How to build a bridge on such a wide river?

The bridge in Alin's impression is also the kind of single-plank bridge, the longest is about ten steps long, this river surface, at least one mile wide, how to repair this bridge!

He subconsciously looked at the woods behind him, and then felt a little puzzled: "Build a bridge on such a wide river?" ”

There is no tree in this world that is a mile long, so what can he do to build a bridge?

Seeing his appearance, Zhao Hao couldn't help but laugh and reprimanded: "Why are you so stupid, I didn't let you build that kind of high bridge, the bridge I asked you to build is similar to the dock, a little higher than the water, just cross the bridge of the carriage, is it difficult to repair?" ”

It's about the same as this pier?

Ah Lin subconsciously looked down, and suddenly he was stunned.

It turned out that the stump was driven first and then the planks were laid, this bridge was built like a wharf, it was not very difficult, after all, he had built a barrage fish dam with Zhao Hao, and he still had experience in this area.

He thought for a moment, and then asked cautiously, "Great Chief, can I use the divine soldiers with Sister Ayun?" ”

With the divine soldiers in hand, it is easy to cut down trees, and in this way, the speed of building bridges is not known how many times faster.

This kid is not stupid with a melon seed, and he also knows how to borrow divine weapons.

Zhao Hao nodded without hesitation and said, "No problem, I'll let Ah Yun borrow a divine weapon for you to use." ”

Building a road is relatively simple, but the distance is a bit terrifying, Ah Hua thought for a while, and asked carefully: "Can I borrow a divine weapon with Ah Yue, after all, it is a bit slow to open the road alone, and if Beishan can join me, the speed will be much faster." ”

This is also a trivial matter, anyway, it is useless for Ah Yun and Ah Yue to hold the divine weapon at this time.

Zhao Hao still nodded without hesitation and said, "Okay, I'll let Ah Yue lend you the divine weapon." ”

After this discussion, the matter was roughly decided, Zhao Hao was about to raise his hand and order everyone to go back and organize people to start construction, but Ji Rushuang suddenly asked: "Husband, you build such a bridge on the river, how can the big boat pass?" ”

They have to go to the south of the river every day, and after the big ship sends them to the place, they will come back to help transfer supplies, that is to say, the big ship they sit on has to pass through the middle of this bridge several times a day, how can the big ship get through such a low bridge?

When Zhao Hao heard this, he was immediately embarrassed.

This is a question he did ignore.

However, he knows a lot of solutions, such as raising the bridge high, and for example, making a section of the bridge deck active, and lifting the bridge deck when the boat needs to cross.

The method of raising the bridge is obviously not very good, because the highest part of the big ship is several meters above the water surface, and there are people standing on it, that is, if you want to raise the bridge, it will be about ten meters high.

In this way, the length of the stump under the bridge is a bit terrifying, and the longest stump is afraid that it is not more than 20 meters.

Even if they could dig such a long stump into the water, the strength would be a big problem, and he didn't want the bridge to be wobbly.

Zhao Hao thought for a while, then picked up a branch, and while drawing on the ground, he explained: "In this way, let's make the middle section of the bridge deck active, which is about six steps wide, tie a strong cowhide rope at one end, and make a solid base at the other end to drag, and then erect a strong beam on the base, the height is almost six steps, so that when the boat wants to pass through this section of the bridge deck, just call a few people to pull up this section of the bridge deck, and when the boat passes, put the bridge deck down." , and it won't take much time, and the carriage can still be crossed on the bridge deck. ”

This method is really novel, Ji Rushuang listened to it, and her eyes couldn't help but shine again.

Of course, there is a premise for this method, that is, the manpower to pull this bridge deck is large enough, and the bridge deck is nearly ten meters long, and the weight is not light.

Fortunately, the manpower at this time is generally relatively large, and the elite soldiers of Haotian Department are even more powerful than a thousand catties, so it is not a problem to pull up such a section of the bridge deck.

Otherwise, he would have to find a way to make a hanging hoist, which would be troublesome.

Zhao Hao was not verbose, after the discussion was completed, he led everyone back to the valley, borrowed magic soldiers from Ah Yun and Ah Yue, and asked Ah Hua and Ah Lin to gather a group of people, and then waved his hand and ordered, start construction, repair the bridge, and open the road.

The efficiency of the elite of the eighth battalion of the Haotian Department is not covered.

As soon as each tree fell, a team of men and horses rushed up, drew iron knives and cut down, and the branches on the trunk were quickly cleaned up.

Ah Hua and Beishan Ah Mu took dozens of subordinates and rushed to the opposite shore by boat, and soon, the big trees over there also began to fall in rows, and the people and horses here were also squeezing on the big boat rowing back in waves, rushing to the opposite bank.

Zhao Hao took Ji Rushuang to stand on the dock and watched silently for a while, then took out his divine weapon and said to Ji Rushuang: "Let's go help Ah Lin and them." ”

With that, he took the lead and jumped off the dock, rushed into the woods next to him, brandished his divine weapon, and slashed at it.

Seeing this, Ji Rushuang hurriedly ran over, pulled out the divine weapon, and cut it down with him.

In fact, it does not take too much wood to build such a bridge across the river, it is calculated according to a pair of stumps in six steps, and a distance of one mile also requires fifty pairs of wooden piles, and the big trees in the mountains of the South Barbarians are generally twenty or thirty meters high, one is cut down, the thicker part at the bottom can be used to make wooden piles, and the thinner trunk at the top can be used to make planks on the bridge deck.

That is, it is almost enough for them to cut down three or four hundred trees.

This amount is simply not a matter for Zhao Hao and them, the three divine weapons waved together, and in less than an hour, the river bank by the wharf was densely lined with processed tree trunks, and it was estimated that there were more than four hundred.

The next thing should be to nail the stump, Ji Rushuang has always been curious about this, such a wide river, such a deep water, how can they nail the stumps to the other bank in rows?

After all, people can't exert force when they stand on the water, and even if they stand on a boat, they can't exert force.

This Zhao Hao had already thought of a way when he built the barrage fish dam, he took Alin with him, chopping and chopping and assembling, and soon, several simple wooden frames of different heights were completed.

Immediately afterwards, Zhao Hao and Alin carried a relatively low wooden shelf, walked directly to the dock, and threw the wooden shelf into the river next to the wharf.

Zhao Hao still decided to keep this wharf, after all, the structure of the wharf is still a little different from the bridge deck, and it is a bit of a waste to use it directly to make the bridge deck.

As for the bridge to the other side, just repair the pier next to it.

This simple wooden frame is Zhao Hao's magic weapon for nailing tree stumps, and people like him with a strength of tens of thousands of catties directly stand on the wooden frame and lift the stump into the water, and the stump is basically nailed!

The speed at which he nailed the stakes was so fast, one at a time, one at a time, and Alin only had to lead someone to carry the stumps and simple wooden frames for him constantly.

In this way, with their full cooperation, in less than a day, the wooden stakes were miraculously lined up on the opposite bank, which stunned Ji Rushuang.

Of course, the bridge connecting the two sides of the strait is not completed, and the amount of work to pave the bridge deck is large.

However, Zhao Hao doesn't have to care about these anymore, and it is more than enough for Ah Lin and them to do this.
