After changing the road construction jihua, the whole progress is much faster. Wang Luobin also did what he said, and the executive committee mobilized all those who had driven tractors, construction machinery, and heavy vehicles through the personnel database, and Bai Yu, a former tank soldier who was ready to convert tractors into tanks and agricultural vehicles into infantry fighting vehicles, and became the father of the armored troops of the crossing army, was once again arrested indiscriminately and was enriched into the engineering team.

Mei Wan personally went into battle, patrolling the construction site, and by the way, taught these new road builders some tools and earthwork - pitiful, most of the urban otaku did not even have a shovel in their hands, and asked them to shovel the soil, dig a ditch, and rake the ground, but none of them did 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 skilled, they can still do it - fortunately, the former executive committee arranged for someone to study.

Fortunately, there are construction machinery, Mei Wan secretly rejoiced, otherwise it is difficult to imagine what this group of so-called construction team members will do. After inspecting it, I suddenly saw a person who was working in a decent way, he had been a project manager on the construction site for many years, and he knew at a glance whether he was new or familiar. The young man looks strong and solid, but he is a little lazy and slow. Mei Wan walked over and said:

"Well done, have you ever been on the construction site?"

"Yes, I've done a lot of work." The young man paused, "You're Manager Mei, right?" "Mei Wan used to be the project manager of the engineering team, so everyone called it that.

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

"Recognize the leader as soon as possible is the basic ability of our workers," the young man laughed, "When I see the leader coming, we have to work hard quickly......

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

"Tan Ming. Everyone calls me Fat. Tan Ming said and got back to work, "Not only have I worked on construction sites, but I have also worked as a security guard, an oil worker, an online game booster, a printer, ......."

"How did you get here as a printer?"

"It's not a good old age, and now the economic situation is not good, and I am unemployed. I don't think I'm going to be famous anyway, so let's try it in a different 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 food team had just sent a 1 ton of drinking water jug, and the salt had also been allocated.

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

"Commissioner Wang just said that he had sent someone to cut wicker in the morning, and now he is trying to produce it."

"Okay, it's not a big problem if you don't wear it now, and there is not much hoisting work." He thought for a while, "By the way, there is a man named Tan Ming in the team, who has worked on a construction site in the past and is very familiar with the work, you first arrange for him to be a team leader and see how capable he is." After he succeeded, he was trained to be a construction worker. ”

"Haode, I'll arrange it." Bingfeng was about to go out, but Mei Wan stopped him, "In the future, you have to watch more of this kind of thing, and if there is a suitable person, you will cultivate it." You are a structural engineer and a deputy team leader, how can you always be a foreman on the construction site? Isn't it wasted? ”

Bingfeng was a little confused, didn't understand what he meant, and went out after a few random answers.

Mei lit a cigarette late, and his mind was a little confused, and it stands to reason that his mind should be on this road, but the scene from yesterday's meeting kept coming back to his mind. Unexpectedly, Zhuo Tianmin, a person who has always been low-key, actually gave him this hand on the spot. This is in the Bo position. Mei Wan thought a little bitterly: Zhuo Tianmin's qualification certificate as an architect and consultant may have aroused 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, and Bingfeng, the deputy team leader, was a structural engineer with a relatively partial major; Xiaoyan is a miscellaneous family, broad but not refined; Although Li Xiaolu has a very high level of business, she is a woman, and she looks like she is not interested in anything.

But now it's different. Although he admits he has extensive experience in the management and coordination of civil engineering, he is clearly no match for this man when it comes to professionalism.

Just thinking about it, it was reported on the walkie-talkie that the 3-kilometer roadbed work of the No. 1 section had been completed, and now the road paving team was about to enter the site. However, the pavement material has not yet been determined. Mei Wan put on a notebook, picked up a small shovel, got out of the tent and kept shoveling a shovel of soil along the ditch where the soil was taken, looking at it with her eyes and kneading it with her hands. Then I wrote something down in a notebook. It just walked meter after meter. It is inexplicable to see the swallow finch that is measuring the hydrological data of the Wenlan River.

"Manager Mei, what are you touching?"

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

"Digging up so much soil can't be used? Isn't the roadbed filled in this way? ”

"The requirements for subgrade soil are simpler than road surfaces." Mei Wan explained that soil can be divided into clay, sand and silt according to the particle size, and the soil in nature is generally a mixture of the three, which can be subdivided into nine types according to their different contents, and each has different characteristics for building roads. Some are very suitable, some are completely unusable, and some need to be modified.

