Chapter 430 Little Cross Road Project ([-])

The executive committee decided to focus on the construction of east-west roads on the high mountains in the east, that is, the Piya Mountains.Firstly, build the highway from the county seat to Damei Village.According to the plan, the Biye Mountain area will be used as the main breeding base of the Crossing Group in the future. Taking advantage of the relatively cool climate in the mountainous area, we will open up pastures locally and raise various livestock such as horses, goats, cows, donkeys and mules.At the same time, the cultivation of economic crops in mountainous areas will be carried out.

At the same time, the key project "big library" and various scientific research facilities will be built in the core area of ​​Mt.Store the respective materials and books owned by the time travel group here.

As for the area west of the Wenlan River.Apart from Tianyang along the river, the most valuable area should be the Ma Niao area.As a salt production area, a salt export port and a future salt chemical base, the road between Bopu and Mayiao seems to be more important, but now the salt in the Maniao Peninsula is transported by sea ships with a large volume and low transportation costs. The so-called Shan Daoqian believes that for the time being There is no need to open this path.

"However, if we want to open it, we can do something 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, which is to renovate the post road - the official road.

Lingao's official road is basically along the coast.One starts from the east gate of the county, passes through Guanrongpu-Chaoyangpu-Changchuanpu-Jiasuipu, and then enters Chengmai County, which leads to Fucheng.The other one starts from Ximen and leads to Danzhou through Xinxingpu-Huaiyinpu-Luoxianpu.

These two are the main east-west roads of Lingao, but few people pass this post road.Especially on the road to Danzhou, there was no exchange of materials between Lingao and Danzhou in the Ming Dynasty. The only bulk cargo transportation was Lingao’s payment to Danzhou’s officers and soldiers. Duoshi grain was shipped to Danzhou.To be on the safe side, always go overland.As for the road to Fucheng, there are more people walking.However, the road conditions along the way are poor, so most people still choose to take the sea route.

Shan Daoqian once surveyed these two official roads on the spot.The state of the road is very poor, so bad that it can only be regarded as an unclassified road.The narrowest part is only two meters wide, and the widest part is less than four meters. It is just the most common dirt road.Not only is there no drainage, roadbed and other facilities, some places are even trench-like roads that sink into the ground, with an average of one meter below the ground, and some places are 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 traces of officialdom in many areas.

Shan Daoqian is not surprised by this - he learned a little about the history of Chinese road traffic when he was studying road construction, and he knew that ancient roads often had such road surface subsidence.This kind of dirt road has no subgrade and no drainage, so it will naturally become a "road ditch" over time.

The age of this road is very long even in the Ming Dynasty, and it was built during the Shaoxing period of the Song Dynasty.After that, it was nothing more than tinkering, and not many substantive changes were made-no wonder someone said that the changes in ancient life were extremely slow.

As for the environment along the road, it can be called desolate. The first few stations after coming out of the west gate of the county are considered areas with many villages and dense population. It is completely wilderness, with few people and fields.However, the bridges along the road are still maintained, and there are poor shop soldiers stationed on the road with a small amount of money and food to survive. They are responsible for delivering documents, maintaining the supply of official personnel and maintaining the road when they pass.

"Cultivating the official road is naturally good for currying favor with Wu Mingjin, but it is of little benefit to us." Wen Desi looked at the road map, "There are no areas worth developing along the way."

"It can facilitate the travel of the villages along the way and attract them to Dongmen City. It can also attract people from nearby Chengmai and Danzhou to come to Gao."

"However, this involves 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 is necessary to renovate all, but only a part - from the west gate of the county to Chaoyang shop." Chaoyangpu belongs to Bobei Town on the modern Lingao map, and it is very close to Ma Niao.After this section of road is repaired, it can also be used when the road to Ma Niao is built in the future.

"Wu Mingjin would definitely be happy, and the quality of the traffic on the post roads in the county is also the basis for his performance evaluation."

"As for the other road sections," said Xi Yaya, who was in charge of assessing the military significance of the road project, "I think it's okay if the road conditions are bad. If the repairs are too good, if the Ming army comes to attack us by land, they will go too fast."

The task of the Transportation Bureau under the charge of Shan Daoqian is to carry out comprehensive road hardening on the existing roads.He immediately ran into a problem: not enough hardening material.

The hardened materials used for road construction in the crossing group are mainly coal slag and steel slag.Recently, after steel slag was discovered to be used as phosphate fertilizer, it was accepted by the agricultural department, and the only thing Shan Daoqian could use was coal slag.In fact, even adding steel slag is a drop in the bucket for this huge plan.

