The so-called big project is actually that the supporting facilities for tap water have been developed.
In fact, there are two things, a steam pump and a threaded link.
The steam pump is actually very easy, just connect the crankshaft to the water press.
Build a shelf and put a water tank on it, pump the water up, and you can have pressure to make tap water.
The main difficulty is the threaded connection of the water pipe and the supply of the water pipe.
Last year, in the two wars with the King of Suzhou and the Liu brothers and sisters, a large number of prisoners were captured.
In addition to those who were disbanded on the spot and those who were reorganized and enlisted, there were more than 3,000 laborers, all of whom were sent to Daye.
The total number of workers in Daye has reached 5,000!
The number of people has more than tripled, and production capacity and efficiency have also doubled.
Songtian suddenly had thousands of extra laborers, and Le was so excited that he couldn't close his mouth.
In the past, people from all over the country were urging him to increase production. I remember Song Tian wandering around the mine every day with a frown on his face like an ant on a hot pot.
Now that the manpower is here, the problem is solved immediately.
And there is good news. The steam hammer developed by Wang Jinshi has been put into use in Daye after half a year of trial operation.
Both machines and labor have been upgraded, and output has increased by leaps and bounds.
The large supply of materials makes it possible for Jiangzhou to carry out various developments.
So Wang Jinshi came to Song Yang and proposed to start laying water pipes.
Of course, the first phase must be a small-scale trial run.
Originally, the test was successful in the laboratory, but now the equipment needs to be moved outside for field operation in a certain area.
Song Yang listened to Wang Jinshi's words, thought about it and said, "Then let's do a trial operation in the workshop area first."
Considering that the workshop area consumes a lot of water, the priority supply of tap water here can also make production water more convenient.
The water used for forging every day is brought by workers from the well. Just doing this alone requires more than a dozen people to work continuously.
The plan was made and construction officially started the next day.
The water tank is built in the open space behind the smelting workshop, and there is a well not far from it.
This well has already been equipped with a steam pump, and a house has been built on top of the well to serve as a pump house.
Wang Jinshi did experiments here before.
Now connect the water pump to the pipe all the way to the new water tank above.
The water tank is made of clay, and the lid seals well.
This thing is actually an enlarged version of the large water tank used at home.
Song Yang was once worried about whether this thing would be strong, but in fact Song Yang's worries were unnecessary.
According to Wang Jinshi, it will not be a problem for this thing to last ten or eight years.
In order to ensure load-bearing, the lower shelves are made of strong logs covered with fine steel.
It took a whole day just to build this shelf, and that was with sufficient materials and personnel.
The water tank is set up, and an iron pipe is led out from it. The connecting place is sealed with mud, and a layer of iron is welded to the outside.
Song Yang initially thought that the mud seal would leak easily.
But when the water tank started to be filled with water, Song Yang found that there was no leakage between the water pipe and the water tank.
Once again he admired the skills of the craftsmen.
In order to ensure stable pressure in the water tank, a drift valve is installed on the water tank.
The speed of the water pump will definitely be faster than the speed of discharging water. When the water is almost full, the float valve will rise and drive the steam valve below to exhaust, so that the water will stop being injected.
This ingenious mechanism was thought up by Song Yang, because in his previous life there was a small coal-burning boiler at home, and there was also this kind of floating valve for deflating...
The water in the water tank was led back to the ground through water pipes, and a small house was built under the water tower as a water valve room.
Use bolt water valves to control the amount of water supply.
Otherwise, with the speed of the steam water pump, even if the upper water tank can bear it, the lower water pipe cannot bear the pressure.
The water pipes are laid starting from the water valve house and all the way to the blacksmith workshop.
The water pipes are three-meter fine iron pipes with threaded connections, which are tight and durable.
There is no raw material tape at the connection, just use straw rope, and the effect is actually good.
Including digging the pit and burying the pipe connection, this project took a total of three days.
Finally, connect the faucet in the blacksmith workshop and the matter is finished.
Speaking of faucets, Song Yang’s contribution must be mentioned.
Master Wang and others have been troubled by how to control the flow of water at the water outlet for a long time.
After Song Yang heard about this, he remembered that there was no such thing as a water dragon in this era.
So he put it on the encyclopedia, and there was indeed a relevant introduction.
According to the introduction, Song Yang hand-drawn the drawings and presented them to Wang Jinshi.
Wang Jinshi was amazed after seeing it.
Thus, the first faucet in history was born.
Pure copper, no rust!
The faucet is connected and the water line is completed.
Of course, Song Yang must complete the ceremony of opening the water dragon for the first time.
On January 20th, Song Yang, Fang Zhe and others held a ribbon-cutting ceremony at the entrance of the water house of the blacksmith workshop.
Then Song Yang personally walked into the water room and turned on the first tap in the history of Daqian.
"Wow~"
The faucet was opened, and a stream of clear water, ranging from small to large, flowed out of the faucet.
"Bah bang bang!"
The audience clapped their hands and applauded.
"This thing is really convenient. It's much easier than pressing a water well. Just twist it and you'll get water!"
"Yeah, I won't have to fetch water anymore!"
"Our place already has a lot of water, and it takes more than a dozen people to fetch water every day. Now we can save more than a dozen people!"
"Why don't you talk about the prince's fantastic ideas?"
Looking at the clear water flowing out, Song Yang smiled with satisfaction.
Tap water was successful, which also provided water supply guarantee for future urban layout.
Of course, there is still a lot of room for improvement in the water supply system.
For example, iron water pipes, water pipes made of iron are easy to rust.
Now that clear water can be released, Wang Jinshi actually let people release a period of turbidity before.
Otherwise, the first sip of water will definitely be rusty water that is as muddy as mud.
In fact, the iron water pipes of later generations also had this problem. After a period of time without water, they would become very turbid.
There is no good solution for this at the moment.
Materials such as PVC are still far away and cannot be considered for the time being.
However, the rust prevention of iron pipes still needs to be studied.
After all, the rust on the inside can be flushed out, but the rust on the outside cannot be helped.
If you are not careful, the iron pipe will easily rot if time passes.
Song Yang and Wang Jinshi discussed this point and gave some suggestions.
Coated with a layer of anti-rust film.
How this matter will be carried out will have to be decided by Wang Jinshi.
Zinc mines are mined in Daqian and Daye, mainly used for copper smelting.
And now Daye has some reserves, which are incidental products from the iron ore.
Song Yang and Wang Jinshi told Wang Jinshi that the water pipes should be galvanized. Wang Jinshi tried it, but it has not been successful yet.
Song Yang only knew that galvanizing was needed, but the encyclopedia didn't mention the specific plating method, so Wang Jinshi's team had to figure it out on their own.
Fortunately, there is a general direction, which can save some effort when searching.
