CHALLENGING PROJECTS


At TUNNELCONSULT ENGINEERING SL we undertake challenges as an opportunity to grow.
Some of our milestone projects can be found herein.

Undercrossing river tunnel floor plan and cross-section

UNDERWATER TUNNELS

Under crossing water bodies (rivers, lakes, canals, harbors & bays) has crucial aspects that shall be carefully assessed.

Drinking water tunnel inspection

HYDRAULIC TUNNELS

Power Project headrace tunnels, drinking water tunnels, irrigation, flood relief or diversion tunnels which are frequently under high inner pressure, need careful consideration of the segmental lining - ground interaction, with demanding structural requirements for long term operation.

Steel fibres for reinforced concrete

FRC SEGMENTAL LINING

Use of fiber reinforcement in precast segments is widespread to improve lining toughness and durability.

Geological profile with faulted anticlinal

HIGH OVERBURDEN TUNNELS

Tunnels with hundred of meters of overburden pose special challenges in understanding rock mass behaviour and interaction with TBM and ring lining support.

Cut&Cover construction site close to dense road traffic avenue

TUNNELS IN URBAN AREAS

Big cities have transport challenges that in most cases have underground solutions. But excavating the city is not an easy journey.

Large diameter TBM cutter-head front view

LARGE DIAMETER AND MULTI-DECK TUNNELS

In dense urban areas high traffic volumes can be tricky.
Large diameter tunnels, even with more than a level, can deal with this problem.

Fresh rock excavation front with curved beams & shotcrete lining

CONVENTIONAL TUNNELLING PROJECTS

Tunnelling-as-usual. Sometimes conventional tunnelling is the better underground solution both from the technical and economic approach.

Large cavern with TBM tunnel and side galleries

LARGE CAVERNS

Wide spaces for stations, tunnel diversion, TBM assembling & disassembling facilities

Micro TBM cutter-head and tail shield

MICRO-TUNNELLING

Also called "pipe-jacking", microtunnelling techniques allow to build a tunnel in an easy way for sewerage, water distribution or other purposes.
