The surging Wujiang River flows eastward.，Wall rock towpath creates miracles。
On the Wujiang River，Changhong flying moat。Two huge red towers stand by the river.，A curved steel arch across the natural barrier，Outline a magnificent figure.，It is particularly eye-catching。
This is the Wujiang River Bridge of Deyu Expressway under construction in Guizhou.，Among them, the busy figure of Sany concrete equipment has become a beautiful scenery in the construction site.。
Wujiang River Bridge is 1834 meters long.，It is an important control project of Deyu expressway.，It is also the largest span deck concrete-filled steel tubular arch bridge in the world.。Its main span is 504 meters.，Than“Eye of Heaven”It's four meters in diameter.，Deck type steel pipe concrete technology，Fusion cable-stayed bridge、Suspension bridge and other complex technologies，New technology、The precision is high、Difficult to control，The construction difficulty is in the forefront of the same type of bridges in the world.。
The project is located in Fenggang, Guizhou.、Shi Qian、The junction of three counties in Sinan，Since the start of construction，It is difficult to build the construction road.、Difficult temperature control in concrete construction、There are many difficulties such as rainy weather for many days and epidemic prevention and control.，Seriously affect the construction progress of the project。Since the beginning of September.，Sany pump Truck relies on high efficiency、Safe、Reliable product performance perfectly adapted to the construction site environment，High quality for the bridge、High security、Provide strong guarantee for efficient construction，Press for Deyu expressway Construction“Fast-forward key”。
Pumping jacking method is adopted for Wujiang Super Major Bridge，From arch foot to arch crown，According to the designed pouring sequence in the transverse direction and longitudinal direction of the bridge“Three-stage relay perfusion method”Proceed。Arrange 3 pipes on each side of the bridge，Uninterrupted pouring is required on both banks for each construction，There can be no deviation.，No more breakdowns.。
To ensure that the project is on schedule，Three 28 MPa trailer pumps for Sanyi Pumping，A 28 MPa Truck-mounted pump has become the main force of the pumping mission.，It basically maintains a 24-hour uninterrupted working state.，The maximum amount of concrete poured in a single pipe is 800 cubic meters.。
Zhu Wei, the project manager of Hunan Sanjing Zhongbang Co., Ltd., who undertook the project, said.：“The whole project is technically complex.，The amount of construction is large、High difficulty and tight construction period，In addition, it has very strict standards and requirements for construction efficiency and quality.，And the concrete construction of most of our high-rise buildings here basically uses Sany's equipment.，So we still chose Sany equipment this time.。”
Time for this pouring task is tight.、The difficulty is high，24 hours uninterrupted construction of equipment，The challenge to the pump Truck is great.。“The quality of Sany pumping equipment is really reliable.，Strong adaptability，Efficiency can not be said，Performance、Durability rate、The failure rate is also very advantageous.，You did very well.。”The person in charge, General Manager Zhu, said with deep feeling.。
In this construction，With its consistent stability and safety, SANY equipment meets the harsh conditions of construction.，Excellent performance has won the high recognition of the project side.。
The Wujiang River Bridge of Deyu Expressway in Guizhou Province is the longest span deck-type concrete-filled steel tubular arch bridge in the world.，It is technically difficult.，It is a great challenge for the construction team and equipment performance.。
To ensure the construction period and quality，Sany staff escorted all the way.，Follow up the project progress in real time，Technical personnel were dispatched for on-site guidance at the first time.，Service personnel will also visit the project site regularly to check the operation of the equipment.，To ensure the smooth progress of the project.，Interpreting with action“By all means，Make the SANY service beyond measure”The concept of service。
Deyu Expressway is the only one in Guizhou Province selected as the first batch of the Ministry of Transport.“Ping An Centennial Quality Project”Road projects to create demonstration projects,It has entered the sprint stage of opening to traffic on schedule.，Wujiang River Bridge is one of the key control projects.。
It is reported that，After the completion of Wujiang River Bridge and the opening of Deyu Expressway，Will expressway with Hangrui.、Forming a composite interchange along the expressway of Germany，To promote the construction of the western demonstration province of Guizhou's transportation power，Promote the upgrading of industrial structure along the line、Development and utilization of resources、The development of tourism industry is of great significance.。
Sany will work hand in hand with all parties，Strive for the early completion of the bridge，The expressway will be opened to traffic soon！And continue to promote national development.，Zhuangxing Made-in-China contributes to the strength of Trinity！
