The forge shop originally had a free-fall hammer that was used locally, but it was not very efficient. Barely able to make do. As the level of industry continued to improve, the maniacs of the machine factory were ready to abandon this earthen equipment and build a 100-ton hydraulic press, but later found that this goal was too big, and decided to start with a more primitive means: making a steam forging hammer - this thing is not of high level, but the effect is sufficient. There are two steam forging hammers manufactured around 1880 in the Jiangnan Shipyard, which are still in service in the 90s of the 20th century, and the pedestals are broken, and the Jiangnan Factory is reluctant to dismantle them, and they continue to be used for repairs.

With the steam forging hammer, the forging of many large workpieces becomes much easier. The 5-metre-high slides of the steam hammer are made entirely of steel and stand on a granite and reinforced concrete base. The hammer on top weighs 1 ton and is driven by a steam propelled sliding valve.

Compared with a free-fall forging hammer designed and manufactured by the machinery factory earlier, the forging capacity and work efficiency of this forging hammer have been increased by less than three or four times. Originally, it was very difficult to use the forging hammer, and it was necessary to continuously operate the steam engine to lift the forging hammer, and then use the cam clutch to control the release.

The mild steel jaw plate was quickly machined in the forging shop, and then the toggle plate and eccentric shaft were manufactured in the same way, and the eccentric shaft was then taken to the lathe to be turned and formed to make it as round as possible. Zuihou made two large flywheels with a diameter of 1.2 meters, which were used to connect to the power engine.

The giant parts were loaded onto the ox cart and slowly dragged to Nanbao. Because of the limited carrying capacity of the ordinary four-wheeled ox cart, it was mounted on a large flatbed cart with 16 wheels, specially built and pulled by 12 oxen. Whatever the usefulness of this thing, the convoy alone was enough to generate onlookers and talk -- and the people along the road were amazed at how much the Australians wasted steel.

The equipment was installed in the newly built workshop 1 of the Nanbao mine. The No. 1 workshop is a large-span iron truss workshop made by Bingfeng, which is as tall as a three-story building. The structure is supported by reinforced concrete columns. The floors are poured with concrete and iron rails are installed to push the ore.

A crane was installed on the roof of the workshop to transport a large dump bucket to load the crusher - according to the endless view, it was better to use a belt conveyor, but for the time being they did not have a suitable substitute, and if it was made of deerskin, it would be too luxurious.

Zuihou Xiao Guilai installed a steam engine. zuihou, the system is finally installed. A huge procession of steel and a huge base, weighing about ten tons, stood in the center of the workshop, not to mention the indigenous workers, and even the traversers themselves were amazed.

As Xiao Gui ignited the boiler, the steam engine slowly rotated, and under the transmission of the large gearbox, the Zuihou stage transmitted the power to the flywheel of the crusher through the belt, and with the gradual increase of the speed of the flywheel, the crusher began to work officially.

Workers carry a cart of large boulders through the tracks, using flatbed rail cars. The overhead crane on the roof uses a steam engine to drive the pulley, and soon lifts a huge stone into the crusher. Bang dang, bang dang, the crusher runs unhurriedly, the movable jaw plate slowly opens and closes, and the huge stone blocks sink deeper and deeper with the opening and closing of the jaw plate, and the clamp becomes tighter and tighter. The stone began to crumble, and many debris flew out, and with a crash, a puff of white smoke rose and the stone shattered into several pieces.

Everyone present was shocked, but the people at the machine factory knew that this thing was working normally

The jaw plate is still squeezing slowly, and the stone that has become smaller after breaking is clamped tighter and tighter in the process of descending, and continues to withstand the squeeze of the movable jaw plate and the fixed jaw plate, and continues to crumble.

Some gravel and powder began to appear at the outlet. 100% of the dust began to spread. Then a large pile of gravel falls on the bucket truck at the outlet.

Below the discharge port is a track, and a group of bucket trucks are connected end to end and stop under the discharge port. They were cabled to a steam engine-driven winch. Once one truck is full, the operator starts the machine and pulls the truck, and the second truck can be moved under the discharge port until one row is fully filled, and then the second one.

The loaded bucket cart unit is pulled to the loading station on the slope, where it is directly dumped in the body of the ox cart and transported away. The need for manual loading and unloading throughout the process is reduced to a minimum.

Zhan Wuya calculated that if only the crushed stone used in construction was crushed, the crusher could process about 50 tons of crushed stone every day, and if these crushing work were done by manpower, there would be no three or four hundred people who could not do it.

And now, even the maintenance workers of the boiler and the personnel who operate the overhead crane are counted, and twenty workers in one shift are enough. The difference in labor efficiency can be described as earth-shattering.

