カイロ モノレールは、エジプトのカイロにある 2 線のモノレール高速輸送システムで、現在建設中です。プロジェクトが完了すると、この 2 つの路線により、新行政首都および 10 月 6 日市からカイロ都市圏までの初の公共交通機関が提供されることになります。

新行政都市と東カイロ間の54キロは60分、10月6日市とギザ間の42キロは42分かかる。

デクストラ supplied more than 300,000 バーテック standard and bridging couplers for the connection of reinforcement bars. バーテック is simple to install and does not require professional skilled labor, which reduces labor on the job site, formwork costs, and increases job site safety.

Around 400,000 バーテック headed bars were also installed as a replacement for フックバー in concrete members and connections.

Moreover, the project used ユニテック bolted couplers in repair works for the connection of two rebars which have not or cannot be threaded.

このシステムの第 1 段階は 2022 年に一般公開され、続いて 2023 年に第 2 段階が公開されます。

The Forrestfield Airport Link is a rail infrastructure project lolcated in Perth, Western Australia. The 8.5km line will connect the existing Midland Line to Perth International Airport and further to the eastern suburbs. The project features two twin-tunnels bored with Tunnel Boring Machines (TBMs) which move up to 26 meter underneath the bed of Swan river, highways and Perth Airport, adding three new stations to the city’s transportation network: Belmont, Airport Central and Forrestfield.

For the tunnel boring packages, デクストラ supplied a total of 10 GFRP ソフトアイズ between 2016 and 2017 (two for Airport Central Station, two in Abernethy, four in Belmont and two in Bayswater) to the contractor JV of Salini Impregilo and NRW Salini Impregilo. ソフトアイズ are rebar cages made mostly of Glass-Fiber Reinforced Polymer (GRFP) bars and some steel rebar. ソフトアイズ can be cut by the TBMs and allow faster equipment breakthrough, saving precious time while avoiding to damage the TBM heads.

デクストラ also supplied a total of 65,000 グリップテック connections for the station works. グリップテック is distributed in Western Australia by Dextra’s partner InfraBuild Construction Services. They offer the complete service to the contractor: Cutting the rebar, preparing the bar ends with グリップテック sleeves and bending them for final installation on site. This allows the contractor to achieve faster cycle times in rebar connection on site .

ソニテック, Dextra’s steel tubes for Crosshole Sonic Logging tests (to check concrete integrity in bored piles) were also supplied.

The Forrestfield-Airport Link will operate in 2022.

ブリュッセル メトロは、ベルギーの首都ブリュッセルの大部分を運行する高速交通システムです。従来の地下鉄 4 路線と地下鉄以前の 3 路線で構成されています。

Line 3 is a tram line that runs through the city center from Churchill in the south to Esplanade in the north, using the North-South Axis tunnel. The total route will be 10.3km long.

An 150m long new tunnel was dug underneath the Brussels North railway station to connect two existing underground tunnels. It was an important component of the new metro link.

Dextra supplied ソニテック, a tube solution that facilitates the integrity testing of foundations using the CSL testing method, to the construction site of Line 3. 13 kilometers of the tubes were installed in the 18m long pile cages.

の ソニテック system has been designed with the sole purpose of being easy to assemble and install in reinforcement cages.

The Cairo Metro is a rapid transit system in Greater Cairo, Egypt. It was the first of three fully-fledged metro systems built in Africa, as well as the first in the Arab world. It began service in 1987 as Line 1 between Helwan and Ramsis Square, covering a distance of 29 kilometers.

The Cairo Metro currently has 74 stations, 3 of which are transfer stations, with a total length of 89.4 kilometers as of August 2020. There are three operating lines in the system.

The new line, line 4, will run from Makram Ebeid Station to Police Academy Station near the Ring Road, with bored tunnels following Doctor Hassan El-Sherif Street and Ahmed El-Zomor Street. It will be 24 kilometers in total length.

Construction began in Q3 2019 and is expected to be completed in 2024.

Dextra has supplied 450,000 Bartec+ couplers and 42 GFRP soft-eyes for the reinforcement of the 地中隔壁.

Bartec+ is a mechanical splicing system with parallel threads for connecting concrete reinforcement bars with diameters ranging from 12 to 50 mm (ASTM #4 to #18). The threaded rebars are tensile tested at 90% of the rebar yield strength.

Dextra’s GFRP soft-eyes solution is an integrated turn-key solution that uses cut-able Glass Fiber Reinforced Polymer (GFRP) reinforcement as an alternative to traditional steel rebars, allowing the penetration of Tunnel Boring Machines (TBM) to pass through 地中隔壁 with ease.

