Zhang Tao checked the information on the Internet and in the library, but did not find out how to build a waterproof space on the seabed, it seems that the construction of a waterproof space on the seabed is a high-tech confidentiality. Pen % fun % Pavilion www.biquge.info

There is information on the construction of waterproof tunnels in the aquarium, but they are all built and then release seawater, Zhang Tao has not heard of any country building an underwater world in the real sea, and if he can't find the information, Zhang Tao took tools and machinery and drove to the beach to inspect it himself.

After arriving at a public beach, Zhang Tao parked his car in the parking lot, took off the umbrella from the car, plugged it in a sandy beach surrounded by plants, and then removed the folding table and chairs, as well as the equipment on the car, and put them under the umbrella.

Zhang Tao sat on a chair in a cotton jacket and looked at the sea, the waves on the sea level were wave after wave, but the sea water under the sea was calm. Looking at the sea for a while, Zhang Tao shifted his gaze to some green plants on the shore, and some moss grew on the reef.

Zhang Tao looked at the moss and thought of some plants on the bottom of the sea, seagrass, kelp, seaweed, and mangroves growing on the beach would not stop growing even if they were submerged by the sea at high tide.

It's a good idea to mimic the plants of the seabed, where the sand is more than a dozen meters deep, and the rocks below. The sand on the seabed is dug up with underwater equipment, and then the rock is smoothed, and then a hole is drilled in the rock, and the rubber and barnacle glue are transported underwater to glue a layer to the wall of the rock cave, and then a large stainless steel pipe is inserted into the hole, and then the seawater inside the stainless steel pipe is pumped out and blocked.

The stainless steel cylinder is designed to have three compartments that can be opened, the top layer can use tempered glass, the light in the sea shines into the hole, the robot and air compressor, liquid oxygen tank, liquid hydrogen tank and other equipment are wrapped with waterproof plastic cloth and pre-placed into the bottom of the stainless steel cylinder, and a pressure measuring instrument is placed in the middle cylinder.

On the outside, a waterproof pump is used to pump out the seawater inside the stainless steel cylinder, and there is no water in the space inside. When entering the stainless steel pipe, the remote control robot operates the equipment to produce oxygen, so that the pressure in the stainless steel cylinder in the middle is stronger than the pressure of seawater, and the seawater will not rush into the stainless steel cylinder when the tempered glass cover of the stainless steel pipe is opened.

After thinking about the construction of the seabed waterproof space, Zhang Tao stood up and moved for a while, and took the equipment to the beach. Zhang Tao used a thermometer to measure the temperature of the seawater, and the thermometer showed that the temperature of the seawater was eight degrees above zero.

Then use a needle to pump some seawater into a bottle and take it back to the table, pour some seawater into a beaker, and take some materials to make steel plates and other materials for the corrosion resistance of seawater, after all the tests, the seawater in the Arctic Ocean has no problem except that it is colder, and it is not very corrosive to steel plates and glass.

Zhang Tao packed up his things and loaded them into the car and returned to the farm, the submarine was not a problem for a few days underwater, and the women occasionally went to see the world under the lake. Zhang Tao purchased drilling equipment and several stainless steel tubing from Robert, as well as stainless steel plates and other materials.

Zhang Tao found out the infrasound waves of land animals stored in the computer, copied the frequency into the micron generator of blank infrasonic waves, and then installed micron-level infrasound devices in the remote control and the communication processors of submarines and several small submarines to receive infrasound waves, and used the code book to convert the infrasound waves of several animals into the operation program of the submarine, and then re-wrote the frequency of the communication processors that required several equipment, and changed the original up, down, left and right and other long waves to infrasound waves of land animals.

After the infrasonic device was installed, Zhang Tao put the small submarine on the water, then sat in front of the computer in the workshop, connected the remote control to the chassis with a data cable, and remotely controlled the operation of the submarine.

After the remote control test was completed, Zhang Tao took a submarine to the bottom of the lake to take pictures of the terrain, and then returned to the research room of the workshop to use computer software to simulate the terrain of the lake bottom into a dynamic pattern. The stainless steel pipes and drill bits are also simulated, and the sand is shoveled away at the bottom of the lake to install the stainless steel pipes.

After simulating on the computer, after considering the problems that will occur in the actual drilling, Zhang Tao transformed several small submarines and installed manipulators, then moved tools and materials to the submarine and sank to the bottom of the lake, and put a shovel on the manipulator of the small submarine and sent it to the lake through the entrance and exit cabin at the bottom of the submarine.

Then use the remote control to remotely control the small submarine to scoop up the sand at the bottom of the lake to be drilled and put it in the distance, scrape the rocks flat, and then operate at close range underwater without the use of a sonic wave. After the sand was dug up, the surrounding sand slowly flowed down, but there was not a lot of sand that fell from the water with buoyancy.

When the sand was almost finished, Zhang Tao transported the second small submarine with the drilling machine through the entry and exit cabins, and there were three steel bars covered with iron rings on the drilling machine, and the remote control of the small submarine used a manipulator to nail the three chisels to the underground rock, and then the iron ring on the pliers was straightened with steel bars to make the cylindrical surface of the drilling machine and the rock in horizontal contact, and the steel bars were tightened and wound around the iron ring several times and then a knot was twisted.

After inserting the drill bit into the drilling rig and locking it, press the waterproof button of the power supply of the drilling rig, and then adjust the running speed to medium speed, and the drill bit drills down slowly at a constant speed. After ten minutes, the drill bit drilled ten meters deep, and after pressing the drill bit exit button, the drill bit quickly rotated counterclockwise and returned to the top of the rock.

The small submarine was remotely controlled to send the drilling rig and drill bit back to the submarine in two parts, and at the same time, a small submarine was released to the drill hole with liquefied barnacle glue and rubber sheets, and the manipulator was operated to apply barnacle glue and rubber sheets to the cave walls.

After a few minutes, the rubber sheet was glued, and the remote control of the small submarine brought the remaining rubber sheet and barnacle tape back to the submarine, and then transported the welded stainless steel cylinder to the hole with the small submarine, there is a negative gap between the stainless steel cylinder and the rubber, so that the lake water can be squeezed out, and the stainless steel cylinder will be stronger.

The remote control robot connects the air compressor to the oxygen cylinder and the hydrogen cylinder, and puts oxygen in the middle cylinder. Since the gas in the oxygen cylinder and hydrogen cylinder is liquid, and it becomes a gaseous state when it is put outside, the liquid hydrogen and oxygen quickly increase the pressure in the middle cylinder of the stainless steel pipe to the same as the seawater outside, and the oxygen concentration is too high to explode, so it is necessary to add some other gases to mix.

Seeing that the pressure tester in the stainless steel cylinder in the middle showed that the pressure was stronger than the pressure of the surrounding seawater, after opening the tempered glass lid, not a drop of seawater entered the stainless steel cylinder, and the remote control of the small submarine stretched the manipulator out of the seawater into the air and took it out, and there was still no water in the stainless steel cylinder.
