  2. Screw piles - Wikipedia

    en.wikipedia.org/wiki/Screw_piles

    Modern screw pile design is based on standard structural and geotechnical principles. Screw pile designers typically use their own design software which has been developed through field testing of differing compression pile and tension anchor configurations in various soil profiles. Corrosion is addressed based on extended field trials ...

  3. Offshore embedded anchors - Wikipedia

    en.wikipedia.org/wiki/Offshore_embedded_anchors

    The figure shows the different installation methods, where in the "driven" method, the steel tube is driven mechanically by a hammer, whilst in the "drilled" method a cast in-situ pile is inserted into an oversized borehole constructed with a rotary drill and then grouted with cement. Employment of a particular method depends on the geophysical ...

  4. Pile driver - Wikipedia

    en.wikipedia.org/wiki/Pile_driver

    The most common form of pile driver uses a heavy weight situated between vertical guides placed above a pile. The weight is raised by some motive power (which may include hydraulics, steam, diesel, electrical motor, or manual labor). At its apex the weight is released, impacting the pile and driving it into the ground. [1] [3]

  5. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  6. Tieback (geotechnical) - Wikipedia

    en.wikipedia.org/wiki/Tieback_(geotechnical)

    Upon installation, tiebacks are tested and usually pre-loaded. In specific, a combination of proof tests and performance tests are performed on every job. Proof testing involves the application of successively larger loads on the tieback with a loading jack, allowing for the recording of a load-elongation curve according to gauge readings.

  7. Keras - Wikipedia

    en.wikipedia.org/wiki/Keras

    Keras is an open-source library that provides a Python interface for artificial neural networks. Keras was first independent software, then integrated into the TensorFlow library, and later supporting more. "Keras 3 is a full rewrite of Keras [and can be used] as a low-level cross-framework language to develop custom components such as layers ...

  8. Larssen sheet piling - Wikipedia

    en.wikipedia.org/wiki/Larssen_sheet_piling

    Larssen sheet piling is a kind of sheet piling retaining wall. Segments with indented profiles (troughs) interlock to form a wall with alternating indents and outdents. The troughs increase resistance to bending. The segments are typically made of steel or another metal. [1]

  9. Driven to refusal - Wikipedia

    en.wikipedia.org/wiki/Driven_to_refusal

    This is an engineering term for describing how far to drive piles. [1] It is also used in surveying when driving metal posts and monuments that are to be used as bench marks (ie. the elevation of which will be established to a high degree of accuracy).
