By itself the robot is not a weapon or sensor.But in order to buil the infrastructure of underwater great wall you need the tool And that is exactly what this robot is for.So today news in big step in realization of underwater great wall

Here is the actual video


And here is the robot in work to lay cable and buried it under the sand

And here the future look like for underwater great wall

Underwater Great Wall of China

The Underwater Great Wall may be centered around stationary sensors on the ocean bed, but autonomous unmanned underwater vehicles will be a critical enabler in not just tracking enemy submarines, but finding them. Also note the large AUV's reflection on the display glass.

The Chinese Navy, the PLAN, appears to be following in the footsteps of its sister service, the People's Liberation Army Air Force, in making growing investments in unmanned surface and underwater systems, aka "drones." A new Chinese exhibit shows the scale of the potential future.

A Wide Range of UUVs

China is experimenting in building autonomous UUVs of all shapes and sizes, looking to make them work together with each other, and Chinese warships too.

One area where unmanned underwater vehicles (UUV) and unmanned surface vehicles (USV) would make a splash is in Chinese anti-submarine warfare (ASW) efforts. ASW capabilities have been a longstanding weak spot for the PLAN, leaving it at a disadvantage to American and Japanese attack submarines. As a response, the China State Shipbuilding Corporation (CSSC), which builds virtually all PLAN warships, has proposed an "Underwater Great Wall" of sensors, positioned on the seabed floor, to listen for enemy submarines. (The US had a similar system on the Atlantic Ocean floor to listen for Soviet submarines.) Such underwater listening posts may already have been installed near the giant PLAN base at Sanya, Hainan Island in the South China Sea. On a more optimistic note, CSSC suggested that an Underwater Great Wall would be useful for warning against natural disasters like tsunami, and could be used to collect research data on marine life and geology.

System of Systems

Future Chinese anti-submarine warfare systems will rely on a wide arsenal of autonomous and surface unmanned vehicles, in addition to acoustic (and other types of) sensors installed on the ocean floor.

In addition to active and passive sensors located up to 3,000 meters underwater, the Underwater Great Wall will be supported by a wide range of USVs. Chinese researchers intend that these autonomous USVs will be able to work in conjunction with the seabed sensor picket line, and autonomously locate and track enemy submarines.

Continuing research on these technologies can also help to develop a future base in either the moon and/or Mars.

When we see the top view of this islet we loose perspective how big this island is . Here are some striking photo from the ground courtesy of xinhui
Indeed it is immense just like real island

I wonder if they considered higher Sea levels from global warming?
Sea level is rising by less than a centimetre per year for the time being. Islands are being lost, BBC Radio 4 had last week a program in which someone visited the remains of the house he had lived in and that was now under water in the Solomon islands, but raising ground level when buildings are replaced or rebuilt should be enough.

The reason I mention this is because the islands looks to be only a couple Meyers above sea level. Most large builds like the hospitals would need foundations 5-6 Meters deep, not including basements.

Also over time there is usually settlement of several mm a year. Not significant but could a problem in the future.

Essentially if the water level is too high, it would be bad for the foundations, either concrete or steel piles.

You can design foundations to account for these circumstances. Many buildings in the Netherlands are standing, some already for centuries, on foundations of wooden piles and trouble has now come because the ground water level has been lowered artificially and the tops are now rotting away.
I expect the foundations on the new islands are of sea water proof concrete. The preceding constructions were first build on steel piles which no doubt had a limited life expectation and then larger structures that used concrete.
