CONSTRUCŢII <strong>SUB</strong>TERANE<br />

4. Concluzii<br />

Utilizarea noii tehnologii de refacere a unui podeţ, sub un<br />

terasament înalt, prin utilizarea unei umbrele de ţevi a constituit<br />

un succes deplin atât prin calitatea noii lucrări cât şi prin<br />

avantajele incontestabile faţă de tehnologia clasică cu săpătură<br />

deschisă şi poduri provizorii.<br />

Aceste avantaje sunt:<br />

- reducerea totală a tasărilor;<br />

- eliminarea închiderilor de circulaţie şi a perturbării<br />

traficului;<br />

- scurtarea duratei de execuţie;<br />

- reducerea costului;<br />

Avantajele enumerate mai sus, nivelul calitativ al noii<br />

lucrări şi experienţa câştigată sunt argumente importante în<br />

favoarea utilizării noii tehnologii şi în alte situaţii similare.<br />

4. Conclusions<br />

UNDERGROUND CONSTRUCTIONS<br />

The use of new culvert rehabilitation technology, under a high<br />

railway bed, using pipe jacking protection system has been an<br />

outright success in terms of both quality of the new construction<br />

and certain advantages towards the classic “cut-and-cover” and<br />

temporary bridge technology.<br />

These advantages are:<br />

• eradication of sagging<br />

• fewer traffic closures and decreased perturbation of<br />

traffic<br />

• shorter construction time<br />

• reduced costs<br />

The above advantages, combined with the high quality<br />

standards of the new work as well as the expertise earned<br />

throughout the construction process are important factors that<br />

plead for the use of new technology in similar situations.<br />
