METHOD TO MANUFACTURE BORED PILE AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC E02D5/42 

FIELD: construction.

SUBSTANCE: invention relates to construction and may be used for production of a bored pile. The method to produce bored piles in a well includes insertion of a shell into a well, supply of an explosive substance via the shell, connected to a source of electric current, supply of hardening material through the shell, closing of the shell hole. A fluid agent is supplied into the cavity of the shell formed by bend sections of the shell, afterwards they initiate ignition of the explosive substance. Then the hardening material is supplied into the well, after filling of the well with the hardening material the shell is moved reciprocally, and the hardening material is supplied into the well, afterwards the well is left until the hardening material hardens.

EFFECT: technical result consists in increased bearing capacity of a produced pile for action of vertical and horizontal loads, reduced material intensity.
