METHOD OF ARRANGEMENT OF ENCLOSURES FROM SECANT BORED PILES Russian patent published in 2019 - IPC E02D5/20 

FIELD: construction.

SUBSTANCE: invention relates to construction of protective structures to combat landslide phenomena at gas transportation system facilities and other industrial infrastructure. Method of arranging fences of secant bored piles includes wells for leading and crossing piles and reinforcement frames. Method proposes to use casing pipes with longitudinally concave surfaces for advanced piles; at that, concave surfaces of adjacent casing pipes installed in pre-drilled wells serve as guides when drilling wells for crossing piles, which excludes rock collapse and removal of drilling tool to side. Further, into the drilled wells under the crossing piles, reinforcement frames are installed, which are fixed by means of welding to the casing pipes with longitudinally concave surfaces by bridges. Assembled structure is poured with concrete to form a guard.

EFFECT: technical result consists in ensuring high quality of works when making barriers from secant bored piles, preventing rock collapse and removal of drilling tool to side.
