After lunch there is a short break.
Although the season has entered spring, the temperature in early spring is still not high.
Cao Tou took two young people from his team to Yi Chuan in the residential area of the construction site.
After giving the number plate of his team in a familiar manner, the staff of Eizhuan took the three of them to a storage rack.
"It's all here. There's a cart next to it. Remember to return it when you're done."
The staff of Yi Chuan said a few words briefly, and then greeted the new people.
After following the construction site for such a long time, he also knew that the middle of every month was the busiest time for their construction site.
The volume of correspondence during this period is several times higher than usual.
The letters sent by post at their construction site are no different than other places. Most of them are large items, among which clothing, bedding and other items are the most common.
These workers send most of their annual wages back to their families. Together with the grain and cloth used as wages, the family's life is fully guaranteed.
With the cloth available, the women in their families would cut the cloth into clothing and bedding, and then send it back to the construction site via regional evangelism.
Although these things are important, they are actually not worth mentioning to many people in high positions.
However, for these people who spend three-quarters of the year eating outside, this is enough motivation to continue to support their efforts.
Therefore, to a certain extent, the importance of mailing by family members at the construction site is second only to military supplies in the e-mail system.
Cao Tou and the other three moved all the things sent by their team outside and loaded them on the wheelbarrow.
Outside the door, Cao Tou gave the two a few words and then turned back to the Post Office and filled in the information one by one for the things the workers wanted to send back.
The supervisors in Liaodi are not like the supervisors in previous dynasties. In addition to supervising the work of the workers, they actually serve more as safety officers.
They have been trained for a long time, and although their educational level is not as good as that of students who have truly graduated from universities, they have no problem reading and writing one to two hundred commonly used words.
They helped read and write many of the written letters home that the workers at the construction site received. When the workers had needs, they provided what they needed. Over time, the bond between them became very strong.
In the afternoon, there was joyful laughter everywhere at the construction site.
Here I heard from the letter that someone had a son in his family, and there I received the joy of having a son at home getting married.
In the past, people had to be organized to start work a few hours after lunch.
But every time in the middle of a month like this, the start of construction is delayed by an hour as usual.
2 p.m.
Workers at the construction site at the front of the road leveled the land again and laid two wooden rails on one side of the road.
They didn't know what the wooden track was used for. In the past six months or almost a year, the wooden track had been laid all the way from where they started to here.
But by about four o'clock in the afternoon, they knew the true purpose of these wooden rails.
I saw a huge monster emitting white smoke and making a roaring sound, slowly approaching from the direction of Taiyuan City.
The workers were frightened by what they had never seen before.
Fortunately, their foremen were all there and calmed down the situation with a few words.
The thing coming with the white smoke is naturally a steam train.
However, compared to the trains used on the rails, the trains running on the wooden tracks are one size smaller than the trains used on the rails.
The train did not go to the end of the wooden track, but stopped steadily a hundred meters away from the end of the wooden track.
Then, several carriages behind the front of the car were pulled apart.
Three to four hundred staff members wearing uniforms lined up and jumped off the train.
The supervisor of the road project team had been waiting for him for a long time. When he saw the person coming down, he greeted him with a smile and said it was hard work.
"Hahaha, thank you for your hard work. When you arrive, I know that the last step of this journey is about to begin."
"If there is more, we won't talk about it, let's start work, start work!"
The leader of the hundreds of newly arrived people also had the same smiling face as the road team supervisor. After a few words of greeting, he began to arrange manpower and prepare to start work.
These people are the latest batch of trained technical workers, and their main purpose is to complete the last step of the road.
Laying the asphalt mixture.
Yes.
Nearly ten years later, after taking over Shanxi, Zhang Qi got the asphalt mixture out of the road project.
In fact, asphalt mixtures have been available for a long time, but the previous focus was on occupying land, and there was no suitable time for actual road construction.
And now, the time has finally arrived.
The straight road from Taiyuan to Yanmen will also be the first real high-speed road in this era.
The reason why the first asphalt road was laid here in Taiyuan.
It was decided precisely because of the abundant coal resources here.
Asphalt can be roughly divided into three types, one is natural asphalt that exists naturally underground or in the open air, and the other is petroleum asphalt, a by-product of gasoline, diesel asphalt, etc. obtained through the process of distilling petroleum, also called petroleum asphalt.
The third type is a by-product of coking coal produced by distilling coal and wood, also called coking coal pitch.
The development of oil in Liaoning Province started early, but the output is currently not large. The oil deposits in the Far East are only a few open-pit mines discovered.
But in Taiyuan.
Because a large amount of steel was needed, a large number of coking coal plants were built early.
And the amount of tar-to-asphalt material obtained is almost too much to put down.
Therefore, for the future petroleum industry, Zhang Qi established a new technology based on tar distillation.
In principle, tar can do some of the things that oil can do.
It can also be used to produce gasoline and diesel, but the process is more complicated than petroleum refining.
But the essence is the same, that is distillation.
The disadvantage of coking coal pitch is that it mainly contains harmful substances such as anthracene, phenanthrene, and pyrene that are difficult to volatilize.
Although these harmful substances can be completely volatilized by heating in a high temperature environment of 260 degrees for five hours, the process of obtaining coking coal pitch does not require enough time even though the temperature far exceeds 260 degrees.
Therefore, the crude coking coal asphalt requires additional processing after it is released. The protection level of workers in the coking coal asphalt production plant is also the highest level in the entire Liaoning area.
With asphalt, Taiyuan also completed the asphalt mixture technology of mixing asphalt with sand and gravel under the guidance of the Liaodi Steering Group.
I can't say how good Liao's other technologies are, but in terms of fire refining technology, it can be said to be thousands of years ahead of this era.
The mixing furnace was removed from the train by workers.
The roller steel wheels of the road roller were also connected in front of the reserved space of the steam train with the combined efforts of hundreds of people.
Why lay wooden tracks?
For, it is the source of power to press the road.
Steam locomotive brand steamroller!
