  • Excavation support structure
    Patent number: 5934840
    Abstract: An excavation support structure has a vertical face and includes an array of two or more soil-cement columns positioned internal to the vertical face. The columns are positioned within the array so that each of the columns is not connected by soil-cement to any other column. Soil surrounds the soil-cement columns except where the soil-cement columns meet the vertical surface. The soil-cement columns are distributed within the support structure so as to form a composite structure with the soil.
