Self-expansion bag type expansion anchor rod supporting structure and construction method
The self-expansion bag type expansion anchor rod supporting structure comprises an anchor rod body, the bottom of the anchor rod body is sleeved with a fixing cylinder, the outer wall of the fixing cylinder is sleeved with a bag, the top of the fixing cylinder is provided with a grouting device, and the top of the fixing cylinder is in threaded connection with the anchor rod body through an upper fixing device; a limiting device is arranged at the top of the anchor rod, a protection head is connected to the bottom of the anchor rod through threads, an extending cylinder is in sliding contact with the interior of the limiting hole, a plurality of grouting holes are formed in the middle of the outer wall of the extending cylinder in the circumferential direction at equal intervals, and a clamping ring is fixedly connected to one end of the extending cylinder; the other end of the extension cylinder is fixedly connected with a limiting ring which is matched with the annular groove. The extension cylinder can be inserted into slurry in the bag after extending outwards, after the slurry is solidified, the contact area between the extension cylinder and the slurry is increased, the connection strength of the anchor rod body and the slurry in the bag is improved, stability is improved, and the anchoring effect is further enhanced.
本发明公开自膨胀囊式扩体锚杆支护结构及施工方法，包括锚杆本体，锚杆本体底部套设有固定筒，固定筒外壁上套设有囊袋，固定筒的顶部设置有灌浆装置，固定筒的顶部通过上固定装置与锚杆本体通过螺纹连接，锚杆的顶部设置有限位装置，锚杆的底部通过螺纹连接有防护头，限位孔内滑动接触有延伸筒，延伸筒的外壁中部周向等间距开设有若干灌浆孔，延伸筒的一端固接有卡接环，限位孔外部孔口处外壁上开设有环形槽，延伸筒的另一端固接有限位环，限位环与环形槽相适配。本发明可实现延伸筒向外延伸后，插入到囊袋内的浆料内，待浆料凝固后，增加了与浆料的接触面积，提高了锚杆本体与囊袋内浆料的连接强度，提高了稳定性，进一步增强锚固效果。
