ABSTRACT:
An excavator for constructing an underground continuous wall includes an extensible guide post, an endless chain extending around a chain driving wheel provided at the upper portion of the guide post and a chain sprocket at the lower portion of the guide post, and a number of cutter bits and a number of agitator bars alternately arranged on the chain to form an endless chain cutter and a jet pipe provided in the guide post to be connectable to a fluid supply source and having a number of nozzles branched from the jet pipe. The endless chain cutter is detachably fixed to the end of the boom extending from a vehicle traveling on the ground. The endless chain cutter may be vertically movably mounted on the boom so as to be vertically driven by a driving device. The cutter bits are changeable with harder cutter bits according to obstacles in the ground.
