The executive committee decided to focus the construction of east-west roads on the high mountains in the east, which is the Piashan District. First, the road from the county seat to Damei Village will be built. The Piashan area will be used as a route through the group in the future.
The main breeding base takes advantage of the relatively cool climate in the mountainous areas to open up pastures locally to raise horses, goats, cattle, donkeys, mules and other livestock. At the same time, it also carries out the cultivation of mountain cash crops.
At the same time, a key project "Great Library" and various scientific research facilities will be built in the core area of Mount Viya. The respective materials and books owned by the Travel Group will be stored 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 industry base, the Bopu-Ma Niao road seems to be more
Important, but now that the salt from Mayao Peninsula is transported by sea ships in large quantities and the transportation cost is low, Shan Daoqian believes that there is no need to open this road for the time being.
"However, if it is to be opened, we can do something that kills two birds with one stone." Shan Daoqian reported to the executive committee, "it may be good for Xiong Buyou's work."
Shan Daoqian's idea is very simple, which is to renovate the post road - the official road.
The official roads in Lingao are 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 the west gate and leads to Danzhou through Xingxingpu-Huaiyinpu-Luoxianpu.
These two are the main east-west trunk roads in Lingao, but few people pass through this post road. Especially the road to Danzhou. In the Ming Dynasty, there was no material exchange between Lingao and Danzhou. The only bulk cargo transportation
That is, Lingao pays the officers and soldiers of Danzhou, and every year more than 2,000 shi of grain are allocated from the autumn tax to Danzhou. For the sake of safety, they always take the land route. As for the road to Fucheng, it is necessary for people to take it.
More. 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 condition of the roads is very poor, so bad that it can only be regarded as an ungraded road. The width is only two meters at the narrowest point and less than four meters at the widest point. It is the most ordinary dirt road.
That’s it. Not only are there no facilities such as drainage and roadbed, but in some places there are even trench-like roads that sink into the ground, with an average of one meter below the ground and as low as four meters in some places. When it rains, the roads even become small rivers.
.If it were not for the guidance of local guides, Shan Daoqian would not be able to distinguish traces of official roads in many areas.
Shan Daoqian is not surprised by this - when he was studying road construction, he learned a little bit about China's road traffic history and knew that ancient roads often had such surface subsidence. It is said that "years of road turns into a river." This kind of dirt road has no
If the roadbed is not drained, it will naturally become a "road ditch" over time.
This road is very old even in the Ming Dynasty. It was built during the Shaoxing period of the Song Dynasty. After that, it was just a patchwork without many substantial changes - no wonder someone said that the changes in ancient life were extremely
slowly.
As for the environment along the road, it can be described as desolate. The first few stops after coming out of the west gate of the county are still areas where the village population is concentrated. After passing Jiasuipu and the last ten miles of the road leading to Chengmai, both sides of the road
It is a complete wilderness, with very few people or fields. However, the bridges along the road are still maintained, and poor soldiers who barely survive with a small amount of money and food are stationed at various shops on the road, responsible for delivering documents and maintaining the passage time of official personnel.
supply and maintain roads.
"Building the official road is certainly good to please Wu Mingjin, but it is of little benefit to us." Wen Desi looked at the route map and said, "There are no areas worth developing along the way."
"It can facilitate the travel of villages along the way and attract them to Dongmen City. It can also attract people from nearby Chengmai and Danzhou to come to Gao."
"But this involves the inns along the way. This needs to be negotiated with the county government." Wen Desi looked at the map and said, "I don't think it's necessary to renovate all of it, but just a part of it - starting from the west gate of the county and ending at Chaoyangpu."
Chaoyangpu, which belongs to Bobei Town on the modern Lingao map, is very close to Ma Niao. After this section of road is repaired, it can also be used when the road to M Niao is built in the future.
"Wu Mingjin is definitely happy. The quality of traffic on the county's post roads is also the basis for his political performance evaluation."
"As for other sections of road," said Xi Yazhou, who is responsible for assessing the military significance of road projects, "I think the road condition is not bad at all. If the road condition is too good, the Ming army will go too fast if they attack us by land."
The task of the Transportation Bureau that Shan Daoqian was in charge of was to comprehensively harden existing roads. He immediately encountered a problem: insufficient hardening materials.
The hardened materials used by the Crossing Group for road construction are mainly coal slag and steel slag. Recently, after it was discovered that steel slag can be used to make phosphate fertilizer, it has been taken over by the agricultural department. The only coal slag Shan Daoqian can use is. In fact, even if it is added
Steel slag is just a drop in the bucket in this huge plan.
