Description

TECHNICAL FIELD

[0001] The utility model belongs to engineering quality detection technical field, concretely relates to an anchor rod locking force detection auxiliary device. BACKGROUND

[0002] The anchor rod is a reinforcing component widely used in many fields such as geotechnical engineering and underground structure support, and its main function is to transmit the pulling force to the stable rock-soil body or structure, to exert anchoring force on the reinforced object, thereby enhancing the stability of the rock-soil body or structure;

[0003] The appropriate anchor rod locking force can ensure that the anchor rod fully plays its reinforcing role, so that the rock-soil body or structure maintains a stable stress state, meeting the design requirements and safety standards of the corresponding project;

[0004] However, during the detection process, due to the misalignment of the detection device and the anchor rod position, the pulling force is no longer simply axial transmission during the transmission process, but will generate lateral component force, which makes the force value obtained by the detection device not the real anchor rod axial locking force, resulting in deviation of the detection data, and unable to accurately reflect the actual locking force of the anchor rod. The existence of lateral force will make the stress distribution around the anchoring segment and the connection part of the anchor rod and the detection device uneven, causing stress concentration. In this case, the anchor rod and the surrounding anchoring medium may be locally damaged when the load capacity is lower than normal, such as cracks in the anchoring segment concrete, local yield deformation of the anchor rod body, etc. This will make the current detection work unable to proceed smoothly, and may also cause the anchor rod to fail prematurely in subsequent actual use, unable to provide sufficient anchoring effect for the engineering structure, endangering the safety and stability of the entire project;
