Dry docks were invented by Zhang Ping, a native of the Song Dynasty in China. Pen "Fun" Pavilion www.biquge.info

As early as 977 A.D., Zhang Ping served as an enshrined official and supervised the wood affairs and shipyard of Pingdu.

At that time, when building a ship by the Wei River, it was easy to be washed away by the water, so I had to send one boat and three households to guard it, and thousands of migrant workers were recruited and transferred a year, which cost the people and money.

Zhang Ping then ordered the migrant workers to dig a large pit on the shore and build a boat in it, and after the boat was built, dig a hole, divert water into the pit, and the boat floated up and sailed into the river.

Later, this pit became known as the 'dock'.

This was more than 500 years before it was adopted by the British shipbuilding industry.

Zhang Guoan's Roman-style cement components helped Zhang Laoshi factory director a lot, he had not seen the bamboo reinforcement cement components, and when he saw the manufacturing method, he was overjoyed and said: "Lord, this is clearly a good object that God has given us------ and the dock door is just right for this thing!" ”

The dock gate of the dry dock is the large and chemical salt pan sluice.

Zhang Guoan said: "This is a method that people have come up with, and it is not God's business!" ”

Director Zhang said honestly: "Exactly, exactly." ”

The other factories of the shipyard are easy to do, and they are all solved by building bamboo houses.

Liuqiu Oshima is a place rich in bamboo, and the available bamboo is everywhere, but the best is located in the upper mountains of the Hachido River.

There, Zhang Guoan arranged for many natives to cut down bamboo all day, and then use rattan to weave bamboo rafts, and put them down along the Badao River.

In their stockyard, the bamboo is much taller than the wood.

The waste material after bamboo processing is also a good material for burning bamboo charcoal, but the charcoal rate is lower, which can only reach two percent, which is less than half of charcoal, but fortunately, it is a waste.

Of course, Liu Qian could not personally preside over the opening of the sulfur mine. He sent his second brother.

His second brother is called Liu Gang.

Liu Gang and other people involved in the development of sulfur mines in the north came to Zhang Guoan again this day, not because they were in a hurry.

Last time, Zhang Guoan said that he is now building the cement components for the wharf, and when they are all ready, they will go to the north of Liuqiu together.

The gang was bored at the time, and they really went to see how to build cement components.

They clung to the muddy mule-style cement. Comparing the hardness of the mud components, and talking about the salt drying plant, there is also a plan to open a cement factory.

So this time I came to him for this matter.

After hearing this, Zhang Guoan said: "You are mainly here to open mines and dye factories, and you don't have enough workers in this business------

Zhang Guoan now has more than 4,000 workers on his hands, but he feels that it is still not enough.

Now is the time of farming, a farmland water conservancy, a dry dock. For the production of building materials, there are no idle people in the entire Badaohe area, only these new investors and their skilled workers.

Liu Gang said: "I waited to see the so-called cement kiln, it was very simple------ a craftsman under a certain hand said that it was easy to build a bigger and better kiln!"

I'll wait for the discussion to be completed, and the manpower, and the people in each family are together, which can be regarded as a joint organization. ”

Say this. Zhang Guoan believes that people were originally looking for mining technicians. And the labor is also available.

Zhang Guoan agreed, after all, at this time, it is the time to have as much Romanesque cement as there is, and he is not afraid to open 10,000 shops.

It's still the old rule, Zhang Guoan waited for them to extract one-tenth of the product after production, and they readily agreed.

So later. Everyone in the Badaohe area is really busy.

Zhang Guoan is now taking advantage of the opportunity to build a river wharf in the north of Liuqiu, preparing for a standardized design of wharf components and related equipment.

He found that the largest and heaviest single item of cargo in this time and space did not exceed one ton, which of course had something to do with the fact that this time and space mainly relied on manpower to load and unload goods.

He designed a boom similar to that used in rural boom wells, which was of course much larger.

He added two tons of counterweight to the tail of the boom. The front of the boom plus can be replaced with pallet or net type supporting equipment, pig iron cast into a roller turntable, the roller is made by a blacksmith, one by one with manual grinding according to the same size, by four to eight people to operate together, although the steering is very difficult, but the work efficiency can reach about ten times that of manpower.

Other equipment of the wharf, such as trestle bridges and shore bodies, he is also prepared into cement components of a water, and when the time comes, as long as the selected wharf ground is compacted and then leveled, it can be directly constructed.

Therefore, the construction and development of the Yihe area is far faster than that of the Badaohe.

They themselves only produce a few tons of Romanesque cement a day, and except for the castle at the mouth of the river, it is not used for building houses, but basically for farmland and water conservancy.

Countless things have proved that the return on investment in farmland and water conservancy is quite high.

At the beginning of this summer, the southern part of Liuqiu began to have high temperatures and little rain, which greatly improved the yield of Zhang Guoan's salt pans, but also harmed his crop growth.

What God gives will never be all good.

Zhang Guoan often prays to God for a typhoon to drive away the heat and bring some rain.

Because he knew that even if the typhoon did make landfall, it would weaken if it came here again.

But God, as he said, never took the initiative to help people, and it rained a little rain or twice in the past few days.

Fortunately, he stepped up the construction of farmland water conservancy in advance.

A row of windmills and waterwheels on the Badao River are driving day and night, but this amount of water is far from enough.

An overflow dam they had built in advance on a small river five kilometers south of the Badao River saved their agriculture.

Due to the heightened water level, the water here can be self-flowing through the cement canal to irrigate the nearly 10,000 acres of paddy fields.

Zhang Guoan looked at the overflowing dam and thought that by the end of this year, it would have to be converted into an all-cement dam to raise the water level again, just in time to continue development to the south.

He looked at the countless wild grasses and miscellaneous trees on the south side of Xiaohe, and now, they were still in an advantageous position, and Zhang Anguo was powerless to deal with them.

After Zhang Guoan inspected a large circle, he saw that everything was operating normally, so he went to the farm that had just been set up in Jingjing.

Zhang Guoan learned the lesson of the last time and brought some more breeding poultry and small livestock.

For example, chickens, ducks, geese, dogs, and goats, and Quiet breeds them here first.

Zhang Guoan arrived at the farm and saw a lime box at the door.

There were countless footprints on the lime in that box.

He knew that this was for epidemic prevention, so he also stepped on his two feet lightly.

He saw Jing Jing and Shen Qianqian chatting while assembling a bamboo cage-style three-dimensional chicken rack.

Shen Qianqian said: "That sisal is very terrifying------ one by one, like a sword!" ”

Quiet said: "It's not scary, it's used to protect us, and the wild boar is afraid!" ”

Shen Qianqian said: "It's very quiet here at night, and I can hear the snoring in other bamboo buildings!" ”

Quietly said: "Do you like to live in a bamboo building?" ”

"I like it very much, I like the smell of bamboo!"

Zhang Anguo only remembered at this time that he had not yet developed a product called bamboo salt, which could increase added value. (To be continued.) )
