Objectives:

  • enhancement of strength and deformation characteristics of highly compactable plastic EGE-5 soils in the underlying layer, from the base of the foundation, increase of soil deformation module values E from 6.2 MPa to 19 MPa; values of soil cohesion Cn from 17 KPa up to 23 KPa.
  • balancing of physical and mechanical characteristics of soils at the base of foundations;
  • prevention of settlement of foundations and basements above allowable level by reinforcement of highly compactable plastic EGE-5 soils in the underlying layer, from the base of the foundation.

Solution:

Works on reinforcement of soils by the method of pressure injection cementation. Considering the local engineering-geological conditions of the construction site, the foundation soils were reinforced according to the following construction procedure: solid reinforcement with injectors to the given depth – from -11.600m up to -16.600m (abs.el.); from the bottom of the construction pit +24.90m abs.el. (-3.900 rel.el.).

Year of performance: August 2013
