Chapter 67 Road Construction ([-])

After changing the road construction plan, the whole progress is much faster.Wang Luobin also did what he said. The executive committee used the personnel database to mobilize all the people who had driven tractors, construction machinery and heavy vehicles. Bai Yu was going to convert tractors into tanks and agricultural vehicles into infantry fighting vehicles. The former tank soldier, the father of the armored soldiers of the Chinese Army, was once again captured indiscriminately and was recruited into the engineering team.

Mei Wan personally went into battle, patrolling the construction site, and taught these new road builders how to use tools and soil work. It's a pity to say that most urban nerds can't even handle the shovel in their hands, so they need to shovel the soil. , Digging a ditch and raking the ground did not do a decent job.

He taught for a while, and then looked at the construction of the machinery.Although the people who drive construction machinery are not very proficient, they can still do it anyway - fortunately, the executive committee arranged for people to learn before crossing.

Fortunately, there are construction machinery, Mei Wan secretly rejoiced, otherwise it would be hard to imagine what kind of work these so-called construction team members would do.After inspecting it, I suddenly saw a person who was working well. He had been a project manager on the construction site for many years, and he could tell whether he was a novice or a proficient.The young man looks strong and solid, but his work is a bit lazy and his movements are slow.Mei Wan walked over and said:

"Good job, have you ever been to a construction site?"

"Yes, I have done a lot of work." The young man paused, "Are you Manager Mei?" Mei Wan used to be the project manager of the engineering team, so everyone called him that.

"That's right, it's me. Do you recognize me?" Mei Wan was a little surprised, he didn't know this person.

"Is it the basic ability of our wage earners to recognize the leader as soon as possible?" The young man laughed. "When you see the leader coming, you have to work hard..."

Mei Wan laughed, "What's your name?"

"Tan Ming. Everyone calls me Fat Ming." Tan Ming started working again as he spoke, "Not only did I work on construction sites, I also worked as a security guard, oil worker, online game booster, printer..."

"How did you get here as a printer?"

"I haven't made a good appearance at such a young age. Now the economic situation is bad and I am unemployed. I think I won't be able to make a name for myself anyway, so I might as well try another place."

Mei Wan turned around and returned to the tent. He was quite satisfied with the overall progress. The construction team leader Bingfeng turned into the tent and reported to him that the catering team had just delivered a 1-ton pot of drinking water, and the salt had also arrived. .

"Don't you have a helmet yet?" Mei Wan asked.

"Commissioner Wang said just now that he sent people to chop wicker this morning, and it is now being trial-manufactured."

"Okay, it's not a big problem if you don't wear it now, and there aren't many hoisting jobs." He thought for a while, "By the way, there is a man named Tan Ming in the team. He used to work on construction sites and is very familiar with the work. Arrange him to be a team leader and see how capable he is. If possible, he will be trained as a construction worker in the future."

"Okay, I'll arrange it now." Bingfeng was about to go out when Mei Wan stopped him, "In the future, you should pay more attention to this kind of thing, and train suitable people. You are a structural engineer, and you are Deputy team leader, how can I keep working as a foreman on the construction site? Isn’t it a waste.”

Bingfeng was a little confused, didn't understand what the words meant, answered a few words in random and went out.

Mei lit a cigarette late, and felt a little confused. Logically speaking, his thoughts should be on this road, but the scene from yesterday's meeting kept replaying in his mind.Unexpectedly, Zhuo Tianmin, who was always low-key, would do this to him on the spot.This is a blog post.Mei Wan thought bitterly: Zhuo Tianmin's architect and consultant qualification certificates might arouse great interest from the Executive Committee...

For a moment, he felt a sense of crisis.Originally, he was very satisfied with the team of the construction engineering team. Bingfeng, the deputy team leader, is a structural engineer, and his major is relatively biased; He looks like he's not interested in anything.

But now it's different.Although he thinks he has rich experience in the management and coordination of civil engineering, when it comes to professional standards, he is obviously no match for this man.

Just as he was thinking wildly, he reported through the walkie-talkie that the 3km subgrade work for the No. [-] lot had been completed, and now the road paving team was about to enter the site.But the pavement material has not yet been determined.With a notebook in her pocket, Mei Wan picked up a small shovel and went out of the tent to scoop up a shovel of soil along the ditch where the soil was collected, watching with her eyes and kneading with her hands.Then write something down in the notebook.Just walked meter after meter.Yan Quezhi, who was measuring the hydrological data of the Wenlan River, was baffled.

"Manager Mei, what are you looking for?"

"Look at the quality of the soil." Mei Wan casually crushed the soil in her hand, "Find the soil suitable for paving the road."

"It can't be used after digging out so much soil? Isn't the roadbed filled in the same way?"

"The soil requirements for roadbeds are simpler than those for road surfaces." Mei Wan explained that soil can be divided into clay, sand and silt soil according to particle size. Natural soil is generally a mixture of the three. Divided into nine types, each has different characteristics when used to build road surfaces.Some work well, some don't work at all, and some need modification.

