A big country with heavy weapons | The "Trinity Power" super project Shenzhong Passage was successfully opened to traffic!

After 7 years of construction, the Pearl River Delta World Bridge Shenzhong Passage Main Line Project was officially opened to traffic on June 30, the scene, the "long line" general vehicles in order, mighty and mighty, just for the first time to feel the shock and majesty of this super project.

The Shenzhen-Zhongshan Corridor is a cross-sea cluster project connecting Shenzhen to Zhongshan and integrating "bridges, islands, tunnels and underwater interconnection". The project adopts the East Tunnel and West Bridge scheme, with a total length of 24 kilometers, two-way eight lanes, and a design speed of 100 km/h, which is currently the most difficult cross-sea cluster project in the world.

Sany, as one of the main construction machinery brands of the whole project, has more than 10 Sany pump trucks and more than 10 Sany pump trucks in this world-class tunnel, island and bridge cluster project with a total investment of 46 billion yuan.Mixer trucksStationed all year round. In March 2020, when the project progressed to the most difficult and important construction stage of the bridge foundation - the pouring of the cable tower cap, it was selected by the contractor and all of them were contracted by the "World Pump King".

During the period, the project needs to complete more than 5098 cubic meters of C45 concrete pouring construction, which is equivalent to more than 4 swimming pools, due to the high temperature at the project site and the strong sea breeze, once the speed is too slow, it will cause uneven concrete solidification, which will lead to cracking. After 72 hours of uninterrupted operation, Sany pump trucks completed the pouring of the first bearing cap of the world's largest span mid-sea suspension bridge at one time, setting a new record for offshore construction. This extreme construction has laid a solid foundation for the early breakthrough of the Shenzhen-Zhongshan Corridor, and also left a strong mark of "Trinity Power" in the history of this super project.

During the construction, Sany pump truck performed excellently, without any failure in continuous and high-intensity operation, and its construction time was shortened by nearly 10% compared with the plan while ensuring the construction quality. Such an outstanding performance, thanks to the strong R&D strength and leading manufacturing level of the "World Pump King", makes Sany pump truck have good stability and reliability even in the harsh working environment and complex engineering requirements.

★ Advantage 1:Flexible fabric without dead corners

For the complexity of the construction environment of the project, Sany pump truck can easily achieve 360° full flat construction, break through the performance ceiling of concrete pump truck, and the cloth has no dead ends, so that the construction has no dead ends.

★ Advantage 2:Golden power, energy-saving upgrade

With a new power chain, relying on the four core technologies of engine hardware optimization, power matching optimization, oil pump efficiency optimization, and driving behavior optimization, it saves fuel and money for customers; The bodywork adopts the intelligent fuel consumption management 3.0 system, which reduces the working speed of the engine by 300rpm, saves more than 0.1L of fuel per square of concrete, and reduces noise by 20%. According to the calculation of the operation volume of 60,000 cubic meters / year of the pump truck, the average fuel saving is 40,000 yuan/year.

★ Advantage 3:Intimate after-sales, no worries

Sany nanny-style one-stop maintenance and service, so that customers have no worries. One-click call, arrive within 24 hours, major project construction site, Sany after-sales service commissioner stationed throughout the process, at any time to ensure that Sany equipment in an excellent state to complete the construction.

With the official opening of the Shenzhen-Zhongshan Corridor, the travel time from Shenzhen to Zhongshan has been shortened to 30 minutes, allowing Shenzhen and Zhongshan to enter the "half-hour living traffic circle" simultaneously. Over the years, Sany has created one miracle after another, from the world's first circum-desert railway to the world's largest span suspension bridge have imprinted Sany's footprints.

In the future, Sany will continue to uphold the mission of "Quality Changes the World", contribute more Chinese strength to global infrastructure construction, and write a more brilliant chapter.
