Addition of wave-shaped anti-collision guardrail“Column driving”The machinery roared、Pothole filling site“Dig and mend”The dust is flying、Tacit Cooperation of Bridge Disease Detection and Evaluation Players“Test record”…… 10-12 November，The 13th National Transportation Industry Highway Maintenance Professional Skills Competition was held in the National Final.,Real“Restore”The daily work scene of the maintenance workers is in full swing.。

From more than 20 provinces across the country（City、District）102 contestants competed on the same stage.、Live contest，Flashing out one after another“Unique skill”，Brought a road maintenance skills.“A visual feast”。

Pothole filling of staff group

Measure the distance with both feet，Build a smooth road with ingenuity。Highway maintenance workers are the key to ensure traffic safety and smoothness in the field of highway construction.、Maintain complete highway facilities、A very important profession that creates social and economic benefits.。There are more than 800,000 highway maintenance workers in China.，They charged ahead in the emergency.，Continuous reform and innovation in maintenance technology，Provide more security for the people、Clear、Comfortable travel environment。

“In view of the importance of the profession of highway maintenance workers and the large number of practitioners,，It is of great significance to list it as one of the events in this competition.，It is a great affirmation and incentive for maintenance workers.。”Ouyang Wei, Head Referee of highway maintenance, told reporters.。

Theoretical knowledge contest,The contestants take a closed-book test.，The question bank mainly covers highway maintenance.、Maintenance of Highway Asphalt Pavement、Highway Bridge Conservation、Maintenance of highway tunnel、Highway maintenance safety operation、Technical condition of the highway、Technical condition evaluation of highway bridge、Quality inspection of highway maintenance engineering、Current norms and standards for the occupation of highway maintenance engineering technicians、Basic knowledge and common sense。

 

Addition of wave-shaped anti-collision guardrail for staff group 

In the skill operation competition，All the differences in the focus of the competition between the staff group and the student group。”Ruan Zhigang, Director of Road and Bridge Department of Sichuan Vocational and Technical College of Communications, introduced.。

“The three projects of the staff group are closely related to the reality of highway maintenance.，In particular to the addition of a waveform guardrail.、Pothole repair project，Completely added with reference to the actual operation of highway maintenance，It not only tests the players' practical skills on the spot.，At the same time, it also tests how the players use information-based technology and equipment to carry out maintenance work.，This is one of the highlights of the game.。”Ruan Zhigang explained。

“Student group events tend to be considered from the perspective of theoretical study and future development of highway maintenance.，Test player for modern‘Non-destructive testing’Grasp the development direction of maintenance technology in the future based on the operation ability of instruments and equipment and related technical evaluation.。”

 

Bridge Disease Detection and Evaluation of Staff Group 

On the field of skill operation，Two contestants from the staff group of highway maintenance workers cooperated.，Operate skillfully against the clock，One process after another is accurate and coherent，Everywhere the details are smooth and standard.，Each movement is focused and steady.，The players all put their special skills into the intense skill competition.。

Bridge Disease Detection and Evaluation of Staff Group、Wave-shaped guardrail is added、Pothole repair 3 events，It mainly examines the damage of a beam of a bridge provided by the contestants within the specified time.（Simulate the disease）Investigate and record data；Complete the pothole repair at the designated location in a standardized and civilized manner；2 columns shall be driven and 2 steel guardrails shall be installed at the designated position。

 

Inspection of wave-shaped beam anti-collision guardrail for student group 

The test items of the wave-shaped beam anti-collision guardrail of the student group、Bridge Disease Detection and Evaluation Project、Crack width development monitoring project，It is mainly to examine the damage of one beam of the bridge within the specified time.（Simulate the disease）Investigate and record data；Inspect the metal wall thickness of the column base of the installed guardrail、Plating（Tu）Layer thickness；The development of the simulated crack width of the structure and the slope is monitored by the Internet of Things technology.。

 

Monitoring the development of crack width in student group 

Install the crack meter、Build a monitoring system、Complete system construction and debugging……Reporters in the student group crack width development monitoring project site to see，Two student players in light blue uniforms，Directly opposite a fracture width variation simulation model，Coordinate operation in an orderly manner，Jointly complete the monitoring、Record、Transmission, analysis and filling of crack width development monitoring record form。

The game is in full swing，The players are methodical。Pecially in the stage of automatic data acquisition.，Players are required to accurately grasp the collection time.。The acquisition interval shall not exceed 3 seconds.，And upload the monitoring data to the competition data platform in real time.，The duration of data acquisition shall not be less than 300 seconds.。After the data collection is completed，Players should make an accurate judgment on the change trend of crack width according to the recorded data.。If the result is not submitted within 30 minutes of the time limit, the event will be 0 points.。

 

Detection and Evaluation of Bridge Defects in Student Group 

“As a student, I was excited and nervous to participate in this national first-class competition for the first time.，No matter which event it is, it is a big test of our skills.，I also learned a lot through this competition.，For me who is about to graduate.，I am honored to be able to participate in this competition.。”Song Xipeng, a student player of the Sichuan team, said.。

Zhou Yujing, a staff member of the Sichuan team who has been working for more than ten years, said.：“Today's highway maintenance operations are practical and technical.，Only by constantly studying can we make progress.。Like in pothole repair.，Seemingly simple，Not only to be skilled in the use of new technology and equipment，Have to patch up the pothole perfectly.。I am very happy to be able to participate in this competition.，It gives us the opportunity to demonstrate the professional skills of highway maintenance in the national competition.。”

After the fierce competition between the teams and the participants.、The referee judges、Comprehensive evaluation，Peng Zihao, Representative Team of Zhejiang Provincial Communications Department, Staff Group、Jin Junlian won the first place.、Zhou Yujing, representative team of Sichuan Provincial Department of Transportation、Pei Hongbo won the second place.、Wu Yue, Representative Team of Jiangsu Provincial Department of Transportation、Ding Yu won the third place.；Student Group: Sun Hang, Nanjing Vocational and Technical College of Communications、Zhu Kun's team、Xu Zhilin, Jiangsu Traffic Technician College、The Mongolian gazelle becomes a team、Sichuan Vocational and Technical College of Communications Zhu Jinteng、Song Xipeng's team won the first prize。
