System of the shotcrete lining reinforced the adhesion/tension by wire mesh and assembly structure thereof and method setting up the wire mesh to the steel rib for tunnel

摘要

The present invention allows the wire mesh to be assembled and installed along the longitudinal direction of the steel support member, but the wire mesh is located below the neutral axis by the bending vertical portion, so that the wire mesh itself serves as an intermediate attachment support member for the upper and lower attachment spaces of the wire mesh The performance of the shotcrete is increased or improved at the time of pouring due to its role as an intermediate support material, so that the casting thickness of the shotcrete layer is increased by 1.2 to 2.0 times the conventional thickness (80 mm) The tensile performance of the shotcrete against the pressure is improved and reinforced to provide a structurally stable shotcrete support. On the other hand, since the thickness of the shotcrete once cast is increased compared to the prior art, the number of times of casting is reduced, The instability is reduced so much that the structural stability of shotcrete reinforced concrete is further strengthened and improved. The invention.