The Lucknow Metro project is built to serve the growing population of Uttar Pradesh, North India, as well as to serve the areas that are not connected by the existing rail system. The 35km rail system comprises 22 stations, of which 19 will be elevated.

The first phase of the project consists construction of 2 rail lines (North- South and East-West corridor), connecting the four corners of Lucknow by running through the heart of the city. Being implemented by Lucknow Metro Rail Corporation (LMRC), the Phase 1 comprises the construction of 22.8km long North-South corridor.

The priority section is the 8.5 kilometers linking Transport Nagar to Charbagh.
ラクナウ地下鉄が運行されれば、市内の交通が緩和され、通勤者の移動時間も短縮されます。

The 37km-long Light Rail Transit Line 3 (LRT3) is a light rail line under development in Malaysia. It includes a 35km viaduct and a 2km underground tunnel which will link Bandar Utama with Johan Setia in Klang.

クアラルンプール/クランバレー都市圏 (GKL/KV) の陸上公共交通マスタープランに沿って開発された LRT3 は、GKL/KV の西回廊への鉄道接続を拡張する上で戦略的な役割を果たします。

Dextra provided cuttable Glass Fiber Reinforced Polymer (GFRP) soft-eye solutions, installed in diaphragm walls of escape shafts, in order to facilitate the underground tunnel breakthrough by the Tunnel Boring Machines (TBM).

LRT3 プロジェクトは、クランからペタリン ジャヤまでのクラン バレーの西回廊沿いの接続性を改善し、交通渋滞を緩和し、経済成長を促進することにより、線形全域で 200 万人の人々にサービスを提供すると期待されています。

工事完了は2024年2月の予定。

パナマ地下鉄 3 号線は、パナマ地下鉄プロジェクトの一環として開発されている全長 34 km のモノレール路線です。これはパナマ運河の拡張以来、同国最大のプロジェクトとなる。

この路線により、パナマ オエステ県とパナマ県が結ばれ、平均所要時間は 90 分から 45 分へと半分に短縮されます。このモノレールシステムは、アメリカ大陸で初めて日本の技術を導入したものとなる。

Dextra supplied 260,000 バーテック couplers for the elevated monorail structure’s piling column and precast beam connection.

ソニテック tubes were also used to examine the concrete integrity of bore-piles using the crosshole sonic logging testing method.

この路線は2025年半ばに運行開始が予定されており、パナマ・オエステ県の50万人以上の住民に恩恵をもたらすことになる。

リマ地下鉄はペルーの高速交通システムで、現在リマ南部のビジャ エル サルバドル地区と市北東部のサン ファン デ ルリガンチョを結んでいます。地下鉄 1 号線は 2011 年に開業し、26 駅、全長 34.6 キロメートルで、アメリカ大陸最長の地下鉄路線です。

デクストラ is proud to contribute to the construction of Metro Line 2 and the initial phase of Line 4, both of which commenced simultaneously in 2016. Line 2, a 27-kilometer fully underground transit route, will seamlessly connect Lima’s Ate district with the Callao region. Meanwhile, the first 8-kilometer segment of Line 4 will serve as a crucial link between Line 2 and the Jorge Chávez International Airport station, enhancing connectivity for commuters and travelers alike.

More than 160,000 ロールテック rebar couplers have been supplied to the Metro construction site to avoid rebar congestion of the traditional overlapping method.

Several types of ロールテック couplers were installed in various parts of the stations’ structures, including standard couplers size #8, #11 and #14, and transition couplers size #8 and #11.

全線は2024年に稼働する予定だ。

The Sha Tin Sewage Treatment Works Relocation project was aimed to relocate the Sha Tin Sewage Treatment Works (STW) in Sha Tin, Hong Kong, which is currently located at the mouth of the Shing Mun River, to the cavern site at Nui Po Shan of A Kung Kok on the opposite bank, freeing up the existing site for uses beneficial to people’s livelihood and improving the local living environment.

The future Sha Tin Cavern STW will be the largest of its kind in Hong Kong, occupying 14 hectares of land. It will have the same treatment capacity as the current site, but will use advanced sewage treatment technology to meet local population demands and improve services for residents.

For the tunneling works, Dextra has supplied around 800 pieces of GEOTEC™ GFRP rock-bolts for the tunnel’s temporary supporting.

GEOTEC™ GFRP rock-bolts are made of cut-able glass fiber reinforced polymers, making them perfect for face bolting or any other tunneling and mining application where further excavation is required.
