Tunnel and shaft

Segmental shaft linings provide a safe and efficient method for construction of permanent and temporary shafts for sewer, ventilation and tunneling launch and retrieval shafts. Standard segment designs are suited to shaft depths of up to 30 metres.

Humes also offer a range of standard one piece caisson units suitable for fast and simple construction of small diameter shafts.

Humes has developed a large range of custom designed arches that are ideal for a variety of complex heavy loading criteria and internal envelops.

Large diameter steel reinforced concrete pipes are an ideal solution for escape tunnels where heavy loads will be imposed.

Humes manufacture extra large spaned box culverts for safe access to mine and construction sites and as conveyer tunnels.
