TUNNELLING
Tunnel boring equipment and auxiliary products for TBM tunnelling
TUNNEL BORING EQUIPMENT
Tunnel boring equipment requires efficient, safe and cost-effective tools and products to ensure optimal excavation and high quality results. AB Tunnelling offers a full range of solutions designed to optimize drilling processes, improve operational efficiency and reduce costs and downtime.
RingX ®: the TBM cutters
We develop and produce RingX ® a new generation of TBM disc cutters (“cutting rings”) with very high performance that improves TBM production and efficiency.
RingX ® are developed to maximize penetration rates and ensure longer service life. Thanks to their wear resistance, they help reduce maintenance costs and increase productivity.
The technical characteristics of our cutting rings guarantee a strong reduction of TBM downtime and consequently a lower number of interventions to the excavation front.
The features of our RingX ® make it extremely performing and cutting-edge in the field of tunnel boring equipment and TBM cutting tools.
BrushX: the tail brushes
We have designed and manufactured a tail skin brush with an innovative design.
Our BrushX, mounted on the TBM shield, ensures optimal distribution and effective sealing of the backfilling mixture, maximizing excavation efficiency.
Our tail brushes play an essential role in maintaining an effective seal, limiting material loss and ensuring greater stability during tunnelling.
They are fundamental in the context of tunnel boring equipment.
Auxiliary products for tbm tunnelling
In addition to cutting tools and tail brushes, our range of tunnel boring equipment includes ground conditioning agents that are essential for optimizing the properties of the soil during excavation. We supply high quality polymers, foams and additives designed to improve soil consistency, control water flow and reduce cutter wear. These solutions allow TBMs (Tunnel Boring Machines) to operate with maximum efficiency in different geological conditions, guaranteeing safe and sustainable excavations with a minimum environmental impact.
Chemical consumables
A wide range of polymers and ground conditioning agents. Readily biodegradable foaming agents for ground conditioning for EPB TBMs and dedusting and rock drilling improvement.
TBM main bearing grease and tail skin grease.
Mono-and two-components foams and resins, expanding or rigid.
We offer a range of more than 15 resins with various chemical compositions, including structural, rigid, semi-rigid, and expanding types, which are used to stabilize and consolidate fault zones at the excavation face or behind prefabricated segments.
Grout and bentonite
To ensure stability and longevity of tunnel structures, AB Tunnelling provides advanced solutions for customized backfilling mixture, designed to fit the specific needs of each project. Our customized backfilling mixture provide optimal filling of the annular space, strengthening tunnel liners and improving their resistance over time. These advanced formulations reduce the risk of surface subsidence, increasing the safety of excavation and the structural integrity of the tunnel.
– Design of backfilling mixture formulation (bentonite-retardant-silicate basis) for mechanized excavation applications to suit project requirements.
– Ground conditioning for Slurry TBMs and cake formation ahead of excavation front inspection.
