Chapter 289 Drainage System

"Xiaowen just follow what you said, now design a functional plan for the whole city for me, you should have no problem with this, right? You can scan the construction of so many cities around the world, and then absorb some of the advantages. Pen ~ Fun ~ Pavilion www.biquge.info" Zhao Chen said very simply.

"No problem, first of all, I can delineate a general functional area for you, according to Mr. If this area you choose now is used as an industrial park in the future, it is also possible, just right, our geographical location, in winter, the west wind and northwest wind are more common, the industrial park is set in the southeast of the city, part of the pollution will not drift into the city, of course, in fact, this for us, it doesn't matter at all, the city tree can absorb these air pollutants. ”

"But all the roads in the whole city may have to be completely rebuilt, in addition, the most important thing is the underground drainage system, which is more important, but according to my data exchange with the City Tree, with its ability, in the later stage, it can improve the control of the Yellow River riverbed, so that the Yellow River bed is more than ten meters lower than the current one, so that we can directly discharge the drainage system into the Yellow River." Xiaowen said quickly.

"As you said, you first generate a map for me, and then tell me where the factory is built. Zhao Chen thought about it and said very simply.

"That's fine, but there's one thing you might have to spend money on first, sir. Xiaowen said very simply.

"What a problem. Zhao Chen immediately asked.

"It's the groundwater system you just mentioned, what level of groundwater system are you going to build, sir? Xiaowen immediately asked.

There is no doubt about the importance of the groundwater system to a city, and now many cities in China, especially in the central part of the country, and some cities in the south, once it rains, especially heavy rain, the groundwater drainage facilities will be directly blocked, and then the water on the road, some low-lying areas are more than a few meters deep.

If you want to build the largest city in the world, this is not possible.

"I want the best in the world, and I have one request, according to the standards of heavy rainstorms, and I want to have no water in the city for a week of heavy rain. Zhao Chen said very simply.

"Hee-hee, it's not hard to do, but one thing, that's that you need to spend money. Xiaowen rarely laughed twice.

"What kind of trick?" Zhao Chen asked curiously.

"The underground drainage system is not domestic sewage, because it is basically rainwater, snow water, etc., so it can be directly discharged into the Yellow River or underground river, but the discharge can not catch up with the heavy rain, because when it rains, the rainwater accumulates very quickly, and the precipitation is difficult to achieve complete drainage even if we increase the drainage efforts, so we need a huge reservoir under the city, as well as a drainage system that is directly discharged to the underground river. ”

"This is the construction of an underground drainage channel that I found. Xiaowen directly projected a photo on Zhao Chen's mobile phone.

Zhao Chen looked at the photo in his mobile phone, a little speechless, because of this photo, if it wasn't for Xiaowen saying that this was a sewer, Zhao Chen would have thought it was a tunnel.

"With the use of super reinforced concrete, plus a part of the soil layer reinforcement, and the help of urban trees, the sewer built in this way, even if you throw a nuclear bomb on it, it will not collapse underneath, so it can also be used as an urban bomb shelter. However, if you want to save money on such a sewer, depending on the size of the city you want to build, the easiest way is to hire an excavator to dig directly into the ground, build it inside, and finally bury the earth. Xiaowen gave a solution.

Zhao Chen was speechless for a while...... Damn, the city doesn't even have a shadow, so let's dig and build a sewer first? Damn, I've looked through the city's construction cases all over the world, and I don't think I have done this.

And to build a sewer of this level?

"How much is it expected to cost?" Zhao Chen couldn't help twitching the corners of his mouth as he asked.

"If we use our construction team, it will cost about 40 billion, and if we use an external construction team, it will cost about 200 billion RMB, but the time will be more than 4 times faster than our own work, unless you exchange ten more construction teams, sir. Xiaowen said very simply.

200 billion! The corners of Zhao Chen's mouth twitched, 200 billion to build a sewer network? This Nima is too extravagant!

"It's too expensive, isn't it? Zhao Chen still couldn't hold back and asked directly.

"This is how we dig directly into the ground to build, and if we have a city on top of it, to build a sewer of this scale, I'm afraid this money will be tenfold. Xiaowen added.

2 trillion, the corners of Zhao Chen's mouth twitched. If you want to develop a city in such a short period of time, this infrastructure cannot be left undone, but it is just ...... How to choose between 200 billion and 2 trillion...... This is really a problem, and it may cost ten times more to do it later, but at that time, there are already funds back, and the pressure is not great.

