The present invention relates to a sewage pipe connection structure, and more particularly, when the sewage pipes are continuously / repeated to be in contact with each other, the sewage pipes and the sewage pipes moving along the sewage pipes by closely connecting the connection portions through circular rings. The present invention relates to a sewer pipe connection structure having a tight coupling to prevent the wastewater from leaking through the connection part.

In general, concrete sewage pipes are buried underground in sewage generating areas such as industrial sites and homes, so that sewage, wastewater, or chemical water flows into the purification facilities, or drains rainwater and agricultural industrial water into rivers. .

Such a sewer pipe is a pipe made of reinforced concrete made by uniformly spraying concrete using centrifugal force. The pipe is squeezed in advance to form a steel tube, and the pipe is rotated at high speed. After putting the appropriate amount of concrete inside, it is manufactured by spraying the pipe on the inner wall of concrete with uniform thickness by centrifugal force by rotation.

1 is a perspective view showing the structure of a conventional sewer pipe.

Referring to FIG. 1, the conventional sewer pipe 10 has an insertion portion 30 having an inner diameter larger than that of the main body 20 at one end of the main body 20 having a hollow tube shape. Accordingly, when the sewer pipe 10 is installed on the ground, one side of the outer circumferential surface of the main body 20 is inserted / connected to the inner circumferential surface of the insertion portion 30. The sewage pipes having such a connection relationship are continuously / repeated to be in contact with each other, so that sewage, waste water, or chemical water can be drained through the sewer pipe 10.

At this time, the insertion part 30 has a pedestal function that supports the sewer pipe 10 when the sewer pipe 10 is grounded to the ground.

The sewer pipe 10 configured as described above connects a plurality of sewer pipes 10 into the ground so as to serve as the sewer pipe or the drain pipe when the sewer or drain pipe is constructed.

However, such a conventional sewage pipe had the following problems in the connection portion when buried in the ground.

That is, the material moving through the sewer pipe is a liquid material (sewage, sewage / waste water) is moved, the connection between the inner peripheral surface of the insertion portion and the outer peripheral surface of the body when the sewage pipe is continuously / repeatedly connected There is a problem that the sewage and waste / waste water moving through the connection portion is leaked because it does not achieve intimate surface contact.

In addition, even if a small impact is applied to the ground in which the sewer pipe is buried, there is a problem that the connection part is distorted and settlement occurs in the sewer pipe at the site where the impact is applied.

The present invention has been made in view of the problems of the conventional sewage pipes and its purpose is to form a plurality of circular insertion grooves on one side outer circumferential surface of the body, and to insert / connect a circular ring to the circular insertion grooves so as to contact the sewer pipes with each other. In the case of continuous / repeated connection, the inner circumferential surface of the insert portion and the outer circumferential surface of the main body have a close connection, so that tight coupling can be prevented in advance to prevent leakage of sewage and waste water moving along the sewer pipe through the connection part. Provides a sewer pipe connection structure having a.

In addition, another object of the present invention by connecting a separate sedimentation prevention to the outer peripheral surface of the main body so that the sewer pipe can be firmly supported on the ground through the subsidence prevention, the external impact on the ground the sewer pipe is embedded It provides a sewer pipe connection structure having a tight coupling that can prevent the sewage pipe sinking even if it occurs.
