The decision of the Executive Committee focused on the construction of the east-west road on the eastern high mountain range, which is the Viye Mountains. First of all, the road from the county seat to Damei Village was built. In the planning, the Viye Mountain area will be used as the main breeding base of the future crossing group, taking advantage of the relatively cool climate in the mountainous area, opening up pastures in the local area to raise horses, goats, cattle, donkeys and mules and other livestock. At the same time, the cultivation of mountain cash crops was carried out.

At the same time, the construction of the key project "Great Library" and various scientific research facilities in the core area of the Viya Mountains. The materials and books owned by the crossing group are stored here.

As for the area west of the Wenlan River. In addition to the fields along the river, the most valuable area should be the Mayuan area. As a salt producing area, a salt export port and a future salt chemical base, the Bopu-Mayuan road seems to be more important, but now the salt on the Mayuan Peninsula is transported by sea ships in large quantities and at low transportation costs, and the so-called Shan Daoqian believes that there is no need to open this road for the time being.

"However, if we want to open it, we can do one thing that kills two birds with one stone." Shan Daoqian reported to the Executive Committee, "It may be beneficial to Xiong Buyou's work. ”

Shan Daoqian's idea is very simple, that is, to renovate the post road - the official road.

The official road of Lingao is basically coastal. One is from the east gate of the county, through Guanrongpu - Chaoyang Pu - Changchuan Pu - Jiasui Pu, and then enter the territory of Chengmai County, which leads to the Fucheng. The other one starts from the West Gate and leads to Danzhou through Xinxingpu - Huaiyin Pu - Luoxianpu.

These two are the main east-west roads of Lingao, but this post road is rarely passed. Especially the road to Danzhou, there is no material exchange between Lingao and Danzhou in the Ming Dynasty, and the only bulk cargo transportation is Lingao to Danzhou's official and military co-pay, and more than 2,000 stone of grain will be allocated to Danzhou every year. Always go overland to be on the safe side. As for the road to Fucheng, there are more people. However, the road conditions along the way are bad, so most people still choose to take the sea route.

Shan Daoqian once explored these two official roads on the spot. The state of the road is very poor, so bad that it can only be regarded as a non-grade road. The width is only two meters at its narrowest point, and less than four meters at its widest point, and it is just the most ordinary dirt road. Not only are there no facilities such as drainage and roadbed, but in some places they are simply trenched roads that sink into the ground, with an average of one meter below the ground, and in some places as low as four meters. When it rains, the road even becomes a small river. If it weren't for the guidance of local guides, Shan Daoqian would not be able to distinguish the traces of official roads in many areas.

Shan Daoqian is not surprised by this -- he learned a little about the history of China's road traffic when he was studying road construction, and he knew that ancient roads often had such a situation of road surface subsidence, the so-called "many years of road into a river". This kind of dirt road has no roadbed and no drainage, and it will naturally become a "ditch" state over time.

The age of this road is a long time ago even in the Ming Dynasty, and it was built during the Shaoxing period of the Song Dynasty. After that, it was just tinkering, and little real change was made - no wonder it was said that life in ancient times changed very slowly.

As for the environment along the road, it can be called the word desolate, the first few stops after the county west gate comes out are still considered to be the area where the village is multi-populated, and when it comes to the zuihou more than ten miles of road leading to Chengmai after passing the Jiasui shop, both sides of the road are completely wilderness, and it is rare to see people and fields. However, the bridges along the road were still maintained, and the poor pavements on the road, as well as Kao, barely survived with a small amount of money and food, were stationed to deliver documents, maintain supplies for official personnel, and maintain the road.

"Cultivating the official road is naturally good for currying favor with Wu Mingjin, but it is not good for us." Wen Deji looked at the road map, "There are not many areas worth developing along the way. ”

"It can be convenient for the villages along the way to travel and attract them to Dongmen City. It can also attract the people of Chengmai and Danzhou, who are close to the city. ”

"But that's where it comes to the post shops along the way. This needs to be negotiated with the county government. Wen Desi looked at the map, "I don't think it's necessary to renovate it all, just repair part of it - starting from the west gate of the county to Chaoyangpu." "Chaoyangpu, on the map of modern Lingao, belongs to Bobei Town, very close to Ma Yuan. After this section of the road is repaired, it can be used to build the road to Mayuan in the future.

"Wu Mingjin is definitely willing, and the quality of the post road traffic in the county is also the basis for his performance evaluation."

"As for the other sections," said Xi Yaya, who was in charge of assessing the military significance of the road works, "I think it's not bad if the road is in bad condition, but if the Ming army comes to attack us by land, it will be too fast." ”

The task of the Transportation Bureau, which is under the responsibility of Shan Daoqian, is to carry out comprehensive road hardening of existing roads. He immediately encountered a problem: there was not enough hardening material.

