440. Chapter 440
Tang Ning sat back and enjoyed the foundation laid down by his vice chairman Chenglin, and a Yangtze River empire was being built. Nanjing became a manufacturing center for windsurfing vehicles, Wuhan became another manufacturing center for communication equipment (the new communication pen), and Chongqing became a manufacturing center for flying houses.
At this point, the Yangtze River had truly become a sharp blade that cut the north and south of the Qing Dynasty, and most of the central government orders were ignored by the local authorities north of the Yangtze River. The central government itself moved from Changsha to Guiyang, a province with rugged mountain roads that was difficult to defend.
In order to connect the traffic on both sides of the Yangtze River, Tangning is planning to quickly build a large number of bridges across the Yangtze River. The key to building bridges quickly is the use of innovative pontoon technology. Whereas traditional bridge-building methods consume the vast majority of materials to support the enormous weight of the bridge deck, buoyancy technology will subvert this critical issue.
Suspension is not the same as soft clicking, it will use a steel mesh structure. Steel is a very strong metal, and the steel cable formed by winding multiple thin steels is both strong and elastic, which can be used as a support for steel cable bridges. The steel mesh used by Downing goes one step further, not only is it more powerful than steel cables, but it can also be used directly as a road surface.
In terms of design concept, the three-dimensional steel mesh is connected by complex intertwining, the bottom layer is sparse, and the higher it goes, the denser it becomes, and when it reaches the road surface, the steel mesh becomes a "cloth" woven of steel fibers, which is enough to support all traffic nodes, including humans, cars, and trains.
Because it is a permeable and wind-permeable mesh, the flood control and windproof ability of the bridge is superb, and the stability is also superb. The steel mesh itself is already very lightweight, but it can't hold up thousands of meters of steel mesh itself to accumulate huge weight, so the bridge body has to reserve a large number of cavities to accommodate the rubber airbags that produce buoyancy.
The pontoon bridge needs to cope with the navigation of ships like traditional bridges, so the design arranges a 160-meter-wide "gap" in the center of the bridge, at which the bridge is drilled below the water surface to allow traffic to circulate guò with an air-closed passage, because this will produce a lot of buoyancy, so it is more cost-effective than a bridge arch.
There is also something at the top of this opening, but it is only for the sake of balancing the underwater structure, not for passage, and it looks like a rugby ball in design. In order to remind the boat, a large number of light beads hang in the unseaworthy area, which absorb sunlight during the day and can shine overnight, as gorgeous as a pearl curtain.
During construction, such unseaworthiness warning lights began to be hung, and the first place of construction had to be the middle channel. Weaving such a mesh is an extremely complex process, but all the intricacies are masked by an automatic "loom".
The entire kilometre of construction began with four steel cables holding the river with fixed Optimus Prime at each end, and the kilometre bridge was all expected to be fixed by these two giant pillars. The size of the four skeleton steel cables determines the size of the entire bridge. Friends who have played with three-dimensional animal skin weaving machine will find that they are very similar when they look closely at the steel mesh woven by the wire rope weaving machine, and their basic raw materials are actually one small steel cable ring after another.
But in order to ensure the stability of the bridge body, the safety of the ring ring is strengthened by countless welding joints, almost every hundred steel cable rings have a welding joint, fortunately, the speed of spot welding only takes a few tenths of a second, and all are machine qì automatic processing, otherwise this work is too complicated, this whole project is afraid that there will be hundreds of millions of welding joints.
The Super Wire Mesh Braider is able to weave 100 meters of web 24 hours a day, and these nets are stuffed into an airbag that can be immediately passed through the truck, and a large amount of raw material (steel rope loops) is continuously transported to the braiding machine. Taking the Nanjing Yangtze River Bridge as an example, it takes only 16 days to reach about 1,600 meters.
If you don't count the gap in the middle, it only takes 16 days to build a permanent pontoon bridge. It's crazy, and Brunel, the master of bridge building, is afraid to vomit three liters of blood when he sees Windsor's speed. In fact, the gap didn't stop the crazy demon project for much time, because the hard structure could support the two ends of the gap and continue the construction.
Not to mention above the water surface, below the water surface can also be welded, yes, the special underwater welding machine is not afraid of difficulties, but the speed is slowed down to 24 hours 30 meters, 160 meters of underwater construction only took 5 or 6 days.
After the underwater net is finished, the airtight components are plugged into it, and the water is drained with a high-power pumping machine, and the whole shocking bridge building project will be completed from zero to 100% in about 20 days. Major media have reported on the project's prediction of the progress of the project by Windsor's road and bridge company, and it is the Nanjing Yangtze River Bridge (pilot), if it is changed to any other manufacturer, it is estimated that everyone thinks they are joking on April Fool's Day.
