The planning of the dam has been underway, and all the preparations have been done almost.

In this season, the amount of water in Zhu water has decreased and has entered a dry season.

Now that the staff is in place, the time is right, everything is ready, and you can start.

In the wilderness, a huge army is advancing.

The newborn red sun shines on everyone's face in the team, making everyone look red.

In the team, the tribe members were full of spirit, talked loudly all the way, and imagined the future.

The topic of discussion is the dam to be built.

This is a team that drove to the mountain exit of Zhushui River to build a dam, with a total of about 600 people.

The total population is now about 1,400, and the 600 people drawn are all young and strong laborers.

Not only are there people in the team, but there are 60 cows.

The Fangfeng family has 50 heads, and the Huangfeng family requisitioned 10 heads.

These cows pulled a cart, which was loaded with a large number of tools and supplies for building dams.

Ye Qing is also in the team.

Looking at the marching team, Ye Qing was also full of excitement and finally took a solid step to take the tribe to take off.

In order to build the dam this time, Ye Qing made a lot of preparations in the early stage.

Ye Qing made hundreds of carts build by his tribe members.

The frame processing of the tray is relatively easy, and it is still very easy for a tribe to build one in a day.

These carts do not require much fineness, the finished product looks very rough.

The wood on the frame has not been polished on the surface. The raised tree knots are cut off and mortise and tenon are tied to assemble.

These woods simply remove the bark, and some of them are not peeled cleanly.

The only thing is that it is sturdy. The frame material was quite willing to use at that time, and it was all made of straight fir trees.

The carriage is even simpler. If you break the thick bamboo and then fix it with bamboo nails on the frame, it will be the carriage.

The difficult part is in the wheels and hubs.

Ye Qing uses assembled wheels.

He designed and made a sample of wooden strips in a quarter-circular arc shape, and then let the tribe members make a large number of them.

After that, four wooden strips were assembled into a circle, and the circle was coated with fish bladder glue, five layers of dislocation glued together, and then riveted with copper rivets and installed spokes, which became wheels one by one.

The wheel hub is the most difficult place to make, and Ye Qing simply doesn’t make it and cast it directly in bronze.

Although it is a little heavier, it is many times more sturdy than the wooden wheels made by the tribe's craftsmanship.

What is troublesome is the rotational friction problem of the axle.

Now I don’t have the energy to make a lot of bearings, so I can only insert a solid wooden stick into an axle.

If it is worn, just wear it. You can only replace the axle from time to time.

Anyway, making a log axle is easy for the tribe now.

The exit of the dam is a little far from the tribe, seven or eight miles away.

Therefore, the 600 people who built the dam were preparing to eat and live on the construction site.

After all, it takes too much time to go back and forth every day.

People of this era were not so spoiled. They built a batch of thatched huts on construction sites, and these thatched huts would not be worse than the huts they lived in before, or even better.

With bronze tools, it is not difficult to build a thatched hut.

The team walked along the river and built a simple road along the way so that the carts could pass.

There are mostly mudflats and grasslands by the river, with few trees and shrubs. 600 people work together to fill in the potholes, and the road will be completed.

I walked and repaired, and slept on the road all night that night, and arrived at my destination at noon the next day.

The first step is to build a house.

The team was full of young and strong laborers, and they were quick to do things, logging wood, burying pillars, and building beams. In an afternoon, a wooden frame of a house was built.

The unfinished roof is not ready to be covered with thatch.

The next day, Ye Qing asked his tribe members to cut down a large number of bamboos as thick as calves, then broke them in half, removed the bamboo joints, and tied the broken bamboos together to each other flat, and then fixed them on the roof with a rope.

This is the tile.

A broken bamboo is a whole long tiles from the roof to the eaves.

This is much simpler and faster than thatched, and has much better leakage prevention effect.

As for the walls, weave them with fine bamboo or bamboo boards.

Although bamboo and fixed ropes will not last much time to wither, it is enough for the few months of building the dam.

However, this newly built house can no longer be called a thatched hut, but a bamboo house.

It also attracted mountain spring water, solving the problems of drinking water and washing water.

At this point, the accommodation problem is considered a solution.

The dam begins construction.

Zhushui exits the mountain pass, which is a canyon between the two mountains.

The water of Zhu flows out of this canyon.

The mountains on both sides of the canyon are not very steep.

In this place, the river width of Zhushui itself is not very wide, only 20 to 30 meters wide.

However, when the mountains that extend from the river to the two sides reach a height of more than 10 meters, the width between the two mountains has reached nearly 500 meters.

The overall height of the dam designed and built by Ye Qing is 10 meters.

The overall design of this dam is that the width of the dam top is 10 meters, the width of the bottom of the dam is 30 meters, and the length of the dam top is 500 meters.

If calculated in this way, the amount of soil in the entire dam is 100,000 cubic meters.

Of course, there are some ready-made mountains on both sides of the river that can be borrowed, which can save a lot of soil.

After spreading it out, the amount of soil required for each tribe to complete is about 200 square meters.

If it is calculated based on the calculation that each person digs ten directions of soil every day, 200 square meters of soil will take 20 days.

In addition, the time required to carry soil, the time for dam building, and laying the inner waterproof stone slope, the estimated time required may take three or four months.

On the waterproof slope on the inner side, Ye Qing is preparing to lay a relatively thick layer of stone to prevent water waves from eroding and eroding the dam body.

This requires a lot of stones.

Where does the stone come from?

If the tribe members were asked to dig the mountain, the energy and physical strength would be very large.

But hasn't this era been developed yet?

Stone?

Just pick up the stones!

This chapter is not over, please click on the next page to continue reading! Ye Qing asked his tribe to take a bamboo raft, search upstream and downstream along the Zhushui River, and pick up the stones scattered at the bottom of the river along the river.

Although there are not many stones, they are still enough for building a dam.

The first step in building a dam is to build a sluice gate.

Ye Qing built the sluice at one end of the dam, close to the mountain on one side, rather than the middle of the dam, which made the engineering and technical requirements much lower.

Ye Qing used stones for the construction of the sluice.

Considering the relationship between the gate, the built sluice gate is only three meters wide and five meters deep.

Then, considering the relationship between water flow, Ye Qing asked his tribe members to build 10 such gates side by side.

The gate is not big enough, and the drainage is not sufficient?

The quality is not enough to make up for quantity.

Ye Qing will make the gate of the sluice gate directly from logs in the future.

Originally, Ye Qing wanted to use bronze to make it, but after careful calculation, he found that the amount of bronze required was so large that it was scary... it was unaffordable!

If you use logs to build a gate, it is nothing more than rotting too quickly and not long enough to use it. You need to change the gate frequently, which is a bit of a waste of wood.

But there are not many other things in this era, so there is no more wood.

So, waste it is just waste.

After a period of time, the tribe members have already established a certain technical foundation for building stones.

Li and other more skilled tribe members were gathered to build a sluice gate.
