China-Africa Salon: A stadium in 2 years, a bond of 42 -- Chinese builders share their Kenya story_我的网站

(Xinhua/Han Xu)In Nairobi, a 60,000-seat football stadium is entering the final stage of construction. Built in just two years, the Talanta Stadium will serve as the main venue of the 2027 Africa Cup of Nations, co-hosted by Kenya, Uganda and Tanzania.
"The schedule was extremely tight -- just two years, while comparable projects elsewhere usually take more than three," Du Xiao, project manager of the stadium for China Road and Bridge Corporation (CRBC), told Xinhua in a recent interview. "There is a very real sense of pride."
According to Du, the stadium has no running track, bringing spectators close to the pitch. Its seats take on the green, red and black of Kenya's national flag, while the facade features the traditional shield and spear of the Maasai people.
Upon completion, the stadium is set to be renamed the Raila Odinga International Stadium, in honor of Kenya's late former Prime Minister Raila Odinga.
The roof adopts a cable-supported grid system erected with a "cable-first, steel-after" method, which Du said is the first of its kind independently designed and built by China. Without temporary steel supports, 48 radial cables are tensioned to lift six ring cables before steel trusses are laid on top, saving at least three months of construction time, with displacement controlled to the millimeter. In 2025 alone, some 1,300 containers of materials and equipment were shipped from China to the site.
For CRBC, the stadium is only the latest chapter of a much longer story. The company built its first road in Kenya in 1984, and over 42 years, its footprint has extended from roads to bridges, ports, railways and buildings.
Du Shan, the executive general manager of CRBC Kenya office, recalled that before 2008, Nairobi was cut apart by three rivers and a cross-district trip could take more than three hours. After CRBC completed the ring roads, the journey now takes about 50 minutes. The company is also expanding the A8, a national trunk road, from two lanes to four and six, she said.
On the Mombasa-Nairobi Standard Gauge Railway, wildlife corridors were built with a clearance of more than six meters, "so that giraffes can pass with their heads held high," Du Shan said.

(Xinhua/Han Xu)Du Xiao arrived in Kenya in August 2011 and has worked on the ring roads, the Mombasa-Nairobi railway, the Nairobi-Malaba railway and the Nairobi Expressway before taking on the stadium project.
"Working overseas, we should not arrive thinking about changing the place. We should first adapt to and learn from the local community," he said. "What many projects truly open up is not just roads and railways, but trust between people."
The stadium sits near Kibera, Kenya's largest informal settlement. Du Xiao remembers a local young man named Sammy, who had no skills when he applied for a job but volunteered for the project's equipment training and became a pump truck operator. "I asked him why he worked so hard. He said, 'I never thought I would have the chance to touch these machines. Now I feel I can support my whole family.'"
According to Du Shan, the project recruited nearly 500 young workers from the neighborhood during construction, many of whom have qualified as assistant engineers, while about 280 local youths were mentored into technical backbones during the construction of the Mombasa-Nairobi railway.
More than 350 CRBC employees have worked overseas for over a decade, and each year the company awards them a gold medal for long-term dedication, she said. "The medal is not only an honor, but also a kind of warmth. Because 42 years -- it has truly not been easy."
When his child was born, Du Xiao was at a critical stage of the Nairobi Expressway project and could not make it home. "People in overseas engineering live in two worlds -- the project site on one side, the family on the other. All you can do is try to do a little better on each side," he said.
"Maybe I will one day leave this country. But this stadium will remain," he said. "I came here to build projects. Then I found that this country has shaped who I am today." 
。桩基施工在不影响地铁正常运营的前提下，攻克高密度运营地铁邻近施工难题，为后续西丽枢纽国铁站房主体工程施工奠定基础。　　据介绍，新建深圳西丽站坐落于深圳市南山区，总建筑面积91.44万平方米，核心建设内容为“一站多场一平台”，包含13台25线主站场、东西站前广场等设施，同步配套建设轨交、市政、商业等相关设施。该项目是国内首个高铁上盖绿色生态公园，也是国家级站城融合TOD示范工程；建成后将形成“4高铁+2城际+4地铁”多层次立体轨道交通网络，可带动深圳铁路客运整体运力提升约40%，对完善粤港澳大湾区综合交通格局、赋能区域高质量发展具有深远意义。　　深圳地铁13号线自2025年12月28日通车以来，保持着行车间隔不足5分钟、日均客流50.1万人次的高密度、大客流运营状态。中铁七局深圳西丽站3标119根线间工程桩均为地铁13号线运营期施工，项目面临施工空间狭小、安全风险极高、零运营干扰、施工精度严苛的多重挑战。

三 | 运营期涉铁桩基施工要求极为严格，全程保障轨道交通结构安全与行车秩序，是新旧枢纽工程衔接建设的关键核心工序。　　面对复杂工况与严苛要求，项目团队创新采用“全回转钻机下护筒、取土+气举反循环钻机钻岩”组合工艺，并同步搭建智能化立体监测体系，实现对既有地铁结构的亚毫米级实时监测、动态预警与全程管控。
