Abstract

The causes of water ingress of varying intensity during construction and operation of tunnel structures and adjacent facilities are analyzed in this article. The combined methods of performing grouting works in various geotechnical conditions are proposed, taking into account the intensity of water inflow into underground structures. The results of the study of the main technological parameters of grouting mortars on a mineral basis are presented.

Key words:

tunnel structures and adjacent facilities, water inflows, mineral-based grouting mortars, acrylate gels, hydroactive polyurethanes, composite binders, micro cements, bentonite mixtures
