Deng Chuan: Looking at the square in the square inch, watching thousands of miles of scenery

China Youth Net, Xi'an, August 10th (Reporter Zhang Yayun) For an hour, an adult can only go to a five -kilometer journey, while taking the high -speed rail, he can pass 350 kilometers and watch the mountains and rivers.

In the fifth year of the 21st century, my country's high -speed railway began to be built and gradually became an important part of the development of the national economy. This year, the 18 -year -old Deng Chuan was still a freshman who had just entered the university. Seeing the vigorous development of the national high -speed rail, he had a desire to devote himself to the construction of high -speed rail.

In order to ensure the safety and comfort of the train operation under high -speed driving conditions, the track of the high -speed railway must maintain a long and stable high -smooth state, and the rail measurement is a key process. This also makes the "method and efficiency of rail measurement" a A difficult point in the large -scale construction and operation of high -speed rail. "Our team focuses on the" key technologies and equipment "of the" high -speed railway rail rails smooth measurement "is to solve this problem." Many years later, Deng Chuan represented his own unit -China Railway First Survey and Design Institute Group Co., Ltd. The Bank Cup "Shaanxi Province's second state -owned enterprise youth innovation and creation competition road show shows the results of their team's research.

Control the parameter accuracy to "sub -millimeter level"

The higher the accuracy of the smooth measurement of high -speed rail rails, the more you can detect whether the derailed status is straightforward and unable to smooth, whether it meets the design requirements. If the measuring error is large, if the error exceeds 1 mm, the train will feel like a car and vibration during the train driving. It is a long process to control the precision of the orbit geometry to the "sub -millimeter level". Before the time was pushed back to the 1990s, the measurement of the rail geometric parameters was mainly artificial methods. Later, in order to meet the initial construction needs of the high -speed rail, my country has introduced a large number of foreign related technologies. The higher the speed, the measurement accuracy is increased by one millimeter.

The high -speed rail crosses things, runs through the north and south, the extremely cold weather in the north, and the humid environment in the south will affect the rail measurement. Deng Chuanhe team is doing it to continuously use innovative technology to solve difficulties and ensure the normal operation of the high -speed rail. After step -by -step efforts and experiments, the rapid measurement system they developed to achieve the precision measurement of the rail geometric parameters of the rail geometric parameter, and controlled the error below 0.3 mm.

"Rigidity is an essential quality. In work, you must have enough carefulness and patience." For young people who want to enter this industry, Deng Chuan wants to tell them the most.

He walks in mountains, lakes, and nights during the night

Rail measurement is generally arranged at night, because the construction of construction or large -scale machinery and equipment during the day will occupy the rails, which will affect the measurement accuracy.

"It's another sleepless night." Watching the pointer of the watch shifted from midnight to dawn is the normal work of Deng Chuanhe team. "We often tease our work is five plus two, white plus black, but if you are not in the first line, you will not go deep into the line, but if you don’t go deep into the first line, you will not go deep into the front line. Can't master the demand on the spot well. Only by really doing this job can you know how much the high -speed rail smooth measurement efficiency is restricted to the operation of high -speed rail operations. "Deng Chuan is more concerned about the progress of the project research and development than the hard work of the work.

As a pioneer of survey, in the past ten years, Deng Chuan has crossed the inaccessible desert, plateau, forests, and snowfields, but when he is sitting on the gallium high -speed rail, thinking of the technology he developed is serving the operation of the high -speed rail, all the hardships are all hardships all hardships. Pointed out the window.

“和同事一起坐高铁时，我们会准确的报出下一个隧道的名字，途经的车站，旁边有哪些控制点，当时是谁去的这个地方、待了多久……”每每回忆起来，总是The sense of accomplishment is full of these little joy, filling the daily surveying and mapping work of Deng Chuan.

It's a stadium and a classroom

Participating in this competition is a new challenge for Deng Chuan. Most of the projects that are shortlisted for the finals of the Second State -owned Enterprise Youth Innovation and Effect Contest in Shaanxi Province, most of them come from high -precision projects from aerospace, military and research institutes. Completed the "defense+roadshow" session.

"I also listened to the reports of others seriously during the competition. From their roadshow methods, explanation manuscripts, stage display, audience interaction, questions and answers, etc., the creativity showed me a comprehensive learning opportunity." Compared to compared to compared to In the field, Deng Chuan felt that it was more like a classroom.

Looking back at the course of the 4 months of the competition, Deng Chuan felt that he had encountered a brand new self. "I have come into contact with new things in many other fields, which will also inspire me to continue to struggle and make greater progress." Deng Deng. "Deng Deng. Sichuan said.
