Bangkok’s MRT Orange Line is one of the planned rapid transit lines of the Mass Rapid Transit Authority of Thailand (MRTA). The main purpose of this 39.5-kilometer railway line is to improve the connection between western, central and eastern parts of Bangkok, and consequently ease the Thai capital’s traffic congestion. This project is also part of Thailand’s plan to stimulate the national economy and improve the infrastructure.
La Línea Naranja del MRT está dividida en dos secciones: desde Bang Khun Non hasta el Centro Cultural de Tailandia, y desde el Centro Cultural de Tailandia hasta Min Buri, y comprende 22 estaciones subterráneas y 7 estaciones elevadas.

dextra Ojos suaves de GFRP for tunnel construction

Para el tramo Centro Cultural de Tailandia - Min Buri, el contratista Joint-Venture of Italian-Thai Development y CKST optaron por más de 40 unidades de la solución llave en mano de Dextra para la construcción de túneles FRP Soft-Eye.
Being well-known for its unique cut-ability technology, Glass Fiber Reinforced Polymer (GFRP) Soft-eyes facilitates break-ins and break-outs of the Tunnel Boring Machine (TBM). This is in fact the best alternative to conventional steel reinforcement – which would require mobilization of additional manpower and equipment.

dextra Sonitec for Crosshole Sonic Logging (CSL) tests

In order to verify the integrity of concrete in deep foundations, Italian-Thai Development, CKST JV and Unique Engineering have also chosen Dextra’s cross-hole sonic logging tubes – Sonitec. These CSL tubes are available in several diameters, and have been specifically designed for easy and fast handling to accelerate construction speed. Over 30,000 tubes have been delivered to the project as of March 2022.

To optimize the reinforcement of the Diaphragm Walls (D-Walls), bartec, one of Dextra’s mechanical rebar splicing systems, was installed. Thanks to its easy-to-install characteristic, bartec helps accelerate the projects schedule and reduce inventory as the standard coupler can also be used for Position splices. More than a million of bartec couplers have been delivered to the site.

Moreover, around 7,000 headed bars were applied at the end of the reinforcement bar as an alternative to hooks in congested areas of the structure.
