USING RESISTOGRAPH FOR TESTING SAFETY OF WOODEN POLES

Dijagnostika pri održavanju gradskih drvenastih nasada i drvoreda je dio monitoring i njege biljaka – stabala. Dosadašnja iskustva o trajnosti tj.sigurnosti stabala ili drvenih stupova temeljila sa na udaranje pri bazi i osluškivanje. Rezistograf je donio brojčanu vrijednost tj. zamijenjena je procjena. U ovom radu cilj je prikazati upotrebu instrumenta u ispitvanju sigurnosti stupova za instalacije. Instrument radi na principu bilježenja otpora kojim igla ulazi u srž stupa ili debla. Središnji dio rada je opis tehnike rada i analiza snimke stupa. U zaključku su prikazane prednosti postupka i njihova primjenjivost u sigurnost prolaznika ili sudionika u prometu.Diagnosis in the maintenance of urban woody plantations and tree lines is part of the monitoring and care of plants - trees. Previous experiences of durability, ie safety of trees or wooden poles, were based on hitting the base and listening. The resistograph gave a numerical value, ie the estimate was replaced. In this paper, the aim is to present the use of the instrument in testing the safety of columns for installations. The instrument works on the principle of recording the resistance by which the needle enters the core of the column or trunk. The central part of the paper is the description of the work technique and the analysis of the column image. The conclusion presents the advantages of the procedure and their applicability to the safety of passers-by or road users
