Secant concrete shoring using helical piles for depth
A pile shoring wall includes tangent concrete piles that are formed in the ground at an excavation site. The tangent concrete piles include a plurality of a first type of concrete piles in the ground at depths wherein the average depth is d1 and a plurality of a second type of concrete piles. The second type of concrete piles includes 10% and less than 50% of the tangent concrete piles, and each have a shaft of a helical pile secured therewithin. Each helical pile has a bottom portion with helical flights for screwing the helical pile into the ground, and each helical pile is set into the ground to a depth of at least about 2 m below d1. The helical flights of each helical pile are exposed to the surrounding soil and increase resistance below an excavation depth when the site is excavated.
