Self drilling rock bolt of Metis is a useful
Metis’s components create an in-situ reinforcement system for the stabilization of excavations and slopes during
top-down construction.
Oversized holes of 100mm to 200mm in diameter are drilled and the centralized self drilling rock bolt component is placed. The drill hole is
then tremie grouted with cement grout. After the drill hole grout is cured, the soil nails may be torque tensioned against the protective
shotcrete face to a slight load if desired.
Self drilling rock bolt consists of the passive reinforcement (i.e., no post-tensioning) of existing ground by installing closely spaced
steel bars (i.e., nails), which are subsequently encased in grout. As construction proceeds from the top to the bottom, shotcrete or concrete
is also applied on the excavation face to provide continuity. Self drilling rock bolt is typically used to stabilize existing slopes or
excavations where top-to-bottom construction is advanatageous compared to other retaining wall systems. For certain conditions, self drilling
rock bolt offers a viable alternative from the viewpoint of technical feasibility, construction costs, and construction duration when
compared to ground anchor walls, which is another popular top down retaining system.
Metis stands ready to support you during the design, planning and construction of your project.Sinorock has worked over last decade on the
development of self drilling rock bolt systems. Today,Metis work in this field with an outstanding reputation of product quality and customer