Not only is the hardened material insufficient, but the road surface that has been hardened with cinders has also exposed the problem that it is not strong enough to withstand pressure. The heavy-duty bullock carts with hardwood wheels have greatly damaged the road surface.

"We have to use gravel to build the roadbed. The more the car travels on such a compacted soil roadbed, the faster it will be damaged."

"There needs to be maintenance. I want to set up a maintenance team to maintain the road sections. As long as it is not repaired, any road repaired will be damaged." Shan Daoqian and Mei Lin from the construction company inspected the potholed road that was crushed by bullock carts. said later.

"Gravel road? You might as well talk about asphalt road." Merlin didn't think so. A gravel road is naturally better than a layer of cinders on a dirt road, but where can I find so much gravel?

Stones, they have it all.Since the opening of Nanbao Town, the supply of stones for general building materials of the Crossing Group mainly comes from the Nanbao area. The original quarry at Bairentan mainly produces high-grade building stones.The Nanbao Mining Office mainly uses the blasting method to mine stones on a large scale, but the roadbed is mainly filled with crushed stones.The stone must be processed and broken.

"Do you know how many gravels are needed to harden these roads?" Mei Lin said to Shan Daoqian, "If women are sent to break the stones like this, if the roads are completely hardened, it will take until the year of the monkey."

"Of course we can't continue to engage in manual labor. The mass movement can save the world for a while. Do I want to ask the mineral processing plant for help?" Shan Daoqian sat down on the milestone, "The mineral processing plant has 2 crushers. The piece broken is more than enough."

"Now the machine is very busy. It is used in cement plants, fuel plants, and ceramic plants... It is broken day and night, and it may be too late to be responsible for road construction stones--the iron mine has not yet come, and there will be in the future. Iron ore is even worse."

"It's better if I can have one myself." Shan Daoqian thought for a while, "How about applying to the Planning Commission and letting the machinery factory make one? Put it in Nanbao's quarry and process the crushed stone directly. It’s better to ship it out and use it.”

"I see Xuan. Have you seen the Crusher?"

"It's a very simple machine, let's build the simplest single-toggle jaw crusher. How difficult is it?"

The main part of this jaw crusher is an eccentric wheel that drives a set of connecting rods, and then pushes the movable jaw plate through the connecting rods to squeeze the stones, so as to achieve the purpose of breaking large stones into small stones.The structure is so simple that elementary school students can understand it, and it works very reliably, requiring little maintenance.Although it was invented in 1858, it has been 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. It's expensive."

Although this kind of crusher has various advantages, it is stupid and thick, and it is basically piled up with steel.A movable jaw plate requires more than one ton of steel. Whether this large steel consumer can obtain a manufacturing license from the Planning Commission is very problematic.

Unexpectedly, Ma Qianzhu readily agreed.Nowadays, there are more and more infrastructure constructions, and the demand for building materials is increasing day by day. Whether it is cement, lime, or crushed stone, crushers are needed.The Nanbao Mining Office also mentioned to the Planning Commission that it is best to build a concentrator locally to sort and crush the various ores mined locally to save transportation capacity.

Ma Qianju not only approved the crusher, but also added—once the manufacturing is successful, three more will be manufactured.These four machines are all used in Nanbao Concentrator.In addition, another Mozi-type steam engine was allocated to drive the equipment.

The machinery factory that had just completed the equipment for the forging workshop recently heard that such a big project was about to take place, and immediately became full of energy.Most people who work in machinery have a kind of "giant obsession", and everything is as big as possible.When it comes to hydraulic presses, forging machines and other big guys, they seem to be talking about some AV actress with a good face, a good figure, and a seductive voice.

The main part of the crusher is the jaw plate, which can be made of low carbon steel.Through the manufacture of cannons, steam engine cylinders and other large-scale equipment, the metallurgical department now has considerable experience in the casting of large-scale castings.The few apprentices brought out by Xiao Bailang are already able to help make the molds for large castings.The jaw plate weighs about a ton, far from the heaviest casting they've ever cast.

Soon, the foundry poured out the required billets.This one-ton steel billet was loaded onto a sixteen-wheeled heavy-duty rail car and pulled from the foundry all the way to the forging workshop of the machinery factory.

Now the jaw plate ingot is still as cast, and should have larger columnar crystals and loose centers.Limited mechanical strength.Therefore, large plastic deformation must be carried out through forging and heat treatment to break the columnar crystals into fine grains and loosen and compact them to obtain excellent metal structure and mechanical properties.
