Friday, July 7, 1634, Porter, Songzhou.

There is still a week to go, which is the annual summer harvest period, and now the farms from Porter City to Jiangkou Town have all become a sea of gold, countless wheat is still grasping the final ripening sprint, and the total number of spring wheat in the suburbs is more than 80,000 mu. It is conservatively estimated that at least 22,000 tons of wheat will be harvested in Porter City and Jiangkou Town this year, and thousands of northern farmers are smiling and squinting in advance, and the harvest of various crops has long been ready.

On the west side of the Bojiang Highway on the northwest outskirts of Porter City, in the threshing floor of a farm, a tall, strange steam machine with four wheels stands quietly in the center like a giant beast, surrounded by a dozen workers in blue overalls.

The steam monster is a mixed structure of iron and wood, nearly 5 meters long and 2 meters wide, with two pairs of steel wheels with guide ribs in the front and large in the back, with a total weight of nearly 9 tons. This is the Huamei 20 horsepower steam tractor, which is now the third test this year, and once the experimental steam monster numbered 04 completes all the test items this week, the first generation of Huamei steam tractor will be officially put into production.

Cao Zhe, who became independent from the North Industries Company, became the leader of the state-owned heavy machinery company after defecting to the state-owned energy and mining group. Soon after, several cross-skilled people, including Qin Zhaohe, the chief steam machinery engineer of General Industries, also defected with their own closed disciples, and the state-owned heavy machinery company finally embarked on the road of independent development.

In the direction of choosing a product project, Qin Zhaohe, who has the most abundant experience in steam engine manufacturing in China, still persuaded Cao Zhe, a junior brother who planned to regain face in a steam turbine. The state-owned Heavy Machinery Company turned its attention to the development of steam tractors, which were just being approved by General Industries at that time.

As soon as he heard that he was going to fight with General Industries Company for technology and time, Cao Zhe, who had not swallowed his grievances at the beginning, nodded on the spot. In the spring of 1632, with the financial support of the parent company, the Type 01 test car with a single-cylinder horizontal 20-horsepower steam engine finally rolled off the assembly line before General Industries, although there were many structural design problems. The failure rate is also very high, but it still passed the technical application review of the Science and Technology Commission, and a number of key patents were obtained, and Jiang Zhaolong finally avenged Jiang Zhaolong.

I thought that General Industries Company and North Industries Company would be very depressed about this, but in essence, Qin Zhaohe, who was the chief engineer of the steam tractor project, knew very well that Jiang Zhaolong and Lin Youde seemed to be "atoning for their sins" in this matter. In fact, these two companies provide a large number of parts and components required for steam tractors, and even if large-scale production is carried out in the future, GM and North are also the main suppliers of parts. Even he suspected that Jiang Zhaolong and Lin Youde already had a bigger goal. And did not take the "little toy" of the steam tractor in his eyes.

Subsequently, the project team led by Qin Zhaohe of the state-owned heavy machinery company carried out product improvement work, and after three phased overhauls, the No. 04 car was finally named the official name of the 34 type steam tractor, and began to carry out the final practical test.

Today is a test of the breadth and continuous walking of the fuel, with all kinds of rotten wood, straw, leaves, and low-quality coal stuffed into the fuel furnace. The steam starts to heat up. With a whistle, Qin Zhaohe, who was standing in the driver's seat of the No. 04 steam tractor, personally pulled out the marching device. The steam-spewing monster began to drive smoothly, then went uphill, reversed, and finally hung a tow bucket full of heavy loads and circled the entire threshing field at a speed of more than 5 kilometers per hour.

"Haha, one qiē is normal, the previous problems are solved!" After more than three hours of tossing. The performance of the No. 04 steam tractor has been tested, all the key components are in good condition, Qin Zhaohe, who is over 40 years old, jumped off the car excitedly and hugged the workers around him.

Former member of the Agriculture Committee of the Community Council. Aunt Hai Huifen, who has now retired from the Senate, is stroking the steam tractor in front of her with tears in her eyes, and her fingers are trembling slightly. It is no longer possible to express the joy of the heart.

