THE USE OF PLASTICS FOR THE SEALING OF TUNNELS, BRIDGES AND EARTHWORKS

PLASTICS ARE USED FOR SEALING IN THE FORM OF SHEETING OR SPRAYED COATINGS. FOR SHEET SEALING, PVC IS PREFERRED AT PRESENT AND POLYESTER RESIN FOR SPRAYING. SEVERAL METHODS HAVE BEEN DEVELOPED FOR THE APPLICATION OF SEALING SKINS OF SHEETING IN TUNNELS AND GALLERIES, WITH VARIOUS ENGINEERING AND ECONOMIC ADVANTAGES. THERE ARE MANY APPLICATIONS TOO FOR THE USE OF SEALING SHEETS FOR BRIDGES AND EARTHWORKS--IN THE LATTER CASE FOR THE STABILIZATION OF SLIPS IN EMBANKMENT AND CUTTING SLOPES. IN THE CASE OF SPRAYED SEALS, WHICH ARE OF SPECIAL ADVANTAGE IN THE CASE OF UNEVEN SEALING SURFACES, BITUMEN LATEX EMULSION IS A RECENT DEVELOPMENT WHICH PROMISES WELL. THE RESULTS WHICH HAVE SO FAR BEEN OBTAINED WITH PLASTIC SEALS ARE GOOD. /FG-RRL/
