TEST BENCH FOR SIMULATION OF GROUND BASE DEFORMATION IN THE CASE OF ADJACENT AREA LOADING Russian patent published in 2007 - IPC E02D1/00 G01N33/24 

FIELD: construction, particularly test devices to investigate deflected mode of building and building structure ground foundation base.

SUBSTANCE: test bench comprises container with ground sample, loading frame and measuring system for ground sample surface loading and movement. The container is made as tray fixedly connected with loading frame. The loading frame includes three members and guiding beam and is provided with two dies, namely rigid one and one having finite rigidity. The die having finite rigidity is made as sealed chamber with plates installed in lower chamber part so that the plates are spaced therefrom and may move in vertical direction. Rubber envelope connected to hydrostatic pressure source and standard manometer supported by die lid is installed inside the chamber. The die having finite rigidity is connected to loading frame by means of pads to provide movement thereof along guiding beam in horizontal plane.

EFFECT: increased test bench capabilities, possibility to estimate existent building foundation base deformation influence on neighboring new one under construction in dependence of load and distance between the buildings.
