Accompanied by Wang Manyin and Liu Xiangyang, Xie Shouzheng spent almost three days turning around the ditches and ravines around the village and drawing a simple topographic map at the same time.

This person usually chats cautiously, and when he talks about professional work, he seems to be a different person, and he seems to be full of energy and talking.

Especially after Wang Manyin mentioned Li Yizhi, Xie Shouzheng's words were full of admiration. It is bluntly said that the "Guanzhong Bahui Canal" designed by him has benefited millions of people and has made immeasurable merits.

Liu Xiangyang heard about this person for the first time, and after knowing his deeds, he was also amazed.

In later generations, few people from other provinces knew about Li Yizhi, let alone his status in the hearts of the people of the land of Sanqin.

In a word, this is a "god" who was worshiped by a temple. Even in these turbulent times, its incense has never stopped.

It was also from Xie Gong's mouth that Wang Manyin deeply understood that it was far more complicated than imagined to successfully build a dam on the loose Loess Plateau.

From site selection to construction materials, a lot of drawing and calculation are involved. For example, the amount of sediment in the year, the maximum rainfall in the year, the filter layer, the spillway......

If there is a problem with the design, a rainstorm can cost countless people months, if not years, of their efforts.

In recent years, the Loess Plateau has been vigorously promoting silt dams. Many villages built their own, and the design of the dam was too reasonable. It basically belongs to "building and rushing, washing and destroying, and destroying and rebuilding".

Xie Shouzheng and his team have done an investigation, and in the past three years, due to heavy summer rains, more than 3,000 dams have been damaged in Yuanxi County.

Among them, most of the dam body failed, and most of the sediment in the dam site was washed away, accounting for 34%, and the rest was part of the dam body burst, and the spillway was damaged.

During this period, Wang Manyin revealed the idea of digging a pond to store water and raise fish.

Xie Shouzheng didn't find it strange that the silt dam itself has the effect of storing water and raising fish, as long as it is slightly changed when the flood channel is designed.

When the design plan came out, they immediately reported it to Wang Lianshun.

Wang Lianshun did not delay, and recruited a few capable people from the second team as usual to hold a small meeting in the evening to study.

Wang Manyin and Liu Xiangyang are naturally among them.

It's just that I didn't expect that even Zhao Jianhai and Wang Manchu came.

It can be seen that the village also attaches great importance to this matter.

Next, Xie Shouzheng hung the drawings on the kiln wall and began to briefly introduce his design drawings.

The specific location of the silt dam he designed is in the east mountain ridge on the edge of the village. The geographical environment of that area is better, there is a long cliff ditch in the shape of a gourd mouth, and the slope is relatively gentle, close to the Dongla River.

To build a dam at the mouth of the ditch, the amount of soil and rock should not be very large.

Of course, two spillways and sluices were also designed.

In the event of a sudden rainstorm, as long as the sluice gate is opened in time to discharge the flood, the safety of the dam can be ensured to the greatest extent.

After the successful completion of the project, it will be able to increase the land by about ten acres within a year, and the area will increase in the later stage.

Hearing that only ten acres of land were added, Zhao Jianhai was disappointed, and immediately interrupted: "Xie Gong, I feel that your design plan is too conservative!" Ten acres of land, what is the difference between not increasing? ”

"There are already a lot, silt dams are a long-term process, and they should be mainly small, small and many in groups, and a combination of large, medium and small. If you want to increase the area of the river, you can continue to build the second and third dams on the tributaries in the later stage to form a stepped drop. ”

"It's still too slow! I have an idea, you see if it's okay," Zhao Jianhai said, and stood in front of the drawing.

He stuck his left hand on his waist, and his right hand gestured on the drawing, making a powerful voice: "We will be in place at one time and intercept the entire Dongshan Pass." According to your calculations, you can add at least 100 acres of Sichuan land. By the way, a neutral reservoir can also be built to facilitate the irrigation of farmland in the later stage. Kill more than one stone! ”

In Zhao Jianhai's view, since it is not possible to cut off the Dongla River, it will be changed to cut off the Dongshan Pass!

