Project Requirements

Various Elevated Crossbeams

Dimensions of 10′-6″ 3.20 m.(w) x 74′-6″ 22.70 mm(L) x 11′-6″ 3.50 m(H)
Four corbels at the corners of the crossbeam are located 36′ -2″ (11 m) above the existing ground level.

High-Load Capacity

Fully cast concrete at 11′-6″ (3.50 m) height in one pour.

Adjustable Shoring Systems For Concrete Construction

Using different post locations on different ground elevations, each with different ground support bearing capacity.

Formwork Used

Project Overview

The Mass Rapid Transit Authority of Thailand (MRTA) under the Ministry of Transport, the Kingdom of Thailand, is implementing the MRT Yellow Line Project, Lat Phrao – Samrong Section using an elevated monorail system. The total distance of this elevated monorail is long 18.9 miles (30.4-km) with 23 stations, and the total investment cost is 55 billion Thai baht.

Customer Benefits

Inclined Soffit Construction Is Easy With High Load Capacity Shoring System

The E-Z DECK Swivel Head supports the Z-BEAM®, which in turn supports the inclined soffit of the crossbeam. This enabled STECON to easily assemble the E-Z DECK shoring equipment without additional wood blocks or steel fabrication.

Adaptable Shoring System

Once the E-Z DECK Long Jack is attached to the E-Z DECK Post, it easily turns and adjusts the height between 5″ (125 mm) to 965 mm to meet the varying heights of the inclined soffits.

Inclined Parallel To Inclined Soffit

The E-BEAMS were designed to be inclined parallel to the inclined soffit. The benefit of E-BEAMS, which have of holes at 2″ (50 mm) centers, combined with Z-BEAMS, which have holes at 4″ (102 mm) centers, is the contractor can connect the different degree of sloping E-BEAM on the Z-BEAM.

Cast-In-Place Concrete Construction

Most of the typical pier heads in this project are precast, however the long span parts, which is designed to carry the load over the existing obstructions like intersections, bridges, etc., are cast-in-place.
