Soldier Pile Wall With Concrete Lagging

Soldier pile retaining walls solider pile retaining walls and precast lagging panel systems are diverse and uniquely designed to suit a variety of situations addressing both the permanent and temporary earth retention and shoring requirements of your project.

Soldier pile wall with concrete lagging.

As excavation progresses in stages horizontal lagging in the form of timber or precast concrete is added behind the flanges to create the soldier pile and lagging wall. Wood lagging sometimes steel or concrete panels is placed between the soldier piles as excavation. Materials used for soldier piles and lagging walls the main component of these systems involves piles placed vertically at intervals with the lagging placed between for soil retention. Soldier pile wall consist of wide flange steel beams soldier piles and wood lagging.

The former is either forced into the ground to an adequate depth or installed into holes which are drilled in advance then encased in lean concrete to oppose or withstand the moment exerted by soil and the spacing is commonly between 1 8 m to 2 45 m. Lagging for soldier pile walls with and without permanent ground anchors shall be designed as either temporary or permanent based on the conditions described below. Soldier piles beams and lagging is an excavation support technique where vertical piles most commonly steel piles either driven or lowered into a drilled excavation and grouted are at regular intervals along the proposed wall location. This lagging can consist of metal decking rough sawn timber or precast concrete or sculpted shotcrete.

Lagging consisting of wood steel or precast concrete panels is inserted behind the front pile flanges as the excavation continues. Soldier piles are steel h piles that are vertically driven or drilled into the earth at regular intervals prior to excavation. Place the panel between the flanges of the soldier piles and bearing against the flanges on the exposed side of the wall so that the soldier pile flange overlaps the end of the lagging by at least one inch more than the concrete cover over the reinforcing steel at both ends of the lagging. Soldier pile walls have successfully being used since the late 18th century in metropolitan cities like new york berlin and london.

The geotechnical services branch will specify when lagging shall be designed for an additional 250 psf surcharge due to temporary construction load and which shall also be shown.