"Mom, start today. We've got a tractor! After celebrating with the workers, Qin Zhaohe ran to Hai Huifen again, still smiling like a child at his only elder, "In the future, we can save a lot of manpower and pack horse and animal power, whether it is ploughing, sowing seeds or doing transportation trailers, the efficiency will be directly increased by more than five times!" ”

"You kid, you forget your family when you have fun. How many days have you not been with your daughter-in-law and children? ”

After crossing over, Hai Huifen regarded this cousin as his own son. Now that more than ten years have passed since the catastrophe, there are several grandchildren, and this family has really become a bit like what it was before the time-travel, and Hai Huifen is also quite content.

"Hehe, we'll go back tomorrow and get together as a family!" Being reminded like this, Qin Zhaohe touched the back of his head at this time, and only then did he think of his precious children, and his feelings rose even higher.

……

Now in the thirteenth year since the founding of the People's Republic of China, the total population of China and the United States has swelled from more than 124,000 in December 1630 to more than 230,000 by June 1634. Among them, there are more than 144,000 Chinese, more than 75,000 Europeans, and more than 11,000 Indians. This was due to the influx of Chinese and European immigrants totalling more than 18,000 per year since 1629, as well as the "worryingly high" birth rate of more than 220 native newborns.

Correspondingly, in just a few years, the population of Mancheng, the capital of China and the United States, has increased from more than 43,000 in 1630 to more than 67,000 today, and more early towns have also exceeded the 10,000 mark. If it weren't for the fact that the first phase of construction had not been completed in the eastern part of the capital, Long Island, and the addition or expansion of cities and towns around the country, the country would not have been able to accommodate such a surge in migrant families.

After the accumulation of the People's Republic of China 13 years ago and various pains, Huamei has basically met the basic conditions for large-scale population expansion, but how to solve the problem of effective population growth without affecting the national economy, people's livelihood and social stability has become the most important problem and contradiction at present. Cities and towns are already facing hidden pressure on national employment, and the proportion of minors in the country has also climbed by 28%, which is both happy and nervous.

With the input of more modern agricultural machinery and animal power, the manpower demand of large state-owned or private farms has been further reduced, and the output of domestic agriculture, forestry, animal husbandry and fishery has been enough to feed twice the belly of the current population. In 1634, the domestic price of wheat had fallen below $80 per tonne. Before the "Grain Export Restriction Act" that was implemented in 1627 was completely liberalized, blindly expanding the scale of agriculture could only further reduce domestic grain prices, thereby greatly harming the interests of the peasants.

On the other hand, although the basic scale of the country's modern industry has gradually entered a mature period, the number of industrial workers on which it depends is still insufficient to expand explosively. The number of qualified technicians who can be obtained from formal vocational education channels and on-the-job training is only two to three thousand each year, and the overall industrial development is still constrained by the supply of raw materials and the number of skilled workers. Therefore, simply expand the scale of industrial investment. It may not be a good means to effectively solve the employment problem of a large number of new immigrants.

One of the core of the country's second four-year development plan is to encourage the private sector to form private construction companies to undertake large-scale national public infrastructure construction, so that the additional migrant labor can be used to improve the country's basic national strength. The development of core cities and towns that are related to the grand strategic direction, especially a number of large-scale projects for the development of local resources and military security, have been put on the agenda. It was officially launched in fiscal year 1634, with a total investment of more than $5 million over the next four years, and all walks of life will benefit from these national projects.

In addition to the second phase of the water diversion project in the capital city, the flood control embankment project in the towns along the Song River and the Fu River, the land reclamation project on the Qingcheng Peninsula, the mining road in Shangji Town (later known as Poqipu Xi City on the east bank of the Hudson River), and the Fuhe Bridge, the most exciting project is the White Horse River Bridge Project in Jiangkou Town.

……

The Baima River in the north of Jiangkou Town, the upstream of the river experienced a heavy rain not long ago, and now the river is tumbling and gurgling, and the waves are like thunder.

