FIELD: mining and building, particularly bulkheads or similar walls made of prefabricated parts and concrete, including reinforced concrete, in situ. ^ SUBSTANCE: device comprises frame, at least one lower milling/mixing disc cutter arranged from frame bottom and at least one additional, upper, milling/mixing disc cutter installed from frame top. Central frame part between upper and lower milling/mixing disc cutters has cross-section less than milling cross-section of at least one lower milling/mixing disc cutter. Milling device for barrier wall erection comprises frame, two adjacent lower milling/mixing disc cutters arranged from frame bottom and two adjacent upper milling/mixing disc cutters installed from frame top. The upper and lower milling/mixing disc cutters are brought into rotation by means of rotary drive. Milling device is immersed in ground and as final depth is achieved the milling device is removed from ground, wherein both upper milling/mixing disc cutters and both lower milling/mixing disc cutters rotate in opposite directions by means of rotary drive. ^ EFFECT: increased quality of barrier walls. ^ 15 cl, 5 dwg |
