The wood is repaired with a knife, and the surface is very smooth, but it is particularly long, and the thickness of the wood is about the same.

It looks like we're about to get to work.

These logs don't need to be unloaded, just open the valve device at the back and let the wood roll down by itself.

Some of these logs can't be rolled down, and they just need human help, and then let them roll down slowly.

Mo Yu didn't help, and one person had already quickly got the wood down, and then the carriage was gone.

The horseman who pulled them over also began to take the lead and prepare to work, and said to Mo Yu's third brother next to him: "You tie that big thick rope to your body, and let the little brother next to you pull you when the time comes, and you go into the water to see the situation first." ”

When Mo Yu heard such a task, he immediately felt that he was very stressed, and it was impossible to introduce such a character without pressure.

If you do some heavy physical labor, it will be like this, but after all, you are responsible for other people's lives, although the current of this river is not particularly turbulent, but the depth seems to be not shallow.

So Mo Yu suddenly felt that the burden on his body was very heavy.

asked the third brother next to him what he should do: "Third brother, how can I hold you?" ”

This person could see that Mo Yu was a little worried, and then made a very relaxed expression: "Oh, I don't want you to pull me personally, do you see a device like that with a round log next to you?" ”

According to the direction pointed by the third brother, Mo Yu took a slight look and saw a round piece of wood stuck in the ground, and it was very strong, and there were many thick ropes wrapped around it.

Mo Yu nodded and said, "Oh, I saw it, how did I get it?" ”

The third brother replied to Mo Yu's words: "It's okay, you don't have to be afraid, it's very simple and simple, I tied that rope around my waist, that round log, and that rope has a head, so it doesn't matter if you can't pull it, but what I need you to do is if I can't swim, you need to pull me up, most of the time I can control my own actions, mainly for fear of accidents." ”

Mo Yu understood at a glance that this should be to deal with those activities that go into the water when the current is more urgent, and when the water is more urgent, there is no way to control his body shape when he is still underwater, so for a long time, he must use this thing to help the people below control his body.

Then the third brother also took a hollow plant, the stem of this plant was empty in the middle, only a section of the thing, and pierced the thing in the middle of the section, so that this thing could be used as a tool for underwater breathing.

The third brother took a few and put them on his waist in case of emergency.

Then Mo Yu started this work, he helped the third brother tie the rope on his waist strongly, and actually made a metal piece on his waist, the metal sheet is very soft and can be wrapped around the third brother, mainly because he is afraid that the rope will be too tight and strangle the whole person, and this thing is used as a buffer.

And in order to prevent the rope from falling off, a small card slot was specially made on the metal sheet, so that the rope was fixed around the metal sheet, so that the rope would not run around.

This equipment stretched out a little, and then Mo Yu and another person helped the third brother slowly descend from the river, it seems that the third brother often does this kind of work, and he didn't feel the slightest inappropriateness in the process of falling.

The whole person looks very relaxed.

The third brother rubbed his hands and made himself warm first, and when he reached the water, the third brother turned into a loach, and fell under the water at once, and through this cyan water, he could see that the third brother was swimming to the bottom of the bridge.

The person who helped Mo Yu next to him was afraid that Mo Yu wouldn't understand, so he explained to Mo Yu first: "You don't have to work too this thing, if you turn too hard, the third brother below will not be able to swim, although this rope is not particularly absorbent, but if it is too long, it will be quite heavy, so don't add more pressure to the third brother." ”

Mo Yu was also a little nervous about doing such a thing for the first time, and then nodded at this person: "Brother Xingxing, I understand." ”

"This job is very easy, and when the time comes, your third brother will tell you how to do this work, let's go over there first and put the wood down, don't forget."

In fact, the more he said this, the more Mo Yu felt that he should be very nervous.

I also saw this device at one glance, and the other looked at the third brother all the time, and the third brother showed his head from time to time to breathe and then spent most of his time under the water touching the wood that sank to the bottom of the water.

The bridge is a slab bridge to allow horse-drawn carriages to pass faster, and there is a lot of wood directly inserted into the bottom of the water to support the weight of the entire bridge.

So if the wood underneath rots, then it needs to be replaced slightly.

Listening to what the third brother said, it seems that the workload is still very large, otherwise it would not have been completed in five or six days.

The people below are actually used as an auxiliary, and the main force to hit the wood and insert it into the water still comes from above.

