Patent ID: 8206529

Claim:
A method for the internal refurbishment of corroded hollow sections of orthotropic road slabs of steel bridges, characterized in that the inner surface of the hollow sections is cleaned and de-rusted with a rotating maximum-pressure water-jet continuously guided in a forward direction through the hollow section and angle-adjustable corresponding to the respective profile controlled by a surface feeler in rotation about the hollow section inner surface and capable of being throttled in critical hollow-section regions; and the cleaned and dried inner surface of the hollow section is holohedrally connected to a surface of a fabric hose in a sealing manner to the inner surface of the hollow section by means of a previously applied adhesive and under the effect of a pressure medium said fabric hose being saturated with a water-proof plastic under the effect of a pressure medium or a memory plastic hollow profile assuming its original shape under the effect of heat; and the adhesive is subsequently cured while the internal pressure is maintained.
