Grouting will be done to fill all voids in drypacking or elsewhere over the tunnel arch, toclose cracks, seams and fissures in the adjacentrock, and to increase the imperviousness ofthe concrete proper of the lining. To permitthis thorough filling grouting pipes, vent pipes,pipes for weepers and collectors were designedto be built into the concrete lining. Typicalarrangements of pipes are shown by Fig. this piping is entirely within the lining,the ends terminating Vz in. inside the surfaceand being fitted with plugs to prevent the con-crete from cov
