Method and device for internal refurbishment of corroded hollow sections
Abstract:
Corroded hollow sections, more preferably of orthotropic slabs, are cleaned and de-rusted on the inner surface with a rotating maximum-pressure water-jet continuously guided through the hollow section and angle-adjustable feeler-controlled corresponding to the respective interior surface region and capable of being throttled in critical regions. For the sealing of entering moisture and for corrosion protection as well as to improve the vibration behavior and the strength characteristics of the orthotropic slab, the cleaned and dried inner surface is holohedrally connected with a shapeable and stretchable fabric hose coated with a water-proof plastic in a sealing manner by means of an adhesive and using a pressure medium or a memory plastic hollow profile assuming its original shape under the effect of heat, wherein the internal pressure is maintained up to the curing of the adhesive.
