TUNNEL SPRAY ANCHOR SUPPORT

Shotcrete-bolt support refers to the combined action of high-pressure sprayed cement concrete and metal bolts driven into the rock formation (it can also be used separately according to the geological conditions) to strengthen the rock formation, and is divided into temporary support structures And permanent support structure. Shotcrete can be used as the initial support for the surrounding rock of the cavern or as a permanent support. Shotcrete anchor support is a system that makes the bolt, concrete shotcrete and surrounding rock form a joint action system to prevent loosening and separation of the rock mass. The surrounding rock of a certain thickness is transformed into a self-supporting arch, which effectively stabilizes the surrounding rock. When the rock mass is relatively broken, the wire mesh can also be used to block the small rock blocks between the anchor rods to enhance the concrete spray layer and assist the spray anchor support.
