Methods for the construction of lowered structures and pile foundations

The paper discusses the methods of erecting sunk wells and pile foundations, which consist in regulating frictional forces soils: lowering along lateral surface when sinking increasing foundations. developed method provides for application two types effective antifriction coatings surface: cutting edge structure above ledge. At same time, coefficients reducing friction by these various soils have been established, a calculating is proposed, taking into account use submerging method. To increase on driven piles to their bearing capacity, modular with T-section introduced. areas rational are established depending (clay sandy) depth penetration.
