With efficient belt conveyors the transport of theexcavated material keeps pace with thetunnelling progress.

Belt conveyor systemsTop performance for the removal ofexcavated material

________________ Several hundred meters ofnewly excavated tunnel a week are notuncommon in mechanized tunnelling, dependingon the geology. The belt conveyors for removingthe excavated soil or rock must keep pace. Areliable belt conveyor system as a seamlessinterface between the tunnel boring machine andthe jobsite aboveground is thus an essentialfactor. With its many years of experience and inclose cooperation with the customer, theHerrenknecht subsidiary H + E Logistik GmbH manufactures powerful belt conveyor systemsthat are exactly tailored to the needs of the tunnelling process.

Fast, far and flexibleThe transport of excavated material on beltconveyor systems is the most direct and often themost cost-efficient way. With high advance ratesand excavation diameters of 8 to 9 meters, thedaily amount of rock or soil excavated can exceed10,000 cubic meters. Another challenge is theconveying distance that becomes longer, thefurther tunnelling progresses, and individualdistances of up to 15 kilometers are possible. Toextend the belt during operation, horizontal orvertical belt conveyor storage systems are used,depending on the space available on the jobsite. Ifthe tunnel portal is located below the jobsite

ADVANTAGES

Belt conveyor, belt storage and stackingsystems. Comprehensive logistics solutions fromH + E for a tunnel jobsite in Sochi, Russia.

surface, for example in a shaft, vertical belt conveyors or ascending belts transport theexcavated material to the surface. So-called stacking systems are located here and these areprecisely adapted to the jobsite conditions for the optimal stacking of the excavated material.

+ Seamless interface to the TBM

+ Removal of the excavated material adjusted to the tunnelling speed

+ Low personnel requirements through automated processes

+ Extreme track routes possible: around curves, corners, on gradients of up to 15 degrees and vertically

Safety firstEfficient belt conveyor systems are high-tech systems. They keep personnel costs and the riskof accidents to a minimum at extremely high conveying capacities. The belts convey enormousamounts of excavated material to its destination point with great precision. Safety is alsoensured even when driving along curves with a tight radius. For this purpose, additional drivesare installed before the individual curves. These tunnel boosters reduce the forces that act onthe belt. In this way, the excavated material can be transported safely around even the tightestcurves. For long straight routes, the boosters provide extra thrust and have a positive impacton the efficiency of the belt conveyor systems.

Keeping pace with tunnellingWith an efficient back-up logistics system, tunnelboring machines can reach their full potential.Depending on the jobsite requirements andconditions, high-tech tunnel belt conveyorsystems from H + E Logistik, which are specificallytailored to the respective conveying volumes,ensure the smooth removal of the excavatedmaterial. They are closely aligned to therequirements of the tunnel boring machine andthus vital for the success of a project.
