  2. Pile driver - Wikipedia

    en.wikipedia.org/wiki/Pile_driver

    A pile driver is a heavy-duty tool used to drive piles into soil to build piers, bridges, cofferdams, and other "pole" supported structures, and patterns of pilings as part of permanent deep foundations for buildings or other structures. Pilings may be made of wood, solid steel, or tubular steel (often later filled with concrete), and may be ...

  3. Piling - Wikipedia

    en.wikipedia.org/wiki/Piling

    Splicing timber piles is still quite common and is the easiest of all the piling materials to splice. The normal method for splicing is by driving the leader pile first, driving a steel tube (normally 60–100 cm long, with an internal diameter no smaller than the minimum toe diameter) half its length onto the end of the leader pile.

  4. Wave equation analysis - Wikipedia

    en.wikipedia.org/wiki/Wave_equation_analysis

    The soil response for each pile segment is modeled as viscoelastic-plastic. The method was first developed in the 1950s by E.A. Smith of the Raymond Pile Driving Company. Wave equation analysis of piles has seen many improvements since the 1950s such as including a thermodynamic diesel hammer model and residual stress. Commercial software ...

  5. High strain dynamic testing - Wikipedia

    en.wikipedia.org/wiki/High_strain_dynamic_testing

    It is codified by ASTM D4945-12 - Standard Test Method for High-Strain Dynamic Testing of Piles. High strain dynamic testing is called dynamic pile monitoring when it is applied during pile driving and dynamic load testing when it is applied following pile installation, regardless of the installation method.

  6. Franki piling system - Wikipedia

    en.wikipedia.org/wiki/Franki_Piling_System

    Franki piles can be installed raked (or sloped) with a tilt of up to 4:1. [5] Raked Franki piles are always reinforced and are particularly suitable for structures subject to dynamic forces. [1] Driving methods such as open-ended coring, rock socketing, and composite shaft construction are occasionally used to overcome unique site problems. [3]

  7. Pile integrity test - Wikipedia

    en.wikipedia.org/wiki/Pile_integrity_test

    Pile integrity testing using low-strain tests such as the TDR (Transient Dynamic Response) method, is a rapid way of assessing the continuity and integrity of concrete piled foundations. The test measures: pile length, or depth to anomalies; pile head stiffness; pile shaft mobility, which is dependent on pile section and concrete properties

  8. Danish pile-driving formula - Wikipedia

    en.wikipedia.org/wiki/Danish_pile-driving_formula

    The Danish pile-driving formula is a formula which enables one to have a good gauge of the bearing capacity of a driven pile. History The formula was constructed by ...
