C145 Breaking Through the Technological Barrier and Opening It up

Everyone's eyes are on the board, and the board respectfully bows to Chang Hong.

Chang Hong raised his hand, gesturing for Director He to stand up. Director He smiled with narrowed eyes, took the chair that Secretary Chen had brought over, and sat on one side of Chang Hong.

"Little He, you came just in time. Come, come, tell everyone about the matter of the talent deployment of the Beijing Broad Creed railway. " Chang Hong gave the right to give a speech to Director He.

Director He respectfully nodded. "Alright, before I give my speech, please move to the meeting room. "

Everyone looked at each other and followed Director He towards the conference room.

Zhang Hong approached Zhao Cheng, "Bureau Chief He was called over by you?"

"I didn't receive any notice. . . Isn't it the Division Chief?" Zhao Cheng had a puzzled expression.

Zhang Hong and Zhao Cheng looked at each other for a few seconds before looking at Zhang Yu. Zhang Yu quickly waved his hand, "I also don't know why Chief He came. "

"Could it be Teacher Chang?" Zhang Hong seemed to understand something, "After returning from Beijing, Teacher Chang chatted with Chief He for a long time. "

"Maybe it is some kind of work arrangement?" Zhao Cheng was puzzled, "It can't be the Beijing Broad Creed railway, right?"

"It's possible. " Zhang Hong blinked his eyes and suddenly had a flash of inspiration, "I remember now, some parts of the Guangjing railway are similar to the landforms in Western Europe and Central Asia. It's said that before the 2012 operation, we need to gather some information and prepare for the railway brand to go overseas. This might be the case. "

Zhang Hong's words also made Zhao Cheng react. "That's right, I also agree with Teacher Qiao. Could it be that we will start to finalize the name list today?"

"It is very likely. " Zhang Hong said affirmatively.

"Looks like Da Su is going on a business trip. " Zhao Cheng sighed and called out to Su Jianguo, "Da Su. . . "

"Teacher. " Su Jianguo walked in front of Zhao Cheng and said respectfully.

"Have you heard of the recent news regarding the shield construction machine and the excavation of the tunnel?" Zhao Cheng asked.

"Teacher, I don't know" Su Jianguo was doubtful. "Could it be. . . "

"Jianjun. . . " Zhang Hong also shouts and Jianjun Chen walks in front of Zhang Hong.

"Jianjun army, have you heard of the railway bridge that reduces the area it covers?" Zhang Hong asked.

"I've heard of it, Zhang Ke" Cheng Jianjun was puzzled, could it be that today we are going to bring up this matter?

"Why do I feel like today's matter has something to do with these two technologies?" Zhao Cheng said.

"No matter if it's true or not, we'll know once we go in" Zhang Yu smiled and dispelled their doubts. He followed Chief He and the group to the meeting room.

This was a large meeting room of Shanghai's railway department. There was a projection in the meeting room. On it was the Wuguang railway, also known as the Jingguang railway.

"Everyone, it's an honor to be able to invite all of you here. Today, I will show you the demonstration of the construction of the Jingguang railway. According to the higher-ups, we will be operating a high-speed train with a speed of 350km / h during the 2011 test. " Chief He pointed at the CCMAU railway on the big screen and said.

"As the CCMAU high-speed railway Zheng Wu Duan crossed the King-Hong Kong and Macau highway and the Shanghai Hanrong high-speed passenger channel, the security of the construction is more difficult, so the next problems we will encounter are: the Mulan Tunnel and the Yellow Dragon Temple Tunnel with severe water crashes. " Commissioner He switched to the PowerPoint and continued.

