Chapter 221 Small Cross Road Plan 2
The executive committee decided to focus the construction of the east-west road on the high mountains in the east, which is the Viya Mountains. Read the full text. First, build the road from the county seat to Damei Village. In the plan, the Piashan area will be used as the main breeding base of the Cross Group in the future. Taking advantage of the relatively cool climate in the mountainous area, local pastures will be opened to raise horses, goats, cattle, donkeys, mules and other livestock. At the same time, the cultivation of mountain economic crops 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 Viya Mountain. Store the respective materials and books owned by the Time Travel Group here.
As for the area west of Wenlan River. In addition to the Tianyang area along the river, the most valuable area is probably the Ma Niao area. As a salt-producing area, a salt export port and a future salt chemical industry base, the Bobu-Mahiao road seems to be more important. However, the amount of salt from the Mahiao Peninsula is now transported by sea ships and the transportation cost is low. The so-called Shan Daoqian believes that for the time being There is no need to open this road.
"However, if we want to open it, we can do something that will kill 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 arterial roads in Lingao, but few people pass through this post road. Especially on the road to Danzhou, there was no material exchange between Lingao and Danzhou in the Ming Dynasty. The only bulk cargo transportation was the official and military pay from Lingao to Danzhou. Every year, two yuan of the autumn tax was allocated. More than a thousand stones of grain were shipped to Danzhou. To be on the safe side, always go overland. As for the road to Fucheng, there are more people. However, the road conditions along the way are poor, so most people still choose to take the sea route.
Shan Daoqian once explored these two official roads on the spot. The condition of the road is very poor, so bad that it can only be regarded as an ungraded road. The narrowest part is only two meters wide, and the widest part is less than four meters. It is just the most ordinary dirt road. 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 road even turns into a creek. 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 subsidence. It is said that "the road has become a river after many years." This kind of dirt road has no roadbed and no drainage, so 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 nothing more than tinkering, without much substantial change - no wonder someone said that changes in ancient life were extremely slow.
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 with a large population of villages. After passing Jiasui Pu, the last ten miles of the road leading to Chengmai, both sides of the road It is completely 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. They are responsible for delivering documents, maintaining supplies when official personnel pass through, and maintaining the road.
"Building the official road is certainly good to please Wu Mingjin, but it is of little benefit to us." Wen Desi looked at the road 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, so I'll just renovate part of it - starting from the west gate of the county and ending at Chaoyang Pu." Chaoyangpu belongs to Bobei Town on the modern Lingao map, 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 is definitely happy. The quality of traffic on the county's post roads is also the basis for his political performance evaluation."
"As for the other sections of road," said Xi Yazhou, who is responsible for assessing the military significance of the road project, "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 is responsible for is to carry out comprehensive road hardening of existing roads. He immediately encountered a problem: insufficient hardening material.
The hardened materials used in road construction by the Crossing Group are mainly coal slag and steel slag. Recently, after it was discovered that steel slag could be used to make phosphate fertilizer, it was taken over by the agricultural department, leaving Shan Daoqian with only coal slag. In fact, even if steel slag is added, it is only a drop in the bucket of this huge plan.
Not only are there insufficient hardened materials, but the road surface that has been hardened with cinders has also exposed the problem of weak pressure resistance. Heavy-duty oxcarts with hardwood wheels have caused 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 it is not repaired, 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. Said later.
"Gravel road, you might as well say asphalt road." Merlin disagreed. Gravel road is naturally better than a layer of cinder on dirt road, but where can we find so much gravel?
Stone, they have it. 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-end building stones. Nanbao Mining Office mainly uses blasting to mine stone materials on a large scale, but the roadbed is mainly filled with 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 road."
"Of course we can't continue to do manual labor. Mass movement can save us for a while, but it can't save us forever. Do I want to ask the mineral processing plant for help?" Shan Daoqian sat down on the mileage stone, "The mineral processing plant has two crushers. Block breaking is more than enough.”
"The machine is very busy now. The cement plant, fuel plant, and ceramics plant have to work day and night to crush it. I'm afraid it will be too late to be responsible for road construction stones. The iron ore has not come yet, but there will be iron ore in the future. Stone is worse.”
"It would be best if I could have one myself." Shan Daoqian thought for a moment, "Apply to the Planning Commission and let the machinery factory make one. How about putting it in Nanbao's quarry and processing the gravel directly? Then transport it out and use it.”
"I wonder. Have you seen the crusher?"
"It's a very simple machine. Just build the simplest single toggle plate jaw crusher. How difficult is it?"
The main component of this type of jaw crusher is an eccentric wheel that drives 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 simple enough for elementary school students to understand, and it works very reliably, requiring 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's a waste of materials."
Although this kind of crusher has various advantages, it is bulky and thick. It is basically made of steel. One movable jaw plate uses more than one ton of steel. It is very questionable whether this large consumer of steel 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. The Nanbao Mining Office also mentioned to the Planning Commission that it would be best to build a local mineral processing plant to sort and crush the various ores mined locally to save transportation capacity.
Ma Qianzhu not only approved the crusher, but also added that once it is successfully manufactured, three more will be manufactured. All four machines are used in Nanbao mineral processing plant. In addition, a Mozi Type 1 steam engine was allocated to drive the equipment.
The machinery factory, which had just recently equipped its forging workshop, became 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 fetish", and everything is bigger, the better. When talking about big things like hydraulic presses and forging machines, they all seem to be talking about a certain AV actress with a nice face, a good body, and a seductive voice.
The main component of the crusher is the jaw plate, which can be made of mild steel. Through the manufacture of cast guns, steam engine cylinders and other large equipment, the metallurgical department now has considerable experience in the casting of large castings. Several apprentices brought out by Xiao Bailang can already help make molds for large castings. The jaw plate weighs about a ton and is far from the heaviest casting they have ever made.
Soon, the foundry poured the required steel billets. 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 machine factory.
Now the jaw plate ingot is still as cast, and should have larger columnar crystals and a loose center. 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 loosen and compact them in order to obtain excellent metal structure and mechanical properties. ,.
