(Prior art and its problems) Conventionally, the connection between a sewer pipe and a concrete wall such as a manhole has been made by connecting a connecting pipe to a hole drilled in the concrete wall, as proposed in, for example, Japanese Utility Model Publication No. 39018/1983. One end is inserted, and the flange protruding from the tube end is flush with the inner surface of the wall, and the annular protrusion bulged on the outer surface of the tube is set flush with the outer surface of the wall. A connecting pipe is fixed to the concrete wall by filling a space between it and the hole wall with a hardening material such as cement or mortar, and a sewer pipe is inserted and connected to the connecting pipe.

In the case of this mounting structure, since the outer periphery of the pipe between the flange protruding from the end of the connecting pipe and the annular protrusion is filled with a hardening material, the connecting pipe does not slip out from the concrete wall. However, although hardening materials such as cement and mortar bond firmly to concrete hole walls made of the same material, they do not blend well with the outer peripheral surface of connecting pipes made of different materials such as synthetic resin. When the curing material dries and hardens, it may shrink and peel off from the outer peripheral surface of the connecting pipe, and sewage inside the pipe may seep out through this short period of time.

Furthermore, an annular groove is provided on the inner periphery of the annular protrusion of the connecting pipe, and a sewer pipe is connected via a packing installed in the annular groove, but how far should the sewer pipe be inserted? Because there was no such positioning means, the ends of sewer pipes were sometimes left uninserted and connected. In such cases, sewage pipes sometimes slip out of the connecting pipes due to ground subsidence or ground movements such as earthquakes.

(Functions and Effects of the Invention) As described above, in the present invention, one end of the joint body is inserted into a hole drilled in a concrete wall such as a manhole, and the annular protrusion provided on the outer periphery is inserted into the concrete wall. A rubber ring was attached to the outer periphery of the tube located in the middle and close to the annular protrusion, and a bonding material such as cement or mortar was embedded between the outer periphery of the tube end and the hole wall for bonding. When it dries, it contracts and hardens while sandwiching both sides of the annular protrusion, and the annular protrusion reliably prevents the joint body from coming off. Also, when the bonding material such as cement or mortar dries and shrinks, the bonding material may peel off from the outer periphery of the pipe end and create a gap.
During this time, it is completely blocked by a rubber ring attached to the outer circumference of the tube. Moreover, the rubber ring is compressed and contracted when the bonding material is embedded, and when the bonding material dries and contracts, it elastically expands and restores itself, resulting in gaps on the outer circumferential surface of the rubber ring. Never. Therefore, there is no fear that the sewage inside the pipe will seep out along the outer peripheral surface of the joint body embedded in the concrete wall.

In addition, packing is attached to the annular grooves provided at both ends of the joint body, and the packing on the back side functions as a positioning means, so when connecting the sewer pipe by inserting it into the joint body, Inserting the pipe until the tip touches the packing on the back side will ensure a secure connection, completely preventing the pipe from slipping out due to ground subsidence or ground movements such as earthquakes.
