Great changes in the countryside

Chapter 44 New Sand Washing Method
Wang Guangrong told Chen Yang that Technician Liu was specialized in sand washing, and he was specially invited to guide Chen Yang in sand washing.

Chen Yang was overjoyed, he was worried about the low efficiency of sand washing.

Technician Liu first asked Chen Yang about the current sand washing process.

Chen Yang said it in detail.

Technician Liu suggested that the two stages of sand washing should be combined into one stage.

That is, after the sediment is dug up, do not wash it on the boat, but transport it back and wash it together.

For the entire sand washing process, technician Liu also suggested that they use the "five-step method" of their sand washing factory.

Regarding what is called the five-step method, technician Liu also explained in detail.

Chen Yang is smart, and once Technician Liu said it, he basically understood it.

The so-called five-step sand washing method is to make full use of the slope of the embankment and dig pits on the slope to wash sand.

Wang Guangrong asked Chen Yang if he understood.

Chen Yang said he understood.

Wang Guangrong and the others stood up and said goodbye.

It was almost noon at this time, Chen Yang was very embarrassed.

The guests came from afar, and they came to discuss business. They should have invited them to dinner.

Besides, Chen Yang is not short of money now.

But Chen Yang was not prepared.

"Section Chief Wang, I'm really sorry, I should have kept you for dinner."

Wang Guangrong patted Chen Yang on the shoulder and said with a smile, "We are friends now, and there will be many opportunities to eat in the future. This time, we will avoid it. When you make a lot of money, if you don't invite us to a big meal, we will definitely not agree." .”

After being polite, Chen Yang sent Wang Guangrong and the others away.

The two parties agreed that after ten days, driver Li would bring the money and drive a motor boat to transport the sand.

On Chen Yang's side, he dug a hole on the slope of the embankment according to the method taught by Technician Liu.

The five-step sand washing method requires digging four pits along the slope.Arranged in a line from high to low, from large to small.

There are two difficulties.

The sediment dug from the river must be loaded into the top pit.The drop is two or three meters, and the distance is at least five or six meters. How can the sediment be transported up?

Also, how can the water for sand washing be transported to the pit?You can't pick it up one by one, can you?

Chen Yang threw two difficult problems to the two elderly people, his grandfather and Tong Erzi's grandfather.

There is an old saying that ginger is old spicy.

There is also an old saying that one old man in a family is like a treasure.

What's more, there are two treasures now.

Build a wooden platform by the river, and then make a wooden trough. The silt in the boat is poured onto the wooden platform first, and then the silt flows from the wooden platform to the No. [-] pit.

As for the water for washing sand, it is also easy to solve.Along the sides of the four pits, make a waterwheel.By turning the water wheel manually, water can be supplied to the four pits respectively.

There is a solution, and everyone gets busy.

Together, Chen Yang and Tong Erzi took the handcart to the Woodworking Club of the commune to buy materials for making waterwheels and wooden platforms and troughs.

However, Chen Yang didn't listen to Technician Liu. He cut corners and reduced the size of the four pits by a quarter, and the depth was reduced from 1.5 meters to [-] meters.

Also, according to the design of technician Liu, the four pits are arranged in a line from high to low.Chen Yang also made a modification. He changed the No. [-] and No. [-] pits to be side by side, and the No. [-] and No. [-] pits to be side by side, which greatly shortened the distance between the four pits and the river surface.

Chen Yang understands a truth, anyway, he can't listen to others.

That is to say, farmers have their own way of doing things and should not be too professional.

There is one more big puzzle to solve.

It is five miles from Chenjiacun to Sanchakou.Now there is only one boat. After the sand is dug up, it is transported back and then unloaded. One-third of the time is wasted on the road.

To borrow a boat or rent a boat.

Chen Yang thought about hitting Captain Tong Laogui again.