"The simple road is an earthy road surface. Compared with the common hardened road surface, it has many disadvantages, such as a large amount of dust, low bearing capacity of the road surface, and the road surface will soften in rainy days, forming puddles and muddy..." He said, "So choose and process The use of soil on the road surface is a very important link, and if it is used well, such problems will be smaller and less.”

"For example, this kind of sandy soil. There is a lot of sandy soil along the river here." He shoveled up a shovel of soil. "The characteristic of this soil is that it is almost sandy, with low viscosity. It can’t be kneaded when it’s dry. The pavement paved with this soil is easy to form deep ruts when driving on sunny days and dry. In rainy days, it has weak stickiness. The advantage is that the pavement is easy to dry, and it can be used only after it is modified with a certain amount of clay. Come pave the way."

"What about this kind?" Yan Quezhi was very interested in this question. Seeing that the soil over there was different, he quickly pinched it over, "According to this, this kind of soil mixed with clay and sand is the most suitable for paving roads." .”

"It is true in theory, but it's not that simple in practice. All kinds of soil have different characteristics." Mei Wan took the soil in her hand and looked at it, then rubbed it again. It turned into thin and short soil strips, "The kind of clay you brought is fine-sandy loam. It has both clay and a lot of fine sand, so it is a bit sticky. This kind of soil is more suitable for road construction. .”

"Then this kind of soil is used?"

"The sandy loam I'm looking for," Mei Wan clapped her hands, "it's similar to this one, but the sand grains are thicker. If you use this soil to pave the road, it can maintain the compactness of the top after compaction and is not easy to loosen. There is less dust when driving, it does not stick to the wheels in rainy days, it dries quickly after rain, and it is easy to maintain to keep the road surface smooth.”

"Then how can you tell, whether the sand is fine or coarse, can you tell with this eye?" Yan Quezhi looked at the soil in his hand for a long time.

"You can see it if you look carefully." Mei Wan continued to instruct him, "The simple way to identify it is to rub it with your hands. Like the fine sandy loam you gave me, you can rub it into thin and short strips with your hands, but the sand If the quality is low, you can't rub it out."

"That's right." Yan Quezhi was completely cast-off towards him at the moment, "Professional enough!"

"Hehe," Mei Wan smiled triumphantly, "Where is it?" I thought to myself that old textbooks are indeed very powerful.

It didn't take long for Mei Wan and Yan Quezhi to discover a sandy loam land acquisition site.Of course, if such an ideal material cannot be found, Mei Wan can also modify it according to the soil conditions, but this requires an additional process and the labor intensity is much greater.

The paving work of the road surface was personally directed by Mei Wan.Because the traffic volume of the simple road is not large, there is no need to build a very thick road surface. The thickness of 15 cm and 2-3 times of compaction with a road roller are basically completed. The middle of the road surface is slightly raised to facilitate drainage.

In order to improve the strength of the pavement, the engineering team mixed some cobblestones into the pavement soil.Because suitable stones are limited, the effect cannot be compared with real gravel pavement.In other words, it is better not to drive the car in rainy weather.

"As soon as possible, as soon as possible, produce such a thing as soon as possible." Mei Wan looked at the completed section of the road, threw the cigarette butt on the ground, and stomped hard.

Just after the first shift, the courtyard of the county government was very quiet, only two watchmen on duty, carrying small white paper lanterns, walked around the courtyard every once in a while, beating shifts with wooden batons.

There are more than a dozen township braves sitting or lying in the courtyard. Normally, this important place in the government office would not allow these mud-legged savages to be so presumptuous, but the city's defenses are tight right now, and these ten township braves fought against pirates just yesterday. Yes, the yamen servants just turned a blind eye and didn't bother me anymore.

It was Huang Shoutong, the first householder of Namei Village, who brought the township bravely. He was about fifty years old.He is a large grain householder in this county. His ancestors joined the conscripts at the beginning of the country and settled in Lingao. His ancestors changed their nationality through a few scholars, and the clan prospered.Generosity and righteousness are very prestigious in the village and clan.

Lingao has always been harassed by pirates, and the local situation is not peaceful.Since the Jiajing year to defend against Japanese pirates, his family's ancestors have built earthen villages in Namei Village and practiced bravery.It is the famous "hard court" of Lingao.In his generation, headed by Namei Village, there are about five or six hundred township braves in the neighboring six villages.In recent years, the place has been turbulent. Every time Huang Shoutong sent troops to suppress bandits or defend the county, Huang Shoutong took Xiangyong to participate. He contributed a lot and was highly praised by Wu Mingjin.

Huang Shoutong is white, but one of his sons is a scholar who is studying in the county school. When he invited the gentry to the meeting this time, he arranged defenses in each village by himself, and only let the son from the county school attend, and sent more than a dozen more Xiangyong brought a cart of grain, rice and vegetables into the city to help defend.Now that the old man brought someone to visit suddenly, Wu Mingjin was surprised and delighted at the same time. After the host and guest sat down in the flower hall, they exchanged greetings. Wu Mingjin saw that the old man's net scarf was changed to white, and his eyes were red.He was very surprised, he knew that Huang Dahu's parents had passed away, could it be that his old wife also died of illness?

Seeing the magistrate's face full of surprise, Huang Shoutong told him: One of his sons was killed yesterday when he attacked the pirates.
