The inspection and maintenance of road spikes is an important part of ensuring the safe operation of railway tracks. In order to promptly detect damage and loosening of road spikes, it is necessary to inspect road spikes regularly. Inspection methods include manual visual inspection and the use of special inspection instruments.
Manual visual inspection mainly observes whether there are cracks, deformation, rust, etc. on the appearance of the road spikes, and whether the connection between the road spikes and the rails and sleepers is loose. Special inspection instruments can more accurately judge the working status of road spikes by measuring parameters such as the tightening force and vibration frequency of the road spikes.