The hardened materials used in road construction are mainly cinders and steel slag. Recently, after steel slag was discovered to be used as phosphate fertilizer, it was taken over by the agricultural department, and only cinder was left to be used by Shan Daoqian. In fact, even if steel slag is added, it is a drop in the bucket for this huge jihua.

Not only is the hardened material insufficient, but the road surface that has been hardened with cinder has also caused the problem of low pressure resistance, and the heavy-duty ox cart with hardwood wheels has caused great damage to the road surface.

"You have to use gravel to build the roadbed, and after this kind of compacted earth roadbed, the more cars will go, and the faster it will be damaged."

"If you want to maintain, I want to have a maintenance class, and maintain it in different sections, just use it and don't repair it, and any road will be broken." Shan Daoqian and Merlin of the construction company said after patrolling the potholed roads that were crushed by ox carts.

"Gravel road? You might as well say asphalt roads. Merlin disagreed, gravel roads were naturally better than dirt roads with a layer of cinders, but where to find so much gravel?

Stones, they have to be. Since the opening of Nanbao Town, the supply of general building materials for the group has mainly come from the Nanbao area, and the original quarry of Bairentan is mainly used to manufacture high-grade building stones. The Nanbao Mining Department mainly uses the blasting method to mine stone on a large scale, but the landfill subgrade mainly uses gravel. The stone must be processed and crushed.

"Do you know how much gravel it takes to harden these pavements?" Merlin said to Shan Daoqian, "If Kao sends women to knock stones like this now, and the road is fully hardened, it will have to be knocked until the Year of the Monkey." ”

"Of course, we can't continue to do manual labor. The mass movement can save a lifetime but cannot save a lifetime. I'm trying to ask the concentrator for help? Shan Daoqian sat on the mile stone, "The concentrator has 2 crushers. It is more than enough to do stone breaking. ”

"Now the machine is very busy, and the cement plant, the fuel plant, and the ceramics factory all have to use it...... It's crushing day and night, and it's too late to be responsible for building the road and the stone -- the iron ore hasn't come yet, and it's even worse if there is iron ore in the future. ”

"It's best to have your own." Shan Daoqian thought for a while, "How about applying to the Planning Commission and letting the machinery factory make one?" Put it in the quarry of Nanbao, and directly process the crushed stone and then transport it out for use. ”

"I look at the hanging. Have you ever seen a crusher? ”

"It's a very simple machine, just build the simplest single-toggle jaw crusher. What's so difficult about it? ”

The main component of this jaw crusher is an eccentric wheel to drive a group of connecting rods, and then push the movable jaw plate to extrude the stone through the connecting rod, so as to achieve the purpose of crushing large stones into small stones. The structure is so simple that even elementary school students can understand it, and it is easy to work with, and it requires little maintenance. Although it was invented in 1858, it was used in cement, ceramics, mining, metallurgy and other industries until the second half of the 20th century.

"It's a steel tiger, full of steel teeth. Expensive. ”

Although this kind of crusher has all kinds of benefits, it is stupid and coarse, and it is basically stacked with steel. More than one ton of steel is required for a movable jaw plate, and it is very questionable whether this large steel consumer can obtain a manufacturing license from the Planning Commission.

Unexpectedly, Ma Qianzhu approved it very happily. Nowadays, there are more and more infrastructure construction, and the demand for building materials is increasing day by day, whether it is cement, lime, or gravel, crushers are needed. The Nanbao Mining Office also mentioned to the Planning Commission that it is best to build a concentrator plant in the local area, where the various ores mined can be sorted and crushed to save transportation capacity.

Ma Qianzhu not only approved the crusher, but also added - once the manufacturing is successful, three more will be manufactured. All four machines are used at the Nanbao concentrator. In addition, a Mozi Type 1 steam engine was allocated to drive the equipment.

Recently, the machinery factory that had just equipped the forging workshop with all the equipment heard that it was going to be such a big project, and it was immediately full of energy. Most people who work in machinery have a kind of "mega fetish", and the bigger the better. When it comes to big guys such as hydraulic presses and forging machines, it seems to be saying that a certain person has a good face, a good figure, and a tempting voice.

The main component of the crusher is the jaw plate, which can be made of mild steel. Through the manufacture of casting cannons, steam engine cylinders and other large-scale equipment, the metallurgical sector now has considerable experience in the casting of large castings. A few apprentices brought out by Xiao Bailang can already help make casting molds for large castings. The jaw plate weighed about 1 ton, far from the heaviest casting they had ever cast.

Soon, the foundry poured the required billets. The one-ton billet was loaded onto a sixteen-wheeled heavy-haul railcar and hauled from the foundry to the machine shop's forging shop.

At present, this jaw plate ingot is still a cast structure, and it should have large columnar crystals and loose centers. Limited mechanical strength. Therefore, it is necessary to carry out large plastic deformation through forging and heat treatment, break the columnar crystals into fine grains, and compact them loosely to obtain excellent metal structure and mechanical properties.
