ABSTRACTThe invention relates to a process and device for backfilling of aroadway structure of mine and tunnel construction utilizing support hosesfilled with a hardening filler. The hoses, when empty, are supported by theroadway support, after being put in place on the support are filled andthereby stretched out to form an inflated profile which locks onto the sup-port section. The process and device used has the advantages of not beinglimited to certain specific support structure spacings and may be applied toa variety of roadway sections. The support section has the general shapeof an I-beam and when used in multi-part roadway structures the sectionjunctions are protected against overloads even when they are designed withlimited yieldability. The support hose is laid on and supported over partof its length directly by the outer face of an "I" beam support sectionflange facing the rock. Where the flange supports the hose, the supportsection flange wholly or partly indents the cross-section contour of theinflated profile when the support hose is stretched out as it is filled withthe hardener compound.
