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 of the pier?"Looking at the rolling river, Lian asked in astonishment, “Are you going to build a real bridge instead of connecting the two ends of the river bank with a pontoon?”

"Well," Roland spread out the paper roll in his hand, "given the impact of the river, the two plots of land need to be a certain volume, and in order to slow the impact, they need to be processed in this way."

“This is the look of the ship,” Lily turned her eyes back to the drawing.

"Yes, the spindle, to be precise," he nodded, "as long as it is parallel to the direction of the current, its front is the least impactful."The question is, the Redwater River is nearly ten meters deep, can you let the bottom of the river rise?”

"It is not difficult, my lord," replied Lille, "and leave it to me."

For the sake of safety, the ship responsible for carrying the witch was the town, the large cement hull was flat in the river, the helmsman was still lightning, and the sail power was provided by Wendy.

However, in the past week, the latter has slightly removed his eyes when he sees the prince, which seems a little uncomfortable.To this day, Roland did not see her raise her head, look at herself as usual, and when he got on the boat and passed, he heard a soft “thank you.”

"You must remember this credit to me," said the Nightinge in the mist, laughing in his ear.

The town soon left the dock and headed toward the broad middle of the river, where Carter had pulled up the hemp rope on both sides of the river, and the two red cloth bands tied on top of it were expected to be the location of the pier.After the cement boat moved to the point, Lian stood at the edge of the ship and began to exert its ability.

I saw that the river suddenly seemed to boil like a general, and they all surged upwards, forming a "mountain bag".Soon, rubble, grass roots and silt appeared in the surging river water, and the water gradually became turbid.

It turned out that Roland thought that her ability could not only transform the solid ground, but also the water contained, but also raise the surface more easily than the loose grit.Although the rising river immediately rolled around, the riverbed had lifted up a little.

Not long after, a clump of blue-gray soil surfaced, looked very soft, and gave off a bad smell, and everyone could not help but cover their noses.

However, in Roland's eyes, these are the best fertilizer, and for hundreds of years, the bones of fish and other aquatic organisms, watergrass, and the feces of the residents have been deposited in the soil.If it is not convenient to transport, he would rather want to use these soils to fatten the fields.Unfortunately, it can only be shovelled by artificial shovelling and thrown directly into the river.

So he cleaned a layer and ascended a section, he finally saw the solid soil of tan, and then repeated the process until the two pieces of land were completely repaired.

Roland expects this process to last at least a week or so, but light lifts the land out of the water and means that it can be used directly, and the flowing river water will continue to take away the silt, without protection, even the spindle-shaped land will not last for more than ten years.

He called Karl van Burt to his side and pulled out a charcoal pen and painted how to solidify the ground next.

“You mean to dig up grooves on the edge of these lands and re-infused with cement?”Today, the Minister of Construction asked with drawings.

Not to mention the outstanding member of the Wangdu Masonry Society, Roland thought with satisfaction, he simply reminded himself a few simple words, he immediately understood his intention.

"Yes, each section should not exceed five meters in length, and the depth should be controlled by about one meter.After filling the cement, the witch will drop the grooves by one meter, so that again and again, a concrete wall that is inserted directly into the bottom of the riverbed can be formed.This program was conceived by Roland after seeing Lian's ability, and since she could control the ground diameter and descend, she must also be able to bring the built structures on the ground together into the ground.

"You think it's so clever," said Karl, "so that even if the river washes away the dirt, it will be blocked by a tightly wrapped wall."

Roland nodded, "The key point is to control the overall height of the sinking, less will lead to the bottom can not be tightened, more waste cement, delay the construction period, this is your responsibility to control."

"Yes, Your Highness," he said, "I estimate that the whole height should be about twelve metres, taking into account the silt and soft soil that has been dug."

"In addition, after the good cement wall around, the middle of the land should not be covered with cement, and I will plant flowers and plants on it."The prince said.

“The flowers...the flowers?”Carl stood still.

After all, these walls can not be dripped without leakage, and if the construction of segments, there will be a uniform gap in the wall.To further stabilize the soil, the easiest way is to plant grass vegetation to balance the soil moisture, reduce soil erosion, especially after the leaves of the long root weed, can ensure that the soil firmly solidly solidly.

Briefly explain the soil preservation effect of the lower plants, Roland turned to look at the busy workers on the banks of the river, "How is the bridge part now built?"

“Cement gravel pavement is being laid,” Carr reported without thinking, “it should be completed this week.”

According to the plan, the bridge on both sides of the river is made of bristling cement pile, just like the western wall, as long as the positioning and measurement work is done, the construction itself is not difficult.The bridge ramp is up to seven meters relative to the ground, and is connected to the city street through a long and slow slope with an arc, and the height difference between the embankment and the water surface is, when the iron bridge is completed, it should be able to form a net height of ten to twelve meters with the Red Water River, which is basically enough for the inland water boat sail.

The main bridge has only completed a span, and is being tested on the shore because the span is not large and the load is extremely low, and Roland is not worried about its reliability even if he does not know anything about the bridge project.In the age of eight rounds after no overload, the 30-centimeter-high I-word steel is a solid guarantee, and even if it is full of people, it is impossible to break the steel beam.Moreover, from processing to assembly welding, Anna is all arranged by Anna, and the probability of the tofu slag project is extremely low.

Similarly, its installation is very simple, until all three spans of the main bridge are prefabricated, directly by the hummingbird will be lightweighted, and then handed over to the lightning hoisting in place.

When this steel bridge, which can be used for two four-wheeled carriages, stands on the Redwater River, the north and south are truly connected as a whole.

“Even the greatest stonecler, it is hard to imagine such a magnificent bridge,” Karl lamented, looking at the vast lake, “Your Highness, does this bridge of steel have a name?”

Roland thought, "Let's call it the Red Water Bridge."(Not yet completed.Your support is my biggest motivation.)
