Reborn in the 70s as a military doctor and meets a special soldier

Although Lu Jiu didn't know what the old man meant by this, he still cooperated with him and soaked in the river for a long time.

After basically touching every stone, the old man asked him to go ashore.

However, Lu Jiu also discovered a problem when he touched the rocks. He originally estimated that the water level had risen by about 30 centimeters, but in fact the depth of the pile of strange rocks was no longer above his head.

Theoretically, the water level on this rocky beach shouldn't be so deep. The only possibility is that all the pebbles underneath have been washed away, so the water level has become deeper than expected.

However, if the stones here are washed away, where will they go?

Furthermore, how much water should be needed to wash away the stones?

The water on the tidal flat has always been gentle. When did it become so undercurrent and extremely fast?

Lu Jiu's face became solemn.

Lin Musen looked calm: "Looking at your expression, what extra gains are there?"

Lu Jiu opened his mouth, not knowing what to say.

After all, this is just his personal perception, and there is a suspicion of misjudgment. At this juncture, everyone's focus is on railway delivery. What if he reports this nihilistic concern to his superiors, causing them to distract their attention and waste manpower and material resources.

Just when Lu Jiu was thinking about investigating and reporting again, Lin Musen spoke slowly.

"You also noticed that the rocks on the beach are moving, right?"

"!" Lu Jiu looked at the old man in surprise.

Lin Musen picked up a wooden branch and drew it on the ground. Lu Jiu recognized it carefully and couldn't help but be surprised.

This is the Jinsha River topographic map, and this old man is so familiar with it.

Lin Musen finished the drawing hastily and clicked on a few places: "These places are places with rapid water flow, because there are underground rivers flowing in here, so the river water is extremely fast.

However, it starts to calm down again here, because there is a mountain stream blocking the river at this place. The main channel is here, and the tidal flat is a tributary. However, the tributaries of the tidal flat merge again downstream, and the water flow is fast again.

I have to say that this is the right place for you to build a bridge. It is the gentlest section of the Jinsha River at present.

However, the water pattern is not fixed. It will change over time. In addition, the frequent mudslides in Aqiong Mountain accelerate its change.

If there is a gap in the mountain stream, the current on this side will become larger, and the stones on the beach will continue to be washed downstream.

One hundred meters ahead is the location of the pontoon. If you go to the pontoon and explore now, you will definitely find a lot of stones. "

"you……"

Lu Jiu was very surprised. He originally thought that Lin Musen was an expert and scholar in the field of natural resources and minerals, but now after hearing his remarks, he suddenly felt that he was not.

"Formal introduction, I am from the Survey and Design Institute of the Ministry of Transport. The Jin-A line railway is about to be opened. I am here to do the delivery assessment and inspect the surrounding road conditions." Lin Musen introduced himself with a smile.

Lu Jiu stood up straight in awe.

The Survey and Design Institute was not an important department with authority in later generations, but it is a very important department for the current country.

After all, the motherland is full of wastes that need to be renovated. Railways and highways need to be built, and the Survey and Design Institute is the unit responsible for planning and building these places.

If the motherland is compared to a person, the land is the human body, and the railways and highways are the blood vessels and meridians that connect the human body. Without the normal blood supply of blood vessels and meridians, the human body's organs cannot function normally, and it is no different from a dead person. .

This shows how important the Survey and Design Institute is.

"So you..."

Lu Jiu felt a little embarrassed when she thought that Teacher Lin was about to go into the water, but she forcibly stopped him.

Of course, he was not annoyed at stopping Teacher Lin, but if he had known the identity of the teacher earlier, maybe his attitude would have been softer, instead of being as tough as before.

Teacher Lin didn't care very much. He would rather accept Lu Jiu's iron-blooded suppression than Xiaoping's crying, making trouble and hanging himself.

"I'm a road construction worker." Teacher Lin puffed up his chest proudly: "A very professional one. I went to the Soviet Union to study!"

Lu Jiu: "Disrespectful."

"You're welcome, just let me do it boldly from now on."

"..." Lu Jiu. Oh, are you waiting for him here? If he hadn't experienced his reckless one-stop operation just now, he would have believed it.

Although Teacher Lin is very professional, if he really dares to do it, he is afraid that he will be covered with a national flag in the next second.

Lin Musen didn't know that Lu Jiu had seen through his mind, and he didn't plan to say more. He just planned to boil the frog in warm water. After all, such a young man couldn't use too much force, and it was best to be subtle.

He fooled around a bit and continued talking about business.

"We need to go to the Jinsha River diversion area to check the situation first. If the gap in the mountain stream is not large and the mountain is stable, there is no need to worry. If the gap is loose, it must be leveled and reinforced in time.

Do you know where that place is? "

Lu Jiu nodded: "The bifurcation is about ten hours away from here."

First of all, it's far, and secondly, it's difficult to walk there. There are no factories or stations there. Lu Jiu only went there when he was looking for a way. It's still a wild jungle there, so it takes some effort to get in.

Lin Musen nodded: "It seems that we can't make it now. Let's go tomorrow. You also pack your luggage tonight. This time we will go to the mountain for at least three to five days and as long as half a month. In the end, it will be a vote if we all go in." Solve it and save time wasting going back and forth.”

"Okay." Lu Jiu nodded obediently.

After reaching a consensus, the two continued forward and went directly to the pontoon.

At this time, Lin Musen looked at the pontoon and checked the strength of the pontoon. He couldn't help but smile at Lu Jiu.

"It's okay, it's pretty solid."

Lu Jiu was a little embarrassed: "I come here every month for maintenance and troubleshooting."

However, he only took care of the bridge, but did not pay attention to the changes in the water flow. This time when he went into the water, he focused on the bottom of the river, and sure enough he discovered changes. There was indeed a lot of stones accumulated around the bridge.

Lu Jiu couldn't help but feel uneasy.

"Have you ever learned to build bridges and pave roads before?"

When Lu Jiu was silent, Lin Musen broke the calm again.

Lu Jiu ignored the uneasiness and nodded: "It's just that the army has learned some knowledge about combat preparedness and emergency response."

"Even for combat preparedness and emergencies, you have learned basic theory. It seems that you have laid a good foundation." Lin Musen smiled again: "Building bridges and paving roads is to facilitate people's daily travel. Since it is for people If you use it, it will definitely have a service life. It is too harsh to worry about it breaking. For example, you can't worry about an enamel cup for the rest of your life just because it may break, right?

If it breaks, just rebuild it.

The bridge is the same, and the road is the same. There is no use worrying. No matter how perfect the design is, it can't avert natural and man-made disasters.

Instead of worrying, it's better to identify safety hazards and extend its life yourself, don't you think? "
