FIELD: construction.
SUBSTANCE: in a drilled well under a building or a structure, or in the vicinity thereof, a high pressure hose is set, muffled at one end and connected to the hydrostatic generator with the other end. Adjustable vibro pulse impact on the ground under the building is created by changing the working fluid pressure supplied to the high pressure hose. Oscillations of the building or the structure are recorded by three-component vibration sensors installed near the tested object or inside it. The conclusion on the physical condition of the building or the structure is carried out by comparing the measured dynamic characteristics of the building or the structure before and after the vibro pulse impact.
EFFECT: improved assessment accuracy of the physical condition of the building or structure under vibro pulse impact on the surrounding ground.