But to the local people, this rumbling stone crusher represents a terrifying power. Such a hard boulder can be bitten to pieces, what else can't this group of Australians do?

But the surprise was not over, as the first day the crusher proved to be usable, and over the next six months, three more crushers were installed at the Nanbao concentrator. This has a devastating effect on the locals.

As a result, the Crossing Group has been able to do whatever it does on the ground. The local gentry and common people simply obeyed. In addition, many people who were not very interested in working as workers in the mines have come to do odd jobs. Even the landlords and gentry sent a few domestic slaves or their sons and nephews to work - in order to get in touch with the mines.

With enough gravel, the traffic department's hardening of the road surface is progressing quickly. Shan Daoqian uses gravel as the roadbed to increase the bearing capacity of the roadbed, and then uses cinder and fine sand and gravel on the surface to smooth the road surface. After a few more crushes, the road was as smooth as new - a little more advanced than the lower roads in the countryside in some places.

In addition to the rollers on construction machinery, Shan Daoqian also cooperated with machinery factories and vehicle factories to develop animal-powered rollers - this is simple, but a huge stone roller with animal-powered traction belt. Slightly more complicated are animal-powered rakes, sprinkler trucks and pavers. These can now be pulled by horses, cattle or manpower. These special equipment not only reduces the wear and tear of construction machinery, because it is able to produce its own equipment, it is not too rare, the transportation bureau ordered several sets at once, and started to use at the same time on many road sections.

Shan Daoqian applied to Wu De for dozens of workers, set up a road maintenance engineering office, built road maintenance stations along the way, and also formulated regular and regular inspections, maintenance and maintenance work rules for highways.

"There's another thing, it's about traffic rules." Shan Daoqian found Wu De.

Originally, Lingao did not need traffic rules, except for pedestrians, there were at most a few sedan chairs and a few wheelbarrows. Occasionally, a few horses pass by. No matter how narrow the dirt road is, no matter how uneven it is, there will be no traffic accidents. But now it's different. The arrival of the crossing group has greatly increased the complexity of the road conditions, in addition to the increasing number of pedestrians, there are also ox carts, livestock, bicycles, cars and motorcycles. The construction of roads has also brought new problems, such as intersections, bridges, etc., which require a certain degree of control - there have been several traffic accidents recently.

"Leave this matter to the police." Wu De said, "The rain blowing at the east gate is just in charge of this." ”

Because he has been responsible for the management of Dongmen City for a long time, he has some experience in this kind of thing. He said: "I don't think there is a need to make too complicated traffic laws and regulations for the time being, first, the people can't remember it, and it is difficult for us to publicize it; Second, we don't have so much manpower to do on-site surveys and so on. ”

At that time, Liu Bang only had three chapters of the law when he arrived in Guanzhong. Although it is a great retrogression from the perspective of legal science, it is easy for the masses to understand and grasp and is easy to accept in the initial stage.

The basic principle of blowing rain at the east gate is: "Kao walks on the right, surpasses on the left, and divides the fast and slow lanes." ”

According to the rules, pedestrians, palanquins, and livestock take the slow lane, and horse-drawn carts, ox carts, and motor vehicles take the fast lanes - it stands to reason that the speed of motor vehicles and ox carts is very far apart, but motor vehicles have recently rarely been on the road, so as not to cause traffic chaos.

Herds of livestock, such as cattle and sheep, are not allowed to go on the road, but only to walk under the roadbed. Large herds of livestock on the road can easily cause road blockages.

Shan Daoqian said: "However, it is better not to honk the horn of the motor vehicle, so as not to disturb the livestock." And it's wishful thinking that you expect a heavy ox cart on the road to make way for the road. Or do you belong to yourself, and you just overtake it. ”

"There's got to be a little punitive, what if a pedestrian walks on the side of the road, and what if he likes to walk in the middle?" Dugu asked.

"KAO fines are not okay." The east gate blows rain and drags his chin, "First, implement the concept of hitting and killing in vain, and if you violate traffic rules and cause casualties and property losses, you will not be compensated-"

"Slow, that's not the point," Shan Daoqian stopped him, "I agree with what you said, but now let's talk about the general minor violations." As far as our current shili is concerned, even if a few people are really killed, no one dares to ask for an explanation. ”

"Arrest the labor camp!" Dugu's marriage proposal was used in this way.

"It also increases the workforce." I also think it's okay to blow the rain at the east gate, anyway, now minor offenses are compensated with hard labor, ranging from three days to three months.

Shan Daoqian said: "I think this is good, all the people who are arrested for violating traffic rules will be assigned to our transportation bureau for use." ”

The transportation bureau has many projects and affairs, and the more free labor, the better. Not only to build bridges and pave roads, but also to direct traffic
