However, the inhaul cable 8 provides good limiting capacity, and vertical additional pressure is generated due to a large included angle formed between the inhaul cable 8 and the horizontal direction, so that vertical bearing of the support is not facilitated; when the stay 8 performs the limit function, the horizontal rigidity of the stay is suddenly increased to generate a certain degree of impact. In order to eliminate the adverse effect, the stay cable 8 is not directly connected with the lower seat plate 2 in the application, two ends of the stay cable 8 are connected with the mild steel buffering energy dissipation component 11, and the buffering energy dissipation component 11 is connected with the lower seat plate 2 through the base.
Furthermore, through setting up buffering type anchor, raised the power transmission point of cable, through setting up guide block 16, make cable 8 tension moment, produced vertical component when having avoided the cable spacing. Meanwhile, the impact effect can be reduced through the elastic-plastic deformation of the mild steel buffering energy dissipation component, and the energy dissipation capacity of the support is improved; the displacement limiting capability of the support is weaker due to the low strength and the large plastic deformation capability of the mild steel; in order to guarantee the good spacing ability of support, this application is through buffering type anchor's base and spacing restraint apron, with the control of the elastoplasticity deformation of mild steel buffering power consumption component within a reasonable scope, guarantees that the displacement of support is controllable.
