The first bridge in the Yunnan section to be poured this time is the Songming Caijiacun No.3 Bridge.，Located in Songming County, Kunming City, Yunnan Province，The main span continuous beam has three spans.，Parallel to the Shanghai-Kunming high-speed railway.、Overpass Rural Highway，The continuous beam is a reinforced concrete box beam，Beam face width 12.6 meters，Beam bottom width 5.5 meters，Support cast-in-place method is adopted for construction。Due to the particularity of the bridge structure and technology,，The pouring work shall be carried out continuously.。
To ensure the orderly progress of construction quality and progress，And ensure the underpass highway、Normal operation of adjacent high-speed railway.，The construction party has carried out many discussions and strict reviews on the comparison and selection of construction schemes.，The final choice is Zoomlion.“Ling Yun”Series 56 m、50 meters、Pump trucks of 49 meters and other meters take on this important task.。The pouring of the continuous beam was completed several hours ahead of schedule.，Perfectly meet the requirements of the construction party。

As one of the main pump trucks to complete the construction.，“Ling Yun”The 50-meter pump truck is praised by the industry as“The king of agility”，Adopt bionic six-section arm，Small footprint、The cloth is wide，Supported by the world's leading boom active damping technology，The boom amplitude under all working conditions is as low as±0.2 meters，It is equipped with dual independent hydraulic oil tanks.，Low consumption、Efficient、The operation time is long。
In addition，Several other concrete equipment such as Zoomlion Wet Spraying Machine also participated in the construction of the project.。

The project side said，The continuous beam of the bridge is the first continuous beam completed in the Yunnan section of the Chongqing-Kunming high-speed railway.，It means that the bridge is smoothly transferred from the lower part to the upper part.，It has won the opportunity for the continuous beam construction of the whole line.、Conditions have been created。In the process，Zoomlion Concrete Machinery provides strong support for the project，Its powerful performance is trustworthy.。
Chongqing-Kunming high-speed railway is an important part of the Beijing-Kunming corridor of the national eight vertical and eight horizontal railway network.，It is 699 kilometers long，Across Yunnan、Expensive、Chuan、Chongqing and other provinces and cities，The total length of Yunnan section is 388.Six kilometers，It is the first high-speed railway in Yunnan Province to operate passenger trains with a target speed of 350 kilometers per hour.，There are 53 tunnels in the section.，The ratio of bridge to tunnel is up to 87.4%。After the whole line is completed and opened to traffic，It will become the opening up of southwest China and the opening up of southwest China.“The Belt and Road”Convenient access to ASEAN，To promote the high-quality development of regional economy，It is of great significance to promote rural revitalization and national unity and progress.。
