The survey camp rested in Fuyuan Village for a day, and the next day set out to the mountains to survey the terrain of the entire Luoshan area.

The location of the dam of the reservoir is not complicated, it is nothing more than choosing a pass with a relatively stable foundation on the main stream of the water-rich stream. Build a dam with concrete, install a sluice, and you'll be all right. However, the rest of the reservoir still needs to be carefully surveyed, and it is necessary to pay attention to whether there are other gaps in the entire reservoir area, whether there are caves and other terrain that may cause water leakage in the places below the water level.

The survey was a very large task, requiring the determination of slopes and elevation differences throughout the valley in order to calculate which areas would be inundated in the future and where secondary dams would need to be built to hold back the water. Su Hao brought the entire survey camp to Luoshan to do these jobs. Of course, the soldiers of the survey battalion will also be comprehensively trained in this work, so that they can truly master the skills of field surveying and mapping.

Before leaving, Su Hao invited several old people in the village to carefully introduce the whole picture of Luoshan, and drew a sketch according to what they said. Subsequently, according to the sketch, the Luoshan area was cut into more than a dozen parts, and each copy was assigned to a survey team. Each survey team consisted of a student from the academy and seven or eight soldiers from the survey battalion, equipped with a full set of surveying and mapping instruments, benchmarks, tents, and other items.

The survey teams assembled in front of the camp and prepared to set off. Everyone, whether they were a soldier or a soldier, had a look of excitement on their faces, feeling that they were about to do something very great. Regarding the significance of this surveying and mapping, Su Hao has already told everyone, thinking that the design of a large reservoir with a water storage capacity of one million cubic meters will be born from his own hands, everyone has a sense of pride.

"Su Baihu, if the reservoir is repaired in the future, when the monument is erected, will we write our names?" Xiong Minyang couldn't wait to ask Su Hao, who was inspecting the preparations of each group.

Su Hao patted the backpack on Xiong Min's shoulder and said with a smile: "This is a good proposal, I'll go back and report to Han Zhixian." However, you'll have to do it for me first. If one line can't be measured, I'll ask the teacher to tear up your drawings and start all over again. ”

When Su Hao said about teaching, he meant that the academy students in each group had a higher level of education. Exposure to mapping is also much earlier. I have always been in a teaching position in the survey camp. In the past teaching practice, if the drawing of a small flag is not good, the teacher will directly tear the picture out.

"The third child of the Xiong family, test it well. If you tear up your test map, don't cry! A soldier surnamed Liu shouted loudly at Xiong Minyang. Xiong Minyang is the best learned in the surveying and mapping class among these soldiers, and everyone is full of envy, jealousy and hatred for him, so when it comes to this actual battle. I can't help but belittle him.

Xiong Minyang made a look of looking up to the sky and laughing, smirked twice, and then replied: "Lao Liu, you still care about yourself." I always ask me to help you when I train, but now everyone is in a group, and no one is helping you, so don't come back with a few blank papers. ”

The old Liu said angrily: "Xiong Laosan, you speak more reliably, what do you mean by letting you help us." You've helped us once, and you've been talking about it for two months. Let me tell you, there are wild boars in this mountain, you little bones, don't let the wild boar bite you. ”

Heard someone threatening his brother. The second child of the Xiong family didn't do it, Xiong Minfan stood up, patted his chest and said, "The surname is Liu, what do you say." With my second bear here, what wild boar dares to go wild? ”

"Alright, alright. Don't make any noise! Deng Kui appeared, and he shouted with a tiger face: "Before you go on the expedition, what is the loud noise? Have you checked the equipment of each flag? I will re-check it in a while, and if the inspection is unqualified, from the small flag below, each person will have five military sticks! ”

Seeing Deng Kui appear, everyone quickly shut up and began to seriously check their equipment. Fearing the appearance of wild beasts and villains in the mountains, each group carried a few spears and knives in addition to surveying and mapping equipment, which did look a bit like going on an expedition.

In the past few months, in addition to learning surveying and mapping knowledge, the soldiers of the survey battalion have also undergone strict military training, and the soldiers have already possessed a certain combat ability, which can be regarded as an army with acceptable combat effectiveness.

"Su Baihu, the sons and daughters are ready, are you ready to go on the expedition?"

After confirming that each group was ready to stop, Hao Tong and Deng Kui came to Su Hao side by side, gave him a military salute, and then solemnly asked him for instructions.

After several months of military training, Su Hao also began to gradually adapt to the rules of the army. Hao Tong and Deng Kui are both from the border army, and the discipline of the border army is obviously better than that of the guards in the mainland, and when they do anything, they both follow the standards of wartime, which makes Su Hao easily dare not relax too much in front of them.

