DILMUNIA GRAND CANAL & MARINA (DGCM)

Problem

Ithmaar Development Company is developing the reclaimed island of Dilmunia on the north-eastern coast of the island of Muharraq, Kingdom of Bahrain. The development project includes the construction of a nearly 1.5 km leisure canal (Dilmunia Grand Canal), which will be the central attraction of the island’s architectural design, including water activities, fountains, cascades, and waterfalls. Dilmunia canal is elevated few meters above the surrounding ground level, and any potential leaks may become visible and are highly undesirable. Therefore, the project foresees to waterproof the canal structure with various geosynthetic products, including several complementary watertight and drainage elements either installed inside and outside the peripheral walls. 

Solution

The construction of the Dilmunia canal is the object of an international Tender. The tender design for the waterproofing works has been developed by the engineering firm ARTELIA by specifying the following Maccaferri products for waterproofing & drainage functions. (1) Macline SDH 200 as the primary waterproofing layer inside the canal structure which will be retained at the upper perimeter by heat-seaming (welding) over an embedded anchor profile of ‘E’ locks and covered by 100 mm thick polymer reinforced concrete panels, (2) Macline N80.1 geotextile cushion layer intended to protect the geomembrane from damage during casting of the concrete panels, (3) Macline GCL W10 as the secondary liner designed to provide an additional watertight barrier against unexpected leakage, (4) Macdrain M120M as the drainage layer behind the concrete wall and (5) Macgrid WG 13S geogrid for ground improvement below bridge foundation structures. Maccaferri Middle East was involved in the design, supply, and construction assistance of the project.

Used Products

聚合物土工膜
聚合物土工膜
塑性土工膜属于合成土工膜的一种,以片(5-8m)为数量单位供应,厚度一般 0.5 至 3 mm。 尽管制造工艺可能不同,但都具备非常小的渗透性,适用于衬里和防水应用。 比较常见的聚乙烯,得益于其耐化学性、耐用性和低成本,其他高密度质量的使用也较多。View

GCL膨润土毯
GCL膨润土毯
GCL膨润土毯是通过在两个土工布之间耦合(通常通过针刺工艺)具有特定的膨润土层作用的复合材料。 这种复合材料在浸水后具有非常低的渗透性,用于建造地质保护和防水系统。 这种复合材料还可以与聚合物薄膜或薄膜层压,提高其耐用性并降低渗透性以适应更苛刻条件的工程应用。View
