In fact, when he first arrived in Danzhou, President Meng had spent a lot of manpower on the road, and the foreign migrant workers found in Danzhou were mainly North Koreans, and there were also many locals in Northeast China.A few days later, the No. 1 blast furnace was finally completed and put into operation, with a daily output of 130 tons of iron, and the coke oven was put into operation, with a daily output of 440 tons of coke.This is very scary in this day and age.President Meng's hard work is not in vain Benxi front line bombing every day, President Meng in the rear efforts to develop, the start of the steel industry, will mark Danzhou's defense is more stable, Benxi front line bombing, but also continue to test the quality of Danzhou steel, many experimental shells have been taken to the front line.War is indeed the best medicine that can stimulate the development of production and make a leap forward in the level of science and technology.More than 30 industrial zones in Danzhou, President Meng's company, are concentrated near the port, forming an industrial zone group, and slogans and posters are posted everywhere in the industrial zone group, most of which are slogans such as throwing their heads and spilling blood to support the Great Patriotic War.Either it is to defend the leader and defend the motherland.Whoever dares to beat us, I will kill him.All walks of life are passionate, and the sound of daily bombardment is the best stimulation for the factory.With a total length of about 25 meters, the rails are not cheap and account for a fairly significant part of the railway cost.The rail section used in Danzhou is in the shape of a "work", which is divided into the rail head in contact with the wheel, the rail waist in the middle and the rail bottom at the bottom.Different routes have different requirements for the strength, stability and wear resistance of the rails.Therefore, the rails are also available in different specifications.The choice of which route should be used requires consideration of economic and technical factors.The type and strength of the rail are expressed in kg.The heavier the rail per metre, the greater the weight it can bear.Danzhou's rails are modeled after those of the United States, using 77 specifications.The rails are made of high manganese steel.The temper of manganese steel is very strange and interesting: if you add 23 manganese to the steel, the resulting low-manganese steel is as brittle as glass and will shatter when you knock it.However, if you add manganese from GT13 to make a high-manganese steel, it becomes both hard and tough.So people use manganese steel to make wear-resistant machine parts and railroad tracks, bridges, etc.Also, in the upper part of the rail, that is, the layer that is in contact with the wheel, another metal indium is added, and its addition makes the upper part of the rail more resilient under the condition of ensuring the hardness, which is very important for the wheels of the train, and when it contacts and collides with the "hoop", it will have a certain elasticity to ensure the safe operation of the train.There are several ways to connect rails into rails.The most traditional method is to fix a section of about 20 meters of steel rails on the sleeper, and there are joints between each section of the rail, also known as joints.In the UK, it is customary for two rails to have joints in the same place, but in the United States they are placed in different places.It was the Americans who helped build the railway in Danzhou, so many of the practices of the railway in Danzhou are in line with the United States.President Meng also has a consideration, that is, in order to pave the way for the future railway to connect with Tsarist Russia, in the construction of the railway, President Meng thought of this Although the Tsarist Russia is very large and far away, but President Meng's subconscious, has taken the Tsarist Russia as a goal, so many things, in the early days of the establishment, he has considered the matter of connecting with Tsarist Russia.The rail joint is joined using a fishtail plate, which is a steel plate about sixty centimeters long with four or six steel bolts at both ends that are used to buckle small holes in the rail.wide, called expansion joints.The small hole that the rails let the bolt through in the fishtail plate is oval so that the rails can have room to expand in hot weather.This is very important for the rails: if there is no room for expansion, the rails need to withstand 16 tonnes of pressure or tension every time the temperature changes by one degree.If there is a difference of 30 degrees between the maximum and minimum temperatures in a place per year, this force can reach 50 tons.As a result, a rail may become skewed, affecting driving safety.Although this can solve the problem of cold shrinkage and heat expansion, the small seams left on the track make the train produce a "click, click" sound when passing by.Unless the rails are very well maintained, such seamed rails are not suitable for high-speed trains; Passengers may also find the ride unstable.Many countries with developed railways still use this type of rail joint on low-speed routes, non-critical routes, or feeder lines.Fishtail plates are also commonly found in routes where there is a lack of modern investment.Most of the routes in the United States fall into this category, and most also use wooden sleeper rails; This is also partly due to the low speed of railroads in the United States and the low price of wood.Another newer method of attaching rails is continuous welding rails, also known as seamless rails or long welded rails.In this method, several kilometers of steel rails are welded into a continuous one.With no joints, the rails are stronger, requiring less maintenance and smoother driving.The cost of welding the rail is more expensive than that of the fishtail plate.However, due to the higher strength, the vehicle can travel at higher speeds on a continuously welded track, and friction is reduced.In order to solve the problem that seamless rails may be distorted during cold shrinkage and heat expansion, the rails need to be tightly locked on the wire, so that their expansion and contraction freedom is restricted.The general practice is to use concrete sleepers, fasten the rails with strong fasteners, and add sufficient ballast underneath.Each time the rails are changed or laid, they are stretched to expand before they are locked onto the sleepers.In this way, even if the temperature rises in the future, the expansion of the rail will be reduced.The temperature at which the rail is locked is also important.Generally, each section of the track will refer to the local maximum and minimum temperatures, and then calculate the appropriate temperature.If the temperature exceeds the initial budget in the future, such as a historic hot summer or cold winter, the seamless track may bend or break.Using a continuously welded track can still use the joint where it is needed.However, most of these joints are not crossed by a 90-degree straight line, but are joined at a very oblique angle.In this way, the vibration and noise of the wheels as they pass through will be greatly reduced, but the rails will still have room to expand.This joint is called an adjustment turnout.Danzhou Station mainly handles part of the passenger and freight transportation tasks in Danzhou urban area and Donggang City under its jurisdiction.At the same time, it is responsible for the important transportation of Danzhou goods exported to North Korea.Danzhou Station has a total construction area of 15,300 square meters and can accommodate more than 2,000 passengers waiting at the same time.The station building is equipped with an entry and exit hall, a domestic waiting hall on the first floor, a domestic waiting hall on the second floor, an international waiting hall on the second floor, a VIP room, a soft seat waiting room and a ticketing hall.Each waiting hall is equipped with a drinking water room and toilet for passengers, which is elegant, simple, comfortable and convenient.Passengers can travel from the spacious waiting hall, through the ticket gates, directly or through the underground tunnel to the platform.Passengers can exit the station directly from the platform or through the underground passage, and go to the departure hall to check their tickets and exit the station.These are all designed by Mrs.
Catherine, the young Mrs.
Catherine in the past year or so, in the case of the original knowledge of architecture, and constantly absorb the experience of builders from all over the world, has become the general person in charge of the construction industry in Danzhou, the national projects are the handiwork of Mrs.
Catherine, and the president of Meng also trusts Mrs.
Catherine."
It seems that no matter what I say, you can understand it, and the drawings drawn are the same as what I said."
President Moe smiled faintly and looked at Mrs.
Catherine, who hadn't spoken to her for a long time.It's mainly because President Meng is busy, and, before the relationship with Princess Katrina Kafu is getting better and better, President Meng is like a suffocated little male dog all day long, thinking about eating women's tofu all day long, thinking about it now, sometimes I feel embarrassed, especially Mrs.
Catherine, he once longed for Mrs.
Catherine, but now that I think about it, it's not immoral, and President Meng blames himself at the same time, and has long dispelled such an idea.Affection, courtesy, this is the traditional morality of the Chinese, President Meng is not bad, stick to it.Mrs.
Catherine smiled indifferently: "Because the president has said it very clearly, otherwise, how can I draw it?"
