METHOD AND PLANT FOR PRODUCING A FIBERGLASS PROFILE TO BE USED AS REINFORCING ELEMENT FOR STRENGTHENING AN EXCAVATION WALL |
摘要 |
In the production of reinforcing elements for strengthening the excavation face of a tunnel, a fiberglass profile comprises an axially extending body formed by glass fibers anchored in a polymer resin through a polymerization process. The outer surface of this profile has a corrugated shape with respect to an axial cross- sectional plane of the profile. This corrugated trend is defined by a different degree of compression of the outermost glass fibers of the profile, made by a substantially thread-like element. |
