Chapter 944 Powerful Rock Chiseling Tools

The Qiao clan has already built preliminary adobe resettlement houses, and the immigrants from Takuhai County have also arrived. They have also started a new life like the village on Qiongzhou Island, except that their life here is a little more difficult than that on Qiongzhou Island.

When the Han tribe's immigrants went to Qiongzhou Island, there were at least ready-made villages there, and the local people had lived there for many years, and even the farmland was ready.

But now the Takuhai County immigrants and the Qiao clan's village have to start from scratch. The houses are all newly built adobe houses, and even the farmland has to be reclaimed by themselves. Fortunately, the Han tribe is familiar with such a situation. For completely newly built settlements like theirs, they will be tax-free for the first two years, so that the local villagers can gain a foothold as soon as possible.

On the other side, the fleet that set out at the same time as Tang Yao and Mo Xin finally arrived late. These three-masted sailing ships were far behind the speed of the flying fish. Mo Xin and his crew had already arrived at the construction site of the capital. The Qiao immigrants who had picked up the goods on the way had already planted the land. These sailing ships had just arrived at the dock of Takuhai County.

This shows how necessary it was for the Han tribe to develop flying fish-type sailing ships.

The fleet loaded with a lot of construction machinery and reinforced concrete did not dare to stay. After replenishing food and fresh water at the dock of Takuhai County, they began to head towards the sea. Under the guidance of the three newly built lighthouses, they headed all the way to the end of the strait between Qiongzhou Island and the mainland.

This journey took another ten days, and it was not until the end of May of the first year of Da Ming that the fleet finally arrived at the destination.

At this time, the construction site of the cross-sea bridge was still as busy as before. Barges carrying sand and stone sacks came one after another. From time to time, there were earth-shattering explosions on the mountain on the dark bridge continent. After the huge mountain was blown loose, it was put into sacks by a large number of slaves and transported to the ship at the dock. Finally, it was thrown into the sea to build one pier after another. Pier wells.

A few months have passed. The project planned a thousand piers, but now there are less than a hundred working positions for building waterproof dams. Among these dozens of piers, less than ten prefabricated wells have been dug. Because of the backward tools, this work is indeed progressing very slowly. Fortunately, this fleet lived up to expectations and finally sent them a lot of good equipment.

The person in charge of the fleet transporting this batch of materials is a researcher at the Power Research Institute named Jiao Ce. Jiao Ce is not responsible for the train project in the institute, but for various steam-powered machinery, such as stone crushers, grinding mills, steam-powered mixers, and air compressors, as well as the research and development and operation of related tools. Therefore, it is best for him to be responsible for escorting and guiding the construction.

The fleet docked at the temporary wharf of the construction site. Jiao Ce was invited to the engineering command center as soon as possible. Looking at the huge sand table in front of him, the bridge model next to it, and the command team around him, he could clearly see the anxiety of these people.

"This project is too large. With our way, there are still 10,000 prisoners of war. Even if we work for another ten years, I'm afraid we can't complete this project. I'm afraid our generation can only dig the prefabricated wells of more than 1,000 bridge piers." Elder Zhu Pingzhu, who is in charge of the project, said pessimistically.

"Yes, we originally thought that we had attached great importance to this project, but when we actually operated it, we realized how difficult it was. This is not a project that can be completed by manpower at all. We all underestimated it." Another craftsman in the command team also sighed.

But Jiao Ce was very confident. He clapped his hands to attract everyone's attention, and then said.

"Everyone, you are right. The workload of this project is really huge. It is really difficult to complete it with manpower alone. But please don't be discouraged. Behind you are the tribe, the leader, and our institute. Although we did not personally participate in this project, we have also developed a lot of good tools for you. Since manpower cannot complete it, let us use machines to replace manpower!"

"Oh? I don't know what kind of machinery Master Xiao Jiao brought us, but the steam engine that can rotate in circles when burning fire? But what role can that steam engine play here?"

