FIELD: construction.
SUBSTANCE: method includes serial making of two rows of piles, the first one is made of bearing-cladding filling piles, which are arranged with gap, the second one is parallel in zone of the first row piles closure, at the same time in wells of the second row a monitor is serially installed with nozzles, through which gaps between piles of the first row are sealed by directed action of mortar jet. Piles of the first row are arranged with gap equal to 0.1-0.6 of their diametre and distance from axis of the first row piles to axis of piles of the second 0.5-1.0 diametre of the first row. Nozzles of monitor are arranged at the angle of 0°-90° to vertical axis of monitor and at the angle of 0°-180° in horizontal plane.
EFFECT: reduction of technological cycle, increased reliability and quality in development of tight antifiltration structure by creation of cement-soil element of non-cylindrical shape.