At this moment, Director He was like a celebrity standing in the middle of the stage. "The construction process involves the basics of the road, bridgehead, tunnel, ballast rail lines, precise measurements, quadruple power integration, station construction, customer service information, and so on. Due to the professionalism of these professions, The process is complicated, the process and the transition between the professions are frequent and complicated. The conversion between the underline and orbital projects, the conversion between the front and rear projects, the conversion between the main and auxiliary projects all require professionals, so we have decided to transfer young professionals in various fields such as earth and wood engineering, electrical engineering, and air dynamics. . . We will go to the construction site to personally participate in the construction. "

Commissioner He turned around and looked at everyone present. "According to the plan, we have decided to learn from the experimental section of the ballast track and the experience of the construction of the Great Yaoshan Tunnel. Perfect connection with the road and other means of transportation to achieve a change of 'zero distance'. A large number of "bridge to replace the road" designs were implemented. Pushing the bridge's tunneling path to 81% was beneficial in ensuring the quality and operation safety of the circuits. A large amount of land resources will be saved. "

As soon as Chief He finished speaking, dozens of young designers and engineers came in one after another.

Su Jianguo and the Jianjun Corps looked at each other. It seemed like they were going to arrange for the designers and engineers to go to Beijing to build the railway.

"Next, I will talk about the technical requirements and personnel transfer. " Chief He and the others nodded. First, we'll head to the Dayao Mountain Tunnel Engineering Training Base. According to the implementation plan, we need to do drainage and archive work in the early stages of the tunnel excavation. Therefore, we need to ask Su Jianguo and the Chengjian Army to lead the team to participate in the training of loading machines and standard drilling machines, and to complete the further studies of internal combustion, hydraulic pressure, and electrical energy. Your task is to master the training of non-electric Mini Mini Minute Bomb, the training of the flamethrower support, the training of waterproof board construction, the training of pumping concrete, and write a report. Let the experience pass down. "

Chief He's words made Jianjun Cheng and Su Jianguo stand up and say as if they were accepting a mission, "Yes, Chief He. "

[Please refer to the construction of the Great Yaoshan Tunnel that I have experienced. ]

"You must remember the beginning of the Great Yaoshan Tunnel's fully automated construction. It is also the beginning of the domestic fully automated construction of the tunnel! The Great Yaoshan Tunnel was a construction in 1988! Today, in 2008, the Mulan Tunnel and the Yellow Dragon Temple Tunnel will be connected. This battle will only be a success, no failure!" Commissioner He said with a solemn expression.

"Commissioner He, we will definitely not fail our orders!" Su Jianguo said.

"Bureau Chief He, we will definitely succeed!" Chengjian Jun said.

"Very good, next. I'll arrange for the learning work of large machines. Receiving the notification from our brothers, this time we will have the drilling holes of the Atlas four-armed vehicle, the anchor of the Atlas two-armed drug truck, the Swede Type-jet Trio, the Consolidated Jet Machine Gunner, the Domestic PH30 Jet Spray Machine, the Volvo Loader, the large Italian self-unloading truck unloading and unloading, and so on. I request. . . Zeng Yi, Wang Cheng, Liao Qing, and Zhang Qi to master the manual maintenance and operation of these machines! " Commissioner He looked at the engineers, It was as if he was entrusting a heavy responsibility to them.

"Yes, Bureau Chief"

Chief He clasped his hands and looked at the geological designers. "Comrades, our railway department has done an outstanding job of connecting the complex terrain to the tunnels.

1983, 8th to Dec. , five consecutive months, two two-line tunnels, a hundred meters deep;

In November 1983, we created a two-line tunnel with a monthly hole of 152. The national record of 04M, Iron Path Department sent a congratulatory message;

In September 1984, the Double Line Crescent Tunnel was set at the exit of the Great Yaoshan Tunnel. The latest domestic record of 68M;

In 1984, there was an average of 150m of the Double Line Crescent Tunnel. Nineteen meters, followed by the main task of the ninth fault.

On May 6th, 1987, in the 1994 + 747 branch, they connected the Great Yaoshan Tunnel with their brothers, and the Deputy Prime Minister of the State Department, Wanli, attended the ceremony.

On July 30, 1988, the Great Yaoshan Tunnel was completed.

