"This is it!"

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

"We will set up the reservoir here."

Power is the mother of industry. Although there are many options such as waterwheels and ultra-low head turbines, after repeatedly reviewing the information, Zhu Guoqiang still regarded the "Wufengshan Reservoir" as the key project to provide power for it, and first prepared a complete set of reservoirs.

Design drawings.

In fact, even for the Ming Dynasty in the twelfth year of Chongzhen, there were no technical difficulties with such small reservoirs, which were common in mountainous areas in later generations.

In another world, the construction of this reservoir started in the winter of 1957. During this period, the construction was stopped, expanded, and continued many times, and it was finally completed in 1968. It required 10,000 cubic meters of earth and stone, 950 cubic meters of concrete, and the state invested 850,000 yuan.

460,000 working days. The total storage capacity is 9.3 million cubic meters, the active 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, 715 meters long, 23 meters high, 4 meters wide at the top, and facing

Coarse stone slope protection on the water surface. The spillway is at the south end of the dam, 68 meters wide, with a maximum discharge capacity of 900 cubic meters/second. The south drainage tunnel is a pressurized circular culvert with a diameter of 1.4 meters, a discharge flow of 13.5 cubic meters/second, and a flat steel gate.

.The north drainage tunnel is a pressureless culvert with a section height of 1 meter and a width of 1 meter, a discharge flow rate of 7.5 cubic meters/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, 13 branch canals, 5 kilometers long... Of course, these canals are not what Zhu Guoqiang needs right now.

All he needs is this reservoir, and then he uses the reservoir as a natural regulating reservoir and uses the height of the reservoir to build a diversion-type hydropower station.

"Reservoir?"

There was a little doubt in Chen Zhihuan's tone.

"Yes, it's a reservoir. You can build a dam directly here to cut the river. You can pile up earth and ram it to build a dam. Then use diversion canals and iron pipes to lead it from here to the factory area down the mountain. Use water power to drive the turbines.

Drive the sky axis and provide power to the factory..."

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

"It is not completely cut off. After the water passes through the turbine, it will still be discharged into the river through the drainage channel."

How much power can such a reservoir provide?

Although the detailed calculation results have not yet been released, and even the availability of the original reservoir drawings is a question due to river runoff and other reasons, one thing is certain, building a reservoir and setting up a hydraulic turbine is undoubtedly the cheapest source of power.

Although people in the 12th year of Chongzhen were laymen on how to build modern dams, it was not difficult for Ge Shizhen, Chen Zhihuan, or even most officials to build "rammed earth dams". After all, managing rivers is itself

It is the responsibility of local officials, which also requires them to know how to regulate rivers and build dams.

Tens of thousands of cubic meters of earth and rock and 460,000 working days may seem like an astronomical figure, but in fact, on average, it still takes about a year to complete, plus a series of problems such as measuring river runoff.

Therefore, even if Zhu Guoqiang obtained a complete set of drawings, the plan could only be shelved temporarily, but the construction of the factory could not be shelved.

At the suggestion of netizens, Zhu Guoqiang decided to adopt a simpler water-diversion power station. Well, no, it should be based on the local method of the 1950s and 1960s to launch "small hydropower" to provide early power for the factory.

Compared with damming rivers, small hydropower projects built by local methods are relatively simple, and the construction period is short and the results are quick. In the construction, local conditions are adopted and local materials are used, and local materials can be used as much as possible. Even wooden water pipes are used together with the pressure water pipes.

Especially those "Tufa Hydropower Stations" in the 1950s and 1960s were specially prepared for Zhu Guoqiang. Because the industrial base was weak at that time, most small hydropower stations used simple wooden or iron turbines with generators modified from electric motors.

, even in terms of technical conditions, the two worlds are not that different. Soon, Zhu Guoqiang spent a few dollars on old magazines through "HowNet" and found the design plan for land, hydropower and electricity. This design plan

There is even a "standard plan". First, a diversion canal is dug upstream. The width and depth of the diversion canal are calculated based on the water flow and slope. There are formulas that can be applied. When doing these calculations, Ge Shizhen,

Chen Zhihuan and more than a dozen students who came from Jinan were all surprised by Shi Ziye's arithmetic attainments, and began to study arithmetic. Zhu Guoqiang was surprised to find that they were no strangers to Arabic numerals. In the past few years, they had

In the past ten years, scholars in the Ming Dynasty began to translate a large number of Western mathematical works. Although in "Tongwen Suanzhi" jointly translated by Li Zhizao and Matteo Ricci, the Arabic numerals in the book were translated into Chinese character numerals, but Arabic numerals were also listed.

, there are also some works that directly use Arabic numerals, Arabic numerals, and calculation formulas. As scholars, instead of resisting the new knowledge, they readily accepted it. Du Mingzhong, a student from Jinan, even took the initiative to ask Shi Ziye if he had such knowledge.

For this reason, Zhu Guoqiang even considered whether to build a library. Of course, these are things for later.

"The diversion canal can be built with stones. There is no problem with this. The function of this diversion canal is to inject water into the pressure forecourt. This pool is connected to the diversion canal and the pressure pipe. The water is inlet through the front chamber, sewage rack, and gate.

It consists of chamber, overflow channel and sand discharge outlet..."

When the craftsmen entered the construction site and started construction, Zhu Guoqiang unfolded the drawings and introduced to the twenty or so young people around him that they were all local scholars in Shandong, not only Tongsheng, Xiucai, and even Juren. The only thing in common was that

, they all lost their relatives when the Qing troops invaded. And now, like Ge Shizhen and Chen Zhihuan, they have become Zhu Guoqiang's assistants.

Of course, it is not easy to be the Crown Prince's assistant. Many times, the Crown Prince would give them a few drawings and a few beautifully printed books for them to study on their own.

"You should note that this pressure forebay is one of the most important components of the "hydraulic station". It is not only used to settle sediment and intercept drifting debris to avoid damage to the hydraulic turbines, but also when there are multiple hydraulic turbines.

It plays the role of distributing water. In addition, its main function is to regulate the amount of water entering the turbine..."

Power station is the name given to this project by Zhu Guoqiang. After all, it is not a hydropower station. Since there is no "generator", let's remove the "electricity", which is a "hydropower station".

In the next few days, Zhu Guoqiang concentrated on the construction site of the "Hydraulic Station". After all, compared to the factory over there, he needed to personally participate in the construction here. The only hope is that these "students" can start as soon as possible.
Chapter completed!
