Anchoring device for unfavorable geological section and construction method thereof
The invention discloses an anchoring device for an unfavorable geological section and a construction method of the anchoring device, which can enlarge the opening angle of an anchor petal of an expansion shell type anchor rod, solve the problem that the inner anchor end of the anchor rod is difficult to lock, improve the success rate of anchoring, shorten the construction time consumption of the anchor rod under the unfavorable geological condition and ensure the safety in the construction process. Comprising an anchoring section, a dowel bar assembly and a tension rod assembly which are rotationally connected in sequence; the anchoring section comprises an anchor clack, an opener and a limiting piece, the limiting piece is arranged at the top end of the anchor clack, the dowel bar assembly is formed by sequentially connecting a plurality of hollow anchor rods in a sleeved mode, the opener is arranged on the section, close to the anchor clack, of each hollow anchor rod, the section, away from the anchor clack, of each hollow anchor rod is an exposed section, and the exposed sections are connected with the tensioning rod assembly. The exposed section is sleeved with a hemispherical nut and a base plate, a grouting hole is formed in the base plate, and a grouting pipe is arranged in the grouting hole.
本发明公开了一种用于不良地质段的锚固装置及其施工方法，能够扩大涨壳式锚杆锚瓣的张开角度，解决锚杆内锚端锁定困难的难题，提高锚固的成功率，同时缩短了不良地质条件下锚杆施工耗时，保证施工过程中的安全性。包括依次转动连接的锚固段、传力杆组件以及张拉杆组件；所述锚固段包括锚瓣、张开器和限位片，所述限位片设置在锚瓣的顶端，所述传力杆组件由多根中空锚杆依次套接形成，所述张开器设置在中空锚杆靠近锚瓣的一段，所述中空锚杆远离锚瓣的一段为外露段，所述外露段与张拉杆组件连接，外露段上套设有半球形螺母和垫板，所述垫板上开设有灌浆孔，灌浆孔内置有灌浆管。
