APTUM Architecture proposes floating concrete islands to repopulate mangrove forests

由专筑网Yumi,杨帆编译

Isla Rhizolith / Rhizolith岛屿是一个概念和项目原型,由APTUM建筑事务所与来自锡拉库扎大学的CEMEX研究组和学生共同合作完成。该项目调查了漂浮混凝土结构的潜力,使哥伦比亚城市区域中易遭受持续洪水的海岸线重获新生。作为对红树林生态不断遭受破坏的回应,保护被海岸线侵蚀的泥沙,项目通过强调新开发的混凝土材料、形式表达与性能,重新定义城市基础设施。

Isla Rhizolith / Rhizolith island is a concept and prototyping project presented by APTUM Architecture in collaboration with CEMEX research group and students from Syracuse university. The project investigates the potential for floating concrete structures to revitalize Colombian shorelines among urban areas vulnerable to ongoing flooding. In reaction to the continued destruction of mangrove forests that naturally protect sediment and shorelines from erosion, the proposal aims to redefine urban infrastructure through emphasis on newly developed concrete materials, formal expression and performance.



Rhizolith是一个包裹在矿物质中的根系统——通过侵蚀和胶结的过程而产生——保护和加强土壤的自然成分。Rhizolith岛屿由APTUM建筑事务所和 CEMEX提出,它是一个防波堤系统,包括“根状”的混凝土元素和种植的红树林,将该设置漂浮在水上,充分实现了人工与自然的结合。

A Rhizolith is a root system encased in mineral matter — created through processes of erosion and cementation — that protects and strengthens the natural composition of the earth. The Rhizolith island proposed by APTUM Architecture and CEMEX is a breakwater system comprised of ‘root-like’ concrete elements and planted mangroves that, when set floating upon the water, act as both an artificial and natural Rhizolith.

一旦生长,该结构将免受洪水的侵袭,同时好比一粒种子,起到对新的红树林的振兴和保护作用。持续的城市增长、农耕、飓风以及哥伦比亚海岸线每年爆发的洪水,都使得极大程度上的植被与生境丧失。该方案反映出我国沿海城市的现状,而且,这样才能扭转不幸的后果,创造一个更安全、更具弹性的基础设施,让我们的城市可以更加繁荣地发展。

Once growing, the structure protects from flooding and acts as a seed for the revitalization and protection of new mangrove trees. Continuous urban growth, agriculture, and storm surges all contribute to devastating amounts of vegetation and habitat loss, as well as annual flooding along the shoreline of Colombia. The proposal reflects on the current state of our coastal cities but also on that which can be done to reverse these unfortunate consequences and create a safer, more resilient infrastructure through which our cities can thrive.

元素是由两个单独的片段构成的;一个“头”和一个“鳍”,都用专有的混凝土混合料和铸造技术制成。头部是由混凝土的混合物制成的,它比水轻,即使外壳有洞也能够照常浮动。此外,通过混凝土,轻质混凝土的弱混合料让红树林的根部随着时间的推移而生长。“鳍”,另一方面,是由UHPC(超高性能混凝土)制成的。它的重量和强度使水中的元素稳定,还为海洋生物的栖息地提供基座,提供遮蔽处和表面让附着甲壳动物生长。

The elements are constructed out of two individual pieces; a ‘head’ and a ‘fin’, both made with proprietary concrete mixes and casting techniques. The head is made from a concrete mixture that is lighter than water, allowing it to float even if there are holes in the shell. In addition, the weaker mixture of the lightweight concrete allows the roots of the mangroves to grow through the concrete over time.
The ‘fin’, on the other hand, is made from UHPC (ultra high performance concrete). Its weight and strength stabilizes the elements in the water and provides the basis for a marine habitat by offering shelter and surfaces for barnacles to grow. To protect the elements from each other, a rubber ring is cast into the top of the head. Steel grommets embedded in the rubber allow the elements to be sewed together with rope into larger aggregations.

Rhizolith岛屿是较大的防波堤的片段,可以沿着海岸线部署一系列的战略位置,这里受干枯的红树林和每年洪水的影响最大。同时,鳍元素作为稳定剂,创建诱人的生态系统,类似于落叶层和分解物,成为动植物栖息的结构。在第二阶段,红树林将继续在漂浮元素以及陆地上生长,实现海岸线树木的进一步生长。

在最后阶段,漂浮元素将最终沉入海底,以减少额外的侵蚀。该系统建立了红树林的局部恢复和扩展工作。  

The Rhizolith island is a fragment of a larger breakwater that can be deployed along the shoreline in an ‘acupuncture’ strategy in locations most affected by depleting mangroves and annual flooding. The porous concrete dissipates the force of the water during a storm surge. Simultaneously, the element fins serve as stabilizers and create inviting ecosystems, similar to leaf litter and decomposing debris, for flora and fauna to inhabit the structure. In the second phase, the mangroves continue to grow on the floating elements as well as on land, allowing for further growth of trees along the shoreline.
In the final phase, the floating elements eventually moor into the seabed to reduce additional erosion. This system establishes a local restoration and expansion of the mangrove forest.
