“Box Jacking in Urban Areas”
Don Hall – MD CREG Asia & Africa

In today’s environment of increasing traffic congestion in cities clients are looking to reduce the impact on the surface during construction works for underpasses for traffic and MRT stations. ZURPB (Zhengzhou Urban and Rural Planning Bureau) decided to construct 3 quadruple tunnels to underpass the main North-South arterial highway. According to the plan, each completed quadruple-tunnel consist of twin 8 x 4.5 metres tunnels for vehicles and twin 6 x 2.8 metres for non-motorized vehicle.

Work scope of Lot 1 which includes Hongzhuang Road tunnel consists of 105 metres bored tunnel section as well as a 545 metres cut and cover section. The over burden is 8 metres with the tunnel excavation dimensions of 10.1 metres wide and 7.45 metres high. Lot 2 includes Weisi Road tunnel and Shenzhuangbeilu – Shangding Road tunnel. Weisi Road tunnel consists of 100 metres bored tunnel section and 150 metres cut and cover section. Shenzhuangbeilu – Shangding Raod tunnel consists of 190 metres bored tunnel section and 605 metres cut and cover section. CREG have manufactured the world largest EPB Box jacking machine to complete this Project.

LTA in Singapore have taken the bold step of introducing large cross section box-jacking for pedestrian underpasses on the Thomson Line. CREG will be supplying a Box-Jacking EPB TBM for use in Singapore. This presentation will show case a study of the Zhengzhou Project as well as the planned works for the Box-jacking section on the Thomson Line, Singapore.
