Without obstacles, the road construction is like a sharp arrow that has been unsheathed without any obstacles, and the equipment department distilled those raw asphalt from the petroleum through the guidance of the students of the Wenzheng School. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Of course, the most primitive method has to be executed with the most primitive tools.

Sun Qi doesn't have that level now, and he can't unlock higher-level drawings, such as asphalt mixers and asphalt pavers, with these two things, building roads is as simple as eating and drinking.

When the asphalt paver is operating, the front push rollers of the paver push the rear wheels forward and accept the asphalt fuel. The asphalt mixture discharged in the hopper is sent to the paving chamber by two independently driven scraper conveyors on the left and right sides of the bottom of the hopper, and the feeding volume is controlled by the two gates on the left and right of the rear bucket wall respectively. The auger paver has two spirals, left and right, and paves the material evenly to the left and right sides at the same time, but can also be driven independently of the left and right. As the paver moves forward, the asphalt paved on the ground is compacted and ironed, and the pavement is preliminarily compacted and leveled according to a certain width, thickness and camber.

And now, only the road surface is flattened manually with a flat shovel, and the work efficiency is very low.

This kind of machine can completely reduce human labor, but after the formal mechanic, this kind of machine can be unlocked. Jin Shi must have been shocked that road repair is not a problem.

Poured a formal mechanic, with the assistance of the above two machines, and now....

It's embarrassing to have only a few large pressure cookers and steam engines to take care of the work.

"Wen Zhong, glass cups and stills like this will be made more in the future, maybe we can use them when we drink."

Asphalt can be figured out, thanks to Sun Qi unlocked a pressure cooker drawing when considering the accommodation of everyone a few days ago, this is not a pressure cooker that can only steam rice stewed ribs for a few people, this is a super-large pressure cooker that can solve dozens of rations, almost as high as a two-person Of course, Zhang Wenzhong agreed, and now that he thinks about it, he actually asked the members of the instrument division to use the small still and glass to divert the asphalt, which is really funny.

"Yes, yes, we listen to you, use that pot to separate the asphalt, and we will never use these little glasses to separate it again, otherwise we will not be able to finish the road construction task before the beginning of February."

This answer made Sun Qi cry and laugh, although he used this oversized pressure cooker to divert asphalt, but it was also a last resort, the industrial use of diverters and glasses is the best way to refine and purify asphalt, but unfortunately it cannot be mass-produced, only suitable for small-scale experimental use, forced to use no large-scale fractionator and asphalt production furnace, this time had to use the high-pressure rice cooker to fractionate asphalt.

"Asphalt has the highest burning point, and if you add firewood to it, it will not be asphalt, but something else."

Sun Qi is holding a book of "Chemical Industry Basics", which is about some simple fractionation methods for chemical purification, some equipment, Sun Qi, a science man in his previous life, has also touched, but there are no drawings, remember a little rough structure, can not completely get out, can only wait for the level of the mechanic to continue to improve, in order to slowly solve those high-grade drawings, now, slowly step by step, if you are too anxious, you will inevitably lift a stone and hit your own feet, undesirable, also ridiculous.

The above theory, Sun Qi is not proficient, just copy those chemical processes, asphalt is deeply hidden in the oil, the boiling point under reduced pressure or atmospheric pressure is not the same, at least 250 degrees to 330 degrees of temperature range, there is a great accuracy for the purification of asphalt, the equipment division at the beginning, some other purified substances mixed as asphalt, produced some bad effects, fortunately Sun Qi found this mistake in time, because according to common sense, asphalt can be distinguished by the naked eye, The asphalt extracted from petroleum is black and shiny, and the temperature sensitivity is very good.

"It would be nice if there was an asphalt purification tower, there was no need to be so troublesome, and the waste could be directly stripped and extracted, and the result was pure asphalt."

Sun Qi said asphalt purification tower, is the tower body is divided into the washing chamber that is located at the upper part of the tower body and the evaporation chamber that is located at the lower part of the tower body, the outside surface of described evaporation chamber is wrapped with several layers or a layer of insulation layer, the outer wall surface of the evaporation chamber and the insulation layer enclose the steam chamber, just like a huge output cavity, the steam chamber is like a shadow with the two standard configurations of steam inlet and steam outlet, and the evaporation chamber is just provided with the asphalt outflow pipe that communicates with the outside. When working, water vapor or heat transfer oil with a temperature of more than 130 degrees is introduced into the steam chamber, at this time, the water vapor and solvent oil are basically all evaporated, and the asphalt becomes a liquid and flows out along the asphalt outflow pipe. It solves the problem of insufficient purity of asphalt produced by ordinary methods and inconvenient operation due to asphalt hardening.

It's a pity that Sun Qi doesn't have this ability now, and beckons to Zhang Wenzhong from afar, the batch of iron ore in Jingzhou should arrive at the dock today, although Sun Qi hates Yangjia Wharf to the core, because this place has plundered too much Jiangning's resources, but sometimes he still has to overcome his inner resistance.

Slightly put down the work of the road repair team, Sun Qi and Zhang Wenzhong came to the riverside with a few guards, the wind was gusting, although the temperature was not cold, but the wind was very strong, blowing off the masts of the riverside civilian boats several, Jiangning's civilian boats generally do not come here, and those who can come here are only organizations that communicate with the government and local clans.

"How? Haodong? In the past few days, there have been no suspicious characters on this dock, right? ”

Liu Haodong was ordered by Sun Qi to garrison troops to protect the entire route from Jiangning County to Yangjia Wharf, especially Yangjia Wharf, which is a treasure of feng shui, before investigating and dealing with the Yang family, if it were not for Sun Qi's carefulness, he would not be able to find a hidden wharf, who could have known that the Yang family could hide so deeply, but now it is good, Sun Qi sent people to change all the wharves into civilian wharves, and now it is as lively as a bazaar.

From a distance, I saw Liu Haodong holding a green and immature plum in his hand, bargaining with an old farmer selling vegetables on the dock, although the temperature here is low, but it makes people feel that the temperature is not low, and it is a little stuffy.

"Well, my lord, there have been a lot of people and horses who have stepped on the white camp near the dock, and in recent days, I have really found a lot of suspicious people, but in a hurry, I can't catch a few tongues."

"Well, catch, catch a few tongues, and see what the idea is."

The wind blew and the flowers fell, and in the noisy buying and selling, several ships that looked like Jingzhong were slowly sailing along this wave belt towards the dock.
