Abstract
The present invention relates to a connection structure of a corrugated steel pipe end insertion type.
To this end, the present invention is a corrugated steel pipe end insertion type connection structure in which one end portion of a corrugated steel pipe having a helical shape is fitted and connected to the other end portion, wherein one end portion and the other end portion of the corrugated steel pipe have a ring- Wherein the plug corrugated tube is formed at one side end of the corrugated steel tube and the plug corrugated tube is formed to extend outward at one end of the corrugated steel tube, And the receptacle portion is formed so as to extend outward at the end portion of the steel pipe, and the receptacle portion is formed such that the receptacle bone steel pipe extends outward at the other end portion of the corrugated pipe, and the receptacle pipe is extended outward .
Therefore, the present invention can prevent the wavy corrugated tubes from spreading after the construction, so that the life of the corrugated steel pipe can be easily extended while the center of the corrugated steel pipe can be easily made, and the time And reduce the construction cost accordingly.
Description
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, .
The present invention can prevent warpage and leakage phenomenon by preventing the one corrugated steel pipe and the other corrugated steel pipe from spreading after construction, and completely solves the problem that the connection portion is dropped when a biased earth pressure is generated, The construction work of the corrugated steel pipe can be easily performed in the field, and the time required for the construction work and the construction cost can be reduced.
The present invention relates to a corrugated steel pipe end insertion type connection structure in which one end portion of a corrugated steel pipe (10) having a spiral shape is fitted and connected to the other end portion, wherein one end portion and the other end portion of the corrugated steel pipe (10) The

In the present invention, the plug corrugated steel pipe and the plugged corrugated steel pipe are formed in the coupling band in a state in which the corrugated steel pipe on one side and the corrugated steel pipe on the other side are inserted at a predetermined depth to each other by the fitting portion composed of the plug portion and the receptacle portion, The pressurized portion and the pressurized portion of the receptacle steel plate are kept pressed to prevent the wavy corrugated pipe from being opened after the application and to fully compensate the problem that the connection portion is removed when the biased earth pressure is generated, It is possible to obtain an effect that can be extended.
In addition, it is possible to obtain an effect of preventing the warped shape of the portion where the corrugated steel pipe is connected.
In addition, it is possible to further prevent leakage of water generated through the corrugated steel tubes.
Further, it is possible to obtain an effect that the operation of matching the centers of the corrugated steel tubes with each other can be facilitated.
As a result, the time required for the construction work as a whole can be reduced, and the construction cost can be further reduced.
