Hebei in the Northern Song Dynasty, close to the Grand Canal, here is a flat river, at a glance, is a rich land, but not far away, but is a huge construction site, not only concentrated a large number of personnel, but also some very special tools, especially on the railway vehicles, which are specialized in road construction vehicles.

A new railway line is being built rapidly, and the professional and technical team of the Dinghai Navy and all kinds of machinery have landed in the Northern Song Dynasty.

They thought that they were the most elite, and in the past, they had built a lot of railways, maybe not as good as the Dinghai, but they would not be much worse, but after they really got in touch, they found that the difference was too far.

The current construction method of the Dinghai Navy is completely incomprehensible to them, which is completely different from what was taught before, but the efficiency is very high.

Following the Dingjun, studied for a few years, and later, in most of the railway projects in the Northern Song Dynasty, they were the main force, and also built a large number of railways.

That's right, not to mention the workers of the Northern Song Dynasty, even if it was from the Ding Navy, he built the railway two years ago, as long as he didn't touch it for two years, he really fell behind, because many processes are completely different.

That's right, in the Dinghai Navy, the development of industry and technology is so fast, especially in heavy infrastructure, with the emergence of various tools, especially heavy tools, the entire construction steps have undergone great changes, and if you don't continue to learn, I'm afraid you can't find the right steps.

Originally, the construction of the railway, mainly some tower cranes and hoist cranes, such individual manipulation of labor-saving devices, they played a huge role in the early stage of railway construction, a 12-meter-long steel rail, hundreds of kilograms, if there is no labor-saving tools, simply carry them, it is very difficult, although it is said that with a certain number of people, it can be moved, but because it is too heavy, power consumption, there will be deformation of action, so that the rail installation is not so good, or there is an accident, casualties, no matter which, which was not the original intention of building the railway.

There are hoist cranes and tower cranes, which can save effort and increase labor efficiency, but tower cranes are like this, and it is inconvenient to move, at most dozens of meters, they must be re-installed, but overall, the efficiency is higher.

With the advent of the steam engine, even if the output of the steam engine is a little low now, it is not enough to simply supply the railway, and the effect of such a steam engine on the railway is indeed very good.

After a little research, 10 trains with 40 steam engines and specialized in the construction of railways appeared in the sequence of the Dinghai Navy and became the key to road construction.

The huge horsepower brought by 4 steam engines has made countless railway construction, the projects that need to consume power have become relatively easy, and the railway line from Shanhaiguan to Bianliang, a total of more than 900 kilometers, 1800 miles, is divided into 10 bids here, each of which is only responsible for about 180 miles, so that the construction of multiple sections can greatly improve the efficiency of construction.

This kind of separation, in the past, was a little small, in the Northern Song Dynasty when the pursuit of efficiency, not to mention 180 li, 30 li can be divided into a bid section, a railway four or five hundred kilometers long, with more than 20 bids at the same time, so the efficiency is very high, maybe one or two months, can be built.

The use of steam locomotive railway, can not be so casual, when the speed is fast to a certain extent, on the rails, any negligence, will cause huge consequences, coupled with the safety brought by the speed, for the railway requirements are higher, it is impossible to be as laissez-faire as before, in the construction personnel provided by the Dinghai Navy, the proportion of skilled workers is quite high.

The emergence of 10 road construction machinery has solved a huge problem, from the strength, the most ordinary steam engine, which is at least equivalent to the power of hundreds of horses, converted into human manpower, it is more, in the traction, transportation, installation and many other projects, the steam engine has played a huge effect.

Not to mention, in the past, to install a rail, the use of hoist crane and tower crane under the premise, it also takes at least 30 minutes or more, if you count the time to install hoist crane and tower crane, it is more, that is, a large number of grouping, the entire construction team, divided into dozens of parts, for the construction of separately, on the unit area, more people, so as to ensure speed.

However, if the premise of using machinery, the installation speed of a rail, under the most extreme premise, can reach less than 5 minutes, and the laying of other aspects will also be faster with the help of machinery.

Machinery is always more efficient than manual work, especially in this way, machinery that can provide huge energy, as long as the overall combination and familiarity with the use of this machinery, can improve efficiency on a large scale.

This greatly accelerated the construction of the 1,800-kilometer-long railway, which was divided into 10 sections, even faster than they had once divided into 40 and 50 sections.

Now, most of the railways have been laid, and there are only a few bridges left, fortunately, here, there is no Yellow River bridge, the largest, that is, the river thirty or forty meters wide, these are not a problem for the Northern Song Dynasty, let alone the Dinghai.

From the start of construction in August to the beginning of October, it has been almost two months, but it is almost almost complete from completion.

For ordinary railways, for example, the railways of the Northern Song Dynasty have been quite slow, and the railways of the Northern Song Dynasty have been built much faster than this, but this railway is different, not to mention anything else, the quality of the bridge is several times higher than before, not only better cement and steel bars are used, but also a lot of amount is reserved to prevent problems, generally speaking, it takes almost half a year.

After the Northern Song Dynasty put forward a large number of imported workers, an order was issued from Shenyang to speed up the construction of the railway, and even four newly built road construction machines would be put into the construction of the railway from Shenyang.

With more personnel and more machinery, the speed of railway construction has suddenly increased greatly, especially the breakthrough of two key bridges, this speed is even faster, it is expected that at most half a month, this railway will be fully connected.

Han Jiang put down the secret letter he had just received, which was sent from Shenyang, directly aimed at the labor export of the Northern Song Dynasty, one was to reply to his question, that is, the entire 3 million management fee, agreed, first transfer the funds of the Tianlu Plan, if it is not enough, it will be directly supplemented by the Dinghai Navy.