Zhuping also has some understanding of what the Han tribe has made recently. He has heard of the iron thing that can rotate in circles as long as it burns fire and drives many things to do work, but he has never seen it. However, he still can't think of what help that thing called steam engine can bring to their project.

"You certainly can't use the steam engine directly, but the steam engine as a motive force can drive many other machines, such as air compressors, which are a new type of machinery we developed using the working principle of steam engines. This thing can replace you to do many things.

"Are you interested in going with me to take a look? "Jiao Ce introduced what he brought to them and invited them to visit.

"Of course I'm interested, Master Jiao, please lead the way. If what you brought can really come in handy, we will treat you to a seafood dinner." Another old master in the command team spoke.

"Ah? No, no, no, no, I've had enough seafood on the boat, don't let me eat seafood again, although that thing has a lot of meat, but there is not much fat, I don't think it tastes very good. After I finish looking at the things, I don't want any seafood. If you can stew a chicken for me and give me two bowls of rice, I will be very satisfied. "

When Jiao Ce heard that these people wanted to treat him to seafood, he shook his head like a rattle, saying that he only wanted to eat stewed chicken with a bowl of rice.

This naturally caused everyone to laugh. It is not easy for them to eat chicken here.

After all, those who guard the bridge never get to eat chicken.

Ah, no, they are bridge builders. Although there is no shortage of meat on the construction site, they can only eat sea fish as the main food. There is plenty of fish and meat. Seafood makes them want to vomit, but chicken? Sorry, no.

A group of people went directly to a ship in the fleet, and under the leadership of Jiao Ce, they went to visit the machinery on the ship.

After some tossing, everyone came directly to a small iron horse steam engine. Interestingly, there is another thing like an iron can with legs connected to this Mustang steam engine, and then they listened to Jiao Ce's introduction to them.

"Ladies and gentlemen, this is an air compressor driven by a steam engine. It is also a power source. However, this power source can drive many things. Wait a minute, I will show you how to operate this thing. "

Jiao Ce introduced it to them while directing the crew to put the air compressor on a small sampan, which was a small boat without sails and could only be rowed with oars. They also put some other supporting tools on it, as well as a lot of pipes wrapped in canvas, as well as firewood and coal, and then rowed straight to a construction site where a pre-placed well for a bridge pier was being dug.

After another round of tossing and turning, with the help of dozens of craftsmen, they finally got these things into the construction site, and they also walked down in circles along the built sea dam.

"First, light the stove and inflate the air compressor."

"Yes, sir, don't worry."

Jiao Ce first arranged for an intern who came with him to burn the boiler, and then continued to introduce it to others.

"Dear seniors, this is the air compressor and its supporting tools. With these mechanical tools, your project progress will definitely be greatly accelerated."

Jiao Ce pointed to the two slaves who were holding sledgehammers and chisels and digging the dark bridge reef not far away, and said to the command team of the project.

"At present, your main task is to build a dam and then dig a pre-set well, right? There is no labor-saving way to build a dam. You can only use earth to fill it, but digging a pre-set well is different. Look at the rocks on the reef under your feet. If you dig it with hammers and chisels like they do, how many lifetimes will it take to dig a well?!"

Hearing Jiao Ce's words, all the big guys present sighed. Isn't it true? Which of them present would not understand, otherwise why would they sigh?

Then Jiao Ce continued to say.

"Among the tools I have here, there is one that can replace their work, such as this air hammer, which is specially used for chiseling rocks or hard objects. Such an air hammer only needs one person to operate, and it can replace the manual chiseling of ten laborers like them."

"Oh?!"

"Is it really that powerful?!"

"This thing looks pointy, it looks like a chisel, why is it called an air hammer?!"

At this time, before Jiao Ce could answer, the steam engine over there finally heated up, reached the power to start working.

