FIELD: development of soil.
SUBSTANCE: : devices for the development of soil in tight conditions. Earth-moving working body contains a wall attached to the handle of the excavator, two bits rigidly fixed on the lower edge of the wall at an equal distance from its side edges and from each other, a pendulum gripper movably mounted on hinges fixedly attached to the lower part of the wall, a cutting edge, rigidly fixed on the wall under the hinges, two flexible links attached to the side ribs of the wall and to the upper part of the pendulum grip. The wall is made with the possibility of interaction with the guide piles buried along the outer surface of the underground structure.
EFFECT: simplification of the design of the working body and an increase in the safety of excavation in tight conditions.
