"That's it!"

Pointing to the valley on the top of the mountain, Zhu Guoqiang said to Ge Shizhen.

"That's where we set up the reservoir."

Power is the mother of industry, although there are many options such as water wheels and ultra-low head turbines, but after repeatedly consulting the information, Zhu Guoqiang still took the "Wufeng Mountain Reservoir" as a key project to provide power for it, and first prepared a full set of design drawings for the reservoir.

In fact, even for the Ming Dynasty in the twelfth year of Chongzhen, there were no technical difficulties in this kind of small reservoir that was common in the mountainous areas in later generations.

In the other world, construction of the reservoir began in the winter of 1957 and was stopped, expanded, and continued several times, and finally completed in 1968. 10,000 cubic meters of earth and stone, 950 cubic meters of concrete, 850,000 yuan invested by the state, and 460,000 man-days were completed. The total storage capacity is 9.3 million cubic meters, the Xingli storage capacity is 4.9 million cubic meters, and the dead storage capacity is 300,000 cubic meters. The dam is a homogeneous earth dam, with a length of 715 meters, a height of 23 meters, a top width of 4 meters, and a slope protection of coarse stone on the surface of the water. The spillway is located at the south end of the dam, with a width of 68 meters and a maximum discharge capacity of 900 cubic meters per second. The south discharge hole is a pressurized round culvert, with a diameter of 1.4 meters, a discharge flow of 13.5 cubic meters per second, and a flat steel gate. The north discharge hole is a non-pressure culvert, with a cross-section height of 1 meter and a width of 1 meter, a water discharge flow rate of 7.5 cubic meters per second, and a flat steel gate. The designed irrigation area is 8,000 acres, the effective irrigation area is 7,000 acres, and the actual irrigation area is 3,000 acres. The total length of the main canal is 12 kilometers, and there are 13 branch canals with a length of 5 kilometers...... Of course, these canals are not what Zhu Guoqiang needs at the moment.

All he needed was this reservoir, and then use the reservoir as a natural regulating reservoir to build a diversion hydropower station using the drop of the reservoir.

"Reservoir?"

There was a slight doubt in Chen Zhizhao's tone.

"Yes, it is a reservoir, which is directly here to build a dam to cut this river, and then use a diversion canal and iron pipes to lead it to the factory area under the mountain, and use hydraulic power to drive the water turbine, and the water turbine drives the sky axis to provide power to the factory......

"But if the river is cut off, will it affect the livelihood of people downstream?"

"It's not completely cut off, and after the water passes through the turbines, it still goes through the drainage canals and into the river."

How much power can such a reservoir provide?

Although the detailed calculation results have not yet been released, and even because of the river runoff and other reasons, it is questionable whether the drawings of the original reservoir can be used, but one thing is certain is that the construction of the reservoir and the installation of water turbines are undoubtedly the cheapest source of power.

Although the people of Chongzhen for 12 years are laymen on how to build modern dams, it is not difficult for Ge Shizhen or Chen Zhizhao, or even most officials, to "rammed earth dams", after all, it is the responsibility of local officials to control the river, which also requires them to know how to govern the river and build dams.

Tens of thousands of cubic meters of earth and rock, 460,000 man-days, seems to be an astronomical amount, but in fact, on average, it is still ...... It takes about a year to build, plus a series of problems such as measuring river runoff, so even if Zhu Guoqiang gets a full set of drawings, this plan can only be put on hold temporarily, but the construction of the factory cannot be shelved.

At the suggestion of netizens, Zhu Guoqiang decided to adopt a simpler diversion power station, uh, no, it should be borrowed from the local method of the fifties and sixties to launch "small hydropower" to provide early power for the factory.

Compared with the barrage dam, the small hydropower project is relatively simple, and the construction period is short, and the results are fast. In the construction, local conditions are adapted to local conditions, and local materials can be used as much as possible. Even the use of wooden water pipes together with the pressure water pipes, especially those "Tufa hydropower stations" in the fifties and sixties, was simply specially prepared for Zhu Guoqiang, because the industrial base was weak at that time, most small hydropower plants used simple wooden or iron water turbines, with generators converted from electric motors, and even in terms of technical conditions, the two worlds were not far behind. Soon, Zhu Guoqiang spent a few yuan in old magazines through "CNKI" to find the design scheme of soil and hydropower, which even has a "standard scheme". First of all, an aqueduct was excavated upstream, and the width and depth of the aqueduct were calculated according to the flow and slope of the water, which had formulas that could be applied, and when these calculations were made, Ge Shizhen, Chen Zhizhao and more than a dozen students from Jinan were all surprised by the arithmetic attainments of the prince, and they also began to study arithmetic. In the past few decades, scholars in the Ming Dynasty began to translate a large number of Western mathematical works, although in Li Zhizao and Matteo Ricci's translation of "Tongwen Arithmetic", the Arabic numerals in the book are translated into Chinese numerals, but also list Arabic numerals, and some works directly use Arabic numerals, Arabic numerals, calculation formulas as scholars, not only did not resist the new knowledge, but gladly accepted, There is even a student in Jinan, Du Mingzhong, who also took the initiative to ask the prince if there are any books in this area, for this reason, Zhu Guoqiang even wondered whether to build a library, of course, these are all later words.

"The aqueduct can be made of stone masonry, and there is no problem with that, the function of this aqueduct is to inject water into the pressure front pool, which is connected to the aqueduct and the pressure pipe. It consists of a forechamber, a trash rack, a gate, an inlet chamber, an overflow channel and a sand outlet......"

When the craftsmen entered the construction site and began construction, Zhu Guoqiang unfolded the drawings and introduced to the more than 20 young people around him, they were all local scholars in Shandong, not only children, talents, and even lifters, the only thing they had in common was that they all lost their relatives during the Qing army. And now, like Ge Shizhen and Chen Zhizhao, they have become Zhu Guoqiang's assistants.

Of course, it is not easy to be an assistant to the prince, and many times, the prince throws them a few drawings and a few beautifully printed books for them to study on their own.

"You should note that this pre-pressure tank is one of the most important components of the "hydraulic station", not only to settle sediment and intercept drifting debris to avoid damage to the turbines, but also to distribute water when there are multiple turbines. In addition, its main function is to regulate the amount of water entering the turbine......"

After all, it is not a hydropower station, since there is no "generator", then remove the "electricity", that is, the "hydroelectric station".

In the next few days, Zhu Guoqiang devoted himself to the construction site of the "hydraulic station", after all, he was more required to participate in the construction here than the factory there. The only hope is that these "students" will be able to get on track as soon as possible and preside over the construction of the project......
