The early hours of the morning were supposed to be silent.，The airport in Xishuangbanna, Yunnan, is a hot construction atmosphere.，The construction team with more than 20 sets of Wirtgen Group pavement equipment as the main force gathered here.。
Within the construction window of less than 5 hours，Eight Wirtgen Milling Machines are arranged one after another.，Milling and removing the old asphalt pavement；Six Vogler Pavers cover the full width of the runway，A plurality of Road Rollers are followed by reciprocating rolling。
Behind the equipment team, the dense and smooth new asphalt pavement is slowly spreading out.，Since November 1, the asphalt cover test section of the airport runway has been successfully paved.，Yunnan Xishuangbanna Airport Phase IV Reconstruction and Expansion Current Situation Runway Cover Project Enters Formal Construction Stage，This is the scene of the airport in the early morning every day.。（Click on the video to view the high combustion picture of the construction）
The airport is not closed
Full-thickness full-section milling and paving of runway
The runway part of the Xishuangbanna Airport Phase IV reconstruction and expansion is the current runway cover project.：That is, the status quo runway.、Runway shoulder、After the original asphalt layer of the anti-blowing terrace at the north end is milled,，Covered asphalt concrete pavement，SatisfyERequirements for the use of class aircraft。
Full thickness required due to old asphalt layer on runway、Full width、Full face milling removal，After that, three layers of asphalt concrete are paved and compacted.，Relates to the length of the working face runway 2400 Meters，Width 60 Meters，It is estimated that the total paving volume will exceed 160,000 square meters.。In order to ensure non-stop navigation，Construction can only take place in a very short window in the wee hours of the morning.，You can imagine the pressure。This is for the overall planning of the construction team.、Full coordination and performance of construction equipment、Reliability and efficiency are solid tests.。
Fighting a tough battle depends on strength
Daily advance6000Square meters
Time is tight、The task is heavy，In order to ensure the smooth development of the work,，All departments of the ConTractor cooperate with each other，Plan ahead，Orderly organization。Before paving in the test section，Each unit has also organized safety education and training for construction team members.，At the same time, fire fighting was carried out many times.、Repair of cable damage、Cover mechanical approach simulation、Large mechanical fail-over、FODEmergency drills such as prevention；Asphalt Mixing Plant and Milling Machine、Paver、Rollers and other mechanical equipment have been maintained in an all-round way.，Ensure that the man-machine materials meet the commencement conditions。
A total of 200 construction personnel are put into the project The rest of us，Construction machinery 100 More than cars，The selection of main pavement construction equipment，After several rounds of investigation and evaluation,，Finally, Wirtgen Group pavement equipment is used as the main force.，Including 8 Wirtgen Milling Machines、6 Vogler Pavers、Several Hummer double-drum Road Rollers, etc., totaling 20 More than equipment，Give full play to synergy。
In the wee hoursLess than 5 hoursWithin the effective construction window period，Wirtgen Group Road Equipment Team lives up to expectations，Set an averagePush 6000 a day Square metersGood results，It fully demonstrates the high reliability and excellent performance of the equipment.。
Precise control
Solid quality guarantee
Construction site，Project team members perform their respective duties，Operate in strict accordance with the standardized process。Traveling speed of the construction personnel to the milling machine、Milling depth、Paving temperature、Paving thickness、Paving speed、Rolling temperature、The key technical parameters such as rolling speed and process are accurately controlled.。At the same time，Surface flatness of paving layer、Rolling and elevation after rolling are comprehensively monitored.。
It is worth mentioning that，In the construction process，Paver is the main factor to determine the quality of the surface and the construction schedule.。The paving site consists of 6 sets.Vogler Universal Paver Super 1880 L Take on this important task，There is no difference in the construction effect between the paved surface layer and the large paver of Vogler's high-grade pavement in terms of key indicators such as flatness.，Maintaining Fogler's consistent high standards，The project has been recognized by many parties.。
At present, Xishuangbanna Airport Phase IV reconstruction and expansion project has entered a comprehensive sprint stage.，The planned project duration is 75 days.，It is expected to be completed by March 31, 2024。Coming up，The project department will follow the high standard of the plan.、High quality、Finishing the construction of runway cover with high efficiency，Wittgen Group equipment will also continue to contribute to the successful completion of the project with efficient and reliable construction advantages.，To provide a solid guarantee for the completion of the project on schedule。