The person below is mainly able to carry out a correction of the wood, and the person in the middle has already fixed and processed the wood.

Gradually, more and more people began to enter the water.

The third brother had already figured out the underwater situation and talked to the leader.

The three of them carried the wood to a water position where the third brother was, and used a rope to make one end of the wood strong, and the three people below, a total of five or six people, went into the water, and the three people held the wood here.

It seems that the three people where the third brother is have dug a small pit underwater, although it is a small pit, it is estimated that it is not small.

Because the three men took shovels and dug underwater for a lot of time.

Then the wood was let into the pit with their assistance, and the wood was straightened, all of which was in Mo Yu's eyes, although Mo Yu's work was not particularly heavy.

But the mood is very, very stressful.

Of course, in addition to this, he also needs help from time to time, does he need to help others?

Put this wood directly next to the other wood, that is, next to the rotten wood, and then listen to what this person has to say, and just cut the rotten wood and throw it away.

I just replaced it with the new wood.

Well, it turned out that the bridge was repaired in this way, and according to the leader, all the wood had to be replaced, which was the legendary building of another bridge, and Mo Yu felt that the workload of building a new bridge was nothing more than that.

It's just a piece of wood, but it takes a lot of time.

When the wood is fixed to the edge of the bridge, it is necessary to put another log down on the other side of the symmetry, and then put a crossbar in the middle to make the two pieces of wood stronger.

Of course, it's not just this crossbar, but there is also a cross of wood, but it's all very high, and it also needs to be done well underwater, so that it can't be complicated enough for boats to pass through, and the wood needs to be fixed.

It took a morning to hold the group with two pieces of wood, and the two thick logs were completely placed next to the rotten wood of the bridge.

Then someone hung a rope and went down, and when they reached the middle of the bridge, they cut the log and fell into the water to let the river float.

It doesn't matter where the wood floats, it's not something they need to do.

Mo Yu counted the number of these woods, and a total of twenty pieces of wood needed to be replaced from here to the other side of the river, and it seemed that the five or six days that the third brother said were almost true.

At noon, Mo Yu started to eat before he had done much work, and suddenly felt that he was uneasy about eating this meal, because he spent most of his time watching from above.

There is almost no work, and those very heavy hard work are all done by others, so there is no need to say more about the weight of that piece of wood, there are three or four hundred catties.

In fact, after replacing these rotten logs, it is almost passable.

They also deliberately let a carriage with heavy loads walk on it, listen to any unusual sounds, and then see if the bridge will emit any unusual behavior.

This kind of thing is obviously more important to the city construction hall, even if these workers don't check this matter, but as the personnel of the city construction hall or the city lord, this matter must be strictly guarded.

This way of building a bridge is actually not the best way, it should be considered more time-consuming and laborious, and the way like an arch bridge is still more comfortable.

It's just that the length of this bridge is a bit far, which means that the width of the river is relatively wide, and it is not particularly safe to make an arch bridge.

Because of such a long distance, it is difficult to achieve a balance, although the pressure on the arch bridge is relatively large, but the technical conditions are a little too limited.

In the relatively wide rivers, this kind of flat bridge is still the main one, as long as there is no heavy water, it can basically withstand a lot of heavy loads.

And it is relatively simple to build, it seems that these people have to build for half a day, but if you really let an army do it, the unique logistics team in the army, in fact, it takes a morning of work to completely do.

This kind of thing is to throw the two iron chains first, and then fix the two iron chains on the wooden board, and then fix the wood on both sides after fixing the wooden board, and then fix the wood fixed on both sides through the horizontal wood, as for the iron chain, it is directly embedded in the wood, and even said that it can be pulled out.

It was made on a very simple wooden bridge.

It is also under more pressure, and it is very suitable for horse-drawn carriages and large troops to pass.

It is even said that if it is expedited, the safety of personnel is not considered, that is, the work of two emptiness.

All you need to do is have two people swim over and fix the chain, and the bridge is basically complete.

It's just that the bridge facilities in the polar country are relatively developed now, and this bridge can not pass through other bridges, and the dependence is not particularly strong, and the main thing is that there is no need to be so anxious.

It's not particularly good to have a meal at noon, stewed Chinese cabbage and then millet soup, steamed buns are basically enough, and there are some small pickles to adjust their appetite, and some people also bring some unique sauce.

Mo Yu can also eat it, and it feels very fragrant when eating in the wild!