The steam in the boiler rushed into the small cylinder of the Iron Horse Type 1, pushing the piston inside to reciprocate, and then driving the connecting rod and flywheel to rotate rapidly, and then through the transmission of the V-belt to drive the air compressor to work. As soon as the air compressor started running, a huge noise of thumping sounded at the scene, which scared everyone present.

"Don't panic, this is a normal reaction when the air compressor is running, and a little noise is not a problem." Jiao Ce calmed everyone down and continued to introduce.

"Now this air compressor is working in the gas storage stage. When its noise stops, it means that the air in the cylinder has been filled to the maximum pressure value. At that time, we can use it to drive the air hammer to work."

"It sounds so troublesome. If there is no air compressor, won't even this air hammer be used?"

"I think this is not a big deal. The key is efficiency. If one air hammer can really replace ten people, it's okay to take a break while it is storing air."

"Yes, it is very, very, the key is efficiency."

"But this thing seems to burn charcoal, but if compared with the rations to feed ten people, it should be more cost-effective to burn charcoal."

Just as the command team was discussing, the air compressor over there finally made a hissing sound of deflation, and then it became quiet.

"Okay, seniors, the air compressor has reached the maximum air pressure and is ready to work. Now let me show you how to use the air hammer."

Jiao Ce said as he tucked the hem of his robe into his belt, rolled up his sleeves, and began to straighten the rubber air pipe wrapped in canvas.

"Everyone, please pay attention. This thing wrapped in cloth is the rubber air pipe. It is very precious. Be careful not to break it, otherwise it will be very troublesome to repair it."

Jiao Ce first unfolded the rolled air pipe, placed one side on the air compressor and the other side on the air hammer, and then he held the spring air valve at one end of the pipe and said to everyone.

"Do you see this iron lump? When using it, you need to put it on the air inlet of the air hammer. The other end also has the same iron lump, and then put it on the air outlet of the air compressor. After connecting them, you can use it."

Jiao Ce first demonstrated the connection method to everyone. After both ends were connected, he carried the air hammer weighing dozens of kilograms to a rock that was ready to be chiseled. He smashed the chisel under the air hammer heavily on the rock. The pure steel air hammer chisel immediately smashed a small hole in the rock. Then he continued to introduce the method of use to everyone.

"Please look at the ring handle above. When using it, you need to separate your feet, stand firmly, put your hands on the handle, and then look at the wrench inside the iron ring. This is the place to vent air. As long as you squeeze this wrench, the high-pressure air stored in the air compressor over there will enter the air hammer and start working.

"Okay, I'm going to start the demonstration now. Everyone pay attention. "

Jiao Ce took a good position, aimed the air hammer at the rock of the reef, and pulled the trigger in the iron ring. High-pressure air instantly rushed into the cylinder in the air hammer, and began to drive the steel chisel at the bottom to do reciprocating work in the cylinder.

In an instant, the air hammer made a series of thumping sounds. Each thump represented that the steel chisel had done reciprocating work once, and the steel chisel had also chiseled the stone once.

The thumping sounds continued, and in just a few seconds, a piece of rock under his feet was completely shattered, turning it all into stone fragments, and the surrounding gravel flew.

Thump thump thump - thump thump thump -

Jiao Ce kept changing positions with the air hammer, pulling the trigger for a few seconds each time, and letting go immediately after the stone was broken. While demonstrating how to use the air hammer, he also introduced it to everyone.

"You should have seen that this air hammer is definitely a powerful tool for chiseling hard objects. However, it uses high-pressure air as power, and because the gas stored in the high-pressure gas cylinder is limited, when you use it, don't hold the switch like this. First, it is difficult to control, and second, the high-pressure gas is consumed too quickly. If you hold it and don't let go, it will soon be inflated again, and then the air hammer can work."

While Jiao Ce was talking, his hands were not idle. He had already smashed a large area of ​​reef under his feet into rubble, which stunned the bigwigs in the command center.

This thing called an air hammer is too exaggerated to be used to chisel rocks. One

thump, thump, thump is equivalent to several hits of human hammering? !

It's simply against the sky!
