Root key type stable pressure bearing mechanism in anchor hole, assembling method, root key type anchor cable and method for grouting anchor hole
The invention discloses a root key type stable pressure bearing mechanism in an anchor hole, an assembling method, a root key type anchor cable and a method for grouting the anchor hole. The pressure bearing mechanism comprises a bearing body, root keys and a taper plug, a through hole is formed in the center of the taper plug, threads are machined on the inner wall of the through hole, a taper hole is formed in the center of the bearing body, key holes are formed in the radial direction of the bearing body with the inner wall of the taper hole as the starting point, the number of the key holes is the same as that of the root keys, sliding pairs are formed between the root keys and the key holes, and the outer wall of the taper plug is matched with the taper hole. The sum of the length of the root key and the radius of the corresponding position of the taper plug is larger than the radius of the anchor hole. The length of the root key is smaller than the radius of the anchor hole. When the taper plug is plugged into the taper hole, the head of the root key extends into the rock-soil body of the anchor hole. According to the assembling method, the pressure bearing mechanism can be assembled. The pressure-bearing mechanism assembled by the assembling method is used for the anchor cable, and when the anchor cable is used for grouting, the anchoring effect of the anchor cable can be effectively improved.
本发明公开了一种锚孔内根键式稳固承压机构和组装方法、根键式锚索、向锚孔注浆的方法。该承压机构包括承载体、根键、锥塞，锥塞中心处开设有通孔，通孔内壁加工有螺纹，承载体中心开设有锥孔，以锥孔的内壁为起始点，沿承载体径向设有键孔，键孔的数量与根键的数量相同，根键与键孔之间构成移动副，锥塞的外壁与锥孔相适配，根键的长度与锥塞对应位置处的半径之和＞锚孔的半径，根键长度＜锚孔的半径；当锥塞被塞入至锥孔时，根键的头部伸入到锚孔岩土体中。该组装方法能够组装得到该承压机构。由该组装方法组装得到的承压机构用于锚索，并应用该锚索注浆时，能够有效地提高锚索的锚固效应。
