The present invention provides a casing guide apparatus for a ground excavator, wherein an apparatus is provided with a casing guide pipe to guide an insertion of a casing to increase the straightness of the casing and increase a working speed by simultaneously constructing two casings at a time. A casing guide apparatus for a ground excavator to guide a casing to form a continuous wall in a state of being inserted in the ground includes: a guide body with a space being formed on a center; two casing guide pipes inserted in the space at given intervals, and guiding vertical insertion of the casing; and a displacement preventing rail extending from both sides of the circumferential surfaces of the casing guide pipes, and fitted in the rail guide grooves formed on the inner surface of the guide body to prevent displacement of the casing guide pipe. |