On August 4th, 1988, the Great Yaoshan Tunnel was paved on both tracks.

The first train successfully passed through the Dayao Mountain Tunnel on 26th, Nov, 1988, signifying the completion of the Dayao Mountain Tunnel.

The Great Yaoshan Tunnel received the National Science and Technology Promotion Special Award, followed by Heng Guang and received the National Quality Silver Award. "

Chief He looked at everyone with a smile on his face," The Great Yaoshan Tunnel's success has been ten years. I don't believe that ten years later today, our technology will regress! So. . . "

Chief He pointed at the Huanglong Temple Tunnel on the PowerPoint and slowly said, "Huanglong Temple Tunnel. Located in Xinyang City in Henan Province and Da Wu County in Hubei Province, the plan is 8725 meters long. It is the longest tunnel along the Shiwu Road. If it is built, However, there were five major cracks in the main area of the tunnel of Huang Long Temple. The cracks were the structure of the debris, without any adhesion. The water conductivity and the richness of the water are better. The maximum water surge is 187m3 / D. "

Due to the need for professional technology, part of the railway technology and engineering terms are written in the whole text.

Chief He looked at every expert present. "Since the tunnel is made of solid granite through the rock stratum, Digging is extremely difficult, and Wuguang Customer Ltd has listed it as a throat project to the north. Currently, the construction of the Huanglong Temple tunnel is still in the siege phase. I hope that you experts can also head to the construction site of the Huanglong Temple tunnel. Give them some technical support and know. "

Chang Hong sized up the tunnel and said slowly, "I think I've analyzed the geology of this area. Old Qiao, do you think it's possible to build a horizontal tunnel and two slanted wells in order to expand the workspace and relieve the ventilation pressure in the tunnel?"

"It's possible. By increasing the eye of the cannon and strictly controlling the depth and sequence of each explosion, it can increase the light explosive effect and increase the efficiency of digging. " Qiao Heng said from his own expert point of view, and his assistant handed Qiao Heng a document. Qiao Heng handed the document to Chang Hong, "I went to inspect it a few years ago, and felt that it was quite good. "

"But how can it be carried out safely?" Chang Hong began to reflect.

"Isn't Old Wang an expert in this aspect?" Qiao Heng chuckled and looked at Wang Xiao, "Old Wang, what's your opinion?"

"According to the requirements of specialized construction team, systematic equipment configuration, standardization of construction processes, and on-site management standards, the construction team follows the principles of" minimum workplace, maximum workload, best equipment configuration, and the most optimized work efficiency. It can effectively increase the progress of the excavation of the tunnel and ensure the completion of each node. " Wang Yixiao quickly drew on the paper. "When I return, I'll make a trip to Yellow Dragon Temple to take a good look. Then, I'll give you a specific standardized operation plan. "

"How long?" Qiao Heng asked.

"Half a month. " Wang Yixiao had given him a deadline.

"Alright. " Chang Hong nodded.

"But. . . This place seems to be using the CRTS Model II ballast track. " Qiao Heng reminded.

"This. . . Qiao Heng, you are an old expert in this area. Do you think it is possible to build mountainous areas?" Chang Hong became curious.

"The northern section of the Shiwu high-speed rail is located in the Great Bianshan area, if it's completed. . . That would be the first time in the world that a CRTS 2 model ballast track has been built in the mountains. Such a proud project. . . Can you say no? Even if you can't, you have to! I, this old man, like to challenge high difficulty. Didn't you say that I would only start work on the New Year's Day of 2009? Don't worry, I still have half a year to conquer it. I already have the preliminary experimental data. I should be able to use it. " Qiao Heng smiled and narrowed his eyes.

"Emotional, you even prepared something?" Chang Hong burst into laughter.

"Why else would it be Old Qiao's head?" Wang Yi laughed.

Chief He smiled as he looked at the three old experts, whose average age was seventy years old. It was China's good fortune that China's railway had such old experts who were wholeheartedly devoted to their country.
