Modern methods of tunnels waterproofing and types of waterproof materials

ანოტაცია

The work describes, considers and systematizes new engineering and technical solutions of tunnels dewatering and waterproofing measures.

  Measures of the second direction (tunnel waterproofing) foresees provision of water impermeability of the tunnel support itself or rock massif surrounding the mine working that is achieved using the following methods:

- Tunnel support waterproofing through application of different insulating materials on its internal or external surface;

- Tunnel support water impermeability provision through support erection from water-proofing materials;

- Tamping of mountain massif and space behind the support.

Due to diversity of geological and hydrogeological features of mountain massifs the conditions of their intercrossing tunnels’ service-maintenance and operation are different and, in some cases, differ considerably from each other.
