The excavation pits.
The excavation pits
In a study carried out excavation of foundations pits the walls and pillars of the basement or first floor of the building. At considerable depths of the foundations of the walls carried fixture pits.
Determination of depths of foundations and piles of geophysical methods
Seismic measurements are conducted computerized digital seismic station "Diogenes 03/12 № 20/2000» using geophones, and the excitation of oscillations of light hammer blows carried out. The intensity of the reflected wave is also being evaluated for the contact "a foundation-ground."
Determination of strength characteristics for foundations
Strength figures laying the foundation determined by NDT methods that implement the methods rebound. For nondestructive tests of concrete by mechanical methods the Schmidt device of type N (production of Proceq SA firm, Switzerland) is used.
