MALE DIE FOR GROUTED PILES ESTABLISHMENT BY PRESSING METHOD OF ESTABLISHMENT GROUTED CONCRETE, REINFORCED CONCRETE AND FIBERCRETE PILES BY PRESSING BY MEANS OF GROUTED PILE ESTABLISHMENT WITH WIDENING, USING TREMIC ACCESSORY, MALE DIE Russian patent published in 2017 - IPC E02D5/34 

FIELD: construction.

SUBSTANCE: invention relates to construction, specifically to foundation engineering, and can be used in piled foundations establishment during construction of new and reconstruction of existing buildings and structures of different criticality rating. Male die for grouted piles establishment by means of piles pressing consists of strong hollow body, providing sufficient strength and rigidity, required to take up forces from pressing plant and soil resistance occurring during male die immersion with grouted pile establishment, tremic pipe, moving in strong hollow body and having two identical tremic holes with total area of 100 cm². Below tremic holes tip is rigidly fixed by means of fastening pin, which diameter is larger than tremic pipe diameter, but smaller than strong body diameter in form of drilling bit. Tremic pipe has limiter, due to which tremic pipe is limited in displacement inside strong body and remains in it during execution of works. Male die is made with forced movement of tremic pipe by means of drive or tremic pipe moves along strong body under its own weight.

EFFECT: technical result consists in improvement of works execution efficiency and quality, reduced labor intensity, material consumption and power consumption for establishment of grouted concrete, reinforced concrete and fibercrete piles.
