In fact, there has never been a real consensus in the Executive Committee on whether to implement the time-consuming and labor-intensive project of hydropower station construction in the early stages of the crossing, and this topic has become the focus of controversy in almost every meeting before the crossing. The objections were mainly due to the fact that the project would take up a lot of human resources, and that almost all other projects would have to be stopped in order to take care of its priorities during the construction period. In the eyes of later generations, this is at most a small project of small hydropower projects in rural areas, but for the people who travel through this time and space, it is a bottomless pit that is enough to exhaust all manpower. Some people believe that instead of treating technicians from various departments as low-level labor, it is better to do a good job of other infrastructure projects first, and wait until there is sufficient manpower to build hydropower plants. Besides, if there is a slight problem in the construction, and the rainy season and flood season are not over, then it will be a big deal.

The industrial party scoffed at the fact that there were no coal resources in Sanya, and that even the steam engine could not be used on a large scale at the beginning, and if hydropower generation was not carried out in the early stage, then where would the power output needed for the construction of the industry come from? Otherwise, step by step, step by step, we have to rely on the manpower of the people to build infrastructure, and after a year or two, everyone is still in this ravine as migrant workers to farm and move bricks, so what is the point of spending so much effort to cross over?

As for the construction period questioned by the other party, in the end, Liu Shanxia of the Ministry of Construction stood up and made a package ticket, claiming that as long as the personnel and materials were in place, the main project of the hydropower station could definitely be won before the flood season arrived.

In the end, the well-founded Industrial Party gained the upper hand, and the entire initial construction plan, whether it was the deployment of personnel or materials, was unconditionally inclined to the hydropower project. When the task force returned to Base No. 2 from Lai Tong, except for some members of the Military Police Department who were responsible for patrolling the perimeter and the elderly, women, and children, the large troops of the Crossing Group were all requisitioned as laborers, and even the headquarters of the Executive Committee was moved from Base No. 1.

Sixty or seventy fishermen recruited from the vicinity have now become full-time workers on the construction site, and in addition to carrying various materials, a small number of them who have the skill of weaving have to be responsible for weaving a large number of bamboo cages day and night, which will be used to intercept the flow and build cofferdams during construction.

After the Ministry of Agriculture directed the labor camp to open up 200 acres of wasteland on the east bank of the Tiandu River and plant all kinds of vegetables, these dozens of Ming prisoners were also escorted to the construction site of the hydropower station. Although I don't know what the shorthairs are going to do, seeing the mountains of various materials here, plus hundreds of shorthairs going in and out, the captives also know that these shorthairs are probably going to do a big job here.

And the first thought that subconsciously flashed in Luo Shengdong's mind, could it be that these shorthairs want to build a city in this place? But after thinking about it, it seems unlikely, the stockade built by shorthair by the sea is obviously not completed, why rush to the upstream to build a city, and the terrain here does not seem to be ideal for building a city. But seeing the steady stream of logs, sand and gravel, bamboo cages and other utensils being transported, it was clear that there was a big project to be carried out, and Luo Shengdong was also deeply puzzled by this.

The men in the labor camp were soon assigned to work in a nearby quarry. It is said to be a quarry, but it is actually the location of the Tiandu iron ore mine. The people of the Ministry of Industry can be said to be careful in their calculations, quarrying while making preparations for the excavation of Tiandu iron ore, perhaps the hydropower station has not yet been completed, and the iron ore here has already entered the mining stage. This place is only three to four hundred meters away from the construction site of the hydropower station, and the logging team has already carved a road from the forest, so that two wooden trucks can pass side by side. Cai Hongzhan, an old carpenter, took people to work overtime and built 30 board cars in five days, although the process was a little rougher, but fortunately, the terrain was flat and the distance was close, so there was no need to worry about shaking off the frame in three or two clicks.

And almost all of the Li people who came here with Fu Li stayed. Fu Li saw with his own eyes that those fishermen could receive white rice and salt from the short-haired Han people after their work every day, and didn't they just sell their labor? How could such a good thing be missed, but we in Li Tong had a large amount of labor force that could be exchanged for grain and salt! Therefore, under the encouragement of Ning Qi and others, Fu Li also asked people to rush back to Fu Shan Tong and inform them to send more young and strong laborers.

Three or four days later, there were hundreds of Li people who had arrived from the nearby mountains. With so many Li people coming to the construction site, once the communication is not smooth, it is easy to have conflicts. Zhou Hengxing had to set up a temporary bilingual teaching class after finishing work in the evening, teaching some vocabulary that could allow the two sides to communicate simply. And Ningqi is also on the verge of launching the first "Li District Hope Primary School", which will be admitted to the school first by the ** Li children who come to the construction site with their parents, and the key training object Fu Li is of course also among them. Of course, it is unlikely that any knowledge will be imparted at present, and even if literacy is too difficult for these Li children who have not received basic education, Ning Qi's main teaching task now is still the same as Zhou Hengxing, trying to teach them some simple Chinese conversations to ensure smooth communication.

