less than 1/8". This is generally not a problem in undisturbed soils, however, where the anchorage must be located in unconsolidated fill, piles may be needed to support the trench sheeting blocks.Apply the A-30 - use a FLP750/8 small brush or spatula to help FLP 750/8 spread the A-30. Measure depth carefully. Field tests have shown that these gauges, when properly installed and protected, will survive pile driving. Continuous Deadmen Near Ground Surface - A continuous deadman is shown in KD600/6. The active and passive pressure distributions for granular and cohesive soils. Apply in the KD 600/6 female socket (non - leading side). IMPORTANT - Must have correct amount in the interlock. Determine this measurement before mixing.

The correct trench sheet depth of A-30 is important for KD 400/6 or KD 600/6 or KD 600/8. For design in cohesive soils, both the immediate and the long-term pressure conditions should be checked to determine the critical trench sheeting case. A safety factor of two against failure is recommended; i.e.,Determine the volume required for that length of interlock. You can treat remaining pile by calculated volume if desired however keep checking depth periodically. Short Deadmen Near Ground Surface -KD 600/8 deadman of length, L,located near the ground surface, subjected to an anchor pull, T. Experiments have indicated that at the time of failure, due to KD600/8 edge effects, the heave of the trench sheets ground surfaces takes place in an area as shown. The surface of sliding at both ends is curved. Short deadmen near ground surface (after Teng1) c. Data collection and presentation. Initial FLP700/8 readings should be made on all sheet piling instrumentation subsequent to installation, so that an initial data base is established. Also, the FLP 700/8 soil within the passive wedge of the anchorage should be compacted to at least 90 per cent of maximum density unless the deadman is forced against firm natural soil.

The frequency of trench sheets should depend on KD400/6 and KD600/6 and KD600/8. An established monitoring schedule and should escalate during critical loading conditions or increased wall deflections. To help lubricate the pile just prior to driving, use a brush dipped in soapy water and brush the interlock when the pile is being picked up to drive. After driving has started and the pile has hit water (ground water - standing KD600/8 water), the FLP700/8 pile must reach its final depth within 2 hours. Profiles and alignments are typically collected on a trench sheet yearly basis, while electronic devices should be read more KD600/8 frequently. Weather conditions and any apparent deformities at the site should be recorded. Piles must be driven with the untreated interlock leading. Drive treated interlock over untreated interlock. Data should be processed and evaluated by qualified personnel and reviewed by higher authority.

Integration of the resistance sheet pile along these curved sliding surfaces results in the following expression for the ultimate capacity of short deadmen in granular soils. After A-30 is cured (firm) the pile can be moved to a dry storage area. Protect KD 600/6 from moisture prior to driving. N. K. Ovesen50 conducted 32 different model tests in granular soil and developed a procedure for designing FLP750/8 anchor trench sheets slabs located in a zone where the anchor resistance can be fully mobilized. FLP 700/8 Piles must remain in level position until A-30 cures (becomes firm enough that it cannot be displaced when pressed with finger tips). Data should be displayed graphically so that various relations and trends can be readily seen.

FLP700/8 and FLP750/8 considers that the earth pressure in front of the slab is calculated on the basis of a rupture surface corresponding to a translation of the slab. If covering with plastic sheet, invert pile so condensation does not collect in the interlock. The person collecting the data should be experienced with the instrumentation devices in KD 400/6 trench sheets use. This method can be used to solve the general case for rectangular anchors of limited height and length located at any KD600/6 depth. Piles can be stored for several sheet piles weeks if protected from moisture and direct FLP 750/8 sunlight. Surface loads behind the anchor slab are not included in this publication since their influence is small on the anchor resistance for granular KD400/6 soils with an angle of internal friction equal to or greater than 30 degrees.
