Pressure dispersion type anchor cable for slope treatment
The invention discloses a pressure dispersion type anchor cable for slope treatment. The pressure dispersion type anchor cable is characterized in that a limiting plate, an extrusion sleeve, spiral ribs and a bearing plate form a combined body to effectively relieve large local pressure of an anchor cable steel bar, so that the service life of the anchor cable steel bar and the actual slope supporting effect are guaranteed. After the spiral ribs are solidified into a whole through grouting of a grouting pipe, stress on the bearing plate can be effectively relieved, the service life of the bearing plate is guaranteed, the service life of the whole anchor cable is guaranteed, and concrete behind the rear side face of the bearing plate is prevented from being crushed. On the front side face of the bearing plate, the limiting plate is connected to the front side face of the bearing plate through a pull rod, a stable consolidation body is formed on the front side face of the bearing plate after grouting, the bearing capacity of the anchor cable is improved, the extrusion sleeve is formed at the head end of a prestressed tendon in an extrusion manner, and the service life of the prestressed tendon is guaranteed. According to the pressure dispersion type anchor cable, the problem that concrete behind a bearing plate in an existing pressure dispersion type anchor cable is prone to being crushed is solved.
本发明公开了一种用于边坡治理的压力分散型锚索，通过限位板、挤压套、螺旋筋条以及承载板组成一组合体以有效缓解锚索钢筋的局部压力大，保证了锚索钢筋的使用寿命和实际的边坡的支护效果。螺旋筋条通过注浆管注浆固化呈一体后，可有效缓解承载板上的应力，保证了承载板的使用寿命，保证了整个锚索的使用寿命，避免承载板的后侧面后方的混凝土被压碎。在承载板的前侧面，限位板通过拉杆连接于承载板的前侧面，在注浆后以于承载板的前侧面形成稳定的一固结体，提高锚索的承载力，挤压套挤压成形于预应力筋的头端，保证了预应力筋的使用寿命。本发明解决了现有的压力分散型锚索存在锚索中的承载板后方的混凝土容易被压碎的问题。