In view of the large number of local workers involved in the construction, the Executive Committee had to set aside some of its manpower to build several bamboo scaffolds near the construction site for the temporary accommodation of these workers. The task of the cooking team also increased rapidly, and they had to cook more than 100 meals a day. Fortunately, in order to trade, the nearby Li people continuously sent all kinds of vegetables and fruits, mountain delicacies and fresh game, and the cooking team did not have to worry too much about the lack of sufficient ingredients.

In order to do its best to complete the battle, the executive committee also tried its best to concentrate all kinds of materials to the No. 2 base. With the exception of the New World, almost all of the ship's diesel generators were removed and transported along with several high-power pumps. Sailors from the shipping department even risked capsizing by transporting two Jessebo multi-purpose excavators and two Bobcat multi-purpose vehicles to the construction site by water in large wooden rafts. With the help of several construction vehicles, the transfer speed of materials on the construction site has also been greatly accelerated. And this became the focus of the local natives in the next few days, they had never seen this kind of strange car that could drag things by themselves without pulling a horse-drawn ox, and the rumors of "the short-haired master would do it" were rampant for a while.

On April 17, 1627, the second day of the third month of the seventh year of the Great Tomorrow Apocalypse, the first real major project after the crossing, the Tianduhe Hydropower Station, finally broke ground.

The gimmick of a leader holding scissors to cut the ribbon in later generations is definitely out of place in this time and space. The members of the executive committee stood in the river on the bank and worked together to erect a sharpened log, and Yan Chujie stood on a high shelf and nailed the log into the river with a sledgehammer, thus opening the prelude to the construction.

Because there is a natural river bifurcation at the dam site, this greatly simplifies the construction steps, saves the trouble of building a diversion canal, only needs to intercept the flow at the river channel insertion to establish a cofferdam, and the river water is all introduced to the river on the other side, and drain the water of the river channel on this side of the dam site, and you can start to build the dam body. With an average depth of only four to five metres, it is not very difficult to intercept the river.

According to the instructions of the technicians, the migrant workers erected wooden stakes more than two feet long at regular intervals, and then drove them into the bottom of the river with sledgehammers. Construction was carried out from both ends, and a sparse fence was soon erected on the seven or eight meters wide river. Then a large bamboo cage filled with stones is transported from upstream to the fence and thrown near the fence by a small boat, so that the wooden stake fence can stop the bamboo cage and soon form an underwater dam.

Nearly 100 large bamboo cages filled with stones have been connected to form a simple cofferdam emerging from the water, and it is obvious that the amount of water flowing through this river has decreased a lot, and the water level downstream has dropped by at least two or three meters. At this time, the migrant workers began to pile up the fence wall to fill the gaps, using more wooden stakes to fill the gaps little by little. The intake heads of several high-power pumps have already penetrated deep into the bottom of the river, and they have begun to quickly drain the water behind the cofferdam, and the pumped river water flows into another river channel through the guò pipe, leaving the onlookers in amazement.

By four o'clock in the afternoon, the water in the river near the dam site had been drained, but the silt at the bottom of the river was still one or two feet thick, and it would take at least hundreds of people to dig for a whole day. However, the project commander did not have the patience to wait for the silt to be cleaned up slowly, and the commander-in-chief Liu Shanxia asked people to lay bamboo and wooden springboards from the bank to the middle of the river, and then asked the migrant workers to step on the wooden springboard and start laying a large tarp behind the wooden stake fence, and then build the main body of the cofferdam with sacks of soil to plug the small leakage that had been sparsely pulled. In order to build this earth-encircled weir, the preparatory committee also specially added a linen bag of 2,000 and a special tarpaulin of hundreds of square meters to the material procurement, which has now come in handy.

In view of the current abundant labor force, the project headquarters decided to start work day and night, implement three shifts, and continue to supply lighting with diesel generators after dark, so that migrant workers can go down to the river to clean up the river silt. Several LED headlights on both sides of the river and on the cofferdam illuminate the entire construction site, and this kind of lighting installation without open flames makes the new migrant workers who only come today amazed, and they suddenly became convinced of the original skeptical remarks of the first comer's "short-haired old man will do it".

The project went unusually smoothly, and the dredging of the river bottom, which began the next day, did not encounter any major problems. Once the silt has been removed, the site where the dam is located is exposed to a complete rock base. Liu Shanxia said proudly to Xiang Zhinan: "Look, this is the advantage of doing the preparatory work in place! There is no need for too much investigation, just apply the distribution map of water conservancy projects in later generations." ”

Xiang Zhinan Zhengse said: "Don't be too happy, the cofferdam blocking the water is only the first step, and the real project has just begun." Your boy has made a military order in the executive committee, and it will be completed before the flood season this year. Let's go, let's go down and have a look. ”