Now the Pilgrim Road Project is actually in a state of stopping, no matter what, let's get these 3 million people right first, and then talk about it, with these young and strong, the people who will visit their relatives in the future will have a reason, and they can break it into pieces, and even pass through this road in a grand manner, instead of the hidden Celestial Road, which is also normal for the large-scale reduction of the investment in the Pilgrim Plan.

Of course, Han Jiang knows that this money is not a big problem at all for the Dingjun, for the sake of 3 million laborers, let alone 300 million, even if it is more, he is willing to pay it out.

3 million people, not tens of thousands of people before, this needs a complete capacity, the main force is of course the train, I don't know when the new railway line can be built, before that, he can only consider the railway from the Northern Song Dynasty to Shanhaiguan.

A train, 3 carriages, squeezed, can almost accommodate 120 people, that is to say, a train can almost accommodate about 360 people, 3 million people, and 10,000 trains.

Based on 40 trains a day, it would take 250 days to transport them all.

This is more than half a year, not to mention that the Northern Song Dynasty does not agree, even if it is a navy, it will not waste time, why did the Northern Song Dynasty agree to this method of three draws and one so quickly, isn't it just for money, in order to agree as quickly as possible, they even did not hesitate to give Dongfu 1 and a half, and at the same time accepted, and even deducted 4 into 5 in the first year, in order to pass in the fastest time, and then get enough management fees.

For more than half a year, or even almost a year, they are absolutely unwilling to wait, and everyone will know about the extraneous branches.

3 million people, is a very large number, must be taken seriously, before the Northern Song Dynasty did not realize it, get people to the Dinghai Navy, go, it is impossible for the Northern Song Dynasty, only this group of people get it, and then, all the work is easier by half.

The current transportation speed of the Northern Song Dynasty, although the railway still has spare capacity, but there is not much, increase the density of departures, this does not seem to work, the management of the Northern Song Dynasty, has reached the limit, no matter how fast, there will definitely be problems, when the time comes, let alone increase,

If it is increased, not only will it not be effective, but it will go wrong, and it is a big problem.

If there is a problem, it is not something you want to see, this is the person who is transporting, or the density is very large, and if you really die, it will have a big impact.

Fortunately, Han Jiang still thought of a solution, and after seriously inquiring about the railway density of the Dinghai Navy, he found that if the railway from Shanhaiguan to Bianliang was upgraded, there was no need to change the equipment or anything, and the personnel of the Dinghai Navy were directly used, which could increase the density of the entire exercise by three times, that is, the number of trains sent per day could reach 120, which was equivalent to saying that the efficiency of transportation had been increased by more than three times at once.

In this way, even if 3 million people are sent over, it will only take 2 months.

At the same time, Han Jiang is also more concerned about the messenger railway from Bianliang to Shanhaiguan, after the railway is repaired, not to mention the speed, the speed is only secondary, and the load of a train is enough to solve this problem.

A train can have 15 to 20 carriages, and a single train can take 2,000 people, and if you send 50 trains a day, it will be 100,000 people.

After communicating with the Northern Song Dynasty, Han Qi keenly agreed and agreed to the requirements of the Ding Navy, and on the railway line from Bianliang to Shanhaiguan, the management personnel of the Ding Navy were introduced to improve efficiency.

Everything related to immigrants is all in the first order, and even the navy has directly prepared personnel, and once the Northern Song Dynasty agrees, after the news is transmitted back, it will immediately enter the territory of the Northern Song Dynasty and take over the entire railway.

At the same time, all the data on the railway have been recorded, and through the huge computing power in the rear, the calculation has been completed, and some preliminary adjustments have begun.

On the first day, nearly 50 trips were adjusted, which not only increased the overall efficiency by more than 10%, but also increased the number of vehicles by about 20%.

This alone has increased the efficiency of the railway by more than 30%, which means that even if the railway is used, it can save nearly 2 months.

However, the follow-up changes are still continuing, one by one, one by one, the calculation of the data combined with the overall control, not only each train, they maintain a relatively stable speed, but the overall efficiency, the provision of vehicles has also increased rapidly, every day on this railway line of vehicles, also began to increase, soon to the previous 2 times, after the growth rate gradually slowed down.

The improvement is very significant, but for the Northern Song Dynasty, it is confusing, these are the easiest steps, it seems that there are not many adjustments, and there is no eye-catching method, but on the whole, it is so high, what is the principle.

The principle of parallel and the principle of co-ordination, which was only proposed and studied in the 20th century in the later generations, was proposed in the era of the Northern Song Dynasty, of course, the Northern Song Dynasty did not understand, just like the simplest co-ordination, it takes 10 minutes to boil water, 8 minutes to wash dishes, and 2 minutes to make tea, which is an addition for the Northern Song Dynasty, but in the overall planning, some can be prepared in the middle of the time, can be combined together, it forms a saving, do not understand the whole basic principle, of course, see a simple adjustment, The end result is a magical effect.

The Northern Song Dynasty can not learn the principle, but it will be better than the gourd, if the implementation of the entire rules and regulations is strictly followed, it can improve efficiency, but there is no fine-tuning, in the long run, many things will change, slowly, the quantitative change to the extent of qualitative change will become slower than before, even to the extent of disorder.

When the time comes, if it is forcibly implemented in accordance with the rules of the navy, not only will it not produce too many effects, but it will be a mutual influence, and it will even be less scattered than before.

These Northern Song Dynasty didn't know, but the Dinghai Navy knew that these personnel of the Dinghai Navy were responsible for sorting out the route of the entire railway, and made simple adjustments from the layout to the time and speed of the trains, and the overall efficiency was significantly improved, and with the increase in familiarity, the efficiency of the improvement became faster and faster, and the personnel transported every day became higher and higher.
