Vigorously Promote the Application of "Four New" Technologies to Help Intelligent Maintenance of Expressway

Driving inG72 Hengzao Section of Quannan Expressway，The navigation suddenly sent a prompt.：GThere is road-occupying construction on the left side of 500 meters in front of Hengzao section of Quannan Expressway，Construction length: 520m，Please drive carefully。

Small in size“Early warning wizard”Arranged on the safety cone barrel，Automatic implementation and AmapAPPSeamless docking of data platform

This is from Amap.APPTips in the book，From Hunan High Speed Construction Engineering Co., Ltd.（Hereinafter referred to as“Engineering Company”）Highway maintenance applied by Yongzhou Maintenance Project Department“New technology”---One cone barrel located in front of the work area“Early warning wizard”。

The appearance of this small cone is no different from that of an ordinary cone.，However, its ceiling lamp concentrates on high-precision positioning.、IntelliSense、Information collection and release、Automation management and other service functions in one.，By using AmapAppSeamless real-time docking of data platform，Achieve daily maintenance、Emergency rescue、Real-time and accurate collection and release of information such as road-occupying construction，Drivers and passengers can navigate throughAPPVoice prompt for，Remote prediction of road construction ahead、Occupy the road、Closed、Control and other information，Effectively improve the safety factor of highway maintenance operations，For the smooth operation of highway maintenance、Provide strong guarantee for safe development。

In recent years，In order to promote the scientific maintenance process of expressway，Engineering companies actively promote new technologies for high-speed maintenance and construction、New Technology、New materials、Application of new equipment，Strive to Promote the Sustainable Development of Expressway Maintenance，Guarantee the safety of people's lives and property，Start a New Journey of Intelligent Maintenance of Expressway。

Thermal regeneration equipment，Adopt new technology of thermal regeneration，In-situ pavement rehabilitation through recycling of existing materials，Complete regeneration overlay at one time，Achieve efficient maintenance and construction、Environmental protection、Energy saving and cost reduction，Practice the concept of green maintenance and development。

Repair of pavement potholes with hot recycling curing equipment

Anti-collision buff Vehicles，It will greatly eliminate the potential safety hazards of maintenance operation in high-speed daily maintenance construction.，Guarantee the maintenance operation、Safety of drivers, passengers and equipment，At the same time, the traffic can not be interrupted.，Improve the efficiency of maintenance construction。

The anti-collision buffer Vehicle is used in daily maintenance and construction operations.

Multifunctional sweeper，Set automatic cleaning、Vacuum and spray、Garbage recycling as a whole，Effective operation speed up to 60km/h，Greatly reduce the time of maintenance and cleaning operation，It greatly improves the efficiency and safety of maintenance and cleaning operations.，It effectively solves the difficulty of highway cleaning and maintenance.。

Multifunctional Sweeper Carries out Maintenance Operation on Expressway

Multifunctional hedgerow trimmer，It is suitable for pruning the green belt in high-speed maintenance.、Slope weeding and pruning、High branch pruning，Trimming speed is 10% of traditional manual trimming-20 times，Fficiently solve that problems of maintenance operation, green and pruning，And that occupy time of the high-speed maintenance road is reduced.。

Multifunctional hedgerow pruning machine instead of manual work for high branch pruning

Curing“Cloud monitoring”，Let the maintenance Vehicles be equipped with high-tech“Clairvoyance，Downwind ear”。Timely understanding of road condition information through real-time monitoring、Live information on maintenance operations，It greatly improves the efficiency and accuracy of maintenance patrol data acquisition.，It can greatly improve the safety guarantee coefficient of maintenance inspectors in disease-prone areas.。Achieve the maintenance operation environment“Full coverage、Available full time、The whole process is controllable”。

“Cloud monitoring”Real-time understanding of the maintenance and construction operations in the jurisdiction

Acousto-optic alarm cone，Adopt double flash light group warning and warning sound of more than 100 watts.，The visual distance of the flash lamp is more than 800 meters.，Sound can be effectively transmitted for more than 100 meters in the highway environment.，The whole machine can work in rainy days.；It can set up effective sound and light warning outside the safe distance behind the construction and accident site at the fastest speed.，The defect of insufficient warning during construction is overcome.，And the safety guarantee of maintenance construction is improved.，At the same time, it also ensures the safety of vehicles.。

The acousto-optic alarm cone barrel plays a double warning role in hearing and vision.

Next step，Engineering companies will continue to promote high-speed maintenance“Four new”Technology application，Strict implementation of safety maintenance operation guarantee，Comprehensively promote the construction of modern highway maintenance，Improve highway maintenance capacity，All-round and three-dimensional promotion“Intelligent maintenance”Construction。
