About IPS

We introduce the IPS System of Supportec Co., Ltd.

Design

  • Check the depth of excavation
    Assume layers and position

    Check earth pressure of each
    layer by the excavation depth

    Plan design of IPS

  • Consider the location of the slab of
    the structure in sectional view

    Use earth pressure analyzing
    Program such as SUNEX, Geo-X

  • Plan of IPS Wale

    1. Install 10-15cm apart from the wall (Consider backfilling space)

    2. Check minimum space of non
    reinforced wale

    3. Decide the length of IPS wale
    by earth pressure

  • Plan of Strut

    1. Design by load distribution width of earth pressure

    2. Check column number of strut
    by earth pressure

    3. Design considering preloading
    (Check the number of preloading jack)

  • Plan of Post Pile

    1. Post Pile arrangement considering strong axis buckling

    2. Cover plate arrangement considering weak axis buckling

    3. Design considering interference of column and beam

    4. Design strut and other stiffener
