赫爾河回轉人行橋(River Hull Footbridge)黑鐵色外觀、獨特的曲線樣態與可移動式的誤能,不但將赫爾舊城保護區和東岸的非工業景觀區連接起?,也形成了英國赫爾河上的地標和里程碑。

赫爾河回轉人行橋主要結構為一直徑約為16公尺可旋轉式的懸臂樑式橋台,在做為水利設施的同時,橋頂上的觀景台上也規劃了鋼制欄杆可供遊客倚靠觀賞美麗的河景,同時行人可站在橋上感受人行橋開關水道時轉動的感覺。人行橋利用鋼板材質構成行人走道,並可用來加強懸臂樑的強度;旋轉基台的重量則可與懸臂樑的重量相平衡,並在圓筒狀混凝土保護下的中央樞軸處由六個單輪及四個雙輪機構提供懸臂橋台的轉動。

赫爾河回轉人行橋提供了一條跨越赫爾河的行走路線,將西岸博物館區和東岸赫爾區的主要觀光景?The Deep相連,也有人說人行橋的功能就像是鐵道中的轉車臺一般。懸臂橋開始轉動時操作員會先關閉河岸東側的入口,而位於西側的人行橋入口則開放給行人自由進出。橋樑旋轉時的速度每秒低於0.15公尺(甚至比倫敦眼的速度還慢了一半),因此在旋轉過程中行人可於西側安全地進出行人橋並站在橋上與行人橋緩慢地的赫爾河上旋轉,而整個旋轉的過程大約是2分鐘左右。

西側的舊城保護區已由歐洲的Grontmij工程顧問公司重新設計景觀,一旁Scale Lane Staith街原本的停車場也改建成一系列的公園區直通河岸,以及一處擁有戶外座椅區的廣場,而原始由卵石舖成的Scale Lane Staith街在保持原貌下也加以重新舖設。

The original cobbles of the original staith have been retained and re-laid. A green wall of planting will provides a cohesive edge and screen the adjacent building once it matures. On the east bank, pending future redevelopment of the riverside site, a temporary ramped path has been laid which orientates pedestrians to Hull’s main visitor attraction The Deep.

The structure consists of a steel spine cantilevering around from a 3-dimensional braced ring structure approximately 16m in diameter. The spine is a hybrid structure with the ‘root’ section conceived as a diagrid/shell structure and the tip as a shell structure. Steel plates clad the surface of the walkways whilst horizontal bracing provides additional longitudinal stiffness. The ring/drum/hub structure consists of columns connected to horizontal steel “wheel” structures forming both levels of the 3D ring. The circular hub section acts as a counterbalance to the cantilever section, with heavy RC slabs at both levels of the 3D ring structure. Braced frames provide stability of the ring structure. The hub is supported vertically on a central pintle and six single / four double wheel assemblies running on a 16m diameter flat circular track, secured to a concrete drum supported on ten 1.6m dia. piles over 30m long.

The bridge is supported on a series of wheels running on a circular 16m diameter track below the hub, like a railway turntable. Three electric bevel gear units drive the bridge which pivots around a central slew bearing. The bridge is operated from a radio pendant. The whole sequence takes around 2 minutes. The bridge operator closes a gate at the East bank triggering the opening of the bridge. There are no barriers at the west bank so people can freely walk on and off while it is in motion. The speed of rotation at that edge is slow – less than 0.15m/sec, (less than half the speed of the London Eye) so can be stepped across safely.

The west bank of the bridge, which leads to the Old Town and is part of the Old Town Conservation Area, has been re-landscaped by Grontmij. A car park along Scale Lane Staith has been replaced with a series of informal ‘garden rooms’ stepping up to the river side.(with its increased flood defence level) and leading to a new paved square which will eventually provide space for al fresco seating for the restaurant.
