Method for reinforcing broken slope body
The invention discloses a method for reinforcing a broken slope body. The method comprises the steps that S1, a hole channel with a preset depth is drilled on a slope body from a high position to a low position in an inclination direction of the slope body, and the hole channel is vertical to a slip crack surface of the slope body; S2, an anchor cable body and a grouting pipe extend into the hole channel to a necessary depth through an inlet of the hole channel; S3, the grouting pipe begins to grout and is slowly pulled at a constant and slow speed until the hole channel is completely grouted and the grouting pipe is separated from the hole channel; S4, slurry in the hole channel is waited to be solidified to form a core body, and an anchorage pier is built at the inlet of the hole channel at the same time; and S5, the anchor cable body is tensioned in a post-tensioned prestressing mode. According to the method for reinforcing the broken slope body, the bonded section of the anchor cable body is at the far end of an anchor cable, the inversion of anchoring stress is achieved, through the arrangement of the bonded section, the anchoring stress of the core body is guaranteed to be transmitted and the reliability is guaranteed, and an inverted stress method technology is achieved. A non-bonded section is arranged, the anchor cable does not bond and anchor with the core body is guaranteed, and meanwhile the achievement of an inverted stress method is guaranteed. A theoretical zero anchoring stress section ensures that the inverted stress method technology is safe, reliable, economical and reasonable.
本发明公开了一种破碎滑坡体的加固方法，S1、沿坡体倾斜方向且由高处向低处在坡体上钻取垂直坡体滑裂面的预设深度的孔道；S2、将锚索体、灌浆管通过孔道的入口伸入到孔道中的必须深度；S3、灌浆管开始灌浆并缓慢匀速的拉取灌浆管，直至孔道完全灌浆，灌浆管从孔道中脱离；S4、等待孔道内的浆体凝固形成芯体并同时在孔道入口处建立锚墩；S5、通过后张法预应力的方式张拉锚索体。本方法的锚固应力通过锚索体的有粘结段在锚索远端，实现锚固应力倒置，通过设置有粘结段，保障芯体锚固应力传递并可靠，实现倒置应力法技术。设置无粘结段，保障锚索不与芯体产生握裹锚固，同时保障倒置应力法实现。理论零锚固应力段，保障倒置应力法技术安全可靠、技术经济合理。
