METHOD TO TEST BEARING CAPACITY USING CIRCULAR SENSOR (VERSIONS) Russian patent published in 2012 - IPC E02D33/00 

FIELD: construction.

SUBSTANCE: method to apply load to a pile, where an upper part is placed below the first pile section, at the same time the upper part is fixed to the first pile section. A bottom part is placed near the upper part, at the same time an area of separation is developed so that introduction of fluid medium under pressure into the separation area provides for a force striving to move the upper part and the bottom part from each other, and causes upward movement of the upper part in the first pile section. At least a part of a cross section in the upper part and at least a part of a cross section of the bottom part is open to ensure passage of materials on top from the upper part to the bottom from the bottom part. The upper part and the bottom part are placed prior to pile casting, at the same time materials for pile casting go through the open part of the cross section of the upper part and the open part of the cross section of the bottom part. If the upper part and the bottom part are separated, the upper part and the bottom part preserve their relative side position during separation, and the fluid medium is introduced into the separation area to apply the load to the pile.

EFFECT: reduced material intensity and labour intensiveness when testing higher bearing capacity of a pile.
