Tamped-trench foundation construction in Leningrad
Conclusions The experience with tamped-trench foundation construction has shown that this method can be successfully used not only in water-saturated clays, ordinary loams, sandy loams, and fills, but also in sands and gravel-sand soils. The investigations showed that in water-saturated fine silty sands, the addition of a small quantity of clay and rubble during the tamping process forms a smooth trench capable of standing during 3–6 h without wall collapse or penetration of water into it under the full hydrostatic pressure. Construction of a widened base by tamping rubble increases the possible load on the foundation by a factor of 1.6–3.The use of foundations in tamped trenches instead of individual column footings, or pile foundations makes it possible to reduce the labor by a factor of 3–5, the earthwork by 90–100%, the concrete and steel by 15–50%, and the construction cost by 50–60%. Also, formwork and dewatering are eliminated, the transportation costs are lowered, the quality of the floor bases as well as of the equipment foundations is improved, and it is not necessary to compact backfills.
