Chapter 262 The Bridge on the Chishui River

8days ago Xuanhuan Novels 9
A week later, Roland officially launched the steel bridge construction project.

You mean, let me raise two pieces of land in the middle of the river to serve as the foothold for the bridge piers?Lian looked at the rolling river water and asked in surprise, "Are you planning to build a real bridge instead of connecting the two ends of the river bank with a pontoon bridge?"

Well, Roland spread out the paper roll in his hand. Considering the impact of the river, the two pieces of land need to have a certain volume, and in order to reduce the impact, they need to be processed like this.

This is the look of the ship, Lian turned her eyes back to the drawings.

That's right, to be precise, it's a spindle shape. He nodded, as long as it is parallel to the direction of the water flow, its frontal impact is minimal.The question is, the Chishui River is nearly ten meters deep, can you make the bottom of the river rise?

This is not difficult to do, Your Highness, Lian simply replied, "Leave it to me."

To be on the safe side, the ship responsible for carrying the witch was the Town, the wide cement hull was on the ground in the river, the helmsman was still lightning, and the sail power was provided by Wendy.

However, in the past week, the latter will slightly look away when he sees the prince, making him feel a little uncomfortable.

Until today, Roland saw her looking up and looking directly at him as usual, and when he was passing by on board, he also heard the other party's soft thank you.

You have to remember this credit in me, and the nightingale in the mist laughed in his ear.

The town quickly left the dock and headed towards the center of the wide river. Carter had already pulled up hemp ropes on both sides of the river, and the two red cloth belts tied on it were the expected position of the piers.

After the cement ship reached the first point, Lian stood on the edge of the ship's side and began to display her abilities.

The river suddenly seemed to boil, surging upwards, forming a mountain bun.

After a while, gravel, grass roots and silt emerged from the surging river water, and the water gradually became turbid.

So that's it, Roland thought that her ability not only could transform solid ground, but also included water, but it would be easier to lift the water surface than loose gravel.

Although the rising river water immediately rolled down around, the riverbed had been lifted up little by little.

Not long after, a ball of blue-gray soil surfaced, looking very soft and emitting an unpleasant odor. Everyone couldn't help but cover their noses.

However, in Roland's eyes, these are all good fertilizers. For hundreds of years, the bones of fish and other aquatic organisms, aquatic plants, and residents' feces have been deposited little by little in the soil.

If it is not inconvenient for transportation, he would rather use this soil to fertilize the fields.

Unfortunately, now it can only be shoveled away manually and thrown directly into the river.

Just cleaned up a layer and lifted it up, and he finally saw the solid yellow-brown soil. The next step was to repeat the process until all the two lands were trimmed into shape.

Roland expects this process to last at least about a week, but just lifting the land out of the water and means it can be used directly. The flowing river water will continue to take away mud and sand. Without protection, even spindle-shaped land will not last for more than ten years.

He called Carl Vanbert to his side, took out a charcoal pen, and described how to solidify the ground next.

You mean, dig out grooves on the edges of these lands and pour cement into it?The Minister of Construction asked now, gestured to the drawings.

It's no loss for him to be an outstanding member of the King Capital Mason Association. Roland thought with satisfaction. After just a few simple reminders, he immediately understood his intentions.

That's right, the length of each section should not exceed five meters, and the depth should be controlled at about one meter.After filling the cement, let the witch lower the groove by one meter. Repeat this way, a cement wall inserted directly into the bottom of the riverbed can be formed.This plan was thought out after seeing Lian's ability. Since she could control the ground to fall directly, she would probably be able to bring the structures built on the ground into the ground.

Your idea is so clever, Carl's eyes lit up, so even if the river water washes away the outside soil, it will be blocked by the tightly wrapped wall.

Roland nodded, the key point is to control the overall height of the sinking. If there is less, the bottom will not be tightened. If there is too much, it will waste cement and delay construction period. You are responsible for controlling this.

Yes, Your Highness, he replied, including the digging of silt and soft soil, I estimate that the entire height should be about twelve meters.

In addition, after the surrounding cement walls, the land in the middle should not be covered with cement. I will plant flowers and grass on it in the future.The prince reminded.

Plant...flowers?Carl was stunned.

After all, these walls cannot be leaky, and if they are constructed in sections, there will definitely be even gaps on the wall.

To further stabilize the soil, the easiest way is to plant grass vegetation to balance the soil water content and reduce soil erosion. Especially the super-long root weeds after the leaf magic modification, which can ensure that the soil is firmly consolidated together.

After briefly explaining the soil conservation function of plants, Roland turned around and looked at the busy workers on the river bank. How is the guide bridge part now?

The cement gravel pavement is being laid, and Carl reports without hesitation that it should be completed this week.

According to the plan, the approach bridges on both sides of the river are made of matte cement, just like the city walls in the West. As long as the positioning and measurement work are done well, the construction itself is not difficult.

The bridge deck ramp is fully raised by seven meters relative to the ground, connected to the city streets through a long and gentle slope with a curve. In addition, the height difference between the river embankment and the water surface, when the iron bridge is completed, it should be able to form a net height of ten to twelve meters with the Chishui River, which is basically enough for inland sails.

The main bridge has only completed one span and is being tested on the shore. Due to the small span and extremely low load, Roland is not worried about its reliability even if he knows nothing about the bridge project.

In the era when there was no eight rounds of overload, the 30-centimeter-high I-shaped steel is a guarantee of stability. Even if it is crowded with people, it is impossible to break the steel beam.

What's more, from processing to assembly and welding, it is all done by Anna, and the probability of tofu shoddy projects is extremely low.

Similarly, its installation is very simple. After all the three-span main bridges are prefabricated, the hummingbird will directly lighten it and then hand it over to the lightning to hoist in place.

When this steel bridge that can be used by two four-wheeled carriages stands on the Chishui River, the north and south sides are truly connected into a whole.

Even the greatest stonemason is hard to imagine such a magnificent bridge. Looking at the wide and shimmering lake, Carl sighed, Your Highness, does this bridge of steel have a name?

Roland thought about it and called it Chishui Bridge.
