Discuss things? Could it be a matter of digging a ditch to solve the flood?

Banxia thought while washing: But why did Master Tongzhi Xu also come?

Banxia's mind couldn't help but recall the chubby middle-aged man with a little gray hair on his sideburns, a pale face, and a courteous tone when he first met the pier.

Did he come over on his own initiative, or was he invited by Su Zhiyuan?

Banxia is also a heartless person, and if he can't figure it out, he doesn't want to, so he just turned around and asked him, but he still can't guess it.

But just wait until it's time for lunch.

"Haven't they come out yet?" Banxia asked.

"There's no movement in the study, presumably ......" Ruyi's words were not finished.

Mama Su came in with the curtain: "Madam, the word is spread over there, there is no need to wait for him for lunch, Madame wants to eat first?" ”

"Let's pass the meal," Banxia said lightly, "Did the adults deliver the food over there?" ”

Mama Su said: "Su Yi has already sent it over, waiting outside the study." ”

"Hmm."

A light rain began to fall in the sky, and the whole world was shrouded in a white mist.

Xuan Li took his sister's hand and wanted his sister to play with him, but he was yelled back by his sister...

Xuan Li didn't dare to disturb his sister's nap, and took small steps to play with his mother.

"Mother." rushed into Banxia's arms like a small cannonball.

Banxia picked him up and put him on his lap, and Xuan Li pointed out excitedly: "Go out." ”

"It's raining outside, and you're going to get wet."

Xuan Li didn't listen to the second half of the sentence at all, just listening to the word rain, his eyes lit up.

Banxia slapped the bear child on the buttocks: "If it's big for a while, you'll catch a cold, and you have to drink very bitter medicine." ”

Xuan Li pursed his mouth and was aggrieved: "Looking for Daddy." ”

Banxia still doesn't know what this bear kid is thinking! Don't look at him small, ghostly and ghostly, every time Su Zhiyuan and Banxia are together, he will always think of supporting Xuanli, yes, as long as Xuanli's request is not excessive, Su Zhiyuan will generally respond.

Banxia raised her eyebrows, and she would start to move the rescuers!

"Daddy is busy today."

When Xuan Li heard this, the golden beans in his eyes instantly dripped down.

Banxia ignored him, put him on the soft couch, and let him cry.

Mama Su was a little soft-hearted, and couldn't help but intercede for him: "Madam, the young master is still young, why don't you take the little master to the hall to play for a while?" ”

"Mama don't pay attention to him, he is just crying and bluffing, you just need to ignore him, it'll be fine for a while."

Mama Su wanted to say something, but she saw Xuan Li wiping her tears alone and playing on the soft couch by herself.

Mama Su shut up.

Banxia yawned, just about to finish coaxing the bear child and rest for a while.

Ruyi came in: "Master, as soon as Su comes, the adults and guests have not eaten yet." ”

Banxia frowned, could it be that the discussion was too intense!

At this time, the three people in the study were all in excitement.

There were a few drawings and a map of Qianzhou on the desk.

Tongzhi Lord Xu trembled his hands and looked at a picture that had just been drawn: "Blue is better than blue, not bad, but the future is terrifying." ”

The master is a native of Qianzhou, he has lived in Qianzhou since he was a child, among the three people, he is the most familiar with the situation in Qianzhou: "Digging a ditch is good and helps to drain water, but Qianzhou is at the confluence of the three seas, if it encounters a rainy season or special circumstances, the sea rises and flows back to the city, what should I do?" ”

Su Zhiyuan frowned: "This is a big problem, thanks to the master, otherwise we would all ignore it." ”

The master said: "The adults are all for the people of Qianzhou, and it is their blessing that Qianzhou has such good officials as adults who are dedicated to the people." ”

"Knock knock" Su Yi knocked on the door: "My lord, Mrs. is here to deliver food." ”

Su Zhiyuan moved his numb feet, got up and opened the door: "Why did the lady come in person?" ”

Banxia glanced at him: "Eat quickly, no matter what, the body is the most important." ”

Su Zhiyuan took the lunch box in Banxia's hand with one hand, and wiped the rain from the corner of her forehead with his right hand.

Tongzhi Lord Xu nodded in greeting, and Master Xu got up: "Madam." ”

"The two of you have worked hard, and the kitchen has made some dishes, and I don't know if it suits the tastes of the two." Banxia Road.

"Madame is gracious."

The rain outside the house was heavy, and the trumpets smashed on the ground, and the leaves outside the courtyard were blown crooked by the wind.

Su Zhiyuan looked at the heavy rain outside and said worriedly: "The lady will sit here for a while, and then come back when the rain is light." ”

Banxia smiled and apologized to Tongzhi and Master, but the two said they didn't care.

After Su Zhiyuan and the three of them had a simple meal, they began to ponder Fushougou again.

Fushougou is the name of the water supply and drainage ditch for three people.

According to the topographical characteristics of the south and north of Qianzhou, Su Zhiyuan suggested that two drainage ditches should be established by using zonal drainage.

The second ditch is connected with the three ponds in the city (Phoenix Pond, Goldfish Pond, Hip Horse Pond) and dozens of ponds such as Qingshui Pond, Hebao Pond, Bracken Pond, Garden Pond, and Iron Helmet Pond.

On the one hand, it can increase the rainwater regulation capacity during heavy rains in Qianzhou, reduce the area and time of street inundation, and on the other hand, it is possible to use ponds to raise fish and silt to grow vegetables.

Because after the two ditches are built, the shape resembles the ancient seal body Fu and Shou two words, so they are named Fu and Shougou respectively.

Banxia listened to it from the sidelines and marveled, the wisdom of the ancients is really not to be underestimated.

But now that the three of them are stuck in the problem of seawater backflow, Banxia thought about the design of the modern drainage system and said, "It's better to add some round metal covers above the drainage outlet of Fushougou." ”

The three of them instantly understood in seconds, and they were overjoyed: "Why didn't I think of this method." ”

Tongzhi Xu praised: "Madame is smart, adding a water window is indeed a good way." ”

The three of them looked at Banxia with bright eyes, and Banxia smiled embarrassedly: "I also saw it in the book when I had nothing to do." ”

"When the sea water level is lower than the water window, with the help of the ditch, the water window automatically opens and drains the water; If the sea water level is higher than the water window, the water window will be automatically closed by the power of the seawater. The more the master spoke, the more excited he became.

"Fushougou uses the terrain height difference to drain the water in the urban area, and the exquisite design of the water window will definitely allow the people of Qianzhou to get rid of the perennial floods."

Su Zhiyuan calmly analyzed: "Then we have to transform the original sewer into a rectangular section to increase the impact of the water, and we have to use bricks and stones to build a fortress to be firm." ”

Tongzhi Xu agreed: "The width of the section should be at least 90 centimeters and the height should be 180 centimeters. ”

Su Zhiyuan put the map in the middle: "Fushougou is crisscrossed to all corners of Qianzhou, and finally collected and discharged the dirty water of Qianzhou to Gonghai and Zhanghai respectively. ”

Everyone seemed to be ignited at once.

Su Zhiyuan said: "In a few days, I will hand over the fold to Beijing, and hope that His Majesty will approve the project of Fushougou." ”

Tongzhi Lord Xu said with a smile: "With the will of the Holy Lord, some rats, snakes and ants don't dare to blatantly make small moves. ”

The master shook his head: "This is a matter for the benefit of the people, as long as it is in Qianzhou, whether it is an official or a rich businessman, or a poor people, all of them are not troubled by floods, if there is really a good way to solve this matter, it is too late for everyone to be happy!" ”
