Longitudinal and transverse bidirectional energy dissipation and seismic mitigation fabricated anchor rod and construction method thereof
The invention discloses a longitudinal and transverse two-way energy dissipation and shock absorption fabricated anchor rod and a construction method thereof. The fabricated anchor rod comprises an anchor head rod piece, a longitudinal and transverse two-way energy dissipation and shock absorption device and a straight screw rod which are connected with one another. The longitudinal and transverse bidirectional energy dissipation and shock absorption device comprises an external threaded rod piece and an internal threaded rod piece, the external threaded rod piece and the internal threaded rod piece are each provided with a movable groove, a limiting circular ring, a friction plate, a cylindrical block, a spring, a shear steel body and a hoop, and the movable grooves and the limiting circular rings are integrally formed. Tangential energy generated by an earthquake is dissipated through reciprocating tangential plastic displacement of a shear yield damping structure formed by welding a shear steel body and a cylindrical block. The anchor rod can be prevented from being stretched and sheared when an earthquake occurs, and the anti-seismic property of the side slope is improved.
本发明公开了一种纵横双向耗能减震的装配式锚杆及其施工方法，包括相互连接的锚头杆件、纵横双向耗能减震装置和直螺杆。纵横双向耗能减震装置包括外螺纹杆件和内螺纹杆件，外螺纹杆件和内螺纹杆件各设置有一体成型的活动凹槽和限位圆环、摩擦板、圆柱块、弹簧、剪切钢体和套箍，圆柱块的轴向伸缩移动可吸收消耗地震产生的轴向能量，通过剪切钢体与圆柱块焊接形成的剪切屈服阻尼结构的往复切向塑性位移耗散地震产生的切向能量。本发明能在发生地震时防止锚杆发生拉伸、剪切破坏，提高边坡抗震性能。
