Description

Technical Field

[0001] The utility model relates to the technical field of rock anchoring, in particular to a rock anchoring structure. Background Art

[0002] Rock anchoring structure is a measure to stabilize fractured rock mass by using anchor rods or cables. Its main function is to cause additional stress and strain in the rock mass, thereby increasing the integrity, tensile strength, shear strength of weak surfaces and anti-sliding tangential force of the rock mass, thus stabilizing the rock mass.

[0003] The patent document with the prior art publication number CN211395668U provides a rock and soil anchoring structure, including an external sleeve rod, a limit plate, a fixing plate, a side anchoring assembly, a vertical anchoring assembly, a connecting plate and a rotating handle, wherein the bottom of the external sleeve rod is fixedly installed with a limit plate, the top of the external sleeve rod is fixedly installed with a fixing plate, the inside of the fixing plate is provided with a side anchoring assembly, the inside of the external sleeve rod is movably connected with a vertical anchoring assembly, the top of the vertical anchoring assembly is fixedly installed with a connecting plate, the top of the connecting plate is fixedly installed with a rotating handle, and the side anchoring assembly includes a baffle, a mounting plate and a side anchor head. The utility model improves the commonly used anchoring structure, and sets a side anchoring assembly and a vertical anchoring assembly, so that the rock and soil anchoring structure can greatly enhance its gripping force when in use, the structure is more stable, and the operation is simple and easy to implement, and has a broad development space and a high promotion value.

[0004] However, during the use of the existing rock anchoring structure, the worker will drill a hole at the position where the anchoring is required, and then insert the anchoring structure into the hole, and lock the anchoring structure in the hole through a tool. However, when locking the anchoring structure, although it can be fixed by expansion, the fixing force of this fixing method is small, resulting in poor fixing effect of the anchoring structure. For this reason, we propose a rock anchoring structure. Utility Model Content

When the expansion sleeve 5 moves backward, it will enter the expansion sleeve 6, and the expansion sleeve 6 will be expanded. The expansion sleeve 6 will be firmly fixed to the inner wall of the hole. At the same time, the expansion sleeve 5 will push the pushing head 901 of the reinforcement nail 9, and the reinforcement nail 9 will move outward, and the rock breaking head 902 on the reinforcement nail 9 will break the inner wall of the hole, thereby playing a fixing role and increasing the fixing force. This completes the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
