EFFECTS OF LOADS ON BURIED PIPES

INFLUENCE OF THE PIPE, THE SOIL AROUND IT, AND INTERACTION OF ANY SUPERIMPOSED LOADS ARE DISCUSSED ON THE STRUCTURAL PERFORMANCE OF PIPE. PIPES MUST SUPPORT LOADS RESULTNG FROM THE DEAD WEIGHT OF THE OVERLYING SOIL, AND MUST CARRY ANY ADDED LIVE AND STATIC LOADING PASSED DOWN THROUGH THIS OVERLYING SOIL FROM LOADS APPLIED ON THE GROUND SURFACE. THESE DEAD LOADS AND LIVE LOADS ARE DISCUSSED. FLEXIBLE AND RIGID PIPES ARE DESCRIBED IN REGARD TO THEIR STRENGTH AND FLEXIBILITY. DITCH WIDTH, BEDDING, COMPACTION, AND BACKFILL ARE DISCUSSED. PRECAUTIONS NECESSARY TO PREVENT INFILTRATION OF MATERIAL IN AN INSTALLATION ARE DESCRIBED. CONDITIONS PRESENT IN AN INSTALLATION FOR INFILTRATION OF MATERIAL TO RESULT ARE: (1) HIGH WATER TABLE, (2) BACKFILL MATERIAL CONTAINING FINE PARTICLES THAT CAN BE MOVED BY PERCOLATING WATER, AND (3) GAPS AT PIPE JOINTS OF SUFFICIENT SIZE TO PERMIT ENTRANCE OF MATERIAL CARRIED OR MOVED BY SEEPAGE. GREAT CARE SHOULD BE TAKEN WITH ALL JOINTS AND ALIGNMENT TO PREVENT INFILTRATION.
