It is said that first "high-speed road" in my country with a length of more than 800 kilometers was built by Qin Shi Huang without grass.
In order to communicate better with people in other places, we invented highways, and with change of time, highway network in our country is becoming more and more dense. So what did highways look like in early days? What does first highway in our country look like?
Today, let's take a look atthe first expressway in our country with a length of more than 800 km, built by first emperor of Qin Dynasty, and some other measures have been taken in construction process, so that now expressway does not grow weeds on road, Let's figure it out together.
1. Acquaintance with Qin Zhidao
Qin Zhidao is not exactly same as expressway built in our country now. This is a road specially built for horse-drawn carriages by order of Qin Shi Huang under supervision of a general. It has a very important military value, and it took only two and a half years to successfully create it.
It was almost impossible in ancient times, so it is also considered a miracle in world. Moreover, during reign of Qin Shi Huang, four great projects with far-reaching significance were created, and Qin Zhidao was one of them. It also shows that Qin Zhidao occupies a very important position.
Qin Zhidao from Xianyang City to Inner Mongolia has a total of more than 800 kilometers, and there are different landmarks on different sections of road. For example, in some sections of road, city wall of Building was built, and in some areas a conspicuous stele was erected.
There are high towers built along the Qinzhidao Road at intervals so that you can see farther if you are standing higher, so that you can detect some anomalous events faster and react in time.
Given comprehensive consideration of this road, a large number of people consider this road first highway in our country and in history of mankind.
And after inspecting this expressway, people discovered a very unique phenomenon, that is, after more than two thousand years, not a single weed grew on this highway, so why is this woolen cloth?
Second, why doesn't Qin Zhidao grow grass?
When deciding to build this road, people first surveyed road to determine if it was suitable for road construction. After people understood, they found that soil on two sections of this road was not suitable for road construction. They are < strong>yellow soil and desert soil. Yellow soil contains many nutrients.
Meet vigorous life force of weeds and wildflowers, so weeds will grow on this stretch of road, destroying already built section of road. As for desert soil section of road, because soil does not have water capacity and is not rich in nutrients, although this soil conditions are difficult for weeds to grow, but extreme weather conditions can also cause natural disasters and hinder transportation of horses.
Therefore, after many discussions and planning by many people, it was decided to use human means to change composition of soil in soil of these two sections of road, making it more suitable for growing earthen grass.
And this method is to burn soil with fire and add some other ingredients so that life forces in soil are completely destroyed, ensuring that even if there are seeds in soil, nutrients cannot be absorbed. grow in soil.
Third, role of Qin Zhidao
The construction of Qin Zhidao is a very significant thing. It not only connects different regions, makes communication more frequent between people, and promotes integration of customs and habits in different regions;
Besides, it can better help Qin Shi Huang govern different regions and can report decisions to different places faster, increasing speed of information dissemination;
This road is also useful for ethnic integration. People of different nationalities from different regions can travel along this road to other places, get acquainted with the folk customs of other places, and communicate more closely with other places. , gradually some people moved to other places, and mixed marriages between different ethnic groups began, which contributed to social stability and ethnic unity;
It can also help our country develop its economy better. There are more and more merchants and some people prefer to do business. Delicacies from different regions appear in different places. A great vitality flared up.
In our impression, roads in ancient times were very narrow and rugged, and horse-drawn carriage constantly shook when walking along road, and due to narrowness of road, only one carriage could move forward in time. But in fact, Qin Zhidao is not like that, Qin Zhidao is quite wide, and according to width of carriages in ancient times, if more than ten carriages are moving side by side at same time, it will not seem cramped and cramped. difficult to walk. Please see width of Qin Zhidao It is impossible to compare some of our existing expressways. And so far, not a single weed has grown on this road, and it has not been destroyed by natural disasters. It can be seen that although such materials did not exist before, human wisdom shone.
