Xie Mingfang's current location is the fourth phase of the railway project in the Oriental Port Transportation Development Project, and the line from the wharf to the bulk cargo warehouse west of the Oriental Port has been laid, and a track has been laid on this line and has been in operation since mid-1629. However, the track that is already in operation is a narrow gauge, or a very narrow track, and the train operating on such a track, whether it is the locomotive or the carriage, has the trouble of the locomotive being too heavy to affect the stability of the car body, so the vehicle has to maintain a speed of 20 kilometers per hour during the journey.

Although this speed is much faster and better than that of cart transportation or personnel shoulder-carrying, the veterans who have crossed over from the old world look at this kind of transportation prevention as if they have superpowers like Flash, but they have to walk slowly like ordinary people, which is almost unbearable. You must know that these steam engine locomotives were designed to meet the speed of 70 to 80 kilometers per hour, and there was even a design scheme for a speed of 100 kilometers per hour, but such fast trains had to run at a speed of 20 kilometers per hour, which was far from meeting the needs of internal transportation in the Oriental Port in terms of efficiency.

In this case, the transportation department proposed a double-track laying plan, while ensuring the existing capacity, lay a broad-gauge double-track, and wait for the double-track to be put into transportation, and then dismantle the previous narrow-gauge line and re-lay the broad-gauge route - as for the line, there is no need to re-plan, because the narrow-gauge is actually laid according to the data of the broad-gauge when laying, especially the turning angle and other problems have brought a lot of trouble to the narrow-gauge vehicles, which has to reduce the speed of operation. After the two broad gauges are laid at the same time, it can be transported on two tracks, which increases the efficiency geometrically.

The workers on the construction site are wearing thin overalls and are busy at their respective posts. However, there are now shirtless people working everywhere on the construction site, and the heat is still radiating from the gap between the rattan helmets on their heads, and everyone is busy at their posts.

A stone crusher makes a rhythmic mechanical sound not far away, and a conveyor belt is feeding large pieces of stone into the rollers of the roller crusher, and the hard stones are quickly crushed into fist-sized crushed stone under the rotation of the rollers, and then sent out from behind the rollers and onto another conveyor belt. There are also workers holding shovels to shovel up the gravel that has slipped off the conveyor belt and throw it back to the crusher conveyor belt, which transports the gravel to a hoist, raises the gravel, and sends it to a two-meter-high bucket, under which is a large impact crusher, which crushes the fist-sized gravel again, and finally falls into the conveyor belt below, and then lifts it to the gravel yard in front for the next step of sorting.

Sun Di is far away and Sun Shu is the enemy of Sun Zhi

Sorting is achieved through a vibrating screen and a screen, the vibrating screen has two different screens, the upper layer is a large mesh screen, which will sort out the crushed stone that is not completely broken and sent back to the front end to be crushed again, and the lower layer is a fine mesh screen, which will screen out the crushed stone that is too fine, and the crushed stone of this size is not suitable for paving, but it can be used as building materials in other places, so it will not be wasted.

The gravel of the right size is loaded onto a small trolley and sent to the front of the road for paving and used as paving stones.

As truckloads of gravel were delivered, a steam crawler tractor drove over with a mill to flatten the gravel. Engineers waiting on the side of the road came up to check if it was flattened and if it needed to add some more stones. Newton is seriously checking the data with the equipment at the moment, he is the youngest boy on the whole construction site, he is only eight years old when he entered the Oriental Port, he has only passed his tenth birthday not long ago, but no one in the audience dares to underestimate this half-sized boy - this Newton is real! Don't look at his size because of long-term malnutrition when he was a child and developed late, but the technology in his hand is real, Bao Bao taught him without hiding at all, and Bao Bao will also teach him all kinds of knowledge about physics, mathematics and geometry when he teaches professional knowledge, children at this age have a good memory and flexible brains, and these knowledge are basically a little bit clear, not at all like those adult students in the education commonly known as training classes. Let the elders of the education department hate to whip them. In just over two years, Newton has been able to take charge of the construction department, and even many naturalized employees of building surveying work have to respectfully call him a "teacher" when they see him - this is not flattery, but Newton is really a little teacher of the surveying training class.

In the past two years, the work of the building committee has been very heavy, especially the bag as the person in charge, it is simply too busy to be on the feet, and it is a luxury to be able to rush back to the dormitory to sleep on time every day, not to mention the time to be trained in the training class below, which is even more painful than killing him, so he is only responsible for teaching Newton - Newton is ten times better than those students with ox heads, and Newton himself understands and then teaches those students. In line with the concept of "the best training ground is the actual operation", Baobao directly arranged the so-called training class to the construction site, and Baobao asked Newton to demonstrate to those students while operating, and after a few times, it was handed over to those students to operate. Newton's main job now is to check whether the data meets the requirements, and most of the work is carried out by the students.

"Okay, almost," Newton looked at the spirit level again, "add two shovels of material to this position, grind it again, and test the data." ”

The construction workers next to them are not strange, there is often such a phenomenon under the rule of the Senate, a group of young half-big dolls holding books while operating, if it is placed in the Wu Dynasty, this is called talking on paper, but here, people do it according to the things in the books, but it is not leaky. Especially those carpentry and metalworking masters, who work according to the old experience of the past, and what they make with a long time is not even as good as what these half-sized dolls make according to the books. After all these fierce battles between old experience and book knowledge ended in failure, the workers who worked like to run after the half-big doll holding the book, because even if they are not their own profession, they can learn a lot of useful knowledge from the book, and can explain the reason for the matter thoroughly, and do what they say, even if it is wrong, it is not wrong.

