Abstract

Inventia se refera la o ancora tubulara destinata a fi folosita la sustinerea rocilor în lucrari de constructii subterane sau de suprafata. Solutia tehnica asigura mentinerea sau marirea în timp a capacitatii de sustinere împiedicînd producerea proceselor de deformare sau degradare a stîncii. Asigura o capacitate de sustinere pe toata lungimea ancorei, astfel ca ea poate fi folosita la ancorarea rocilor atît în terenuri slabe cît si tari. Aceasta este rezolvata prin aceea ca, ancora, conform inventiei, este formata dintr-un corp conceput ca o teava cu perete subtire, avînd o parte frontala cu sectiune circulara cu rol de piesa de ghidare si o parte posterioara, care are în sectiune o forma ovala, iar perimetrele ambelor parti unul fata de celalalt sunt egale în acelasi timp cu perimetrul gaurii de ancorare.
