Zhang Tao did not drill holes in the center of the island directly, but drilled on one side of the island model to avoid the collapse of the load-bearing body of the island.

A passage is designed in the space of the island, and on both sides are large rooms for machine tools and other equipment, and a floor of rooms is designed above for placing materials. Slide the mouse to cut off a piece of the hole at the end of the hole on the first floor, and then extend it forward for a distance so that the high tide at sea level is halfway through the passage.

A right-angled passage was drilled upwards at the end of the passage, and then a horizontal passage and some large rooms were drilled out to smelt materials such as metal, which were transported to the machine room through a passage with seawater.

The passages and rooms of the island are designed to allow some space for the installation of sound-dampening materials, etc., and the processing machinery inside the island will transmit the sound to the seawater, which is not good for the submarines of some countries to hear.

After designing the base of the island, Zhang Tao used a machine tool to process some large ultrasonic machines, which were specially used to drill holes in the island and expand the room. Then the purchased forklift was disassembled, turned into parts, and then cut the plastic sheeting to package the parts one by one, and then measured the size, bought some cardboard boxes of the corresponding size on the website, and packed the parts wrapped in plastic sheeting with cardboard boxes. 【△Net】

Zhang Tao remotely controlled the submarine in the waters near Iceland to drive to the dock of the seaside villa, and when it was dark at night, he found a few bundles of black sunscreen cloth in the material room of the factory and covered the pier with a layer above the pier to prevent satellite shooting, and put the packaged parts into the submarine.

After returning to the training ground, he turned on the computer, and the remote control of the submarine robot was plugged into the chassis with a data cable, and the mouse operated the submarine to drive to the small island in the Arctic Ocean.

On the way to the island, he found that the sonar equipment had submarines, boats or seaplanes, and then he lowered his speed, and after more than half a day, he arrived at the position where the bottom of the island was to be drilled, and released several small submarines, one floated on the surface of the sea and used communication to convert contact, and the other were next to the submarine, and the remote control robot pushed out a large ultrasonic device from the bottom of the submarine, and then remotely controlled several small submarines to install the large ultrasonic wave in front of the submarine.

Zhang Tao remotely controlled the submarine robot to operate the submarine to the bottom stone wall of the island, and then turned on the frequency of the ultrasonic stones, and after a few seconds, the stones on the stone wall turned into powder and fell into the sea with the lapping of the tide.

The sonicator is packaged with waterproof plastic sheeting, but the ultrasonic waves only work on objects of the same frequency and do not damage the waterproof plastic sheeting. After a while, the passage became longer, and the stone powder mixed with seawater turned into mud and piled up in the hole, and Zhang Tao remotely controlled the robot to turn on the compressed air.

After seeing that the air pressure on the equipment instrument was stronger than the pressure of the surrounding seawater, he took out the grappling bucket of a forklift from the cardboard box, and the waterproof plastic sheet was also not removed, and pushed it into the sea from the bottom of the submarine.

Zhang Tao remotely controlled a small submarine next to him to catch the bucket and then installed it on another small submarine, and remotely controlled the small submarine to push the dirt out of the passage. The hole in the stone wall is drilled with ultrasound, and the sonar is not very safe, and when the soil is pushed out, it is slowly pushed and the sound is not loud, and the speed is reduced to a minimum near the hole entrance.

The passage is arc-shaped, and it turns a few times in the rock to drill to the predetermined position, and then remotely controls the small submarine to turn ninety degrees to open another channel, and after the four arc-shaped passages are drilled, Zhang Tao remotely controls the submarine to release a small submarine in the sea near the island to find a submarine cave and hide it, and collapses the hole.

Now the hole drilled is very long, the stone wall in the cave has not been reinforced, it is not very suitable for the submarine to stay for a long time, after a day Zhang Tao has dinner and remotely controls the submarine out of the submarine cave, remotely controls the small submarine back into the submarine, and drives to the island at a depth of 30 under the sea surface.

After reaching the sea above the hole in the island, two small submarines were released and used on the surface of the sea as a communication link between the submarine and the surface. The images sent back by the submarine show that the walls in the passages are very flat and smooth, and after reaching the center position, the intersection of several passages is enlarged according to the scheme simulated on the computer.

Then open up several passages, the passages are not all on the same level but different heights, some are like a deep well under the sea, some are like a cave leading to the land, very tortuous, when drilling the hole, the route is recorded with a camera and transmitted back to the villa's computer, Zhang Tao also used a book and pen to draw down the line as a backup.

After all the passages and rooms in the island were drilled, Zhang Tao remotely controlled the submarine to the stone wall near the entrance of the island and cut down four stone blocks and put them in the hole, and then used an ultrasonic instrument to open a space that could enlarge the stones at the passage position not far from the hole.

The stone is very thick, Zhang Tao has calculated that even the strength of a whale can not hit it, but every time the door is slived, it takes more diesel, and behind the stone sliding door, Zhang Tao plans to open a small passage to put the submarine in and out to refuel and overhaul the machine.

After putting the things in the submarine into the material room, remotely controlling the submarine to hide in a nearby submarine cave, Zhang Tao began to disassemble the machine tools, turn them into parts one by one, package them with waterproof plastic sheeting, and then measure the size of the parts and order some cartons of corresponding sizes on the Internet.

After the cardboard boxes were delivered, Zhang Tao opened the machine tool parts with the cardboard box board, and after all the machine tool parts were packed, he remotely controlled the submarine back to the dock, covered a black sunscreen cloth above the dock, and pulled the parts to the dock with a trailer and loaded into the submarine.

After driving the trailer back to the training ground, Zhang Tao went to the computer room and remotely controlled the submarine to drive towards the island. After arriving at the machine tool room on the island, let the submarine surface in the passage, release some industrial robots from the line, and then move the parts out, remove the cardboard box and put it back into the submarine.

After remotely controlling the submarine to transport materials to the island several times, Zhang Tao's expected materials and equipment basically met the requirements of the construction base, and now the stone sliding door near the entrance of the cave is done, and a steel rail slideway is made under the big stone, and then a steel plate with pulleys is embedded under the stone, and the steel plate and pulley are chrome-plated to prevent the corrosion of seawater.