Xie Mingfang walked over, saw this situation, and greeted Newton warmly, "Newton! Busy? ”

Newton saw that he was an elder, and hurriedly followed a few students around him to stand up and bow to her, "Hello Aunt Chief!" ”

"It's okay, you're busy!" Xie Mingfang watched with interest from the side, and Newton quickly turned around and continued to look at the data. She saw this child on the first day she came, and at that time she didn't understand why Bao Bao casually accepted an apprentice in order to thank the child for his outspokenness, but now it seems that it has completely become a sigh that Bao Bao accepted such an apprentice, and she herself began to feel that she should accept a little apprentice, but she was more resistant to accepting an apprentice, because she had been preparing for pregnancy and wanted to have a child. Tian Hua has been urging her to have a child quickly, don't spend all the most important time on work, and give birth to a child early also gives Tian Hua something to do. She crossed with her mother, which is very rare in the Senate, and it seems that there is only Liu Lihua except her. But this with her mother also has a headache for her, her mother for the reason of loving children, added a lot of interference to her and Yang Minghuan's life, which gave her a headache, and now the family has increased the pressure on her to have a child, which does make her a little breathless, you must know that it has been a year since she got married, and she didn't move at all, which made her run to the hospital several times during this time for examination. The result of the examination was that she had no problems, and Yang Minghuan did not have time to go to the hospital for an examination, which made Tian Hua put all the pressure on her. Thinking of this, Xie Mingfang couldn't help but sigh, turned around and walked towards the track-laying machine not far away.

The track-laying machine was specially produced by Zhang Yuan's heavy industry laboratory, but this track-laying machine is not a fully automatic product as the construction department wants, but a semi-automatic model. Underneath the track-laying machine is the track chassis, which can walk directly on the broad gauge, and behind the track-laying machine is three carriages, in which layers of sleepers and steel rails are placed. There is also a truck crane at the front end of the carriage, which can assist in manually lifting the track into the laying groove. There is a feed port at the rear end of the track laying machine, and the workers put the sleepers vertically from the feed port one by one, and the sleepers are transported to the front of the track laying machine in the conveyor belt behind the feed port, where they are then turned 90 degrees by the mechanical parts, and then placed on the gravel track bed, and then after the laying is completed, the track laying machine will pull out the 20-meter-long rail and transport it to the laying trough, and then push forward through the pulley in the trough, and then be placed, and then fixed on the sleeper with screws. Most of the work was done by the steam engine that accompanied the vehicle, but many of the critical tasks had to be done by hand. The workers ran back and forth with tools, checked whether the sleepers and rails were placed, and then stepped forward to screw the rails on the sleepers with a socket wrench, and it didn't take too long to complete a 20-meter-long track laying work.

Don't look at the current laying rhythm is relatively high, but it exceeds the speed of laying the track bed, at the moment the stone required for the laying of the track bed has to be transported from several quarries in the labor camp of the Oriental Port, the transportation department at this moment has no trucks, even if it is used to transport trucks can only carry less than 600 kilograms of goods at a time, it is simply useless in the laying of the track bed, so it can only rely on train transportation. And now the internal transportation lines of the Oriental Port are all single-line, and in the vast majority of cases, we can only wait for everyone to rush to transport more stones when they are not needed. Now the quarry has to face another problem, that is, there is not enough labor re-education personnel.

With the exception of life imprisonment convicts who worked to death, the vast majority of convicts sentenced to labor have now completed their sentences, and the "prosperous era" of one after another re-education through labor quarries and coal mines has gone forever. Except for those who have died in the course of their labor, no one wants to leave this place at all times, and with the exception of a small number of those who have been released at the end of their sentences, the number of criminals who are still serving their sentences is too small to meet the needs of these quarries to run at full capacity.

Stone is not easily imported from outside, especially through the Medeno people, and is too luxurious, so it is best mined locally. Xie Mingfang, who has no experience in the management of such large quarries, has no choice but to hand them over to the civil affairs committee in Yusha, who will assign personnel to supervise production.

Yusha is dissatisfied with the fact that the quarry has always been produced by criminals, which is too inefficient. Since the staff were criminals, they could not be given good tools, and it was not possible to use civilian explosives in the production of the quarry, so the mining was inefficient. After taking over the quarry, the Civil Affairs Committee first transferred a group of naturalized people who had been released from prison to work in the quarry. The naturalized people were horrified and psychologically resistant to being thrown into the quarry or even the same quarry again, but after two days of production they discovered two very different treatments in the same quarry. In their new jobs, they were able to use explosives to mine the huge rocks, in addition to tools such as steel drills and hammers. The watchtower at the quarry was also demolished, and there were only workers around them, and there were no guards who used to pull over when they saw a break with a whip in their hands, and they didn't need to work for a while to get a bamboo stick to exchange for food. But even so, the quarried stone still can't meet the needs, because the production capacity has increased, and the demand will only increase higher, so that Yusha often laments that Dongfang Port is a black hole of resources, and you can't see the bottom of how much you throw into it.
