This type of spear socket is a type of pipe joint, and is used, for example, in the following cases. That is, Fig. 3 shows a cross-sectional view of a general sewage pipe installation. Sewage or rainwater basins 4, 4 are provided under the shaped side gutters 3, 3, and the main pipe 2 and the basins 4, 4 are connected via attachment pipes 5, 5. This installation pipe 5
is composed of ceramic pipes, reinforced concrete pipes, vinyl chloride pipes, etc., but if the main pipe 2 is a reinforced concrete pipe, attach a ceramic socket and connect the bent pipe 6 from there.
and connect to the tubes 4 and 4 via the straight pipe 7. Furthermore, if the main pipe 2 is a vinyl chloride pipe, a branched pipe 8 must be used as the attached pipe 5.

ため、ヤリトリソケツトを使用している。 When a part of the attached pipe 5 is damaged during such pipe installation, only the damaged part is cut off and removed, and replaced with a new synthetic resin pipe. In such a case, since the main pipe 2 and the sewage or rainwater basin 4 are fixed as they are, each end of the existing attached pipe 5 that is being extended is also fixed, so it is necessary to install a new synthetic pipe to intervene. Connection with resin pipes is not easy. Therefore,
A spear socket is used to connect the end of the existing installation pipe 5 to the new pipe.

Therefore, this invention was devised to solve such problems, and its gist is as follows:
It consists of an outer tube made of synthetic resin and an inner tube made of synthetic resin that is fitted into the outer tube and is substantially polymerized, and these inner and outer tubes are sealed to the outer periphery on the upstream side of the outer tube. At the same time, an annular groove into which an O-ring is fitted is formed to bulge out, and the downstream side of the outer tube is made to have the same diameter as the insertion port, while a funnel-shaped enlarged diameter portion is formed at the upstream end of the inner tube. Among these:
When the outer tube is polymerized, it is composed of the total length of the outer tube and the axial length of the funnel-shaped enlarged diameter section, and the funnel-shaped enlarged diameter section is
The ends of fixed pipes of different types, such as humid pipes or ceramic pipes, are filled with mortar and are fitted externally and in contact with each other, and a ring that fits internally into the inner pipe and the funnel-shaped enlarged diameter part A sewage pipe spear socket is characterized in that a stopper made of synthetic resin is provided at the upstream end of the inner pipe, and a stopper made of synthetic resin is integrated with a small enlarged diameter portion joined to the base side of the pipe.

Since the lengths of the inner and outer tubes are the same, when they are superimposed, they can be constructed into a short length consisting of the total length of the outer tube and the axial length of the funnel-shaped enlarged diameter portion, making it easy to carry into the narrow space to be repaired. Can be done. At this time, a stopper matching the diameter of the fixed pipe, such as the humid pipe, exposed by excavation is fitted into the inner pipe. Therefore, a funnel-shaped enlarged diameter part made of synthetic resin was fitted onto and abutted on the end of a fixed pipe such as a fume pipe, and then the space formed by this funnel-shaped enlarged diameter part and the fixed pipe was filled with mortar. Then slide the downstream side of the outer tube and pull it out.
Insert into the socket of another synthetic resin pipe and backfill.
