Abstract

The invention relates to an anchor rod structure, and relates to the technical field of anchor rod construction. The anchor rod structure comprises an anchor cable and an anchor plate arranged at oneend of the anchor cable inserted into an anchor hole, an anti-sinking part used for preventing the anchor cable from sinking is arranged on one side, far away from the anchor cable, of the anchor plate, one end of the anti-sinking part is connected with the anchor plate, and the other end of the anti-sinking part is provided with a pointed cone part. Due to the fact that the anti-sinking part is arranged on the anchor plate, and the anchor plate is temporarily fixed through the anti-sinking part, the problem that the anchor plate is prone to sink before the rotary spraying grouting slurry is initially set is solved. The anchor rod structure has the advantages that the arrangement position of the anchor cable is guaranteed, and the supporting effect is good.

Description

technical field

[0001] The invention relates to the technical field of bolt construction, in particular to a bolt structure and a construction method thereof. Background technique

[0002] Bolt support refers to a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as underground chambers such as tunnels and stopes.

[0003] At present, the casing follow-up method is generally used for anchor bolt construction. The construction process is: construction preparation, earthwork excavation, measurement and positioning, casing follow-up drilling, anchor cable production, anchor cable jacking installation, grouting and Subsequent tensioning. In weak geological places, such as silt formations, the phenomenon of hole collapse often occurs during drilling, and the selection of casing to follow up the construction process can effectively prevent the hole from collapsing. However, under the same anchoring force requirements, t...
