Elastocoast® — 使我们的海岸和河流更安全
Elastocoast® 是一种新颖的智能聚氨酯系统 。Elastocoast®由两种用于海岸区域护岸工程灌浆的成分组成,即使巨浪在它面前也无可奈何。它的开放式气孔能够在潮水刚刚涌起时就吸收其破坏力。同时,它又是一种生态产品,涂敷后不久动植物就会重新回归。这种在许多海岸保护项目中经受住考验的材料同样也可以用来加固河岸。在此类应用中,这一系统也同样显示出其优势。以护岸层抵御潮水。Elastocoast®是海岸保护的理想护岸解决方案,也可用于恢复河流和堰的生态。
Elastocoast®用于海岸保护和河岸加固时的优点
- 提高海岸区域的安全性
- 开孔透气,透水
- 降低建设和维护费用
- 吸收波浪产生的力量
- 环保
- 稳定,经过多年实践检验

常规技术包含的刚性混凝土结构可能会受到波浪冲击,霜冻和地面沉降的破坏,而Elastocoast®系统则涉及将骨料(碎石)与环境相容的2组分聚氨酯塑料进行机械粘结。
Elastocoast®技术
•石头之间的多孔结构可承受强波冲击。
•覆盖层还为动植物群提供了栖息地。
应用领域
Experts predict that the sea level may rise by up to 50 centimeters in the coming years as a result of global warming. Of course, no scientist can foresee when and how this rise will actually occur – or the ultimate consequences. But it does highlight the obvious need to intensify coastal protection and flood prevention activities.

But it does highlight the obvious need to intensify coastal protection and flood prevention activities and particularly to raise the dikes.
Another dangerous scenario is dike overtopping, since subsequent erosion on the land side inevitably results in complete dike failure. This is where Elastocoast® opens up a totally new dimension in coastal protection.
在海岸保护中经受住考验的材料同样也可应用于河岸和运河。其目标同样是建立稳定的、接近自然的护岸工程,以便加固岸区,使之在承受航运和潮汐(例如易北河的情形)的压力时保持稳定。在建设航道时,还可进行水下施工,即将经过足够反应时间的石料与聚酰胺的混合料倾倒到近岸的水中并压实。其原理与用于堤岸建设的情况一样简单,即防止河岸边缘由于强水流的冲击而变得脆弱和受损。
The stones used have to be clean and surface-dry before being processed. This is a requirement that seems to be difficult at first sight. As other realized projects show, certain simple measures regarding handling and logistics eliminate this obstacle.
Elastocoast® consists of approx. 50% of vegetable fatty acid esters, thus renewable raw materials. In addition, due to the high porosity cavities it provides additional habitat for animals and plants. Also the Elastocoast® revetments easily integrate into the overall appearance of the landscape. Due to the transparency of the material, it is difficult to set them apart from naturally coloured rip-rap.
Before the material has completely cured, the surface should be covered with dry sand by which the visual effect is additionally adjusted and a skid resistant surface can be created.
Biological studies by the University of Amsterdam have shown that revetments with Elastocoast® are colonized by the flora and fauna typical of the local region within just a few weeks.
Unlike conventional, impervious coastal defense structures, Elastocoast® revetments with their cavities also provide additional habitats for the animal and plant world. And thanks to the transparency of the material, the revetment blends noticeably better into the local landscape.
To demonstrate the environmental impact and ecological benefits of new Elastocoast® technology, an extensive eco-efficiency analysis has been carried out. This involved a life-cycle analysis of various products and processes in terms of their impact on the environment.
The ecological assessment is based on DIN EN ISO 14040 and 14044 and has been certified by TÜV (Technical Control Board) Berlin as an overall method. Elastocoast® was compared to traditional coastal protection methods such as concrete and open stone asphalt (OSA) on a surface area of 20,000 m².
The most recent study (in 2014) of the Institute of Environmental Hygiene and Toxicology in Gelsenkirchen, Germany, has confirmed the safety of the PU system in coastal protection in terms of toxicology and environmental medicine.
Long-term monitoring and controls of stability, erosion resistance, recolonization, resistance to weathering and saltwater, and many other parameters have shown that Elastocoast® revetments already achieve top results on the decisive counts.
Hydraulic engineering structures are expected to have a life time of 20 years and more. All construction materials on inorganic (cement-bonded) or organic (plastics) basis are subject to the impact of weathering when used outdoor. Particularly damage caused by ultraviolet radiation, salt water and frost must be considered. PU materials are established in outdoor applications such as concrete and sports ground coating or offshore, oil and gas pipelines resisting salt water attack.
The degradation process that takes place in sea water was accelerated by increasing the temperature in small steps up to 80²C. In this way the results can be extrapolated back to 20-30°C. This extrapolation shows that the PU-material is fully stable in salt or sea water at service temperature of 20 - 30°C and it has a lifetime expectation of 80-100 years.
The TUHH provided evidence that there is a sufficient persistence when exposed to UV irradiation, tested in special developed water transition area equipment. The frost resistance is secured by tests in accordance with DIN EN 13383-2.
处理
在处理之前,必须将使用的石块清洁干净并干燥表面。这一要求初看之下好像很难达到。其他已经完成的项目显示可在搬运和物流方面采取简单的措施来满足这一要求。
Elastocoast®包含大约50%的植物脂肪酸酯,因此是可回收的原材料。此外,由于其腔体具有高孔隙率,所以可以为动植物提供额外栖息地。同时Elastocoast®护岸还可以轻松集成到景观的整体外观中。由于材料是透明的,所以很难将它们与自然色的抛石区分开来。
在材料完全固化之前,必须使用干沙将表面覆盖,这也是另外一种对视觉效果进行调整的方法,还可以生成防滑表面。
