The excavation support system using cantilevered soldier piles is constructed by drilling circular holes in the ground, placing H-shaped steel sections (referred to as HP sections) in the holes and filling the holes with concrete. Before the HP sections are placed in the holes, extruded polystyrene (EPS) boards are glued to the front and back side of the outer flanges of HP sections. What is the
purpose of EPS boards?
What will be an ideal response?
The EPS boards allow stripping of the concrete covering the outer flanges of HP sections, which allows the attachment of welded wire reinforcement to HP sections.
