In the main parts of the main pipe, pipes (PDS), 90 ° elbows (PDE 90 °), 45 ° elbows (PDE 90) in the form of injection moldings or secondary processed products are used to connect pipes to each other or to fix members such as manholes. °), T-shaped tee socket (PDT) and the like.

Since these fittings are connected to the ends of the main pipe by inserting method, whenever the installer branches another pipe member at the desired place, it is very inefficient to perform the joining work after cutting in consideration of the pipe length. At the same time, the amount of use is large, which is uneconomical.

Therefore, in consideration of such various problems, in actual pipe construction site, a hole having a predetermined diameter is drilled in the main pipe (or main pipe), and then the branch pipe is connected from the main pipe by mounting or mounting a branch hole (or a fastening pipe). have.

In general, if branch outlets are not used for the connection of sewer pipes, problems such as closure of the main pipes may occur when the branch pipes are excessively inserted into the main pipes. Problems such as leakage and inflow of groundwater may occur when miscontact or the like occurs.

Conventional technologies related to branching outlets include branch branch socket attachment devices, fastening pipe connection clamps, branch sewer pipe joints of main sewer pipes, pipe fastening pipes, connecting members of main sewer pipes and branch sewer pipes, watertight distribution mechanisms for PVC DC, DC Cast iron pipes for watertight connections, mortar concrete forks (C / T).
