Papermaking is destined to be just Chen Ying's wishful thinking. I don't know if I don't do it, and I'm shocked when I do it. Chen Ying asked hundreds of craftsmen in a row, not to mention papermaking, they had never even heard of it. With a little manufacturing process that Chen Yingdao got from hearsay, God knows that the Year of the Monkey can only make paper?

Unless Chen Ying can dig up a large number of skilled craftsmen from the rice paper workshop, but the idea is just for thought. In this era, it is not as good as in later generations, because now you can buy and buy the population, like the shade and tenants are inherited from generation to generation, these core personnel can't dig at all, even if they pry the corners of the wall, the price will not be small.

What's more, Chen Ying doesn't have this time. 、

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

Chen Ying originally thought that it would be very easy to dig a ditch with a length of nearly seventy miles, but more than 500 people moved up and down, and the big guy was worthy of the money and food he gave, but the progress, except for the first few days, a trench with a length of more than 500 steps was dug, but in recent days, the progress has become slower and slower.

Chen Ying was displeased, he thought that these people were passive and slacking off, but when he came to the scene of digging the ditch, he suddenly felt confused. These craftsmen don't need to be supervised at all, the sweat of digging is like rain, and the sweat of pulling soil is also like rain, but they are never fast. I thought about it for a long time, but I still didn't figure it out.

When Chen Ying calmed down and calculated, he realized that he was still too eye-catching. Because this ditch is not simply convenient for irrigation, but also to undertake transportation, so the width design is 12 zhang 6 feet (about 29.61 meters) deep and 2 zhang, the bottom is 6 zhang 6 feet wide (about equal to 15.51 meters), the area of the entire ditch is 1006 square meters, every time you dig one meter forward, you need to dig out 106 cubic meters, and the whole project needs to dig out 3.71 million cubic meters.

In later generations, such a project was only pediatric, and all kinds of machinery were put into battle, and it could be completed in more than a month at most. But in this era, such a volume of work is simply desperate.

Even if it takes 500 people to dig the soil, but each person has to dig out more than 7,004 square meters, even if each person keeps digging the soil every day, the amount of work of ten cubic meters has reached the sky. At this time, the main mode of transportation is the deer cart, in fact, to put it bluntly, it is a wooden wheelbarrow, a cart is two or three hundred pounds......

It's not that these craftsmen don't do their best, but the amount of work is too much, beyond their limits. A hundred deer carts kept transporting, running more than 100 back and forth in six hours (at this time digging to the place where the soil was unloaded was very close), according to the calculation of 300 catties per cart, only 3 million catties of soil could be transported in a day. The density of the soil is 1.2, more than 3 million catties sounds like a lot, but in fact it is more than 1,000 cubic meters. In other words, it is only the amount of excavation that has been excavated twelve meters forward from the ditch.

Finding this problem, Chen Ying found Ge Tong and told Ge Tong bluntly: "The progress of these people is too slow, and at the current rate, I am afraid that this ditch will not be dug well in ten years." Now the speed that restricts the speed of digging ditches is the speed at which the soil is transported, do you have a better way? ”

"This ......" Ge Tong was stopped by Chen Ying instead, he scratched his head, and said puzzledly: "Isn't it all like this?" What better way? ”

Chen Ying secretly sighed in his heart, he really missed the future generations, a heavy-duty truck can pull thirty or fifty cubic meters, like such a close distance, ten dump trucks a day, easily complete tens of thousands of cubic meters of transportation work. The best of land transportation is still trains, calculated by standard carriages transporting coal, each carriage carries 40 tons, and an open-top train can pull 40 trains, which is 16,000 tons.

"Trains". A flash of inspiration flashed in Chen Ying's head, although in this era, it was almost impossible to build a steam train. However, Chen Ying thought of the galloping road as early as the pre-Qin era. The Chidao built during the Qin Dynasty, when the Qin Dynasty destroyed Chu, mobilized 600,000 troops, plus the materials consumed by the soldiers and civilians every day, it will be a massive number, with the transportation capacity at that time, it is almost impossible to do such a task.

For this reason, the Qin Dynasty began to build the gallop road, the Qin Dynasty's gallop road and the later generations of rails, the principle is the same, the only difference is that the track on the Qin Dynasty gallop road is also made of wood, and the distance between the sleepers is exactly in sync with the horse's steps. Once the horse pulls the cart onto the track, it involuntarily "self-oscillates", and it is impossible not to run fast and almost stop.

Chen Ying's chaotic head gradually became clearer. Directly use the embankment of the ditch, along the embankment to build a duplex road in the north and south, when digging the channel, it can be used to transport the excavated soil, and after the ditch is completed, it can be connected with the official road of Datang to form a road transportation network.

Thinking of this, Chen Ying said excitedly: "Deputy Metropolitan Supervisor Ge, do you know the galloping road of the pre-Qin era? ”

When Ge Tong heard this, he was slightly stunned: "Qin Chi said, Xiao Lao'er has naturally heard it, in the early years, Xiao Lao'er also made a ...... for Chang'er in the yard to play with."

Speaking of this, Ge Tong remembered his son who died young. However, his heart was shocked: "Doesn't Grandpa want to build a Qin Chi Road?" This can't be repaired, the cost is too high, build a gallop road to Chang'an, and almost build another Chenjiabao! ”

Chen Ying thought to himself that this Ge Tong still had some knowledge in the end, but he knew that Chi Dao was good. Chen Ying analyzed the problem to Ge Tong: "Now, the speed at which we build ditches and dock forts is too slow, and we will need to purchase a large number of stones, iron ore, and coal in the future, these things are very large, if you don't solve the transportation problem, let alone make money, only the transportation cost will give me a headache, so Xiuchi Road must be repaired!" ”

Ge Tong naturally understands the truth, but as Chen Ying said, the lesser of two evils, although it costs money to repair Chi Road, but if you don't build Chi Road, it will be more wasteful to use traditional transportation methods.

More than 200 people who were transporting mud and wood immediately found that the steward had told them to stop transporting soil to Chenjiabao and spread the soil dug out of the ditch on the embankment on both sides of the ditch. In this way, their workload has been greatly reduced.

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

The wet mud was spread on the embankment, and they were tamped 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 proportion, and the three-foot three-foot soil is paved on the road surface, and after the three-foot three-foot three-piece soil is tamped, the carpenter will cut down the trees and process them into sleepers, which will be fixed on the pavement.

Sleepers naturally cannot be processed directly with wet wood, and it is best to use dry wood in the shade. Chen Ying naturally does not have so much shade dry wood, but Chen Ying knows that he can use the drying room and charcoal fire to quickly dry the wood to remove the moisture of the wood itself, but it does not affect the use of wood.

The track of Qinchi Road, which is slightly different from the later train tracks, is concave rather than convex on the rails of later generations. In this way, the wheels that enter the road are stuck in the grooves. You don't need a skilled driver, even if you don't know how to drive, you can drive a horse or an ox and gallop down the road.
