Covered bridges fly across the road - the covered bridges in the Jiangsu Garden Expo Park Scenic Spot were successfully installed!

(Summary description)The green mountains are faintly sparkling, and the autumn is full of colors in the south of the Yangtze River. In Jiangsu Garden Expo Park, all seasons are good seasons. "Forever blooming" is the vision of the Garden Expo Park. Since the park opened in April this year, the Garden Expo Park scenic spot has become a new landmark in Nanjing and a place for Internet celebrities to check in. The former mines, valleys and ecological scars have become a fusion of Chinese architectural culture. , landscape gardening, cultural tourism and other multi-functional "world-class mountain garden group". 继去年参建园区各精品酒店、城市展馆和前期配套设施的钢结构工程后,日前,公司又迎来了后续配套工程——园博园景区与阳山碑材空中廊桥钢构的安装。
该工程包括垂直电梯井钢结构与空中廊桥钢结构,项目的难点在于空中廊桥的安装,廊桥为大跨度钢桁架结构,跨度63米,一端位于山顶基础,另一端支撑在距谷底地面62米高的电梯井顶端支座上。由于施工场地本身就位于一片狭小的缓坡之上,一侧临山,一侧临坡,可利用的场地极为有限,常规的桁架整体提升无法选择。经过多次方案比选,项目部确定了“单榀桁架整体吊装、上下弦杆高空连接”的思路,由于单榀桁架重达55t,且现有的电梯井钢结构和施工塔吊在空间上也制约了主吊机的选择,方案最终选用了600t履带吊,90米主臂的超起工况。
整个施工过程中,项目部陆续克服了大型履带吊进场及空中接杆、大跨度桁架组装及吊装变形控制、狭小谷地大型履带吊310度回转及超起工况带负荷行走等施工难题,施工过程顺利圆满。在钢结构施工完毕后,项目部将继续进行幕墙工程的施工,并计划在春节前完成该项目的施工任务。
该项目连接通道建成后,将成为园博园景区的又一新地标,使得相邻两景区无缝对接、自由切换。“锦绣江苏”的壮美画卷在山下绵延铺展,“阳山碑材”的恢宏气势在山上厚重盈荡。山顶眺望,城市园林错落有致,南京园“景阳楼”,领六朝烟雨,临渊矗立;阳山碑石横卧,静掩大明沧桑风云。正如山谷中工业遗存改造而成的“南京时”,代表着南京的过去、现在和未来,在这里,可感怀时空变幻,品味苏韵悠长。

Information

 

 

The green mountains are faintly sparkling, and the autumn is full of colors in the south of the Yangtze River.In Jiangsu Garden Expo Park, all seasons are good seasons. "Forever blooming" is the vision of the Garden Expo Park. Since the park opened in April this year, the Garden Expo Park scenic spot has become a new landmark in Nanjing and a place for Internet celebrities to check in. The former mines, valleys and ecological scars have become a fusion of Chinese architectural culture. , landscape gardening, cultural tourism and other multi-functional "world-class mountain garden group".

 

 

    After participating in the construction of the steel structure projects of various boutique hotels, city exhibition halls and previous supporting facilities in the park last year, the company has ushered in the follow-up supporting projects - the installation of the steel structure of the Garden Expo Park Scenic Area and the Yangshan Stele Material Air Bridge. .

 

 

The project includes the steel structure of the vertical elevator shaft and the steel structure of the aerial gallery bridge. The difficulty of the project lies in the installation of the aerial gallery bridge. The gallery bridge is a long-span steel truss structure with a span of 63 meters. On the top support of the 62-meter-high elevator shaft. Since the construction site itself is located on a narrow and gentle slope, with one side facing the mountain and one side facing the slope, the available site is extremely limited, and the conventional overall lifting of the truss cannot be selected. After several comparisons and selections of plans, the project department decided on the idea of "single truss overall hoisting, upper and lower chords high-altitude connection", because the single truss weighs 55t, and the existing elevator shaft steel structure and construction tower crane are not enough in space. Restricting the choice of the main crane, the plan finally selected the 600t crawler crane, the super-lifting condition of the 90-meter main boom.

 

 

    During the whole construction process, the project department successively overcame construction problems such as the approach of large-scale crawler cranes and aerial connecting rods, the assembly of large-span trusses and the control of hoisting deformation, the 310-degree rotation of large-scale crawler cranes in small valleys, and the walking with load under super-lifting conditions. The process went smoothly and successfully. After the construction of the steel structure is completed, the project department will continue the construction of the curtain wall project, and plans to complete the construction task of the project before the Spring Festival.

     After the connecting passage of the project is completed, it will become another new landmark of the Garden Expo Park Scenic Area, enabling seamless connection and free switching between the two adjacent scenic spots. The magnificent picture of "Splendid Jiangsu" stretches down the mountain, and the magnificent momentum of "Yangshan Stele Materials" is thick and swaying on the mountain. Viewed from the top of the mountain, the city gardens are scattered in an orderly manner. The Nanjing Garden "Jingyang Tower", leading the six dynasties of mist and rain, stands in Linyuan; the stele of Yangshan is lying on the side, quietly covering the vicissitudes of the Ming Dynasty. Just like the "Nanjing Time" transformed from the industrial relics in the valley, it represents the past, present and future of Nanjing. Here, you can feel the changes of time and space and taste the long history of Su Yun.
