Auxiliary device for ultra-long anchoring cable deep hole bottom mounting and mounting method of auxiliary device
The invention discloses an auxiliary device for ultra-long anchoring cable deep hole bottom mounting. The auxiliary device comprises an anchoring end and a traction end, wherein the anchoring end is an inverted-circular-truncated-cone-shaped anchoring rod, the traction end comprises a pulley, the pulley is rotationally connected with a pulley fixing base through a pulley rotating shaft, and the pulley fixing base is fixedly connected to the top of the anchoring end; and one end connected with the anchoring end, of the pulley fixing base is cylindrical, and an external thread cooperating with an internal thread in the inner wall of the end of a hollow drill rod is formed in the surface. The mounting method comprises the steps that two drill rods with different hole diameters are adopted fordrilling, and an anchoring cable hole with a large hole diameter and an anchoring hole with a small hole diameter are formed; a static crushing agent is injected into the anchoring hole to enable rock soil around the anchoring hole to form a static blasting reaming area; and an anchoring agent is injected along the anchoring hole, and the auxiliary device for the ultra-long anchoring cable deep hole bottom mounting, to which a traction rope is attached, is fed into the anchoring hole. By changing traditional orifice pushing of anchoring cable mounting into hole bottom reverse traction, the method has the advantages of being efficient to construct, safe in structure and the like.
本发明公开了一种用于超长锚索深孔孔底安装的辅助装置，包括锚固端、牵引端，锚固端为一倒圆台形锚固杆，牵引端包括滑轮，滑轮通过滑轮转轴与滑轮固定基座转动连接，滑轮固定基座固定连接在锚固端顶部，滑轮固定基座与锚固端连接端呈圆柱形，表面设置有与空心钻杆端部内壁的内螺纹相匹配的外螺纹。其安装方法包括：采用两种不同孔径的钻杆进行钻孔，形成大孔径的锚索孔和小孔径的锚固孔；往锚固孔中注入静力破碎剂，使锚固孔周围岩土形成静力爆破扩孔区；沿锚固孔注入锚固剂，将附上牵引绳的超长锚索深孔孔底安装辅助装置送入锚固孔中。本发明通过将锚索安装由传统的孔口推送改为孔底反向牵引的方式，具有高效施工、结构安全等优点。
