Topcon 3DMillimeterGPSPaving control system
Application in the project of Taihang Expressway
Bid 2 of Anyang Section along Taihang Line, undertaken by CCCC Second Highway Engineering Co., Ltd., successfully completed the paving of the experimental section of water-stabilized subbase。The paving test section is selected atK49+140～K49+600-segment left，It is 460 meters long，Paving width: 13m，Design thickness 18cm。
The water stability test section of the project adopts centralized mixing in the mixing station.，Paver paving。In order to ensure the successful paving of the water stable test section and achieve the expected results,，The construction general technical meeting of the project will be held in advance.，Yeah, measurement、Test、Technical and safety disclosure for equipment operation and other relevant personnel。During paving，Close cooperation of all departments，Field Technician、Surveyor、The tester tracks the whole process，And uses the latest Topcon 3DMillimeterGPSPaving control system，Through digital management，Full process control，Comprehensively improve the construction technology，Complete the paving work of the water-stabilized test section on schedule。
Paving site along the test section of Taihang Expressway
The smooth paving of the water stable test section provides a prerequisite for the construction of the pavement structure layer of the project.。The actual test results of the test section show that，Topcon 3DMillimeterGPSThe paving control system is used to increase the paving thickness of the water-stable layer.、Control related to construction design elements such as smoothness and transverse slope。
September 29，K48+580 toK48+Formal paving of water-stabilized base course of Section 000，Marks Topcon 3DThe application of the paving system in this project has officially begun.。
Formally pave the base course along Taihang Expressway in a water-stabilized manner

Jiang-Lu North Line
Topcon 3DIntelligent Paving Site Observation Meeting
To promote the professional level of pavement construction of CCCC First Highway Engineering Co., Ltd.，Creating highlights of pavement construction technology,Promoting the application of new technologies in the fourth project。September 15，CCCC First Highway Engineering Co., Ltd. organized the pavement construction technology quality exchange meeting and Topkom 3 in the second work area of Jiang-Lu North Line pavementDIntelligent Paving Site Observation Meeting。Technical Quality and Digital Department of the Company、Engineering Department of Production and Operation Center、Each pavement project，Road experts from the First Public Bureau and the company participated in the exchange meeting.。
This time 3DThe total length of the intelligent paving demonstration section is 800 meters.，A total of about 6000 tons of lower base mixture are paved.。To ensure the effect of the observation meeting.，On the one hand, the second work area of Jianglu North Line pavement is planned ahead of time.、Scientific deployment，Prepare the construction site organization plan in advance，Improve the site management system，Division of responsibility to people；On the other hand, debugging in advance，Launch Topcon 3DIntelligent paving test，Grasp relevant data in advance，Carry out man-machine running-in，Effectively ensures that 3DSmooth development of intelligent paving construction technology。
Conference communication link，Technical specialist“PPTProjection+Explain on the spot”The way of combination，Topcon 3DTechnical Characteristics and Process Principle of Intelligent Paving System、The promotion significance and development prospects are introduced in detail.，At the same time，The participants discussed the key points of quality control of pavement construction technology.、In-depth exchanges and discussions were conducted on the subject of pavement mix proportion and technological innovation.。
This time“Pavement Construction Technology and Quality Exchange Meeting 3DIntelligent Paving Site Observation Meeting”Smooth implementation，It not only promotes the digital transformation of the First Public Bureau in the field of highway construction.，At the same time, it further fulfilled the confidence and determination of the company as a central enterprise to resolutely implement the innovation-driven development strategy.。

Shuoshen Expressway
Topcon 3DIntelligent paving technology helps
Smooth paving of Shuoshen Expressway pavement project
In the near future，At the construction site of Shuoshen Expressway Pavement Project，Several for transmitting and receiving signals.“Mushroom head”The equipment is installed on the Paver for the construction of water-stabilized subbase.，Advance at a constant speed with the Paver，3DIntelligent paving automatic control system for the first time in Shuoshen Expressway No.1BSuccessful application of the contract section。In order to better apply this new technology to the construction site.，Shuoshen Company has made a preliminary investigation.，A lot of preparatory work has been done.，Timely convening 3DPaving site technical seminars and other professional meetings，And special training for technical personnel。The new technology adopted in this project 3DPavement paving control system，It is also Shuozhou、It is the first time to use this technology for pavement in Xinzhou area.。
Topcon 3D mmGPSPaving technology is based on satellite global navigation positioning system and laser high-precision measurement system.，Elevation accuracy and plane accuracy of three-dimensional control paving，Topcon Intelligent Pavement Paving Effect，It is called by the industry“Pavement 3DPrint”New technology！Flattening accuracy error can be controlled at about 3 mm。
At present, Shuoshen Expressway No.1BContract section uses Topcon 3DPaving technology completed the first section of pavement subbase paving.，The work content of survey and setting out is reduced，The thickness of the structural layer is well controlled、Elevation and flatness，Realized“Mechanized replacement、Automation reduces personnel”The idea of，Reduce the man-machine safety risk of the project，Speeding up the construction progress，And that production efficiency is greatly improve.，Accumulate valuable experience for that application of the technology。Follow-up projects will also actively explore the application of 3DSpreading+Unmanned rolling complete equipment、New technologies such as full-section paving of middle and upper courses。
The adoption of this technology in the project fully demonstrates the specialization of expressway construction.、Standardization、Digitize、Refinement level，Intelligent high speed has been built.、Quality and high speed，Facilitate better implementation“Quality Engineering”The goal of construction，Innovating and Promoting the Quality Improvement of Project Pavement Engineering。
