Su Wang's family was forcibly escorted to the hall, and then the light of the fire fold saw the people in the room, and was shocked: "Father, mother, and the third child, you have also been arrested." ”

Grandma Su smiled awkwardly: "I'll come here before you, but we weren't arrested." ”

"Big brother?" Su Lao Er asked with some uncertainty.

Boss Su snorted coldly: "It turns out that you still know me as a big brother, and I thought you had seen a ghost." ”

Su Lao Er saw that the old couple kept squeezing his eyebrows at him, and suddenly understood that the person in front of him was undoubtedly the eldest brother.

"Big brother said and laughed, just now the big brother suddenly came out, who do I think, you also know that I am afraid of strange things."

...

Boss Su was speechless, and he roughly knew what the old couple and the second room had in mind these days.

This is also to blame him, he has been busy interrogating the Niu family a few days ago, thinking that the Li family or Su Baiya would explain to the old couple and the people in the second room, so he ignored them.

If you don't make things clear, maybe there will be some trouble in the future, so I simply explained what happened at the banquet that day.

The old couple and the second room finally solved the doubts in their hearts, and they were embarrassed and surprised in their hearts, and the courage of the Niu family was too great.

I don't know why I learned about it, and when I looked at the good and decent Boss Su, I felt a sense of loss in my heart.

Through these things, Boss Su is now very disappointed in this family, and after explaining the events of the day, he ordered Zhang Lang and Li Huan to return to the yamen with the body of the masked man outside the hall.

After taking care of everything, it was late at night when I got home.

Su Baiya learned about the Su family's troublesome oolong from Boss Su on the second day, and she couldn't laugh or cry.

If you continue to take it to the company for two days, or if Boss Su returns to the village two days late, you don't know how big the trouble will be.

Fortunately, events did not turn out more than expected.

...

The magistrate of the county will not hesitate to agree to Su Baiya's request, because he was a clever classmate at the beginning, and he had experience in water control, and he was in the boundary of Qinghuai County.

However, this person is not a material for reading, and he has repeatedly failed to do so, and he is still persisting in his forties now.

Su Baiya informed He Gaoming of her thoughts, and went to investigate the actual situation together.

The river that passes through the two villages is called Baigou River, which is about five zhang.

I asked the old people in the village and learned that the Baigou River will not dry up all year round, and the lowest water level in winter is only about 30% or even less, and it will rise one after another after spring, and the highest water level will be about 90%.

The depth of the river is about three zhang, which is about nine meters in later generations.

In the decades that the old man has lived in the village, there has not been a breach of the embankment, and the water level of the river is quite stable.

After asking the old man, Su Baiya took He Gaoming to the bank of the Baigou River, and carefully inspected it for nearly a day along the way before it ended.

Su Baiya can see that He Gaoming is a meticulous person, not to complete the process of walking around the county's instructions, and having him help repair the dam and divert water into the canal should be half the success.

When he returned to Qulan Town, he invited He Gaoming to Fuyun Building for dinner together, and discussed things while eating.

He Gaoming's conclusion was similar to what he had predicted, because the overall terrain of the two villages was low, so the construction of ditches was not a big problem, and the villages could be flooded if they were not properly handled during the flood season.

Ho's advice was to build a dam on the river, and close it during the flood season or when the river rises, so that as long as the dam is maintained, there will be no flooding.

Su Baiya's thoughts are the same, but she really has no experience in building a dam, so she shamelessly asked: "In Uncle He's opinion, how to build a dam." ”

He Gaoming is a person who loves wine, he didn't eat a few bites of food, he had already drunk half a pot of wine, and said with a red face: "The purpose of Mr. Su's dam is to divert water for irrigation, and it will be farmed around March at the earliest, right?" ”

Su Baiya nodded: "That's right." ”

"That's right," He Gaoming said, chewing on two peanuts, "now is the time of the year when the water level is lowest, and it is a good time to repair the dam, and the excavation of the riverbank only needs to be above the current water level, which saves a lot of things." ”

Su Baiya asked, "What do you say?" ”

He Gaoming snorted and said: "The purpose of this dam repair is to intercept the water source, if you don't stop the water first, how to repair it, Shanjin is relatively short of water, a few years ago, the government decided to divert the water of the Jiuli River over, just the interception before the dam repair took a lot of effort." ”

"Mr. Su's current dam repair is at the right time, saving the process of throttling."

He was very interested in water conservancy matters, so he paid special attention to them.

"So how exactly do you build the dam?"

Su Baiya asked again, and if it was true, many people drank a little more and talked more.

At the same time, I was secretly glad that the time to plant rice was just right, and if it was summer, it might have to be postponed for another half a year.

He Gaoming shook the wine pot that had bottomed out: "Now in winter, there is no need to worry about sudden floods, Mr. Su can send someone to dig the river bank first, the dam repair is currently the most common, the easiest way is to use a wooden pile as a foundation, and then use a stone to intercept, and use lime, glutinous rice, tung oil and so on to hook the joints." ”

"And Mr. Su's dam needs to release water for irrigation, according to the old people we visited, the water level is about 70%, we only need to dig to 60% of the position, and wait for the water to be released enough to close the dam."

Su Baiya asked urgently: "How to close?" ”

He Gaoming slapped the wine gap again and shook the already empty wine jug.

Su Baiya was helpless and ordered the work to serve a pot of good Fenjiu.

He Gaoming continued: "There is a width of about five feet to release water, and then expand about five feet on both sides of the water outlet, and use long stones to build it, leaving a width of two feet in the middle of the long stone. ”

Su Baiya asked, "Why is that?" ”

He Gaoming took a sip of the wine in the cup, and said slowly: "Mr. Su asked the carpenter to make a dam gate about 15 feet high and 7 feet wide with water-resistant wood, and put it into the reserved width of two feet to stop the water. ”

"Then build a row of walls on both sides of the dam that are higher than the dam gates, so that the height can be raised with ropes, and when the water needs to be released, the dam gates should be raised and lowered vice versa."

Su Baiya felt that this method was feasible, and the principle was somewhat similar to the common gate bridge in later generations.

However, the fineness of today's materials is far from being compared with later generations, and although the use of dam doors can not completely cut off the flow of water, if you add a few more dam gates, the waterproof effect is almost gone.

At the same time, a catchment pond can be dug near the village, and the water seeping out of the gap in the dam gate can flow into the catchment tank without affecting the fields.

At the same time, it can also shorten the distance for villagers to fetch water, which has many benefits.