Not only are there insufficient hardened materials, but the road surface that has been hardened with cinders also exposes the problem of weak pressure resistance. Heavy-duty oxcarts with hardwood wheels cause great damage to the road surface.
"You have to use gravel to build the roadbed. The more cars travel on this compacted soil roadbed, the faster it will be damaged."
"If there is maintenance, I will set up a maintenance class to maintain the road sections. If we don't repair it, any road that is repaired will be damaged." Mei Lin from Shandao Qianhe Construction Company inspected the road that was bumpy and bumpy by bullock carts.
Say it later.
"Gravel road? You might as well say asphalt road." Merlin disagreed. A gravel road is naturally better than a layer of cinder on a dirt road, but where can you find so much gravel?
They have plenty of stones. Since the opening of Nanbao Town, Chuanchuan Group's supply of general building materials has mainly come from the Nanbao area. The original Bairentan quarry mainly produced high-grade building stones.
Nanbao Mining Office mainly uses blasting to quarry stone on a large scale, but the roadbed mainly uses gravel. The stone must be processed and broken.
"Do you know how much gravel is needed to harden these roads?" Mei Lin said to Shan Daoqian, "If we send women to work as we do now to knock stones, it will take until the year of the monkey to fully harden the roads."
"Of course we can't continue to do manual labor. Mass movement can save us for a while but not forever. Do I want to ask the mineral processing plant for help?" Shan Daoqian sat down on the mile stone, "The mineral processing plant has two crushers. The mineral processing plant has two crushers.
Block breaking is more than enough.”
"The machine is very busy now. It is used in cement plants, fuel plants, and ceramics plants... It is crushing day and night. I am afraid it will be too late to be responsible for road construction stones. The iron ore has not come yet, but it will come later.
Iron ore is even worse."
"It would be best if I could have one myself." Shan Daoqian thought for a moment, "How about applying to the Planning Commission and letting the machinery factory make one? Just put it in Nanbao's quarry and process the gravel directly.
It’s good to transport it out and use it later.”
"I see. Have you seen the crusher?"
"It's a very simple machine, just build the simplest single toggle plate jaw crusher. How difficult is this?"
The main component of this kind of jaw crusher is an eccentric wheel driving a set of connecting rods, and then the connecting rods push the movable jaw plate to squeeze the stone, thereby achieving the purpose of breaking large stones into small stones. The structure is as simple as a primary school student
It is also clear that it works very reliably and requires almost no 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.
"This is a steel tiger with a mouth full of steel teeth. It wastes materials."
Although this kind of crusher has many advantages, it is big and thick and is basically made of steel. One movable jaw plate uses more than a ton of steel. It is very problematic whether this large steel consumer can obtain the manufacturing license from the Planning Commission.
.
Unexpectedly, Ma Qianzhu approved it very quickly. 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 gravel, crushers are needed. Nanbao Mining Office also cooperates with
The Planning Commission mentioned that it would be best to build a local mineral processing plant to sort and crush the various mined ores locally to save transportation capacity.
Ma Qianzhu not only approved the crusher, but also added that once it is successfully manufactured, three more machines will be manufactured. All four machines will be used in Nanbao Mineral Processing Plant. In addition, a Mozi-1 steam engine will be allocated for use.
drive equipment.
The machinery factory that had recently equipped its forging workshop was immediately energized when it heard that it was going to embark on such a big project. Most people who work on machinery have a kind of "giant addiction", and the bigger the better in everything. When it comes to hydraulic presses
, forging machines and other big guys, they all seem to be talking about a certain AV actress with a good face, a good body, and a seductive voice.
The main component of the crusher is the jaw plate, which can be made of low carbon steel. Through the manufacturing of cannons, steam engine cylinders and other large equipment, the metallurgical department now has considerable experience in the casting of large castings. Xiao Bailang brought it out
Several of his apprentices can already help make molds for large castings. This jaw plate weighs about 1 ton, which is far from the heaviest casting they have ever cast.
Soon, the foundry poured the required steel billet. The one-ton billet was loaded onto a sixteen-wheel heavy-duty rail car and hauled from the foundry to the forging workshop of the machinery plant.
Now the jaw plate ingot is still as cast, with larger columnar crystals and a loose center. The mechanical strength is limited. Therefore, large plastic deformation must be carried out through forging and heat treatment to break the columnar crystals into fine grains.
Only by loosening and compacting can we obtain excellent metal structure and mechanical properties.
