Chu Jianghe spoke like this, which immediately attracted the dissatisfaction of many people in the field, and several of them showed a sneer on the corner of their mouths, and looked at Zhao Zongrong, because the test section of the Shentan Railway was proposed by Zhao Zongrong, and Chu Jianghe questioned it so much, which was equivalent to questioning Zhao Zongrong's decision. Pen "Fun" Pavilion www.biquge.info

The corners of Zhang Haipeng's mouth trembled slightly, and he was about to speak, but he felt that what Chu Jianghe said really meant that Zhao Zongrong let everyone guess, and he also put the test section on the Shentan Railway, he definitely wanted to make this test a success.

If this trial operation can't even break the speed of 120km/h, what qualifications can be said to be that the electrification transformation is completed, and the maximum speed will reach 160km/h?

Although Zhang Haipeng is the leader of the chief engineer's office of the Road Bureau, he has a good understanding of some technical problems, in terms of mechanical calculations, compared with Chu Jianghe, the gap is still too big, he only according to his experience, to judge whether this matter can be successful, the scientific basis is insufficient, and he has not experienced anything in design.

In the eyes of everyone, Chu Jianghe's words are more of reasoning and speculation, in fact, what everyone doesn't know is that when Chu Jianghe said this, in his mind, he had already made some calculations, and conservatively estimated that the speed of the train in this trial operation could enter 120km/h, so he would say it so full.

After all, Chu Jianghe knows the line data of the Shentan Railway well, and now Chu Jianghe is worried about the flatness of the two rails, which has a great impact on the speed of the train, once the flatness of the rail is not good, whether the train can enter 120km/h, or a question mark.

"Look at what you said, I'm going to see if the trial operation speed can really reach 120km/h as you said. Zhao Zongrong didn't comment on everyone's words, and said with a smile.

At this time, the train has already exited the remote signal light of Shenzhen Railway Station, and once it has passed the remote signal light of the station, it will enter the section.

"Take the route map of the Shentan Railway, and report the speed of the train every five minutes. Zhao Zongrong said.

The staff put the line map that had been prepared long ago on the table in front of Zhao Zongrong, this line map was drawn with pencil by members of the Chief Engineer's Office of the Road Bureau, but it was large enough to clearly mark the line status of the Shentan Railway on the drawing.

Among them, the length of the interval straight curve, the curve elements, including the radius of the curve, the length of the curve, the curve exceedance, and other data, are clearly marked on the drawing.

At the same time, an employee who was very familiar with the drawings came to the table and explained to Zhao Zongrong: "Zhao Bureau, the remote signal light of the train has just left Shenzhen City, and it is in this position. ”

Looking along the narrator's fingers, Chu Jianghe found that out of the Shenshi Railway Station, there was a curve with a radius of 1200m eight hundred meters ahead.

"What's the speed now?" Zhao Zongrong asked again.

“20km/h。 The person in charge with the speed measuring instrument replied.

Because it has just left the station, the speed of the train is not high.

"Accelerate to 40km/h to curved sections. Zhao Zongrong said.

For this speed through the curve section, it is still relatively conservative, the radius of the curve is 1200m, this curve is relatively slow, and the ultra-high is not large.

After Zhao Zongrong finished speaking, the person in charge of contacting the driver's cab spoke into the walkie-talkie, and in less than five seconds, the train seemed to be suddenly pulled vigorously, and the speed increased slowly.

After a while, a reply came from the intercom, telling everyone that the speed had reached 40km/h and that it was running at this speed.

The distance of 800 meters was quickly reached, Chu Jianghe put a hand on the table, feeling the feeling of the train passing through the curve, it was obvious that at the moment when the train entered the curve, everyone obviously felt that the train was tilting, and moved forward quickly, in general, the train was quite stable, only when it passed through the rail joint, there was a collision sound.

"Passing through the curve, there is a straight segment of 4 kilometers ahead, followed by a right-turn curve with a radius of 1200. As soon as the curve passed, the voice of the report came from the walkie-talkie.

"Continue to accelerate and increase the speed to 60 km/h. Zhao Zongrong said.

For this speed, everyone did not feel how fast, nor did they feel that there would be any danger, because before the Shentan Railway did not change the sleepers, the fastest freight train could reach 60km/h, but it was rarely driven to this speed, and under normal circumstances, the average speed remained 50km/h.

Now this freight train has reduced the freight carriage by half, and on this half of the carriage, the load is less than half of the full load, which greatly reduces the load, and the Dongfeng 4B diesel locomotive is replaced, and the speed is increased to 60km/h, which is very easy.

Because the passenger train is on the Shentan Railway, the fastest even runs to 80km/h.

Everyone sat in the carriage and felt the feeling of increased speed.

"Zhao Bureau, the train runs 60km/h is still very stable. Zhang Haipeng said.

