To form a bearing body of the front end section of an anchor of a compaction grouting in the shape of a bulb when a short anchor is required on the relation of a soft soil, a land or the like and to form a large friction bearing type anchor.

A bedrock 1 is bored by a casing pipe 10 through a boring machine 9, press-fit of a low slump compaction grout is made from the inside of the casing pipe 10, a bulbed body 14" formed in the shape of a cylinder having high frictional force of a self-hardening low slump is formed in the front end in a laminated state, the casing pipe 10 is inserted, a cement milk 14' is poured, at the same time, a tendon 15 is inserted, it is combined with the bulbiform body 14", and a single or a plurality of bulbiform bodies 14" is formed in a predetermined column state to make it possible to construct the short anchor on the relation of the soft soil having no anchor layer, the land or the like.
