However, in Korean Patent Registration No. 1171414, "Expansion and expansion pipe device for water and sewage pipes" and a conventional expansion joint device or expansion pipe having a similar structure, the water pipe is formed by being expanded in the socket pipe, and a flange having a maximum outer diameter is formed in the water pipe. When the socket pipe is laid horizontally on the ground, the flange touches the ground and the load of the socket pipe is transmitted to the flange.If the socket pipe falls or an external force is applied, the load is transferred to the flange and the risk of damaging the enlarged water port is increased. have.

In addition, since the coupling groove for accommodating the elastic deformation is formed in the socket tube, the thickness of the socket tube of the coupling groove is reduced, there is a risk of damage, and the grip ring is moved in the width of the coupling groove or the gap between the engaging projections according to the expansion and contraction, If the step of the coupling groove or the engaging projection is low, there is a risk that the socket tube is detached from the grip ring. When the external force acts in the vertical direction of the tube, the external force is transmitted to the socket tube formed with the coupling groove or the engaging protrusion through the grip ring. There is a risk of breakage.

Therefore, in order to solve the above-mentioned problems, the present invention comprises a water and sewage pipe and a clamp, the water and sewage pipe includes a pipe main body and a protective socket, the protective socket is integrally formed on the outer periphery of the pipe main body, the protective socket A protective jaw protruding along the circumference is formed, and the clamp forms a tightening part inside the one side, and a release preventing jaw protruding from the inside of the other side, and forms a flow space inside the tightening part and the leaving preventing jaw. Fasten and fix it, and the flow space is formed as the space where the protective jaw is located so that the protective socket can flow. The anti-seizure protrusion protrudes inward than the outer diameter of the protective jaw but does not contact the outer diameter of the tube body. By connecting and clamping, the expansion and contraction in the flow space is allowed and the end of the water pipe is protected by a protective socket.

And the packing is in close contact with the outer periphery of the tube, the tube body is expanded to one side to form a first connection portion, the protective socket forms a second connection portion on one side, the first packing portion is the packing is fitted inward Forming a seat, the second connecting portion forms a second packing seat into which the packing is inserted inward, the outer diameter of the first and second connecting portion and the first and second packing seat is formed smaller than the outer diameter of the protective jaw, one end of the first connecting portion The protective socket is integrally formed on the outer circumference, and the tube is fitted to the inner circumference of the first and second connection portions, thereby preventing separation of the inserted tube and improving watertightness.