And spend it first, even if Zhao Chen now has a baby software company in his hand, but this is also more than a year's capital income, and Zhao Chen can't do anything else for more than a year, so all the money can be thrown into it.

"Okay, I'm out of the way, isn't it just a sewer? Dig it! Anyway, it's going to lay the foundation for the whole city!" Zhao Chen said decisively.

"Well, sir, maybe I didn't make it clear, the 200 billion I just said is the cost of materials, not the construction cost. Xiaowen added.

Zhao Chen: "......"

According to the price of material construction is almost halved, that is, this figure will be doubled?

"It's done!" Zhao Chen rolled his eyes, and said that this is it, isn't it just money? Money is a fart!

Originally, Zhao Chen wanted to directly exchange the car factory, but now it seems that it is not so fast, at least Zhao Chen has to build the sewer under the factory first, but for the time being, it is enough to directly use the two construction teams exchanged by Zhao Chen.

"In this way, you first delineate the scope of the automobile manufacturing plant for me, and then draw the sewer structure below for me, and first send a construction team to build the sewer, and I will buy the materials I need. Zhao Chen said decisively, time is urgent, he has now borrowed some funds from the system.

"The drawings have been generated, and I will send you a detailed bill of materials in a moment, sir. Xiaowen said immediately.

"yes, I see. Zhao Chen nodded, since it can't be exchanged now, then Zhao Chen won't talk nonsense, he drove directly to turn, and then continued: "Xiaowen, you say hello to Liu Yang, and then you send a construction team to dig up the ground first according to your construction drawings." ”

"Yes, sir. ”

After instructing Xiaowen, Zhao Chen directly took out his mobile phone, and looked at the list of materials sent by Xiaowen to Zhao Chen, mainly special high-grade cement, plus sand and gravel raw materials, and sand and gravel These raw materials must be selected The hardest granite is the best, in addition, fly ash, F ore powder, slag, silica powder and other mixtures are also needed, in addition, the steel bars used in the reinforced concrete are all special steel bars directly listed by Xiaowen.

After reading this, Zhao Chen touched his nose, it seemed that he was still underestimating reinforced concrete, originally Zhao Chen thought that reinforced concrete was nothing more than cement, sand and gravel, and then mixed with steel bars. But now it seems that there is too much knowledge in this, and what Zhao Chen said is only the most basic concrete, and it is also the most ordinary.

But now it is obvious that the concrete required by Zhao Chen is not at all achievable by ordinary concrete, and Zhao Chen deliberately did not see it, the reason why only raw materials are purchased is because the construction team has a high-tech concrete mixer truck systematically produced, and these high-tech, high-temperature mixed concrete mixer trucks can be manufactured Some of them cannot be applied practically on the earth now, and can only exist in the laboratory of high-strength concrete.

However, now, this steel is not an ordinary production of steel, but a steel that needs special processing, of course, special processing refers to the proportion of additives in the steel, not to say technology, its technical difficulty is not high, any medium-sized steel plant can do it, but since you want to find, then find the best.

And in Inner Mongolia there is a large steel plant, located in Baotou Baotou Steel.

After determining the target, Zhao Chen immediately went directly to Baotou, of course, it was impossible to drive over, so naturally he flew over. However, after flying, Zhao Chen picked up the phone and dialed the owl again, it seems that it is better to contact the owl directly? Some troops have special cement used in them, in this way, if the military goods are directly used, the quality is guaranteed, and there is no need for Zhao Chen's family to run.

The phone was quickly connected, "Hey, what's the matter?" the owl picked up the phone and asked directly without greeting.

"How's my security guard?" Zhao Chen didn't go straight to the point, but asked about the things mentioned earlier.

"I have submitted it to the above, and the above has agreed in principle, some details are being discussed, and after the discussion, it is expected that the first batch of 300 veterans, all of whom are special forces, but in terms of age, there may be some old, the oldest is forty years old, and the youngest is thirty-two years old. The owl said immediately.

Zhao Chen nodded, this age is understandable, because the general service period of special forces is 12 years, but in fact, except for a few, most of the special forces end up as ordinary policemen, and the salary is not low, but the salary is not high.

And the above allocated 300 to Zhao Chen at one time, after all, it is really difficult to arrange the professional problems of these soldiers. The most important thing is that it is not easy to find a job with a high salary, good benefits, and good future development.

"Then I still have some things, I need a batch of special cement, special steel bars, please help me contact it, I will go to Baotou in a while, I want to contact you directly, after all, the military also has procurement, in this way, it can be in place at one time, without me talking about each factory." Only then did Zhao Chen say his purpose. (To be continued.) )