Of course, as long as they see the word "pontoon", they probably know why the project can progress so quickly, but what they can't understand is the word "permanent pontoon". The truth will not be revealed until the day when the work actually starts. It was only the first day that everyone discovered the mystery on the day of the start of work.
It turned out that Boss Tang used the knitting-like technology to build the bridge, which was unimaginable, until everyone saw the weaving machine QÌ moving along the four steel cables, and the paved pontoon bridge was actually able to pass the trucks. Engineering enthusiasts stepped forward to overlook the beautiful solder joints between the steel cable rings, and were shocked by the automatic spot welding machine and moved by the number of solder joints.
As soon as this technique came out, almost all the world's large-scale bridge contracts could not be signed, because it is said that the bridges built by this new technology can be dozens of times cheaper, and what fool government would dare to make a mistake at this juncture? The budget of this kind of super project is very terrifying, half of it is cheaper and it can kill people, let alone dozens of times?
In the past, before the advent of container technology, sailors went ashore for a day or even a few days, and when the container matured, the sailors' disembarkation time became half an hour, and there was no time to have fun. The appearance of the steel mesh bridge is also the same reason, originally had to stay on the construction site for several years, or even more than ten years, but it turned out to be 20 days, and the butt was not hot to set off again, such a project is almost like a pancake.
It seems that the flying house is really a must-have for bridge engineers at home, because the project duration has become calculated in days. And a large river basin only needs to have a construction team. After the Nanjing Bridge, the construction team can go back to the river, build a bridge in each city, and then sit and wait for the charge, this investment is really cost-effective, according to the old rules, such a profitable business Tang boss will not let others.
According to data, there are 176 rivers in the world with more than 1,000 kilometers, including 23 in China. Therefore, Boss Tang may build 176 super bridge construction teams and travel to various rivers around the world to solicit business. As for the small rivers, we'll have to wait until they're almost all right.
On average, 10 bridges were built on each of the 176 major rivers, that is, 1,760 bridges, and each bridge received 100 euros per day, and after the completion of the initial bridge business, the Windsor consortium could collect 176,000 euros, which is 64.2 million euros a year, enough to feed 6 million people. It's a real sense of accomplishment to think about.
What's even more rewarding is that these bridge construction teams are able to feed an additional 6 million people every year, which is even more impressive.
After the bridge was built, it had to be maintained, and the Nanjing Yangtze River Bridge became the first bridge in the world to be outrageously clean, because it was an all-steel structure that could be cleaned using lasers. Its principle is to use a laser to directly burn the dirt cemented on the steel cable into very small particles, disappear into the air, and there is no residue left.
Because the steel cable itself is heat-resistant and has a threshold, the laser will not cause damage to the bridge body. The laser cleaning truck drove over the bridge, and the whole bridge was as brand new as if it had just hatched from an egg.
Generally speaking, the cleaning truck chooses to work at night, but even in broad daylight, as long as the distance between passers-by and vehicles is calculated with radar, and the laser can be put away before the obstacle arrives. This technology is a must, as there are no pedestrians and vehicles at night.
This is the cleanliness of the road surface. There is also a version of the laser cleaning vehicle under the bridge, which cleans all the steel cables inside, which can be done once in a long time, but it doesn't take much effort. This unknown mystery will be pleasantly discovered by passers-by over time, as they will finally realize that the bridge is always freshly baked.
It's "burned" once a day, isn't it really just baked?
The military intelligence of the United Nations shows that the Entente has discovered the secret of the laser, so Boss Tang no longer needs to hide it, and the people who sent the laser team clearly explained the principle of the laser in the journal "Nature", and announced that the laser civilian project, one of which is to clean.
The most terrible dirt in the home may be the grease on the range hood, as long as it is metal, it can be cleaned with a laser, without water or chemical detergents, and you will be given a brand new machine within a few minutes. Boss Tang opened a "Phoenix Housekeeping Company" to show the power of laser cleaning technology with the meaning of Phoenix bathing in fire.
The company recruits employees in major cities around the world to use small laser cleaning machines to deal with dirt on metal products, not only metal, but also many hard and heat-resistant materials, such as marble floors, plain porcelain, etc.
The reason why Boss Tang set up a housekeeping company in a small way is that in addition to letting them be in charge of the bridge, it is also very useful.
There are so many canteens under the Windsor Enterprise, sanitation has always been a problem, and hospitals, the germs hidden in the dirt have always been a problem, and Downing has to metallize and ceramic all the public equipment so that it can be easily cleaned, maintained and disinfected.
The business volume in your own business alone is quite large, so Phoenix Housekeeping is completely necessary. It turns out that the chemical dirt in the factory is more difficult to deal with, and after hearing Phoenix's technology, the shrewd entrepreneur immediately found an excellent solution for his factory.
Rubber on steel, removal of stains on stainless steel surfaces, removal of car paint...... The torrent of steel in the factory has a large amount of business waiting for Boss Tang to send money every minute
