A kilometre up the Swan River estuary, a small new city has been completed, and if you look closely, you will find that at the bend of a river, a dam more than five meters high has been built.

It is no coincidence that the modern reinforced concrete dam has appeared, but rather the Manchester City power supply project, which was already under construction a year ago, and which is where the final hydropower plant will be built.

Originally, Zhou Jun and Lin Youde, the chief engineers of the construction submitted a report on a thermal power plant, but the executive committee directly sued them for drawing the report, on the grounds that the construction cost was too high and the investment was huge, and asked them to come up with a plan for water conservancy construction.

It is not easy to come up with a plan for the construction of a hydropower station, and almost none of the technical personnel in the city have been involved in the construction of a hydropower project, let alone an engineer.

At this time, a Korean compatriot named Kim Sung-ho volunteered, saying that he had worked in a hydropower plant for a period of time and understood some basic construction requirements.

As for his own major, he actually does not have much to do with the hydropower major, mainly engaged in the design of intelligent machine tools, and is also familiar with and hobby from steam engines to electrical machine tools and machinery. He also studied in Japan and Germany, and then returned to China to develop and join a scientific research unit because he felt that the motherland needed talents like himself more.

Kim Sung-ho is 32 years old and usually a workaholic, old-fashioned, and stubborn. No jokes in earnest. He has a very old researcher's style of doing things, and he will definitely complete what he recognizes, and he once created a record of 72 hours in the post in order to research a project.

In the face of such a talent, the Ministry of Industry has long made a record, but he has been in You Nanzhe's shipyard for the research and development of steam engines, in addition to being relatively low-key, few friends, if not this time in the internal recruitment notice, he volunteered to sign up almost everyone will forget that there is such a number one technical talent.

The basic requirements for the construction of hydropower stations are site selection and topography, we basically know that the power generation of hydropower stations depends on the flow of water to generate electricity, and whether the local topography and landform are suitable for construction, if it is in the earthquake zone, it is necessary to take the design scheme of earthquake-proof measures, which are the basic requirements.

In fact, aside from the difficulty of construction on the water surface, in fact, the construction of hydropower stations is much easier than thermal power stations, hydropower station power generation through high water level water, through the water diversion system into the plant to promote the hydro-generator set to send out electricity, and then through the step-up transformer, switch station and transmission line into the power grid, the general process is like this.

But it is easier said than done, but in fact, it is actually difficult to build, especially the construction of water retaining dams in the river channel, and it takes a long time to fill the landfill.

For example, the dam that has now been constructed has encountered great difficulties at that time, and finally the method of the ancestor Li Bin when he built Dujiangyan was successfully solved.

Since we only need to build a small hydroelectric power station, and we don't have the capacity to cut off the entire Swan River, why not build a water diversion dam in a low-level place to let the water flow in.

It was at his mention that a reinforced concrete dam with a height of about five meters had been built.

On the construction site, hundreds of natives were working hard to transport sand and rocks to the embankment under the watchful eye of a group of heavily armed army soldiers, while in a workshop not far away, An Lan was holding a drawing and exchanging something with Kim Sung-ho.

"Lao Jin, this is my design drawing, the water wheel room is here, and this is the transformer room. In addition, we plan to plant some green vegetation here, you can see how it goes, if not, I will modify it. ”

At this time, Anlan has been on this construction site for nearly a week, almost eating and sleeping here, and Lin Youde, Zhou Jun and others, he is responsible for the design of the soil and water construction plan, and some things must be designed or modified on site in combination with the local situation.

Jin Chenghao dragged down and looked at the construction design drawings, and said thoughtfully: "Basically, it meets the conditions, but it can't be done here, and it's a little close to the water wheel room." ”

Following the direction of Jin Chenghao's finger, An Lan looked at the location of the transformer room marked on the drawing that it was indeed too close to the water wheel room.

"Angong, in fact, there is no problem with your design, but we can leave as much vacant space as possible in some places to leave some space for the second phase of the expansion project in the future, which is much better than re-demolishing it or selecting another site at that time."

Jin Chenghao, who has studied in Germany, generally takes into account the convenience of future improvement and maintenance in the research, so he also opened the design drawing of Anlan without leaving enough space, once the hydropower station wants to be expanded in the future, it is necessary to demolish and rebuild the location of the transformer room by adding a hydro turbine, otherwise it can only be relocated, at least within dozens of kilometers of the hydropower station, it will not be suitable for construction.

Therefore, Jin Chenghao's proposal is very right, fully considering the future, but it can't be said that An Lan didn't expect it, but the leader of the construction unit where he used to design a one-time project was used to it, and now he can't change his thinking.

Hehe, I didn't think it through, I'll revise this drawing. An Lan said apologetically.

"It's okay, we are not in a hurry, this plan will be changed later, you better rest for a while, you have been doing design drawings these past nights," I didn't have a good rest. Jin Chenghao persuaded while handing over a cup of tea to An Lan.

"Hey! There is no way, the task pressed by the executive committee, if we do not complete it, we will be punished, the hydropower station construction project has been carried out several, and now it has only reached one-third of the progress, which has seriously restricted the industrial development and progress of Manchester City, and if we are not responsible, we will be attacked immediately. ”

With a helpless expression, An Lan took the tea handed over by Jin Chenghao and said.

"But I don't think it's anything, even if some things are in a hurry, it's useless, we still have to go step by step in a down-to-earth way, and now everyone is a little anxious to get everything in place in a short period of time, and they don't consider the consequences of pulling out the seedlings like this."

Looking at Jin Chenghao's disdainful expression, An Lan finally knew why this guy was not reused by the Ministry of Industry, but went to You Nanzhe's shipyard, and it was that kind of tendon thinking that people couldn't accept.
