The Treasure Hunt of an Antique Dealer

26 30-ton carriages, don’t worry about where they came from. Zhang Nan and the guys are hunting for treasure, not studying the history of World War II. There is no need to go into these.

But now there is a big problem in front of everyone: Don't expect to open the exits on both sides of the tunnel. The only way to enter the tunnel is the ventilation shaft with a length of more than 100 meters.

According to Guan Xingquan's judgment, the 26 cars below should be fully loaded, and a small amount may be slightly overloaded. This is a big problem!

At least 750 tons or even more than 800 tons of materials need to be transported out of the tunnel through the ventilation shaft. If you rely on manpower...

Everyone is acting as a cow. If you kill 25 kilograms at a time, and 40 people take a ton, you need to climb...

More than 30,000 trips!

I don’t even bother to calculate the time it takes. It’s time for a trip, a few people crawling together, a group of people spinning around...

No matter how you turn it, it will be dead!

If you do it alone, even if you use yourself as a machine, you will have to move for several years at least!

Don't expect to rely on manpower, this will make Zhang Nan extremely upset at that **** slightly inclined ventilation shaft!

"If it's a vertical one, it won't be so troublesome. If you put a hoist on one side, you can directly lift things up.

Now it's too slanted to go up, and the steel steps on the bottom side can't use the hoist at all. You can't cut off all those steel bars, otherwise it will be troublesome to go up and down..."

Headache, very headache!

what to do?

Cold!

Let's eat first. In the winter, I will get a plate of sesame oil and salted radish to relieve the greasiness. I have notified the buddies who stayed in the hotel more than 200 meters away to deliver the meal. The garage door behind is all right. Except for the duty, everyone else gathers in the restaurant and thinks about it. Countermeasures.

It's basically a bad idea to think of everything, and after all deliberation!

Finally, there was a slightly more reliable one, which Zach came up with. The idea came from the failed moon landing mission of Apollo 13: It is said that after the spacecraft had a problem, the engineers on the ground experimented remotely to help the astronauts. With the tools and equipment that could be found, one big problem was solved one after another, and finally the three astronauts returned to Earth alive.

In a nutshell: professional matters are left to professional personnel, but those professionals cannot arrive at the scene to simulate solutions remotely.

Zhang Nan made a decision: "Just do it!"

The next group of people started to get busy after the meal, measuring the length, angle, diameter and internal specific dimensions of the ventilation shaft, the size of the steel handrail steps, and the approximate estimated strength...

Then they reported these data to the New York "Joint Force", which has its own engineering department, and gave it a copy. The data and requirements were also sent through New York to the copper mine in Chile, where there are experts in the practical and research of inclined conveyor machinery.

With just these few conditions, there is a supply of civil power, and power generation is also OK, you can design a simple and reliable transmission method according to the requirements!

A group of engineers, technicians, mine experts, and rescue representatives were reminded again of the confidentiality regulations and used their brains to invent in accordance with the requirements.

Confidentiality regulations are just prevention, because they don't know who requested it, what it was used for, or where to use it.

The research time is only 48 hours at most. After that, they are required to do model simulation tests quickly, and then if possible, find out the required kits that can be spliced ​​and transported, and then transport them to the designated location and hand them to the head office.

It is difficult to break the troublesome problem of Zhang Nan and others. After this was handed over to the professionals, it was not thought that the dinner time had passed on the German side, and the engineers on both sides gave similar solutions. It would not take 48 hours at all.

The power is still a winch, because the weight of the items that need to be lifted is not high, and it is guaranteed to be less than 300 kg, and the volume is not particularly large. Then use a single-sided slide and fix it on the side of the row of steel handrail steps in the ventilation shaft.

The difference in the design of the engineers on both sides is only in the height of the arc of the slide. In short, the design is half a catty to eight.

That’s it. It’s basically a happy result: in the end, the Chilean design won because they are a mine. The installation design of the prefabricated steel plates that constitute the slide is simpler than that of the American engineers, and the installation speed is faster and easier. The quality requirements of personnel are also lower.

After that, the Chilean guys started to get busy in the hardware processing factory of the Mining Group, manufacturing all the kits, keeping the quality and quantity fast, and when they were finished, there would be a freighter to pick up the goods.

People don’t use it anymore, just bring the kit, installation equipment and drawings together.

When the stuff arrives, that's the job of a bunch of bodyguards who have some construction experience.

Thanks to the high labor costs of the American society, these guys from the United States basically have strong hands-on skills, such as building a rack, **** a screw, and being able to use electric hammers and electric welding.

No way, some manual work is too expensive if you hire people to do it: Not to mention the poor in American society, many middle-class families have this craft, and repairs are done by themselves. High school courses even offer technical manuals such as car repairs. class.

As for the folks from Huaxia, there are not no builders and repairers who have been guest appearances. They use wrenches and hammers more often, and everyone has the basic ability to repair cars.

Mark has worked as a construction worker, and there are several people who have similar experience to him~www.readwn.com~ It is difficult to build the slide, but it is not difficult for everyone.

...

It takes time to build the slide kit, and even the measurement data takes time. Zhang Nan will not care about these details. After the meal, he went into the tunnel with Xiang Weirong and Guan Xingquan, plus Liu Wendong and Paul to check the goods on the train.

Paul and Liu Wendong first went to check whether there were any particularly large-sized goods in each carriage: it looked good on the whole, except for a few paintings that appeared to be large-sized, there were no other, at least no sculptures weighing a ton.

I just looked at it casually, and didn't even open the packaging, because Zhang Nan said: "If the size is too large, just leave it here for now, and seal the upper entrance again. This thing can't run away."

Zhang Nan, together with Xiang Weirong and Guan Xingquan, went to the westernmost carriage. The push-pull door was opened like this after being pried open. The rails underneath were all rusted and it was troublesome to push it out.

The carriage has a wooden floor, not much decay, and it's fairly solid. There are layers of boxes of various colors, large and small, at least a few hundred large.

Boss Guan put a battery light in the car door, and jumped up as soon as he put his hand on it.

There is no platform here, it is more than one meter high, and I have no skill.

Xiang Weirong was the same, grabbing the door of the carriage with his hand, and his actions were comparable to those of the buddies in the railway guerrillas.

Zhang Nan didn't have the skills of the two of them, and it took a little effort to get into the carriage.

Guan Xingquan lifted the light up and placed it on top of the row of crates opposite the car door, so that he could see more clearly.

"The ones on the west side seem to be all gold bricks, and the boxes on the east side that we pried open in front are all gold coins.

Most of the boxes are packaged by banks and should be classified, but one box was found when the goods were shipped out of the factory, that is, the goddess on the cloud. "
