  2. Pile driver - Wikipedia

    en.wikipedia.org/wiki/Pile_driver

    Pile driver, 1917. Ancient pile driving equipment used human or animal labor to lift weights, usually by means of pulleys, then dropping the weight onto the upper end of the pile. Modern piledriving equipment variously uses hydraulics, steam, diesel, or electric power to raise the weight and guide the pile.

  4. Tripod (foundation) - Wikipedia

    en.wikipedia.org/wiki/Tripod_(foundation)

    Since the new century, there has been a search for a feasible foundation for the upcoming large turbines and greater water depths, in light of the available geotechnical assessment methods, fabrication processes, pile driving equipment and logistic and installation equipment. One result was the Tripod foundation.

  5. Deep foundation - Wikipedia

    en.wikipedia.org/wiki/Deep_foundation

    Hydraulic hammer is removable working equipment of hydraulic excavators, hydroficated machines (stationary rock breakers, loaders, manipulators, pile driving hammers) used for processing strong materials (rock, soil, metal) or pile driving elements by impact of falling parts dispersed by high-pressure fluid.

  6. High strain dynamic testing - Wikipedia

    en.wikipedia.org/wiki/High_strain_dynamic_testing

    These sensors are connected to an instrument (such as a pile driving analyzer), that records, processes and displays data and results. As long as the wave travels in one direction, force and velocity are proportional and related by the expression F = Zv, where: Z = EA/c is the pile impedance; E is the pile material modulus of elasticity

  7. Wave equation analysis - Wikipedia

    en.wikipedia.org/wiki/Wave_equation_analysis

    The model mathematically represents the pile driving hammer and all its accessories (ram, cap, and cap block), as well as the pile, as a series of lumped masses and springs in a one-dimensional 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 ...

    en.wikipedia.org/wiki/Bubble_curtain

    Pile driving in connection to offshore construction, most importantly monopile foundations for offshore wind turbines, produces very high levels of underwater noise, [3] capable of inflicting damage to the hearing of marine organisms [11] and deter animals at tens of km from the construction site.

  9. Franki piling system - Wikipedia

    en.wikipedia.org/wiki/Franki_Piling_System

    A Franki pile. The Franki piling system (also called pressure-injected footing) is a method used to drive expanded base cast-in-situ concrete (Franki) piles. [1] It was developed by Belgian Engineer Edgard Frankignoul in 1909.
