Expanding anchor head, telescopic spiral grouting anchor rod and construction method
The invention discloses an expansion type anchor head, a telescopic spiral grouting anchor rod and a construction method.The grouting anchor rod comprises a hollow anchor rod body, a telescopic rotating rod and the expansion type anchor head, the expansion type anchor head comprises connecting rods, a fixing cap and a fixing bolt, one end of each connecting rod is connected with the fixing cap, the connecting rods are connected through the fixing bolt, and the telescopic rotating rod is connected with the hollow anchor rod body. After the anchor head is stressed, the connecting rod expands outwards, and the anchor head sharp nail on the fixing screw is embedded into a soil body outwards; the hollow anchor rod body comprises an anchor rod body head section, an anchor rod body tail section and a plurality of anchor rod body middle sections, and the anchor rod body sections are connected through threads. The telescopic rotating rod comprises a rotating rod head section, a rotating rod middle section and a rotating rod tail section which are sequentially connected in a sleeved mode. A limiting sliding groove for axial movement of all the sections of the rotating rod is formed in the telescopic rotating rod. The expansion type anchor head disclosed by the invention has relatively strong anchoring force; in addition, the telescopic spiral grouting anchor rod is small in occupied space, convenient to transport and store and simple to operate while enhancing the anchoring and supporting effects.
本发明公开了一种扩张式锚头、可伸缩螺旋注浆锚杆及施工方法，该注浆锚杆包括中空锚杆体、缩旋转杆以及扩张式锚头，其中，扩张式锚头包括连接杆、固定帽以及固定螺栓，连接杆的一端与固定帽连接，连接杆之间通过固定螺栓连接，锚头受力后，连接杆向外扩张，固定螺上的锚头尖钉朝外嵌入土体中；中空锚杆体包括锚杆体首段、锚杆体尾段以及若干个锚杆体中间段，各段锚杆体通过螺纹连接；伸缩旋转杆包括依次套接的旋转杆首段、旋转杆中段以及旋转杆尾段，伸缩旋转杆的内部开设有供旋转杆各段轴向移动的限位滑槽。本发明的扩张式锚头具有较强的锚固力；另外，伸缩式螺旋注浆锚杆，在增强锚固支护作用同时，所占空间小、运输、储存方便、操作简单。
