Abstract

The invention belongs to the field of geotechnical engineering supporting devices, and specifically relates to a connectable extension bolt for segmental anchoring, comprising a steel rod body, the left end of the steel rod body is sequentially provided with a truncated cone coaxial with the steel rod body body and Threaded column; the right end of the steel rod body is provided with an internal thread groove, a limit groove and several barbs. A segmented anchoring installation device that can be connected to an extended anchor rod, including a connecting rod, one end of the connecting rod is provided with a first hexagonal prism and a second hexagonal prism, and the first hexagonal prism is used for connecting with the first hexagonal prism The limiting groove engages, and the second hexagonal prism is used for engaging with the second limiting groove. The anchor rod of the invention has the advantages of large anchoring depth, section anchoring, high bearing capacity, convenient installation and the like. Compared with ordinary bolts, the length of the bolt disclosed by the invention is not limited by the space on the construction site; segmental anchoring can be realized, and the bearing capacity of the bolt can be fully utilized.

Description

technical field [0001] The invention relates to the field of support devices for geotechnical engineering and mine roadways, in particular to anchor rods for geotechnical engineering such as engineering slopes, tunnels, and mine roadways; in particular, it relates to a segmented anchor that can be connected to extend the anchor rod and its installation device. Background technique [0002] Anchor bolts are widely used in the support of geotechnical engineering, especially in the temporary or permanent support of mine roadways and the permanent support of various traffic tunnels; to prevent roadways or tunnel surrounding rocks deformation and collapse. [0003] The supporting anchor is the most basic equipment material in the current geotechnical engineering support, but the disadvantages of the traditional anchor are obvious: First, the length of the supporting anchor is generally It is fixed. In the actual application environment, there are many considerations in selectin...
