Description

Technical Field

[0001] The utility model relates to the technical field of anchor cable construction, in particular to an anchor cable positioning auxiliary device with an inner clamping adjustment structure. Background Art

[0002] Anchor cable is a tension member used in rock and soil reinforcement projects. It is mainly composed of three parts: anchor section, free section and tensioning end. The anchor section is the part of the anchor cable that penetrates into the stable rock and soil. It is tightly combined with the rock and soil through grouting and other methods, and transmits the tension to the surrounding rock and soil; the free section is the part located between the anchor section and the tensioning end. This part of the anchor cable can freely expand and contract when the rock and soil undergoes a certain deformation, mainly to transfer the tension of the tensioning end to the anchor section; the tensioning end is the part of the anchor cable used to apply prestress. The tensioning equipment is used to apply tension to the anchor cable, so that the anchor cable produces pre-compressive stress on the reinforced rock and soil.

[0003] When the existing anchor cable positioning device is in use, the anchor cable is inserted into a sleeve or casing. There may be some structures inside the sleeve or casing to prevent the anchor cable from sliding, such as a rubber gasket that can increase the friction between the anchor cable and the sleeve. However, the rubber gasket is not uniform enough to stabilize the entire anchor cable, and different rubber gaskets need to be replaced for use for anchor cables of different sizes, which reduces work efficiency.
