In May, the weather is hot.

And the coal mine is in full swing.

The first steam engine cargo transport device in the Qing Dynasty was born.

This machine directly utilizes local coal mine resources to quickly transport coal to the foot of the mountain and remove water accumulation in the pit. After all, it has modern knowledge, and once this design comes out, it has a relatively complete foundation in many aspects.

The industry of the Qing Dynasty finally began its rich and colorful stroke.

Steam transport aircraft is a completely different concept from manpower. If strength is a hundred people, it is not its opponent. Moreover, it does not care whether the external environment is windy or rainy, and it can even work at night and does not need to rest throughout the day.

After Lao Shi made the steam engine, he did not invite Mr. Kangxi to take a look. After all, this coal mine is not a good place, and it is quite far from Beijing City, so it is not very convenient.

If you want to get rich, you have to build roads first. If the industry wants to expand, there are more requirements for roads.

Lao Shi decided to build a road from the coal mine, which would first be built near his and Jiu Ge’s village. However, as long as the road reaches there, the land price there will definitely rise sharply. After discussing with Jiu Ge, he bought all the barren mountains and prepared to carry out light industry in that area and build an industrial park. Then, as needed, he slowly repaired the road leading to other directions.

In any case, the current industry definitely does not use electricity, but only steam engines. The development of steam engines cannot be separated from coal. It is necessary to first repair the road from the coal mine to the villa.

It is best to build a straight road, but in fact this is impossible. You can build a bridge across the river, and you have to turn around when crossing the mountains. Some villas and villages need to take a detour.

Fortunately, they didn't plan to build any railway tracks, because the iron of the Qing Dynasty could not have been wasted such a waste of trouble for them, so they built yellow mud and stone roads.

A gravel road refers to a road where a layer of gravel is put on the roadbed. It was a relatively good road at that time. The first-class road must be a slate road, but that one cannot pave the way for a long distance, and it is too expensive.

The gravel road is very good. You should know that many official plank roads are just compacted by loess.

The gravel road was also very difficult at that time. It was mainly not that it was difficult to pave it, but that it was too difficult to transport it. It would be a big deal for an adult and strong man to carry a load of 100 kilograms. It would take a day to walk a few miles or dozens of miles. Of course, Lao Shi and the others would not do this. They used steam locomotives to transport stones. Wherever they built it, they would not have to go too far to carry the stones, and the steam engine itself still had a certain function of rolling the road.

Of course, because the road I just built is relatively soft, a double-layer roadbed is used here. First, use stones to pass the base, and directly mix clay and grass with a certain proportion as adhesive, and then lay the second layer according to the situation where the roadbed is pressed by a steam engine. This layer can be made of glutinous rice.

The roads are relatively narrow, and are basically one-way.

In this way, when one path is established and another path is cultivated on the side, it will be more convenient to transport stones.

So at this time, the steam engine can be opened upside down and on both sides, and basically two steam engines are produced to ensure that one can be used normally.
