Qidong Creates "Micro Innovation" Technology to Solve Highway Maintenance Problems

“Shovel and brush”Gizmo，Shorten the construction period by at least 10 days；Small improvement of test detection，Save about 72 labors……One day，The reporter learned from Qidong Highway Department.，Since this year，At“East Xinjiang Heart Road”Under the guidance of Party building brand，Exploration and Application of Qidong Highway Sub-center“Four new technologies”，Actively promote the process of scientific conservation，AtS356 During the construction of major and medium maintenance works，Use it well“Micro-modification of equipment、Process micro-innovation”Two keys，Build“Micro-innovation”Craft，Promote high-quality construction of projects。

“‘Shovel and brush’Seemingly insignificant，But the construction period has been shortened by at least 10 days.。”Relevant person in charge of Qidong Highway Center.，SThe asphalt milling material at the longitudinal joints on both sides of the upper layer of Qidong Section of 356 Medium and Large Repair Project is not easy to clean and has a certain bonding force.，Especially, it is easy to harden after being exposed to the sun or rolled by Vehicles.，It is difficult for the road surface dry cleaning Vehicle or hair Dryer to completely remove the waste.。For this situation，The Party Group of Qidong Bid Section has thought and invented“Shovel and brush”Two utilities，During construction, press“Shovel, brush and blow clean”Thoroughly clean the longitudinal joints in the order of。“Shovel and brush”The application saves about 100 people.，Shorten the construction period by at least 10 days，The asphalt milling materials at the corners are thoroughly cleaned.，The hidden danger of pavement construction quality is eliminated.。

Small improvement of test detection，Save about 72 labors。Core sampling is an important method for quality inspection of asphalt pavement，The hole repair level of core sample directly affects the appearance and quality of asphalt pavement.。The Party Group of Qidong Bid Section considers and improves the shortcomings of the traditional core-drilling repair method.，Formed a relatively perfect“Core drilling, sampling and testing—Core sample hole repair”Innovative operational processes。For example，On the transportation mode of core drilling machine，The Party group installed a small motor on the tool car transporting the core drilling machine.，Change the traditional manual handling into mechanized lifting，Realize single-person operation，Save about 72 labors，And that potential safety hazard in the manual carry process is greatly reduce.。

Qidong Highway Department will continue to study，Through minor reforms、The way of excellence，Solving the Pain Points in Highway Maintenance and Repair、Difficult problems，Improve maintenance management effectiveness and maintenance quality。
