AugerPro System – Pipe Jacking
Tunnel length: Diameter: Geology: | Up to 300m OD200 – OD1600 soft ground (sand, silts, clay), without any boulders |
Features: | Low groundwater levelExcavated soil is transported by auger train to the start shaftPush pipes directly after drilling |
Slurry Systems – Pipe Jacking
Tunnel length: Diameter: Geology: | 1.000m and more OD350 – OD4000 All conditions |
Features: | Difficult soil with high levels of ground waterFor very long distances and large diametersExcavated spoil is mixed with water, transportation to the surfaceWater and spoil get seperated, water maintains in the slurry circleFour different modes, usability for different geologiesAdditives or betonite are not required |
mts Hybrid: | Slurry systems – suitable for pipe jacking and segmental lining projects If there is no possibility for building a rescue shaft > switch to segmental mode > finish tunnelling |
EPB Systems – Pipe Jacking
Tunnel length: Diameter: Geology: | 1.000m and more OD1200 – OD4000 Soft ground |
Features: | Fine soils with low water permeabilityFor very long distancesExcavated soil gathers in the excavation chamberSoil and advancing force build the support pressureExcavated soil transported by screw conveyor out of the excavation chamberBy conveyor belts or lorries to the launching shaft |
mts Hybrid: | EPB systems – suitable for pipe jacking and segmental lining projects If there is no possibility for building a rescue shaft > switch to segmental mode > finish tunnelling |
Hard Rock Systems – Pipe Jacking
Tunnel length: Diamater: Geology: | 1.000 m and more DN 1200 – DN 4000 fractured and unfractured Rock |
Features: | With a gripper station in stable ground conditionsGrip against the tunnel wall to move forwardIn fractured rock > unstable tunnel walls supported by pipes or segments > Segmental Lining |
System 2 – Smart Combination of HDD Drilling and Microtunneling
Push Force: Diameter: Geology: | 400t up to 1.000t OD500 – OD1500 All conditions |
Features: | Usability for pre-bent and straight pipesVariable feeding length of 6 m up to 24 mTime-saving and cost-saving shaft installationStart angle: 0-25° and more, min. curve radius: 150mStrong cooperation |
Our microtunneling systems are easy to handle with our mts power pack container. Our laser guidance systems ensure high accuracies. You will obtain an overview of the main components at the following link: Components
