Shotcrete support . 3. Wet mix shotcrete . In this case the shotcrete components and the water are mixed (usually in a truck mounted mixer) before delivery into a positive displacement pumping unit, which then delivers the mix hydraulically to the nozzle where air is added to project the material onto the rock …

Today, both wet- and dry-mix systems of shotcrete emplacement have applications in rock support. Introduced in 1955, wet mix has the advantages of being able to achieve better material consistency through off-site mixing, producing less dust, and achieving greater volumes in a given time.

Ground Support & Underground. Earth and rock excavations are effectively stabilized with shotcrete and a variety of reinforcement and anchoring systems. Using shotcrete to stabilize soil for excavation has advantages over traditional timber and steel shoring techniques. Shotcrete is also ideal for ground support in tunneling and mining.

Shotcrete support When shotcrete is applied to rock masses with well-defined water-bearing joints, it is important to provide drainage through the shotcrete layer in order to relieve high water pressures. Drain holes, fitted with plastic pipes as illustrated in Figure 12, are commonly used for this purpose.

One of the many applications of shotcrete in civil engineering work is that of slope support, a cut in the terrain which is at a steep angle to the horizontal.. Slopes, which are often created during the construction of highways, dams or railway lines, are generally designed so that the rock mass can support itself; but they may sometimes require additional support to avoid slipping and failure.

strength of the rock mass so that it becomes self-supporting. Rock support generally combines the effects of reinforcement, by such elements as dowels, tensioned rock bolts and cables, and support, with shotcrete, mesh and steel sets which carry loads from individual rock blocks isolated by structural discontinuities or zones of loosened rock.
