The tubular Pipe Umbrella system is capable of increasing stability and safety in the work area, stabilizing not only the region of the cap, but also reflecting on the frontal stability, thereby mitigating the deformations in the rock mass induced by the excavation.
It is an easy-to-implement system, which is one of the main advantages, due to the type and cost of the equipment used in the installation (Drilling Jumbo) and the low specialization of the workers, adapting perfectly to variations in geological conditions.
