Release that Witch

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 fill the foot of the pier?" Lotus looked at the rolling river and asked with surprise, "Don't you plan to build a real bridge instead of a pontoon?" Connect the two ends of the river?"

“Well,” Roland spread 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 slow down the impact, they need to be processed like this.”

"This is... the look of the ship," Lian moved his eyes back to the drawing.

“Yes, it’s a spindle type,” he nodded. “As long as it is parallel to the direction of the water flow, its front is minimally impacted. The problem is that the Chishui River is nearly ten meters deep. Can you let the river rise? ?"

"It's not difficult to do it, Your Highness," Lotus said replied crisply. "Give it to me."

To be on the safe side, the ship responsible for carrying the witch is the township. The large concrete hull is flat in the river, the helmsman is still lightning, and the sail power is provided by Wendy.

However, in the past week, when the latter saw the prince, they would slightly look away, which seemed uncomfortable. To this day, Roland only saw that she looked up and looked at herself as usual, and when she passed the board, he heard a soft "thank you".

"You have to remember this credit on me," the nightingale in the fog whispered in his ear.

The township quickly left the dock and headed towards the center of the wide river. Carter had pulled up the twine on both sides of the river, and the two red belts on it were expected to be erected. After the cement boat traveled to the first point, the lotus stood on the edge of the ship and began to exert its capabilities.

I saw that the river suddenly seemed to be boiling, and they all surged upwards, forming a "mountain package." In a short while, gravel, grass roots and silt emerged from the raging river, and the water gradually became muddy.

So, Roland thought that her ability could not only transform the solid ground, but also the water, and it would be easier to raise the water surface than the loose gravel. Although the rising river immediately rolled around, the riverbed had been lifted a little.

Not long after, a group of blue-gray soil floated out of the water, it looked very soft, and it smelled an unpleasant smell, and everyone could not help but hold their noses.

However, in Roland's eyes, this is a good fertilizer. For centuries, the bones of fish and other aquatic organisms, water plants, and the dung of the residents have been deposited in the soil. If it is not inconvenient to transport, he would rather use the soil for fertilizer. Unfortunately, it can only be shoveled by hand and thrown directly into the river.

In this way, the first layer was cleaned up, and he finally saw the solid yellow-brown soil. The next step was to repeat the process until all the two pieces of land were trimmed.

Roland expects the process to last at least a week or so, but the land is lifted out of the water and means it can be used directly. The flowing river will continue to take away the sediment. Even if it is not protected, even the spindle-type land will not be able to. Over ten years.

He called Carl Vanbert to his side, took out a charcoal pencil, and painted while telling how the ground should be cured.

“What do you mean by digging a groove at the edge of these land and pouring it into the cement?” asked the Minister of Construction today, drawing a drawing.

No loss is an outstanding member of the Wangdu Stonemason's Association. Roland satisfactorily thought that he simply reminded a few words and he immediately understood his intentions.

“Yes, 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 drop the groove by one meter. Repeatedly, a cement wall can be formed directly into the bottom of the riverbed. "This program was thought out after Roland saw the ability of the lotus. Since she can control the ground to fall straight, it must 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 washes away the outer dirt, it will be blocked by the tightly wrapped walls."

Roland nodded. "The key point is to control the overall height of the sink. If it is less, it will lead to the bottom of the package. If it is too much, it will waste cement and delay the construction period. This is up to you."

"Yes, Your Highness," he said. "Count the mud and soft soil dug up. I guess the whole height should be around 12 meters."

"In addition, after the cement wall around the four walls, the middle land should not be covered with cement. I will plant flowers and plants in the future." The prince shouted.

"Growing...Flower?" Carl groaned.

After all, these walls can't be dripped, and if they are built in sections, there will be a uniform gap on the wall. The easiest way to further stabilize the soil is to plant grasses that balance soil moisture and reduce soil erosion, especially the ultra-long root weeds after the leaves have been modified to ensure that the soil is firmly consolidated.

A brief explanation of the soil conservation of the plant, Roland turned to look at the busy workers on the river bank, "How is the bridge part now built?"

“The cement gravel road is being laid,” Carl said without hesitation. “It should be completed this week.”

According to the plan, the approach bridges on both sides of the river are made of masonry cement. Just like the west wall, as long as the positioning and measurement work is done, the construction itself is not difficult. The bridge ramp is increased by seven meters relative to the ground. It is connected to the city street by a long curved **** with a curvature. In addition, the height difference between the river bank and the water surface should be 10 to 10 with the Chishui River when the iron bridge is completed. The net height of two meters is basically enough for the inland river sails.

At present, the main bridge has only completed one span, and the main frame is tested on the shore. Because the span is not large and the load is extremely low, Roland does not care about its reliability even if it does not know anything about the bridge project. In the eight rounds without overloading, the 30-cm-high I-beam is a solid guarantee. Even if it is crowded with people, it is impossible to break the steel beam. What's more, from processing to assembly welding, Anna is one-handed, and the probability of appearing tofu project is extremely low.

Similarly, its installation is also very simple. After the three-span main bridge is prefabricated, it will be lightly weighted by the hummingbird and then delivered to the lightning bolt.

When the steel bridge that can accommodate two four-wheeled carriages side by side stands on the Chishui River, the two sides of the North and the South are truly connected as a whole.

“Even the greatest stonemason, it’s hard to imagine such a magnificent bridge,” Karl said with a wide-angled lake. “His Royal Highness, is there a name for this steel bridge?”

Roland thought for a moment, "Just call Chishui Bridge." (To be continued. Your support is my greatest motivation.)