"Let's go!" Su Hao replied, "Pay attention to safety, send the surveying and mapping data back in time, and I will arrange for the embroidery lady to embroider the drawings here." ”

"Order!" Hao Tong and Deng Kui replied loudly. Then, they turned to the soldiers and issued one order after another, and the soldiers lined up as they usually trained, and under the guidance of their guides, they walked mightily towards the mountains.

The team left, and only Han Qian and other women remained in Fuyuan Village, as well as a few soldiers who stayed to guard the camp. In addition, it was Su Hao, Ma Yu and Zhao Luo, the rich man of Xuanfeng Township who had just rushed over. Of course, Zhao Luo also brought his own slaves, so that's another matter.

"Su Baihu, Brother Duwen, you are too uninteresting, didn't you say that you want to call Brother Yu to come with you? If I hadn't heard from Xu Yashi, I wouldn't have known that you had already set off. Zhao Luo muttered.

At this point, they walked upstream along the Fushui River valley to find a suitable site for the dam. The task left by Su Hao and Ma Yu was to determine the dam site, and as for Zhao Luo, he followed them to watch the excitement.

Hearing Zhao Luo's complaint, Su Hao smiled and said, "Mr. Fengling, I'm really sorry, my junior brother is so busy this time that he forgot what he promised to Mr. Fengling." However, then again, even if the little brother forgot to inform you, aren't you already here? ”

Zhao Luo didn't really want to ask the teacher to ask for guilt, he said: "Su Baihu is really a talented person, and it is inevitable that he will be busy. I have also been to see the coal kiln you opened in my mountains, and it is really a daily profit, and I regret that I agreed to let you mine coal. ”

Ma Yu said: "Mr. Fengling, people can't stand without faith, and you can't easily regret what you promised." If you don't have a brother to survey the coal deposit under your mountain field, I'm afraid you won't be able to find it if you change to another coal master. Brother Chang didn't take advantage of you. ”

"Yes, yes." Zhao Luo said with a big grin, "When did I say that I took advantage of me?" Instead, provide me with lime and what kind of phosphate fertilizer, and my husband Zhu has already raised hundreds of short-term workers, and is ready to open up 50 hectares of fields before the spring of next year. Speaking of which, I took advantage of the change. Let's just say that, Mr. Zhu is such a bitter and mean person, when it comes to changing it, it is full of praise, think about it, how much merit it is to change it. ”

"Mr. Fengling, let's not talk about Mr. Zhu's good?" Su Hao couldn't cry or laugh, thinking that the old man Zhu Xi had worked hard for the old Zhao family, but it ended up in Zhao Luo's mouth, and he actually became a bitter and mean person.

"Haha, it's Zhao who lost his words, sin, sin." Zhao Luo changed his mistake and said in a loud voice.

The three of them chatted about various things of interest and walked all the way. Ma Yu constantly marked the terrain along the way, and Su Hao explained to him the essentials of the dam site selection. As we walked, a narrow pass appeared in front of us, flanked by high mountains, and beyond the pass was a wide river valley. Su Hao nodded and said, "Brother Duwen, this is the dam site we are looking for." ”

"Really?" Ma Yu's eyes lit up, he looked up at this pass, and couldn't help but raise his hand and gesture: "Brother Change, do you mean that we will build a 10-zhang high dam in this place and block the rich water inside?" ”

"Exactly." Su Hao said, "You see, this pass is only more than 100 zhang wide, and the amount of work to build a dam here is the smallest. The mountains on both sides are made of granite, and the underground is also granite, which is extremely solid, which is the most suitable reservoir dam site. ”

Zhao Luo asked: "Change, do you mean that as long as you find some people and strong, pick up soil to plug this pass, you can store water and become a reservoir?" ”

"Simply put, yes." Su Hao said with a smile. In fact, the repair of reservoirs is really not a complicated matter, in later generations of China, there was a period of large-scale farmland water conservancy, at that time the construction of reservoirs in various places was done by migrant workers on their shoulders. As long as there is correct theoretical guidance and scientific site selection, even if there is no mechanized equipment, a reservoir can also be built with primitive tools.

"It's so easy, why hasn't anyone done it before?" Zhao Luo was surprised.

Su Hao thought for a while and said, "There may be a problem with materials." To build a reservoir, it is not enough to have a dam, but also a sluice gate so that water can be released at any time. If earth-rock dams are used, the sluice gates will be difficult to repair. This is not the same as the sluice gates on the river embankment, where the water level of the ordinary river embankment is only one or two zhang, and the water pressure is limited. We want to build a 10-zhang high dam here, and we must use concrete to build a sluice, and concrete needs to be matched with cement. ”

"I see." Zhao Luo slapped his thigh, "I have long heard that in addition to burning lime, the edge of your coal kiln is also burning something called cement, which was originally prepared for this matter." There are so many good things in the stomach. ”
