Prosperous Tang Blood Blade

Chapter 321 Inspiration from the Train

Papermaking is destined to be just wishful thinking of Chen Ying.If you don’t do it, you don’t know. If you do it, you will be shocked.Chen Ying continuously asked hundreds of craftsmen, let alone papermaking, they had never even heard of it.Based on Chen Yingdao's hearsay of a little manufacturing process, God knows that paper can only be made in a year of the monkey?

Unless Chen Ying can recruit a large number of skilled craftsmen from the rice paper workshop, but this idea is just a thought.This era is no better than later generations, because people can be bought and bought now, such as shade households and tenant tenants are inherited from generation to generation, these core personnel cannot be dug out at all, even if they pry the corners, the price will not be small.

What's more, Chen Ying didn't have the time either. ,

Putting his whimsical thoughts out of his mind, Chen Ying went to the construction site to inspect.

Chen Ying originally thought that it would be very easy to dig a ditch with a length of nearly [-] miles, but more than [-] people moved up and down. A trench with a length of more than [-] steps, but in recent days, the progress has been getting slower and slower.

Chen Ying was displeased. He thought that these peasants were passive and sabotage, but when he came to the canal digging site, he felt confused.These folk craftsmen don't need to be urged at all. Those who dig the soil are sweating like rain, and those who pull the soil are also sweating like rain, but they still can't get up quickly.After thinking for a long time, I still haven't figured it out.

When Chen Ying calmed down to do some calculations, he realized that he was still too good at what he did.Since this ditch is not only convenient for irrigation, but also for transportation, the width is designed to be 29.61 feet 15.51 feet (about 370 meters) and [-] feet deep, and the bottom is [-] feet [-] feet (about [-] meters) wide. The area of ​​the entire ditch is It is [-] square meters. For every one meter forward, [-] cubic meters need to be dug out. After the whole project, [-] million cubic meters need to be dug out.

In later generations, this kind of project is just a child's work, and all kinds of machinery can be put into battle, and it can be completed in more than a month at most.But in this day and age, such an amount of engineering is simply hopeless.

Even if it takes 500 people to dig the soil, each person has to dig out more than [-] square meters. Even if each person keeps digging every day, the engineering volume of ten cubic meters is already sky-high.But the transportation work is even more desperate. At this time, the main transportation method is a deer cart. In fact, it is a wooden wheelbarrow, and a cart weighs two to three hundred catties...

It's not that these folk craftsmen don't work hard, but that the amount of work is too much, which exceeds their limits.One hundred deer carts were transported non-stop, and they ran more than 100 round trips in six hours (at this time, the excavation site was very close to the place where the soil was unloaded). Based on the calculation of 300 jin per car, it can only transport 300 million yuan a day. kg of soil.The density of the soil is 1000. More than 12 million jin sounds like a lot, but in fact it is only more than [-] cubic meters.In other words, it is only the unearthed amount of [-] meters excavated from the ditch.

When Chen Ying found this problem, he approached Ge Tong and told Ge Tong bluntly: "The progress of these civilians is too slow. According to the current speed, I am afraid that this ditch will not be dug well in ten years. What restricts the speed of digging the ditch now is Do you have a better way to transport the dirt?"

"This..." Ge Tong was stopped by Chen Ying's question instead. He scratched his head and said puzzledly, "Isn't it always like this? Is there any better way?"

Chen Ying sighed secretly in his heart. He really missed the future generations. A heavy-duty truck can pull thirty to fifty cubic meters. For such a short distance, ten dump trucks can easily complete the transportation work of tens of thousands of cubic meters per day.The most powerful land transportation is the train. Calculated by the standard carriages for transporting coal, each carriage can carry [-] tons, and an open train can pull [-] trains, which is [-] tons.

"train".An idea flashed in Chen Ying's head, although in this era, it is almost impossible to build a steam train.However, Chen Ying thought of Chi Dao as early as the pre-Qin period.The Chidao built during the Qin Dynasty, when the Qin Dynasty destroyed Chu, used 60 troops, plus the soldiers who accompanied the army, the daily consumption of materials would be a huge number. With the transportation capacity at that time, it was almost impossible to do so. work tasks.

For this reason, the Qin Dynasty began to build galloping tracks. The principle of the Qin Dynasty’s galloping tracks was the same as that of later generations’ railroad tracks. The only difference was that the tracks on the Qin Dynasty’s galloping tracks were also made of wood, and the distance between the sleepers coincided with the horse’s steps. .Once the horse pulls the cart onto the track, it will involuntarily undergo "self-excited oscillation", and it has to run fast, and it is almost impossible to stop.

Chen Ying's confused mind gradually became clear.Directly use the embankment of the ditch, and build a double-type road along the embankment in the north and south. When digging the canal, it can be used to transport the excavated soil. After the ditches are completed, they can be connected with the official road of Datang to form a road. transport network.

Thinking of this, Chen Ying said excitedly: "Deputy Governor Ge, do you know Chi Dao in the pre-Qin period?"

Hearing this, Ge Tong was slightly taken aback: "Qin Chi said, the little old man has heard of it. In the early years, the little old man even made one in the yard for Chang'er to play with..."

Speaking of this, Ge Tong thought of his son who died young.However, he was shocked in his heart: "Grandfather, don't you want to build a Qinchi road? It can't be built, the cost is too high, and building a Chi road to Chang'an is almost like building another Chenjiabao!"

Chen Ying thought that this Ge Tong still had some knowledge, but it was good that he knew Chi Dao.Chen Ying analyzed the problem to Ge Tong: "Now, we are too slow in building ditches and docks. In the future, we will need to purchase a large amount of stone, iron ore, and coal. These things are very large. If we do not solve the problem of transportation Difficulties, not to mention making money, just the transportation cost will cause me a lot of headaches, so repairing Chidao is a must!"

Ge Tong naturally understands the truth, but as Chen Ying said, the two evils are the lesser of two evils. Although it costs money to build roads, it will be even more wasteful to use traditional transportation methods if they are not built.

More than [-] peasants transporting mud and wood suddenly realized that the steward told them to stop transporting mud to Chenjiabao, and instead spread the mud dug from the nearby ditch on the embankment on both sides of the ditch.In this way, their workload is greatly reduced.

However, they slowly discovered that the problem was not as simple as they imagined.

The wet mud was spread on the embankment, and they were asked to tamp it down one by one with wooden hammers to form a roadbed about six feet wide, but the work did not stop, but continued.The wet mud dug out of the ditch is mixed with lime and fine sand to form a specific ratio. This kind of compound soil is paved three feet on the road surface. After the three-foot compound soil is compacted, the carpenter will cut down the trees and process them into sleepers. , on a fixed road surface.

Naturally, wet wood cannot be used for sleepers, and it is better to use shade-dried wood for direct processing.Naturally, Chen Ying didn't have so much shade-dried wood, but Chen Ying knew that he could use a drying room to dry the wood quickly by using charcoal fire to remove the moisture of the wood itself, but it would not affect the use of the wood.

The track of Qin Chi Road, which is slightly different from the railway tracks of later generations, is concave instead of convex on the tracks of later generations.Enter the wheel in the raceway like this, be stuck in the groove.There is no need for a skilled driver at all, even if you don't know how to drive, you can drive horses or cattle to gallop on the galloping road.
