The present invention relates to a corrugated steel pipe end insertable connection structure, and more particularly, to a corrugated steel pipe end insertable connection structure in which a corrugated steel pipe is arranged so as to be sandwiched in a longitudinal direction by a plug portion as a fitting portion formed at one end portion and a receptacle portion as a fitting portion formed at the other end portion, As shown in FIG.

In general, corrugated steel pipes are used as wastewater drainage, domestic water or industrial water supply and hollow formwork, and provide high external pressure strength, structural stability, durability, economy, and workability.

In the field of civil engineering, corrugated steel pipe is used for drainage of domestic sewage, factory wastewater or enriched sewage water, drainage of large-scale public facilities or mariculture grounds, golf course, sports facility or complex ladder town or road, agricultural water or industrial water . The corrugated steel pipe is also used as a hollow formwork or building suit for the construction of buildings or bridges in the field of construction.

The corrugated steel pipe is produced by making the galvanized steel sheet have a corrugated shape by a molding operation and then cutting the corrugated steel pipe to an appropriate length. In the manufactured corrugated steel pipe, the corrugated steel pipe on one side and the corrugated steel pipe on the other side are butted against each other The gasket or the O-ring is connected to the gasket, and the coupling having the gasket is wrapped around the gasket, so that the watertightness is continuously maintained.

However, in the corrugated steel pipe joined by such coupling, the ends of the corrugated steel pipe are simply butted against each other, so that when the axial pressure acts, the corrugated steel pipe of one side and the corrugated steel pipe of the other side There was a problem of warping.

In addition, when a separate flange is provided at the end of each corrugated steel pipe, there is a great difficulty in connection with the corrugated steel pipe having an outer peripheral edge in the form of a mountain and a valley.

In addition, since the corrugated steel pipe on one side and the corrugated steel pipe on the other side are simply enclosed by the coupling, it is difficult to center the corrugated pipe during the construction process. As a result, the time required for the operation is delayed, .
