Construction Of A Reinforced Soil Wall For A Working Platform For A 1000 Ton Crane And A TBM Machine

Project Overview

This is a rehabilitation project where sections of a 100 year old structure, Elan Valley Aqueduct (EVA) needed to be replaced. The EVA is an extremely crucial resource as it supplies water to Birmingham and its adjacent areas. The aqueduct is approximately 120 km long, discharges 300 million liters of water every day into the reservoir at Frankley Water Treatment Works (WTW) in Birmingham, and currently supplies water to about 1.2 million people. There was a need to refurbish and modernize the aqueduct so that it can be preserved for the future. For this, a new conduit with a tunnel of 1.8 km long and 3.0 m diameter was proposed to be constructed. For the construction of the bypass conduit, a horizontal working platform of 160m long and maximum 14.0 m high was required to support the construction traffic, the 1000 ton crane used to assemble the Tunnel Boring Machine (TBM) and the 150 ton TBM.
