“Did you know that Shenzhen dismantled a flyover in just nine days?” This story isn’t about that specific flyover but it showcases the “Shenzhen Speed” that might apply to the 2# Flyover of Henglang Junction too.
Welcome to the 2# Flyover of Henglang Junction. It stands as a testament to Shenzhen’s rapid development.
Let’s talk about Shenzhen’s impressive infrastructure projects. The city is known for its efficiency. The dismantling of the Huangmugang Flyover illustrates this perfectly. The Huangmugang Flyover was a complex structure. It consisted of five bridges. Its total length was 1,544 meters. It contained 14,619 cubic meters of concrete. Dismantling it usually takes six months. Yet Shenzhen did it in nine days. This feat added a new chapter to the “Shenzhen Speed” legend.
How did they achieve this incredible speed? Rigorous preparation was key. Technicians spent one and a half months meticulously planning. They used Building Information Modeling or BIM. BIM is an intelligent 3-D model-based process. It helps professionals plan, design, construct, and manage infrastructure efficiently.
The team created a computer model. This model simulated the entire dismantling process. Every part of the flyover was numbered. Vehicle routes were specified. This ensured that cranes wouldn’t collide. The professionals conducted four rounds of scenario planning.
The dismantling involved 2,340 vehicles and equipment. About 30 cranes of different tonnage were used. Self-propelled modular transporters or SPMTs were vital. SPMTs are motorized vehicles. They move at walking speed. They can carry large structures like bridges. SPMTs positioned the bridge sections precisely.
The Huangmugang Flyover project used 240 axles of SPMTs. This was supported by 16 power pack units. This accounted for one-fifth of all SPMTs in China. It was the first time so many SPMTs were used in a Chinese construction project. Each SPMT axle can carry 35 tons of loads.
The SPMTs supported the bridges during cutting. They also carried concrete to designated areas. This was done in a controlled way. The flyover was tri-layered. Time was limited. SPMTs significantly cut time. They also ensured safety compared to manual methods.
The dismantling took place during the Chinese New Year holiday. Leaders from the Shenzhen Municipal Government visited the site. They greeted the workers. About 100 executives supervised the work. This ensured safety and quality. Workers received four meals a day. They even had dumplings on Chinese New Year’s Eve.
The renovated roads and intersection were put into service quickly. The area became a transport hub. It integrated Metro lines 7, 14, and 24. Like the Huangmugang Flyover, the 2# Flyover of Henglang Junction plays a crucial role. It ensures smooth traffic flow in Shenzhen. It is a vital part of the city’s transportation network.
So, as you traverse the 2# Flyover of Henglang Junction, remember the “Shenzhen Speed”. It’s a symbol of the city’s relentless progress. It showcases its commitment to efficient infrastructure.
