Chapter 30: Undersea piling (seeking further reading)
Chapter 30 Seabed Piling (please follow up)
Two large sampans arrived at the west side of Dandan Island, about two nautical miles away from the tidal flat.
Li Duoyu stopped the boat.
“Master, stop here and wait for us to drive piles here.”
Chen Dongqing looked at the surrounding sea:
“Are you sure you want to grow kelp here?”
“Yes, I think this area is very good.”
Chen Dongqing originally found a suitable breeding area for him. Since he said so, he would help him take a look first.
He leaned down and checked the visibility of the water, and roughly checked other data. The result surprised him.
He told Li Duoyu once about the suitable environment for kelp to grow, and unexpectedly he remembered everything.
And Chen Dongqing feels that this sea area is most likely the most suitable place for kelp cultivation on the entire Dandan Island.
The sea water is clear and the visibility is more than two meters.
The flow of sea water is also quite large.
There is a tidal flat not far away, which also meets the conditions of fertilizer and water.
Chen Dongqing couldn't believe it and said to the piling master:
“Master Zhang, please try to find out.”
Hearing this, Zhang Zetian used multiple sections of bamboo poles to pick up a long stick more than 20 meters long on the boat. Every other section of the stick had a red mark with numbers on it.
The other end of the long stick is tied with an iron piece more than half a meter long, which looks a bit like a "meter spy".
Li Duoyu knew that the iron piece was used to explore the bottom of the sea. As long as he stabbed it down and pulled it up, he could roughly judge what was going on under the sea by looking at what was left on the iron piece.
After stabbing the long bamboo stick down, Zhang Zetian stabbed it hard a few times, then slowly lifted the bamboo stick up and reported a set of data:
“The water is 23 meters deep and has a sandy bottom, so piles can be driven.”
After hearing this, Chen Dongqing, who should have been very happy, looked at Li Duoyu in front of him and felt clearly jealous.
Since Li Duoyu came to the Fisheries Research Institute some time ago, he has been wondering why he looks so relaxed in everything he does.
Chen Dongqing sighed:
“Okay, tie the anchor rope and prepare for piling.”
Under the command of Chen Dongqing, the two sampans came close to each other. A worker selected a thicker wooden pile and then tied the thickest anchor rope tightly.
Like picking up a bamboo pole, Lao Zhang picked up a long iron rod, and a hammer weighing about two hundred kilograms was welded to the other end of the iron rod.
Four thick ropes are tied to the top of the hammer.
The piling masters lifted the hammer to the sea, and then a man with good water skills tied the wooden pile used for piling to a groove on the side of the hammer with a slip knot.
The next step is to use the weight of the hammer to drive the stake vertically to the bottom of the sea.
Then untie the slipknot.
Then you can start piling. Every two people pull a rope, and the people on the two boats pull up the hammer together. As the most important piling hand, Lao Zhang must ensure that each time the hammer is lifted, it will hit the ground. On the wooden pile.
Until the entire wooden pile is driven into the sand.
The beating goes on.
The pile is stronger.
If the hammer misses the mark, or the stake is crooked, you have to pull out the stake and start over.
When piling is being driven, the masters will shout the piling horn together.
“Ooh, oh, oh,
Hold it high, oh oh
Hit the prison well, oh oh
The typhoon is coming, hoo-ho
It can’t be blown down, oh oh”
After hearing this slogan.
Li Duoyu felt a sense of intimacy. It had been years since he heard fishermen shouting slogans. He remembered that when he was a child, the fishermen would work together in a collective and there were all kinds of chants.
There is a signal for pulling the net.
There are also horns for rowing oars, pulling boats, and knocking oysters.
After probably hitting it more than thirty times.
When Lao Zhang felt the iron rod and found that it had been hit to the bottom, he would ask everyone to pull up the hammer. After making sure that the hammer has hit the sand, let two or three people pull the anchor rope to ensure its firmness, then drive a pile.
After they finished driving the piles.
Li Duoyu tied a big floating ball at the intersection of the anchor rope and the rope.
After tying the big float.
The piling boat will drive forward 50 meters along the current. Li Duoyu once again tied a big floating ball, and then Lao Zhang and the others continued to drive piles here.
Generally, the length of kelp rope is fifty meters. If it is too long, it will be easily pulled out by strong waves in strong winds and waves.
The first time we collaborated, it took everyone more than half an hour to get a 50-meter-long rope.
Li Duoyu’s 30 acres of kelp farming land requires a total of 150 ropes.
According to the current piling speed, it will take at least eight or nine days to complete.
Fortunately, Lao Zhang charges per pile.
The charge for each pile is 1.5 yuan.
If all the more than 300 roots are beaten, it will only be about 500.
Under the scorching sun, a group of pile drivers kept repeating the same piling operation. In less than two hours, everyone was soaked to the skin.
When the sun rose to its highest point, the piling masters all sat on the boat deck, drinking tea and taking a rest. Some of them took off their clothes and covered their heads to prevent being exposed to the sun.
Although Chen Dongqing, who has thin skin and tender flesh, is wearing a bamboo hat, his arms are all red from the sun. This is the hardest and most caring time for him since his work.
Li Duoyu was tired and slumped there because he had to keep tying various floating balls. He looked up at the blue sky and was thinking about life.
It took a whole morning to get two acres.
There are still twenty-eight acres left.
Thinking of this, Li Duoyu felt a little numb, but he had to accept the fact that production efficiency in this era was low.
Forty years later, using a pile driver, more than 300 wooden piles could be driven in less than two days.
Sure enough, developing science and technology is the last word.
While they were resting.
A small sampan boat came towards them. After Li Duoyu glanced at the people on the boat, he stood up, waved to them and shouted:
“Aniang, this way, this way.”
It was the third uncle who drove the boat and brought his mother over to deliver food to the piling master.
The ship is approaching.
Chen Huiying moved a basket of light cakes to Li Duoyu's boat. Li Duoyu quickly reached out to pick it up. The light cakes had just been baked and still exuded a strong burnt aroma.
Li Duoyu, who was hungry and had his chest pressed against his back, picked up one and bit it on the spot. Although this kind of cake was fragrant, it was very hard and had to be bitten hard.
Most importantly, it is very filling. It is said that when the Qi family army was fighting against the wandering Japanese pirates in their area, they ate this kind of light cake.
Chen Huiying talked about her son:
“Do you understand the rules? You should let the master eat first. I haven’t even thanked Uncle Qin properly for sailing all the way here to bring you food.”
“How can there be so many rules for rough people who just urinate into the sea.” As soon as Li Duoyu finished speaking, the pile driving masters burst out laughing.
Chen Huiying looked disgusted and cursed: "You kid, how can you talk?"
Li Duoyu took two more bites, and then immediately distributed the cakes to the piling masters. When Chen Dongqing saw his sister, she greeted him with a smile:
“Sister.”
Chen Huiying looked at Chen Dongqing:
“I seem to have gained weight and am not as thin as before. Have you eaten the food I brought you last time?”
“I ate it, Xiaoqing said it was delicious.”
“As long as it’s delicious, I’ll ask Duoyu to bring you some after you finish eating next time.”
“No need to bother, last time we had enough food for half a year.”
Chen Huiying saw that most of the piling masters were shirtless. As a woman, she was too embarrassed to continue chatting, so she went back with her third uncle's boat.
Li Duoyu ate three pieces of light cake in a row.
After taking a big gulp of water, I burped, and then continued to tie the float ball.