On the northwest bank of the river in the town of Eguchi. The joint construction team of the state-owned construction engineering group and the Oriental Construction Company is making final construction preparations for the first modern cross-river bridge project in China.

The construction of a bridge across the river from Jiangkou Town to connect the land on the north bank of the river is an important goal of the second phase of the country's current northern strategy. At the same time, it is also a major test of road and bridge engineering construction technology. Under the design of Zhou Kai, the first road and bridge engineer in China and the CEO of Oriental Construction Company, the first modern bridge in China will adopt a cable-stayed structure.

There is an island in the middle of the Hakuba River in this section, so the Eguchi Bridge is actually composed of two sections. The two sections of the bridge have a combined length of more than 300 meters, and the pier bases will be constructed of reinforced concrete. The upper layer is then riveted with the main structure of the bridge body and the bridge columns of the steel frame structure, and then the bridge body at both ends is firmly pulled by the iron chain cables of the bridge columns with several strands of intersecting and jointing. The bridge deck will be built with large reinforced concrete precast elements. In order to ensure the safety strength of the bridge deck load.

The design of the Jiangkou Bridge is quite modern and forward-looking, and its complexity and construction difficulty have far exceeded the original "Blue Bridge" in Butterfly Island Twin Ports City and the highway bridge in the mining area of Beiyuan Town, Haizhou. The amount of steel and concrete used alone is more than double that of the two bridges combined. Not to mention the riveting technology of the large structural parts of the main bridge column and the bridge engineering mechanics involved in the cable-stayed iron cable, no matter which one it is, it is the first time that the country has done it since the founding of the People's Republic of China for more than ten years. The so-called advanced machinery that can be used is only a few heavy steam tractors or cranes, and some inland waterway vessels.

Although some people have proposed the traditional scheme of using reinforced concrete and stone, the construction technology is relatively mature, low cost and more safe, and it has been applied to the road bridge in the mining area of Beiyuan Town, Haizhou, and the Fuhe Bridge with a longer span connecting Fuhe Town and Dongfu Town will also be this scheme. However, after careful consideration, the Science and Technology Commission agreed to Zhou Kai's bold design. After all, this kind of engineering will be a rare opportunity to exercise and try many current technologies, especially the processing and riveting of large metal components.

Such a high-end and high-grade bridge project is the core project of the country to stimulate domestic demand, cultivate road and bridge technology construction talents, and consolidate the northern strategy. It will not only serve as a ready-made engineering internship site for many majors at universities and higher vocational colleges, but will also provide a large number of jobs for northern towns that have already exposed their labor surplus. To this end, in the past few months, the state-owned construction engineering group has recruited thousands of new workers from the new immigrants from northern towns, and the Oriental Construction Company has also expanded by several hundred people, preparing to start construction on the north and south banks of the Baima River and the island in the middle of the river at the same time, with an estimated construction period of 24 months and a total investment of more than 1 million US dollars.

In fact, the Jiangkou Bridge project was proposed as early as 1631 shortly after the end of the Second Iroquois War, and was originally intended to reassure the residents of Porter City and Jiangkou Town, to prove that the state attaches great importance to the north, and more importantly, to develop land resources on the north bank of the White Horse River, but due to financial pressure, this plan has not been realized.

A few years later, the construction of a major bridge over the White Horse River has finally begun, and local officials and residents in Porter and Jiangkou have indeed been overjoyed, because it means that the local economy will be greatly boosted. To this end, the local governments of Porter City and Jiangkou Town have also specially brought together the heads of local enterprises in related industries to mobilize everyone to improve product quality and production efficiency, and try to strive for all kinds of demand orders in bridge construction projects to fall locally.

On Monday, July 10, 1634, a signal flare from the commander-in-chief of the Eguchi Bridge project hit the sky, and more than 1,000 construction workers on both sides of the river started work at the same time, and a huge bridge-building movement was officially staged. As early as two months ago, a battalion of the National Defense Force had been deployed north of the White Horse River to defend the country's core strategic interests.
