SYNTHETIC RESIN COMPOSITE CONSTRUCTION AS A NEW CONSTRUCTIONAL SYSTEM FOR UNDERGROUND CAVITIES AND EXCAVATIONS

DER KUNSTSTOFF-VERBUNDVERBAU ALS NEUARTIGES AUSBANSYSTEM FUER HOHLRAEUME UND BAUGRUBEN

Synthetic resins, because of their high strength and deformability are very suitable for use in the new Austrian tunnelling method (NATM). Following a brief description of the NATM, the advantages of the epoxy resin anchor bonded to the epoxy resin coating over the shotcrete method are explained. Epoxy resin has a lower e modulus (lower build-up of resistant forces) a greater final strength a short hardening time (1 hour) and is impervious to water and gas. The composite material is produced from three components (base material, hardener, filler) for two applications (dowels, surface coatings), so that the thixotropy inhibits the flowing out of the material. The process described is particularly suited to swelling ground, semi-plastic and friable rock. Operational advantages result from unification of securing, propping, insulation and production of the inner lining in one operation (1 machine, 2 men). /TRRL/
