The people of the Han Dynasty always loved their work, just as a child loved his delicate toys, and they were able to turn their momentary interests into motivation without any other thoughts, and they did their work as if they were doing something pleasant. Pen, fun, pavilion www. biquge。 info

If there is a big project, then the people of the Han Dynasty will definitely complete the task conscientiously, without mixing a little impurity, this is a virtue handed down from ancient times, after years of inheritance but still undiminished, still flickering in the hearts of every Han people, turning into a rippling blue wave, like a spirit, eternal and immortal.

Asphalt roads, also known as asphalt roads, are actually the same thing, but the names are different. Good asphalt is very expensive, there was no such thing as asphalt before the Han Dynasty, they were extracted from oil, and then after a series of chemical oxidation, they became asphalt for paving.

Originally, Sun Qi planned to lay a cement road on this journey, but facts proved that the quality of the cement road is extremely poor, and the cement road, that is, the concrete road, has very bad expansion performance, so it is planned to be cut into pieces and pieces, and its gaps will cause the bumps of the steam locomotive, which makes the cement road not the main road for transportation, and the asphalt road is different.

"This asphalt road, and the cement road base structure is almost the same, because the surface layer is relatively soft, the car is very comfortable to walk on it, and it is elastic, unlike the reinforced concrete used to build the house, which is too hard, the steam locomotive can not accept the uncomfortable road, otherwise it will not be happy to contribute his strength.

Again, although the asphalt road is defective, it is only hard, its black background, to walk on it people a sense of steadfastness, cement road background color gray, giving people a sense of vanity and lack of confidence, no natural feeling, the most important thing to drive and walk is to be practical, so the asphalt road can take advantage of this asphalt road in this regard.

But the other thing is that asphalt roads are suitable for this kind of transport roads, while concrete roads are suitable for pedestrian roads.

Although asphalt also has many disadvantages, such as dark light absorption and heat absorption, the pavement is easy to produce a range of dissolution after being exposed to sunlight, and the chemical composition of asphalt is unstable and easy to age. But that's all for later.

"If any group runs out of asphalt, be sure to notify the apparatus department to replenish quickly, at this point, everyone must remember that after paving a layer of pavement, do not step on it with your feet, otherwise it will destroy the integrity of the road surface."

Sun Qi divided the 300 young men into 30 groups, each team had a member of the equipment department to lead the workers, and each group was responsible for their own area, dividing the three-kilometer-long dirt road into different sections, and each of them broke through to plan for the future.

One of the tasks of the group has been completed, Sun Qi stepped forward and stepped on it, and found that although this asphalt is darker, its hardness and toughness are stronger than in the previous life, which may be a pure natural public, additive-free material!

"It's not that I haven't thought about it, you have to know that the cement road is paved with a layer of asphalt, although this saves materials and saves workmanship, but it must be a tofu slag project that cuts corners, and we absolutely can't accept it."

Sun Qi put his hand on a young man's back, his face was a little stiff, and he pointed to a piece of road that was about to take shape and explained, he tried to explain why he didn't use cement, because after cement became popular in Jiangning, everyone loved this simple and rough building material, which was down-to-earth and made people feel real.

Sun Qi knew that these young people were all good young people, and they would definitely not be like those learned architects in their previous lives, who told big lies in their mouths, but what they did was something that villains were not as good as villains.

They work on the construction site, they are absolutely first-class and honest, they will never mix a trace of water into the asphalt, and they will never hide the limited asphalt and make the overall quality of the road deteriorate, they will always pay attention to professional ethics.

For example, in a city and county in the previous life, a layer of asphalt was paved on a layer of cement pavement, white to black, and then it was hard to say that this was an asphalt road, and as a result, a large number of overweight vehicles went back and forth on it, which led to the collapse and damage of the road surface in a few days, causing several casualties. In Sun Qi's eyes, cutting corners is the most humiliating thing, it is more hateful than the enemy's invasion, and more shameless than the political enemy stumbling up.

"Although we have to spend some maintenance money every year to repair the road, this is really the best road surface for steam locomotives, and if we use cement, the road will collapse in a few days."

Sun Qi carefully inspected several teams and patted them on the shoulder and explained carefully. Why not use cement; For the sake of paving.

The estimated total amount of the project is about 3,000 kilometers, and Sun Qi asked the equipment department to prepare more than 40,000 catties of asphalt in advance, which is a pre-preparation for the company, because the asphalt is extracted from crude oil, and it is impossible to take out so much at once.

"Report, the front is blocked by a mound of dirt."

Sun Qi was in a dirt mountain several feet high, no, in front of the mound, he contemplated with his eyebrows, this little student who reported to him was Sun Qi's close disciple Wu Qiuyue, he is now proficient in chemical knowledge, and he did all the hard work of purifying asphalt.

The road, which is about to be built, has been safeguarded, and the garrison department is on duty night and night just to complete it quickly.

Sun Qi thought about it carefully, trying to relax his thoughts, several words kept flashing in his mind, which made the sound of popping in his mind all the time, opening mountains and building roads, opening mountains and opening mountains, and meeting rocks and gravels.

"Go to the equipment department and ask for dozens of catties of black powder, and we will blow up this mountain for him."

Wu Qiuyue, who returned from school, became more and more calm, and did not drag her feet at all, so that people could not see that she was a daughter, in fact, after the imperial examination, Sun Qi and Wu Qiuyue had a lot less contact, Sun Qi presided over the work in the county government, and Wu Qiuyue devoted herself to studying and researching various studies in Wenzheng School, and now if Wu Qiuyue is allowed to participate in the college entrance examination in her previous life, she will be a champion in the county no matter what.

The black powder black block was brought, you must know that black powder and explosives are completely two different concepts, Sun Qi has not yet finished the manufacturing drawings of explosives at this time, and black powder is the best blasting tool that can be found.

Sun Qi ordered someone to find a huge jar, poured the dozens of catties of black powder into it, and then sealed the big jar, and led it out with a lead, leaving a lead similar to a detonator.
