Tuojin earthquake-resistant photovoltaic pipe gallery support

Why are earthquake-resistant pipes so important in Japan?

The importance of earthquake-resistant pipes in Japan was highlighted by the Kobe Earthquake in 1995. Following this event, the ratio of earthquake-resistant pipes among all ductile iron pipes increased significantly, from approximately 80% the year after the launch of GENEX to around 95% in 2017.

Are ductile iron pipes earthquake-resistant?

Ductile iron pipes have proven their outstanding performance in numerous earthquakes without damage. The origin behind the development of the S-type joint, the first of these earthquake-resistant joints (the mechanisms for connecting pipes), was the 1964 Niigata earthquake, which registered a magnitude of 7.5.

Is Kubota ductile iron pipe earthquake resistant?

This earthquake-resistant ductile iron pipe (NS-type, 200mm nominal diameter) was exposed after a road collapsed in the tsunami caused by the Great East Japan Earthquake. No fragments or damage were found, proving the pipe’s outstanding seismic resistance. The Kubota spirit is faithfully being handed down to young engineers.

Are ground mounting steel frames suitable for PV solar power plant projects?

In the photovoltaic (PV) solar power plant projects, PV solar panel (SP) support structure is one of the main elements and limited numerical studies exist on PVSP ground mounting steel frames to be a research gap that has not be addressed adequately in the literature.

Does seismic action affect horizontal displacement of pipe gallery structure?

The horizontal displacement in corner of pipe gallery structure is larger than that at other positions, but the value is relatively small, indicating that the seismic action has no evident influence on the horizontal displacement of the pipe gallery structure.

Are Japan's water pipes a lifeline?

However, many of Japan’s pipelines have exceeded their 40-year legal lifespan, and the increasing frequency of earthquakes in recent years has made renewing pipelines and improving their seismic resistance a source of major concern for society. Water pipes are lifelines that are seldom seen by the general public.
