Digital construction technology
Introduction of Sichuan Shuangliu Airport
3DDigital intelligent shop control technology
Mid-October 2023，The upgrading project of Shuangliu Airport, which was constructed by Sichuan Airport Road, was formally introduced.3DDigital intelligent shop control technologyThat isTopcon 3D mmGPSPaving control system，Mainly used forA2、A3 Water stabilization operation of upper base course，And on the first day of investment，Smooth、High-quality completion of paving construction with an area of about 6500 square meters。
3DThe digital intelligent control technology is formally put into use in this project.，It indicates that Sichuan Airport Road provides a new scheme and new ideas for the application of digital construction landing of civil aviation airports.。3DDigital intelligent paving technology is to install automatic control system airborne equipment on the traditional Paver.，Through the system supporting software and hardware solutions，Converting the traditional artificially controlled construction design data into engineering machinery that can be read、Self-identified data，And then control that machinery to automatically complete the paving construction operation.，It's like the control brain of a mechanical construction unit.，Pavement water-stabilized base course meeting the construction design requirements is paved by the screed of the automatic control Paver.。

3DApplication effect summary of digital intelligent shop control system
To ensure accurate control of paving flatness and construction elevation，Complete the implementation of the project with high quality，Sichuan field road is bold in innovation、Explore and try，Will 3DDigital intelligent control technology has been successfully applied to the upgrading project of Shuangliu Airport.。The person in charge of site construction said，Fully feel and experience the convenience brought by this new technology，The specific summary is as follows.。
01
High accuracy of elevation control
Compared with the traditional water-stabilized paving technology,，Topcon 3DPaving techniques do not require pulling wires、Setting out，A large amount of manpower and material resources can be saved.。The millimeter-level elevation control accuracy of the system provides high-precision elevation datum for the whole construction process.，It can accurately control the thickness of each layer of water-stable paving.，Reasonably control the material consumption，Avoid waste of quality materials，Thereby saving financial resources。
02
Process construction control
And reduce that artificial control error.，Improve the accuracy of base paving，Real-time monitoring of construction data，Repair in real time，From the original result detection to the current construction process detection，Improve construction quality and efficiency，Leveling with the cloth provided by the Paver，Fully automatic mechanization and good effect。
03
Process-based operation
Systematization of system operation、Process-based，The equipment is simple and easy to use，It is easy to find out the possible problems through the design of office data.，The engineering quantity can be accurately calculated by comparing the design data with the measured data.。
04
Construction digitization、Automation
The technology enables all-weather operation，Achieve real-time management、Precisely controlled construction mode，It will greatly improve work efficiency.、And that construction period is shorten。
05
Low-carbon construction，Safety and environmental protection
3DEfficient operation of the paving system，It can significantly improve the construction efficiency.、Save fuel consumption and personnel input, etc.，It can effectively reduce carbon emissions in construction operations.，Responded positively to the country“Double Carbon”Strategic policy。According to official statistics from Topcon，At the present stage, due to the global construction projects, 3.DTopcon with mechanical control system as the main bodyICTIntelligent construction system，Reduce carbon emissions by about 600,000 tons/Year。
The application of the upgrading project of Shuangliu Airport“3DDigital Smart Shop”The technology is mainly used forATaxiway andA3 Water stable paving of base course on taxiway，The total area is about 46,000 square meters。By applying 3DPaving technology and other digital construction technologies，Daily maximum pavement concrete pouring up to2500m³，On November 7, the concrete pouring of the west runway was completed 8 days ahead of schedule.，On December 7, all concrete pouring in the west flight area was completed 12 days ahead of schedule.，The overall progress has created a new construction speed for non-stop construction of airports with the same volume in the industry.。
December 8，Sichuan Road Organizes 2023 Technical Exchange Meeting and Symposium for Technical Leaders。The meeting was held“Scientific and technological innovation、Technical Management、Digitize、Intelligent construction”As the theme，Focus on sharing the company's technological innovation achievements in recent years。Secretary of the Party Committee of the company、Chairman Hu Mingliang，Chief Engineer、Deputy General Manager Zhang Hongyuan，Chief Financial Officer Sun Limin attended the meeting.。
This meeting shared3DIntelligent digital paving、UAV aerial survey、Construction technology planning、GPS—RTKTechnology、Intelligent construction、Digitize、BIMTechnology applicationTechnical achievements in 12 aspects.，The direction of technology development is discussed.，It aims to help the company's technological innovation and transformation and upgrading.。
Zhang Hongyuan fully affirmed the achievements of various units in technical management and scientific and technological innovation.，And put forward new requirements.：First, pay close attention to the basic work of technology.，Improve the system and mechanism of scientific and technological innovation，Enhance the ability of independent innovation，Give full play to the leading role of technology；Second, do a good job in digital transformation.，Construction of characteristic digital platform，Improve system integration capability；Third, deepen the collaborative innovation cooperation between industry, University and research institutes.，Promoting the construction of innovation platform and personnel training。
After the completion of the upgrading and renovation project of Shuangliu Airport, the damage of the runway surface in the West Flight Area will be eradicated.，Completely change the damage and aging problems of the infrastructure in the west flight area of Shuangliu International Airport，Effectively enhance the province's air passenger carrying capacity，Highlight“Sichuan Field Road”Brand strength，Help Chengdu Shuangliu International Airport to fly as soon as possible，Resume navigation and put into operation，To create a new pattern of opening up in Sichuan and the construction of the Chengdu-Chongqing economic circle。Next step，Sichuan Road will continue to focus on construction“Digital Field Channel、Wisdom Field Road”，Steady and far-reaching development on the road of high-quality transformation and upgrading。
