As China-Africa cooperation advances with the times、Continue to deepen，Stories of cooperation are playing out on the African continent.，China's construction machinery is also showing its elegance in Africa's infrastructure projects.。Recently，On the Roseau Bridge Project in West Africa，Zoomlion's rotary drilling rig has completed the pile-forming task efficiently and reliably，Steady Progress of Bridge Pile Foundation Construction，It has received unanimous praise for its high-quality products and services.。

It is understood that，The Rosso Bridge is located on the Senegal River at the border between Senegal and Mauritania.，It is the first large-scale project jointly constructed by the two countries.。After the completion of the bridge, it will become an important hub of Africa's transnational trade trunk line.，Greatly save the time of cross-border travel between the two countries，Facilitate the exchange of personnel and materials。

To protect the local environment，The Owner prohibits the use of chemical slurry for wall protection.，Because the local stratum is fine sand.，The rotary drilling rig cannot form a pile due to the risk of collapse.，The customer originally planned to use a disposable casing and a vibrating hammer to form a hole.，But the cost is too high.，After comprehensive consideration and comparison，The hole-forming method with full rotation and casing is adopted.，Casing can be reused to reduce cost，The widely acclaimed Zoomlion rotary drilling rig was selected for construction.。

Since the equipment entered the site in February this year,，The service team of Zoomlion quickly completed the operation training for local construction personnel.，Ensure that African workers are skilled in the use of full-swing drilling rigs。“European standards introduced in Africa ban the use of chemical mud，Full casing process is used a lot here.，The full-swing drilling rig used this timeZRT260H，An experimental pile was driven at the request of the client，Down 55 meters of casing，Pile depth 52 m，Quickly put the crawler crane to take the soil and form the hole。The customer commented that the machine is powerful.，Construction is stable，Depth under casing，Exactly what they expected.。”Tong Bing, an African resident service engineer of Zoomlion, said.。
