Chapter 184： Difficult and simple job

Laying railroad tracks is actually not that simple.

The entire laying work consists of the assembly, transportation and laying of rails, as well as the transportation and laying of ballast.

The first is the rail assembly.

The base for assembling the rails should be located as close as possible to the starting point of the rail laying station.

When there are two or more track points, several bases can be set up at the same time to carry out multiple track laying.

The track laying base is mainly composed of rail assembly line, rail material storage area and unloading line, rail storage area and loading line, locomotive running line, and working tools and equipment related to the above parts.

The so-called rail row is also called "rail section" and "rail frame". In fact, two rails are connected with a certain number of sleepers and fasteners to form a whole structure. Therefore, the first part of laying the rails is actually the rail assembly. It is like putting together a single arm in order to put together a piece of rail.

The second step is rail platoon transportation.

During the laying process, the rail bundle must be gradually moved from the rail transport train to the rail laying machine to continuously supply the rail laying machine. To meet this need, a special flat car equipped with rollers must be used.

When the new railway line is very long, the distance between the rail rows is very long. In order to save roller flat cars, this special flat car can be used only within a certain distance close to the front of the track laying, and ordinary flat cars are used in most of the journeys.

The difficulty of this step is actually not small. After all, the assembled rail is a very heavy guy. Because of its weight and volume, and the completeness of the most basic form, the transportation process is destined to be not simple.

The third step is to lay the rails.

The rail row is heavy and must be hoisted and laid by a rail laying machine.

There are many types of rail-laying machines, but the operations are similar. The new rail-laying line uses the lifting and transfer device of this type of machinery to lift the rail row from the rail-row car behind the rail-laying machine, move it under the front cantilever, and drop it into place. , Connected to the already laid rail row. Each time one track row is laid, the track laying machine moves forward one distance, and so on in a cycle.

The United States, Britain and other countries often use wooden sleepers and light rail rails when laying new lines, and then replace them with reinforced concrete sleepers and heavy rails.

Track-laying trains are used in the paving project, which continuously completes operations from demolition and collection of old rails to replacement of new rails.

In a small number of new line track laying projects or existing line track changing projects, gantry rail laying machines can also be used. It is a simple device that combines gantry and flatbed vehicles to work together. The gantry travels on the light small track temporarily laid on the shoulder of the road, and is used to lay the rail row loaded on the flatbed truck. Every time a section is laid, the small track is moved forward by manpower for a certain distance, alternately moving forward.

This laying method is simple in equipment and convenient to use, but the efficiency is low.

And this is still in the case of professional equipment. Like earlier, when there was no professional equipment, laying the railroad tracks is actually taking the people to pile up. I don’t know how many times similar things have happened in the history of the earth. Just check it online. That's a whole lot.

Then the fourth step is to lay the ballast.

The rails should be laid on the pre-paved and tamped track bed, but due to the large amount of ballast required for each kilometer of the railway, the railway itself must be used for transportation, which can reduce the freight and shorten the construction period. Therefore, other means of transportation are generally used first, and only a small number of ground floors are laid. After the tracks are laid, the trains are used to fill up the ballast as soon as possible.

The paving work includes many operations such as transporting, unloading, placing, starting, shifting, tamping, and ballast bed shaping.

Among them, the transportation and unloading of ballast are mostly carried out by special automatic ballast unloading vehicles. For the rest of the work, most of the construction is carried out with a ballast machine with comprehensive work performance.

In short, railway laying is definitely not a simple matter. In fact, Ankai watched a similar video shortly before the crossing, but what was recorded in it should be updated equipment.

It was a huge piece of equipment that looked like a big worm, wider than the entire railway line, with wheels on both sides and various equipment in the middle.

In the process of slowly moving forward, among those small equipment, the tool used to compact the ballast at the front is like a hammer with a handle. Wherever it passes, it keeps falling down, removing the original loose ballast. Strictly pressed.

Interruption is the equipment for transporting and visiting sleepers. It can transport a large number of reinforced concrete sleepers at one time, and then while walking, there is a robot to continuously lower the sleepers. Because the entire car is moving at a uniform speed, the sleepers are also placed very evenly.

Then there is the part where the rails are loaded. The ballast and sleepers in the front are all arranged, and the third part is the rails.

And as soon as the rails were put down, a small manipulator immediately put down the fillers in the middle of the two rails. This thing looks like plastic, but it's actually a new type of material. Its purpose is to cushion the squeezing between the two rails.

After that, it is the equipment that installs various components.

Such as spikes, rail supports, fasteners, etc., are installed in place one by one.

Of course, it is not realistic to complete such a complicated job at one time, but with such a machine, with a certain amount of manual labor, it is not too simple to install the rails.

An Kai just thought about it and got a hot heart. If he had a tool, wouldn’t he not have to work on his own, just let the other members of the shelter operate it directly?

But unfortunately, the system does not provide this kind of thing, so in the final analysis, he still has to do it himself Fortunately, the convenience of the system is that if he uses the system to build a railway, he does not need it. All sections of rails and all other parts are made, and then they are installed. This method is the best method that humans can think of, but it is too stupid for the system.

It's like the process of building various rooms.

He only needs to put the model out, put it there, and then carry enough material on his body, and the material can be automatically filled into the model.

As long as the material is enough, the model can be filled directly to create what he wants.

An Kai first laid a fifty-meter-long railroad track on the platform of the shelter.

Then he called out the model of the rail conveyor, placed it on the completed rail, and filled it with a batch of materials, and the machine was completed.

Because he was right in front of the shelter, he could teleport all the materials he wanted, so a large number of iron ingots, wood, and various other materials appeared from mid-air and landed on the transport plane.

An Kai himself came to the front of the transport plane, started the generator and engine, and then the rail transport plane began to move forward slowly. He has been controlling the trolley, and when he reached the end of the railway, he immediately stopped, called up a new track model, adsorbed it on the existing track, and continued to fill in materials to create a new section of track.

This method is really very convenient. Ankai quickly pushed the orbit five kilometers away in one day.
