Chapter 284

The road hardening inside the tribe is far less difficult than the road leading to xiaoyanshan. The gaoshu tribe has lived here for more than 200 years. The roads in the tribe have long been hard to tread on. They only need to level the road surface, then use wooden boards to build molds, and then use the mixture of stones, river sand and cement to pave it. After ten days and a half months of maintenance, the road hardening project will be completely completed.

Of course, this kind of cement pavement is not as thick as 20-30 cm in later generations. After all, there are no trucks in the gaoshu tribe. Pointing to the weight of cattle and horses, 10 cm is enough.

However, when the road leading to the mining area is to be built in the future, the thickness of the road surface must be thickened, and the steel mesh must be lined inside, so as to ensure the firmness of the road surface.

Now the gaoshu tribe can't make the steel bar or rebar of later generations. Whether it's cold drawn or hot drawn, the gaoshu tribe is far from qualified. Not to mention the equipment, not even the power.

Therefore, the steel bars used by the gaoshu tribe are actually cast steel bars. Well, it seems a bit inappropriate to use steel bar as a description. After all, the tensile strength of this kind of cast "steel bar" is far from being comparable to that of real steel bar.

But the stone bear doesn't want to build skyscrapers, just build a road, at most, build a house, get a cement board or something, the application of such steel is not a big problem.

You have to eat one bite at a time. If you eat too fast, you either choke or hold on.

With David adian, who is proficient in metal smelting, and the golden finger of stone bear, I believe that in the near future, real steel bars and even rebar will appear in this continent.

The road hardening within the tribe was soon completed, and by this time, the biggest annual festival of the Cherokees, green valley, was coming.

The coming of Green Valley Festival means the coming of autumn harvest.

Now the area of farmland around gaoshu tribe is many times larger than that of spring sowing. This is due to the women who joined Xiaohe tribe. Of course, the people from Daqingshan tribe and the other two tribes also made great contributions.

In this era, the amount of manpower directly determines the planting area of grain.

Compared with other tribes, even in Europe, the farming method of the high tree tribe is undoubtedly extremely advanced. With the large-scale use of domesticated bison and the emergence of various new farm tools, the grain planting area of gaoshu tribe could not be expanded even if it did not want to.

The stone bear underestimated the North American seal of this era
