Textual content description offered by the architect SCSJ
Wuchazi bridge is situated alongside the Jin River within the Southern A part of Chengdu Hello-tech Zone, which is a vital pedestrian bridge connecting Guixi and Zhonghe sub-districts on this space. This municipal pedestrian bridge adopts the structural type of metal field girder and metal field arch, its whole space is 4180㎡. The design notionoriginates from the conception of “infinite ring” – the Mobius. We abstractly undertaking the infinite formin four-dimensional house into three-dimensional house, forming the icon of infinity in arithmetic. This icon represents the limitless improvement prospects of the Chengdu Excessive-tech Zone the place the bridge is situated.
By way of construction, the bridge physique is split into most important bridge and auxiliary bridge. The principle bridge is 346.89m in size and 4.65m-9.88m in width connecting greenways on each side of the river for biking. Whereas the auxiliary one is 208.78m in size and 6m-14.53m in width the place there exist the crescent-shaped theater steps for the river surroundings, offering a distinct house expertise for the general public. So far as the evening scene lighting, designers simply did concise atmospheric trendy floodlighting to focus on the distinctive form of this bridge, hoping to current a distinct landmark over Jin River.
Bridge construction: Wuchazi bridge is split into two components. The upstream bridge is the primary bridge, and the downstream bridge is the auxiliary bridge. These two components are linked by channels. Particularly talking, the primary bridge has two sections. The primary one is a two span steady metal field girder bridge (27m+27m), whereas the second is a 4 span slant legged inflexible body bridge (28.5m + 75.347m + 84.152m + 44.73m) to satisfy the navigation and flood discharge necessities. The auxiliary bridge adopts metal construction and is designed as three spans. The primary and second spans are special-shaped metal field arch bridges with spans of 59.166m and 84.431m respectively, which meet the necessities of navigation and flood discharge. The third span is inclined legged inflexible body construction with span of 41.673m.
Bridge size and width: the whole size of the primary bridge is 346.891m, and the width is 4.654m ~ 9.88m. The overall size of the auxiliary bridge is 208.781m, and the width is 6m ~ 14.533m.
Most span of single span: the utmost span of single span is the second span special-shaped metal field arch of auxiliary bridge with span of 84.431m.
Bridge top: the primary bridge girder is variable top, the minimal top is situated on the highest of Z2 pier, and the vertical top of the beam is 1.0m; the utmost top of the beam physique is situated on the axis z4-1 (inclined leg Zx1), and the vertical top of the beam physique is about 2.4m. The peak of the primary arch ring of the auxiliary bridge is 1.5m, and the vertical top of the third span beam is 1.3m ~ 1.5m. The beam top of hydrophilic platform is about 2.15m.