"Simple roads are dirt pavement, compared with common hardened pavement, there are many disadvantages, such as a large amount of dust, small pavement bearing capacity, rainy days the pavement will soften, the formation of puddles and muddy ......," he said, "so the selection and processing of pavement soil is a very important link, good use, this kind of problem will be smaller, less." ”

"For example, this kind of sandy soil, there is a lot of sand along the river here." As he spoke, he scooped up a shovel of soil, "The characteristics of this soil are that it is almost all sand, and it is not sticky, and it is loose and not formed when it is dry, and it cannot be pinched and molded when it is wet." The paved road with this soil is prone to deep ruts when driving on dry sunny days. On rainy days, there is a faint stickiness. The advantage is that the pavement is easy to dry, and it can only be used to pave the pavement after a certain amount of clay modification is added. ”

"What about this?" Yan Que Zhi was very interested in this question, and when he saw that the soil over there was different, he quickly pinched it a little, "According to this theory, this kind of soil mixed with clay and sand is the most suitable for paving." ”

"In theory, that's true, but in practice it's not that simple. Various soils with a little more and a little less have different characteristics. Mei Wan said as she took the soil in her hand and looked at it, rubbed it again, and the soil turned into thin and short strips of soil, "The kind of soil you brought is a fine sandy mound, which has clay and contains more fine sand, so it is a little sticky, and this kind of soil is more suitable for building roads." ”

"That's what you use?"

"The sandy mounds I'm looking for," Mei Wan clapped her hands, "it's similar to this one, but the sand grains are coarser." If you use this soil to pave the road, it can maintain the compactness of a top after compaction, it 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 the smoothness of the road surface. ”

"Then how can you tell it, whether the sand is fine or coarse, can you see it with this eye?" The bird looked at the dirt in his hand for a long time.

"If you look closely, you can see it." Mei Wan continued to instruct him, "The simple way to identify is to rub it by hand, like the fine sandy ridge you gave me, you can use your hand to knead it into thin and short strips of soil, but the sandy ridge can't be rubbed out. ”

"That's right." Yan Quezhi was almost thrown into him at this moment, "Professional enough!" ”

"Hehe," Mei Wan smirked, "where, where." "I thought to myself, the old textbooks are really powerful.

It didn't take long for Mei Wan and Yan Que Zhi to discover a land acquisition site for a sandy mound. Of course, if you can't find such an ideal material, Meiwan can also be modified according to soil conditions, but in this case, there is one more process and the labor intensity is much larger.

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

In order to improve the strength of the road surface, the engineering team mixed a part of the pebbles into the road surface soil. Because the suitable stone is limited, the effect is not very comparable to that of a real gravel pavement. In other words, it's best not to drive the car on rainy days.

"As soon as possible, as soon as possible, as soon as this thing happens." Mei Wan looked at the finished section, threw the cigarette butt on the ground, and stepped on it hard.

Just after the first watch, the courtyard of the county government seemed very quiet, only two soap officers carrying small white paper lanterns, walking around the courtyard every once in a while, using wooden poles to make a watch.

There are more than a dozen villagers sitting or lying in the courtyard, if it is usual, this official office cannot tolerate this group of mud-legged barbarians to be so presumptuous, but at present, the city defense is tight, and these more than ten villagers have just fought with the pirates yesterday, and the officials will not bother with a closed eye.

Huang Shoutong, the first household of Namei Village, was around 50 years old, burly, energetic, with a short beard that was a little gray, broad eyebrows and a wide forehead, and his eyes were open and closed like lightning. He is a big grain household in this county, his ancestors were recruited at the beginning of the country, settled in Lingao, and his ancestors changed their nationality after a few shows, and the clan developed. He is generous and righteous, and he is very prestigious in the township and clan.

Lingao has always been harassed by pirates, and the local area is not peaceful. Since the Jiajing year to defend against the Japanese invaders, his ancestors have built a soil village in Namei Village to practice village bravery. It is the famous "hard ground" of Lingao. In his generation, headed by Nami Village, close to the six villages and townships, five or six hundred villagers can be dispatched at any time. In recent years, the place was not quiet, and every time he sent troops to suppress bandits or defend the county seat, Huang Shoutong took the villagers to participate, and contributed a lot, and was very commended by Wu Mingjin.

Huang Shoutong is a white body, but there is a son who is Xiucai who is studying in the county school, this time when he invited the gentry to the meeting, he himself arranged defense in each village, only let the son of the county school to participate, and sent more than ten village warriors to bring a cart of grain, rice, vegetables and vegetables into the city to assist in the defense. Now the old man suddenly brought someone to visit, Wu Mingjin was surprised again, and felt happy, after the guest and host sat down in the flower hall, a little greeting, Wu Mingjin saw that the old man's net towel was changed to white, and his eyes were red. He was surprised, he knew that Huang Dahu's parents had passed away, could it be that his old wife had also passed away?

Seeing that Zhixian was full of surprise, Huang Shoutong told him that one of his sons had died in attack on the pirates yesterday.
