In highway maintenance work，Technological transformation is to achieve technological progress.、An important way to improve the quality and efficiency of work。In recent years，Guixi Highway Development Center Actively Adapts to the Specialization of Highway Maintenance Management in the New Era、Higher requirements for mechanization，Take fine maintenance as the starting point，Vigorously promote the technical transformation of maintenance machinery and equipment，Development and modification of outlet ditch cleaning device、Road surface and shoulder cleaning equipment、Guardrail cleaning equipment and other 18 mechanical equipment，It has played an important role in highway maintenance operations.，Effectively promote highway maintenance to reduce costs and increase efficiency。

Brainstorm，Set off an upsurge of technological transformation

Highway departments in western Guangxi give full play to“Engineer”Action，Around“Innovation enables to improve quality and efficiency”Request，Mechanical efficiency will be improved、Reducing labor intensity as the goal of technological innovation，Elaborately developed and highly practical、And that use efficiency is high、Low cost maintenance machinery。Each highway maintenance center exerts its subjective initiative，By maintenance technician、First-line maintenance workers、Mechanical operators and others form a technical innovation team.，Carry out scientific research and tackle key problems，Learn through observation、Concentrate on the discussion、Research and experiment，Autonomous coverage of shoulder maintenance、Facility cleaning、Ditch cleaning、Road cleaning and other aspects of the mechanical technical transformation.，The results of technical transformation will be extended to other highway maintenance centers.。

January 2021，In order to solve the problem of road cleaning, Ningming Highway Maintenance Center，It took three months to organize technicians and front-line maintenance workers.，Invest less than 2000 yuan，The maintenance vehicle is transformed into a road sweeping device.，This problem has been solved well.。And then，Yongning、Ning Ming、Longzhou、Jiangzhou、Shanglin Highway Maintenance Center has successively drawn lessons from the application of this technology to achieve similar mechanical transformation.。

2022，Binyang Highway Maintenance Center has a large number of highway protective fences in its jurisdiction.、The fact that manual cleaning is time and money consuming，Organize personnel to carry out technical transformation of maintenance machinery，It took one month.，Transform the maintenance vehicle into an intelligent guardrail cleaning machine。At present，Nanning Jiangnan、 Hengxian 、Jiangzhou、Longan Highway Maintenance Center also uses maintenance vehicles to transform into cleaning equipment and put it into use.。

“It took only 2 days from the start of technical transformation to the successful development.，It costs 200 yuan to transform the ditch cleaning device.，It not only improves the utilization rate of machinery and working efficiency, but also improves the working efficiency.，It also solves the problem of shoulder maintenance.。”The technical renovation team of Mashan Highway Maintenance Center introduced.。At present，Fu Sui、Ping Xiang、Ning Ming、Shanglin Center is learning from it.、On the basis of the application of this technology，It has been upgraded and put into use according to the actual needs.。

Each shows his own magic，The technological transformation has achieved fruitful results

Highway maintenance involves a wide range of work.，The overall workload is large.，The purpose of technical transformation is to improve the performance of mechanical equipment.，And that labor intensity of worker is reduced，O as to achieve the purpose of improving the maintenance efficiency.。Technical innovation personnel of highway maintenance centers give full play to their collective wisdom，Carefully modify the maintenance machinery，Stimulate the new kinetic energy of maintenance equipment，Opening up a new path to reduce costs and increase efficiency。

Jiangzhou Highway Maintenance Center according to the needs of highway pavement cleaning，A high-power blower and a ground shovel plate are additionally arranged at the tail of the right side of the maintenance vehicle.，Transform to be stable and practical、Convenient and flexible road scraping and blowing machine，Crushed stone on the road surface can be removed during operation、The accumulated mud is scraped loose，The garbage on the road surface is removed by a blower.、Gravel、Clean up the accumulated mud，Achieve the purpose of road cleaning。

Nanning Jiangbei Highway Maintenance Center relies on the original forklift to develop a ditch cleaning device，Add a bucket that can be resized to the actual width of the ditch，To accommodate gutter cleaning，Lower the bucket along the edge of the gutter to the bottom during up，The forklift moves forward to push the small bucket to easily shovel the silt out of the drainage ditch.。

Binyang Highway Maintenance Center adds generators to maintenance vehicles、Pump、High pressure water pump、High pressure sprinkler、Roller brush and other components，An intelligent guardrail cleaning machine is developed.。When cleaning the guardrail，Spray the guardrail wet by the sprinkler first.，The two rolling brushes cooperate with each other to brush dirt.，Finally, the high-pressure nozzle is used for strong cleaning.。

Technological transformation and empowerment，Maintenance efficiency to a higher level

Ditch cleaning device、Road surface and shoulder cleaning equipment、Guardrail cleaning equipment and other seemingly ordinary small technological innovations.，However, it has played a great role in highway maintenance.，Effectively solve the difficulties in daily maintenance、Pain points and blockages，Effectively improve the fine level of highway maintenance。

On National Highway 359，Maintenance workers of Jiangzhou Highway Maintenance Center are using road scraping and blowing machines to clean the shoulders.。“Since the use of this machine.，A person driving a car can sweep the shoulder clean.，It provides a working artifact for our front-line maintenance workers。”Watch the road scraping machine work and leave a clean shoulder.，Huang, the stationmaster of the maintenance station of the center, could not help praising.。

Binyang Section of National Highway 322，A guardrail cleaning truck flashes yellow warning lights.，Stretch out the mechanical arm tightly.“Hug”Hold the guardrail，By spraying water、Roller Brush、Washing and other processes will clean the guardrail in all directions.，Achieve cleanliness、Decontamination、 Protect 、Efficiency“Four in one”The effect of。It took one month for Binyang Highway Maintenance Center to maintain and clean the protective fence of the whole line.，After cleaning the implement with guard rail，Only 7 man-days。

Other technological transformation achievements have also achieved remarkable results.。The drainage ditch cleaning device developed by Nanning Jiangbei Highway Maintenance Center can clean up 3% of the drainage ditch sediment per hour-5 cubic meters，One machine can replace the work of about 13 people a day.。Longan Highway Maintenance Center has carried out technical transformation of tipper loaders.，It can renovate about 2 kilometers of high shoulders every day.，Work equivalent to 15 persons per day，Comprehensive cleaning of high shoulders at one time，And doe not damage that shoulder wall of the highway.。

At present，The technical transformation of maintenance machinery in highway departments in western Guangxi is still in progress.，Each subordinate highway maintenance center combines the actual needs of highway maintenance.，Research and use of existing machinery for upgrading，Through mechanical transformation“New engine”，Continuously strengthen the application of mechanical equipment in maintenance management，Stimulate highway maintenance“New vitality”，Burst out new kinetic energy for high-quality development of highway work。
