The Society of Heating, Air-Conditioning and Sanitary Engineers of Japan/rubber displacement absorption pipe joint

Attached document B, Figure 2 Usage example of underground piping entering a building

3) Usage example between an external basin and a building A cylindrical pipe joint (ground subsidence compatible model) is installed near the interface with the building on piping from a building to an external basin in soft ground or where subsidence is predicted in the future. Usage example to an external basin and a building is shown in attached document B, Figure 3.