"Yes, apart from the vibrations from the rail joints, the sway of the carriage is not too fast, and the speed can continue to increase. The person in charge of the maintenance section spoke.

"Let's raise the curve in front of you, this section is 38 kilometers, and there is a straight section up to 12 kilometers in front, and then you can continue to increase your speed there. Zhao Zongrong said.

After all, this is a trial operation, and it cannot be said that the speed will run to 120km/h to complete the task, and the key point is to record relevant data for post-study and analysis in the process of speed increase.

Soon, the train drove directly into the curve while running at 60km/h, and this time, everyone clearly felt the sense of shock, and the carriage swayed, giving people a feeling of unsteadyness.

Chu Jianghe still put his hand on the table, feeling the impact of the train, facing the swaying of the carriage, Zhao Zongrong grabbed the table with one hand, looked out the window, and did not speak.

Zhao Zongrong did not say that he slowed down, and no one dared to open his mouth in the carriage, using a speed of 60km/h to pass the curve, although it was not the first time, but most of them were passenger trains, and freight trains had only reached this speed in a straight line.

As the intercom heard that it had passed the curve and entered the straight section again, many people in the carriage breathed a sigh of relief.

"When the train passes through the curve, the speed is still not stable enough. The person in charge of the depot spoke.

"Yes, the shock is quite severe, it seems that the train passes the curve at a speed of 60km/h, and it is still necessary to slow down appropriately!" Zhang Haipeng frowned.

"I don't think so, the carriage shook just now, which is obviously the reason for the line. At this time, the person in charge of the public works section spoke.

After the person in charge of the public works section finished speaking, many people looked at each other, and Chu Jianghe also looked at each other, in fact, the other party's thoughts were similar to what Chu Jianghe thought.

Through Chu Jianghe's feelings and observations, when the carriage passed through the curve, in addition to swaying from side to side, there was also a sense of jolting, which was quite powerful, but everyone was attracted by the swaying of the carriage, so they ignored this problem.

"Chief Li, tell me what you think. Zhao Zongrong said to Li Duan of the Public Works Section.

"Zhao Ju, I have been working on the line for more than ten years, once the carriage swaying, in my opinion, the biggest reason is that there is a problem with the gauge of the two rails, otherwise, even if it passes through the curve, there is rarely a swaying phenomenon. Li Duan said.

In railway construction, construction experience is indeed very important, the old lineman, can look at the passing train, or lie on the rail, to determine where there is a problem with the rail, whether it is the gauge or elevation, or the two rail triangular pits.

"I agree with Li Duanchang's words, and you feel it, when passing through the curve, the carriage not only swayed, but also bumped, although I don't understand the railway things, but I often drive, when the car sways up and down, usually because the road is uneven, or it is bumpy and bumpy. As soon as Li Duan Chang finished speaking, Chu Jianghe also spoke.

In order to cover up his understanding of railway operation, Chu Jianghe thought about it, and finally could only compare it with a car, but in fact, the truth is the same.

Chu Jianghe's sudden remarks surprised everyone, but listening to Chu Jianghe's words, he did feel some truth, and this metaphor was quite appropriate.

"Bumps up and down, young man, do you feel this?" Zhang Haipeng couldn't help but speak, because he only felt the carriage swaying, but he never felt the bumps up and down.

"Mr. Zhang, Jiang He is right, when the train passed the curve just now, there was indeed a bump up and down, which I can affirm, and it is relatively strong, but it is slightly weaker than the carriage swing, maybe you haven't noticed. In the face of Zhang Haipeng's questioning, Li Duanchang actually stood up and agreed with Chu Jianghe's words, the two seemed to sing and harmonize, and they cooperated very well.

"Yes, when you go through the curve, there is a sense of bumpiness. Just when Zhang Haipeng was about to speak again, Zhao Zongrong said his feelings at this time.

Zhao Zongrong opened his mouth, Zhang Haipeng was speechless, as the deputy director of the Shenzhen Branch, he would definitely not say nonsense, since Zhao Zongrong said so, there must be such a situation.

"It seems like there's another curve ahead, so let's all experience it together. Chu Jianghe glanced at the drawings and found that after the curve just now, he entered a straight line of 400 meters, and then there was a curve with a radius of 800m.

Compared with the curve radius with a radius of 1200m, the greater the speed, the greater the risk, and the smaller the curve radius, the more it can reflect the problems existing in the train.

"Yes, everyone has a good feeling this time, and it's not too late to express your opinions later. Seeing that Zhang Haipeng's face was not very good-looking, Zhao Zongrong spoke.

Soon, the train drove into the curved section ahead at a constant speed of 60km/h, and Chu Jianghe put two silver coins of two cents on the table!

This time, from the moment the train entered the curve, the carriage began to sway, and the length of the swing was stronger than that of the previous curve.

As for the silver coin that Chu Jianghe put on the table, the moment the train entered the curve, it shook rapidly, jumping up and down!
