FIELD: bulkheads or similar walls made solely of concrete in situ, particularly curtain or trench wall.
SUBSTANCE: method for cast-in-place trench wall erection in ground 3 to permit barrier 1 passage through the wall involves excavating side holes 52, 51 for wall erection from both sides of the barrier 1; digging-out lower hole 60 for wall erection under the barrier by soil-shifting machine movement in lateral direction from at least one side hole 51, 52, wherein hole 51, 52, 60 excavation is carried out along with loosened ground mixing with binding agent inside or outside the holes to obtain hardening suspension. Soil-shifting machine is milling slot-cutting device 10. The trench wall permits barrier passage through the wall.
EFFECT: increased economical efficiency and decreased time for trench wall erection.
