Cairo Metro – Line 3

Cairo Metro – Line 3

Since the first 29km segment of the Metro Line 1 opened in 1987, the Cairo Metro project has revolutionized the transit system in the capital.
Currently the whole network comprises 3 operational lines numbered from 1 to 3. Line 3 consists of four phases, and the first segment started operation in 2012.

Three new metro stations were opened as part of the fourth phase of the third line on June 15, 2019, a week before the kickoff of the 2019 African Cup of Nations (AFCON) in Cairo.

Dextra has continuously provided construction solutions since the operation of Line 2 in 2000, delivering since then more than:

-1,400,000 rebar couplers

-7,000 sonic tubes

-60 soft-eyes

Bartec rebar couplers are used for rebar reinforcement of tunnel and station structures on both underground and elevated metro lines as a way to reduce steel congestion and improve tensile connection.

Moreover, the integrity test of the metro foundations using the Cross Sonic Logging (CSL) testing method was facilitated by the usage of SONITEC sonic tubes, designed for easy assembly and installation in reinforcement cages.

Dextra’s ASTEC soft-eyes are made of GFRP rebar to reinforce D-Walls in underground tunnels, which can easily be cut by Tunnel Boring Machine (TBM), resulting in time and money savings.

The project is still ongoing and the fourth line of the Cairo Metro is expected to start operation in 2020.

那格浦尔地铁,零英里地铁站

那格浦尔地铁,零英里地铁站

那格浦尔地铁零英里站位于马哈拉施特拉邦那格浦尔市的一个混合用途交通/停车/商业项目中。它位于从北到南穿越城市的新地铁线上。零英里站是一个地铁站,由一栋 12 层建筑组成,将设有商业区和可容纳 430 辆车的停车场。

对于该项目,Dextra 于 2017 年参与了地锚的供应和安装,以稳定挖掘区域周围的地面。

Dextra 提供了其创新的 ASTEC (FRP) 主动锚解决方案(AAA),一种特殊类型的地锚,在临时应用的情况下,可以在项目结束后留在地下,即使这些地锚超出了地界线或穿过未来的隧道。

事实上,FRP 锚杆的一个主要优点是使锚杆完全可以通过传统的挖掘设备切割,使其成为传统可移动锚杆的最佳替代品,传统可移动锚杆是最终需要用蛮力从地面移除的钢锚杆。的项目。

Dextra ASTEC 主动锚便于运输,可以由工人搬运到最终位置。一旦插入钻孔,每个锚栓都会被灌浆,然后使用连接到 FRP 锚栓的传统 PT 钢绞线施加应力。安装后,锚固件可以保留在地下,这与传统的可拆卸锚固件不同,传统的可拆卸锚固件需要额外的项目管理并产生报废锚固件拆除成本。