Do it vigorously!

"This, this ......" Xie Shouzheng was stunned in place, not knowing how to answer.

"Xie Gong, what do you have to say." Wang Manchu urged.

Xie Shouzheng hesitated for a moment, and finally decided to tell the truth.

"Director Zhao, the silt dam also has requirements for terrain selection, small mouth, large belly, gentle slope, and more silt, which can save time, labor and effort, and can see specific benefits within one to two years. If the entire Dongshan Pass is intercepted, the amount of work will be very large, and it is not at all possible that the hundreds of laborers of the Jar Village can complete it. And it will take a long time......"

"We are not afraid of a large amount of work, as long as we can add hundreds of acres of good land to Jarzi Village, we are confident that we will overcome difficulties." After speaking, Zhao Jianhai waved his hand at several people opposite, showing great momentum.

Seeing that Xie Shouzheng was going to continue to explain, Wang Manyin hurriedly stopped the conversation: "Xie Gong, if you follow Director Zhao's assumption, how much labor will you need to calculate?" ”

"According to the calculation of the amount of earth and rock, it will take at least 20,000 people and take half a year to complete. Of course, if there is a large construction machinery, the speed will be accelerated a lot! In addition, since a small reservoir is being built, the construction materials can no longer use earthwork, but stone cement mortar...... If there is a shortage of stones, prefabricated reinforced concrete blocks can also be used. ”

"Director Zhao, just do what you envisioned. You will go to the commune tomorrow to contact you, let the top take the lead, and call on other villages to come to our canzi village to volunteer as migrant workers. In addition, let the commune approve some cement mortar...... This thing is done, all the members of Jar Village will write you a thank you letter! Wang Manchu said with a smile on his face.

"That's right, Director Zhao, it's really done, our second team will set up an archway for you!" Wang Lianshun hurriedly answered.

"Director Zhao, I like a good man like you who dares to think and dare to do!"

Wang Yanqiang also praised again and again.

Wang Manyin and Liu Xiangyang glanced at each other and forced a smile.

If Director Zhao can really do such a thing, they will not object.

Not to mention adding hundreds of acres, even if it adds dozens of acres of silt land to Jar Village, it is definitely a good thing.

Wang Lianshun and others may have the same idea and send their members to do volunteer work, but of course they are unwilling.

But it is very happy to have other village members come to volunteer for Jar Village.

"I'll try," Zhao Jianhai no longer had the momentum just now, and replied a little weakly.

He came to Jarzi Village as a resident cadre, and he always wanted to make a name for himself as soon as possible and return to work in the commune as soon as possible, so he put forward various dazzling ideas.

In Zhao's view, he only provided ideas, and the specific operation should be completed by the village.

Now let him go to the commune to run the process...... Whether it is to dispatch 20,000 migrant workers or cement mortar and steel bars, I am afraid it is not so easy.

Especially cement mortar and rebar, these need indicators. And even if the target is obtained, the village of the jar has no money to buy it, and it can't let the commune pay for it.

But looking at everyone's expectant eyes, he couldn't refuse at all. After all, after saying his own words, he could only agree to come down first.

Originally, Xie Shouzheng had to continue to explain, but now he can only pause. After all, he was only invited by others to do technical guidance, and it was the people of Jar Village who really made the decision.

You can do what you need to say and do with your conscience, and you don't have to force the result.

After Wang Manchu said a few words, the meeting ended hastily.

When sending Xie Shouzheng away, Wang Lianshun took the initiative to comfort: "Xie Gong, there are many good things, and you need to wait for a few more days......

The meaning of his words was obvious, and he was not optimistic that Director Zhao would go to the commune to find support.

"I know, I know," Xie Shouzheng could only nod.
